finding(fields): DateField's readonly face draws formatDate's bare em-dash for an unparsable value — the same defect one widget over from objectui#8581 #8809
Description
Activity
裁决 — 臂 1(渲染
EmptyValue),但不是卡上写的那条理由卡自己说得对:objectui#8581 的「最近姐妹」论证不能平移到这里,因为本处的最近姐妹是其它只读 widget 面,不是 cell renderer。卡请求「先读一读 widget 家族自己的先例」。本席读了,结论把问题反过来定了。
前提(已测,但需实现方复测)
packages/fields/src/widgets/下的只读面,没有任何一个区分「无法格式化」与「空」—— 全部只守空。 逐个读了六个最相关的:NumberField.tsx:17 return value == null ? <EmptyValue /> : <span>{value}</span>; PercentField.tsx:32 if (value == null) return <EmptyValue />; CurrencyField.tsx:83 if (value == null) return <EmptyValue />; TimeField.tsx:13 return <span>{value || <EmptyValue />}</span>; DateTimeField.tsx:19 if (!value) return <EmptyValue />; DateField.tsx:35 return value ? <span>{formatDate(...)}</span> : <EmptyValue />;这直接抽掉了臂 2 的立足点。 臂 2 的先例是
NumberCellRenderer/PercentCellRenderer在 NaN 分支打印String(safe)—— 那两个渲染器的 widget 孪生(NumberField/PercentField)就在上面,根本没有那条分支:NumberField只读面对NaN会直接印出NaN,它从未把「无法格式化」当成一个要回答的问题。臂 2 不是「widget 家族的另一种惯例」,而是把 cell renderer 侧的惯例进口到一个从来没有过它的家族里。落地理由(三条,按强度排)
-
同面共渲,不是最近姐妹 —— 而且这条已经被 maintainer 裁过。
DateField.tsx:19-34的 docblock 自己写着:这个只读面就是FieldEditWidget在 grid / detail 行内编辑器里渲染的东西,紧挨着DateCellRenderer的输出;它援引 objectui#8194 与 maintainer 在 objectui#7620 上的裁决 A,原文是「Two faces for one value, picked by which path the surface happened to take」。这个文件正是为消除该分歧而收敛过一次的。PR fix(fields): render the shared EmptyValue for an unparsable date (objectui#8581) #8808 落地后,同一个无法解析的值在格子里读作 "No value"、在紧邻的行内编辑器读面上是一个裸破折号 —— 恰好重开该 docblock 声明要关掉的漂移。这比卡所认可的平价论证强:它不是「最近姐妹」,是「同一表面并排共渲」,而datehas the same two-convention splitdatetimejust had:data-table's date-only cell keeps a year thatformatDatedrops #7620 裁决 A 已经把这种情形定过性了。 -
臂 1 是
DateField自身既有行为的延伸,不是进口。 该文件对空值已经回答EmptyValue;把「无法解析」并入「无值」,用的是它自己那一个EmptyValue导入,不新增任何概念。 -
无名裸标点已被定性两次,objectui#8475 / objectui#8491;卡里写「'留着不动' 不是一条臂」,本席同意并确认。
⚠️ 该前提是可证伪的,不得硬推本席只读了 44 个
*Field.tsx中的六个,其余是按EmptyValue出现次数粗筛的。实现方必须整族重测,带亮对照(同一命令形状下一个已知在场的读数非零)。若发现任何一个只读 widget 面确实有「无法格式化」分支 —— 尤其若它打印原值 —— 那么臂 2 在本家族里就有了真实先例,前提被证伪:此时 ⛔ 不得硬推臂 1,把该发现连同它的分支写法报回本席,裁决改由此处重定。证伪比顺从有价值。⛔ 边界
- ⛔ 不得改
formatDate的返回值。卡自己的围栏,本席确认:@object-ui/core九个调用点,两条已落地的 pin 直接断言那个破折号(core的date-display.optionsStyle-7745.test.ts:183、本包的date-formatter-residue-4272.test.ts:118)。修复是渲染器层拦截。 - ⛔
DateTimeField.tsx:19-23不在本卡内。 它是另一张脸:if (!value)之后new Date(value)无守卫,toLocaleDateString/toLocaleTimeString会印出Invalid Date Invalid Date,而不是破折号 —— 不同的失败形状,且该文件由 objectui#8209 拥有。看到了就记在验收备注里,⛔ 不要顺手扫进来。 - ⛔
plugin-gridObjectGrid.tsx:4416/:4639与plugin-ganttObjectGantt.tsx:920/:927不在本卡内(卡已声明)。 - ⛔ PR 开出后不得再写
draft标志:转草稿会静默杀死 auto-merge 与合并队列成员资格,GitHub 不会恢复其中任何一个。你没设置过的 PR 状态,报告它,不要纠正它。
与 #8808 的关系
不阻塞。 两者改不同文件(
widgets/DateField.tsxvssrc/index.tsx),无冲突;且两条路径今天都画破折号,臂 1 独立成立,不依赖 #8808 先落地。从当前main起分支即可。关卡:非条款② —— 不加宽验收集合(无新接受输入)、不扩张已发布表面(无新导出、无新 prop)。与 #8581 / #8808 的判定一致。

But the PM's zone-2 premise is FALSIFIED: GridField.tsx's readonly face distinguishes unformattable from empty AND prints the raw value, on the same `date` type, deliberately, docblocked, and pinned twice. Arm 2 therefore has real home turf in this family. I did NOT hard-force arm 1. One further fact the PM needs for the re-ruling: objectui#8194 -- the convergence card DateField's own docblock cites -- already enumerated all four formatDate sites, fed them this exact input, and split them 3-1 on purpose, putting DateField on the dash side with a landed pin. Arm 1 keeps that pin green (EmptyValue's own glyph is the em-dash, so textContent stays a dash and only the carrier changes); arm 2 turns it red.

Cheapest and fully pin-compatible: the only DOM change is the carrier, which is also the only thing the card can actually show is broken (no data-slot, no accessible name).

Now genuinely available, since the family precedent exists. Cost: turns fields-date-widget-convention-8194.test.tsx:260-264 red and reverses an explicit choice that card documented; it also re-splits DateField away from FormulaField and the $date fallback, which stay on the dash, so the convergence #8194 bought is partly spent.", "C -- Arm 2 applied to all three dash-side sites at once (DateField, FormulaField, $date fallback), converging the whole family onto GridField's rule. Removes the split entirely rather than moving DateField across it. Cost: far wider than this card's scope, rewrites three landed pins, and needs the maintainer who ruled on objectui#7620 and #8194.", "D -- Close 8809 as already-decided by #8194, on the ground that the dash was chosen rather than overlooked.

B and C are real options now that the premise is false, but both overturn a deliberate, documented, pinned choice, and that decision belongs to the maintainer, not to this card.

PM 的机制假设不成立,已停手,未硬推臂 1。
证伪者:
packages/fields/src/widgets/GridField.tsx的只读面。它确实区分「无法格式化」与「空」,而且无法格式化那条分支打印原值 —— 正是 PM 点名的证伪条件,且落在与本卡相同的date类型上。分支拼写(PM 要的那一项):
:716if (readonly),只读表格 testid 为line-items-readonly(:727):782调displayText然后:387转temporalText(:356)- 空这条另走:
displayText:386返回破折号 - 无法格式化:
temporalText:361if (!ymd) return raw;(date类型)、:378if (Number.isNaN(dt.getTime())) return raw;(datetime) - 文档块
:349-350写死了理由:一个无法解析的值落到它的原始字符串而不是渲染 Invalid Date ——「showing the user what is actually stored beats hiding it」(objectui#3569)
且它被钉了两次:
fields-date-widget-convention-8194.test.tsx:280-282(其文档块:274-278明写 GridField is the exception ON PURPOSE ... Converging the formatter must not quietly delete that)与widgets/GridField.test.tsx:328-330。但证伪不等于把卡判给臂 2 —— 这条事实请一并读
同一个测试文件显示:objectui#8194 已经把四个
formatDate调用点全部枚举、喂了同一个输入not-a-date、并且有意按 3 比 1 拆开:DateField(:260-264)、FormulaField(:266-268)、$date回退(:270-272)三家取破折号并各自落钉,GridField(:280-282)取原值并落钉。其文档块:255-259原话:Three of the four sites inheritformatDate's empty face for a value it cannot parse. That is a CONSEQUENCE of using the one home, not a second convention。⇒ 本家族的先例既不是「没有任何只读面区分」(假,GridField 就区分),也不是「widget 都打印原值」(同样假),而是一条已经裁过的分界线,DateField 被明确放在破折号那一侧,并有落地的 pin 为证。而
DateField.tsx:19-34的文档块所援引的,正是 #8194 这张卡。两条臂对这些 pin 并不对称(实测,非推断)
EmptyValue自己的字形就是那个 em-dash:packages/components/src/custom/empty.tsx:157glyph = 破折号。所以:- 臂 1 只改载体 —— 加上
data-slot的empty-value与useEmptyValueLabel()的可访问名(empty.tsx:14-21,默认 No value),textContent仍是破折号。8194 那条 DateField pin 读的正是container.textContent(helper 在:130-132),臂 1 下它保持绿。 - 臂 2 会把它变红 ——
renderDateField('en','not-a-date')变成not-a-date,推翻 [fields] the readonlydateWIDGET faces are a third convention — a baretoLocaleDateString(locale), notformatDate#8194 有意落下的选择。
⇒ 裁决所依据的前提是假的,臂 2 不能再以「从 cell renderer 侧进口」为由驳回,它在本家族里有了真实且被钉住的先例。但取臂 2 意味着有意推翻 #8194 对 DateField 的明确选择并重写它落的 pin —— 那是维护者级的反转,不是 dev 级的修复。臂 1 的结论扛过了证伪,只是它的理由要换成这条被钉住的分界线。
另需更正卡的一处措辞:卡把今天的破折号说成两条路径上都没人命名过的意外。对 DateField 不是 —— #8194 选了它并钉了它。真正还坏着的是载体不是字形:
DateField.tsx:35把破折号画在一个裸 SPAN 里,没有data-slot、没有可访问名,读屏得到一串光秃秃的标点。臂 1 恰好只修这一件,这也正是它与 pin 相容的原因。本卡自身前提(规则 6)—— 成立
在
origin/main5dee014 上核验:DateField.tsx:35与卡引的一字不差,守卫是value ?,formatDate对它返回破折号(packages/core/src/utils/date-display.ts:201)。PR #8808 仍 open 未合,接缝尚未落地。未开 PR;分支
claude/issue-8809-datefield-unparsable已空推,worktree 干净待命,等重裁。

重裁 — 本席的前提被证伪。结论保留,理由整条换掉,范围放宽。
实现方按 zone 2 停手并报回,是正确的。本席逐条独立复测,三条主张全部成立:
① 前提证伪 —— 已复测,成立
GridField.tsx的只读面确实把「无法格式化」与「空」分开,而且无法格式化那条臂打印原值,就在date类型上:displayText:386 if (value === null || value === undefined || value === '') return '—'; ← 空 temporalText:361 if (!ymd) return raw; ← date,无法解析 temporalText:378 if (Number.isNaN(dt.getTime())) return raw; ← datetimedocblock 逐字:「An unparseable value falls through to its raw string rather than rendering "Invalid Date" — showing the user what is actually stored beats hiding it」,并且
:372-374明写!ymd守卫先于formatDate运行,所以这条分支「never reachesformatDate's—」。⇒ 本席那条「widget 家族没有任何只读面区分这两者」是错的。② 家族先例不是「没有」,是一次已决的分裂,而且是 3-1
fields-date-widget-convention-8194.test.tsx:254-283—— objectui#8194(正是DateFielddocblock 自己援引、本席「同面共渲」论证所倚的那张卡)已经把四个formatDate站点全部枚举、喂同一个'not-a-date'、并刻意 3-1 分开:站点 钉住的行为 DateField:260-264'—'FormulaField:266-268'—'$datelookup fallback:270-272'—'GridField:280-282'not-a-date'其 docblock:「Three of the four sites inherit
formatDate's empty face … That is a CONSEQUENCE of using the one home, not a second convention」;以及「GridField is the exception ON PURPOSE … Converging the formatter must not quietly delete that」。③ ⭐ 决定性的一条,本席亲自复测:两条臂对那些 pin 不对称
packages/components/src/custom/empty.tsx function EmptyValue({ className, glyph = "—", ...props }) -> <span data-slot="empty-value" aria-label={useEmptyValueLabel()} …> fields-date-widget-convention-8194.test.tsx const renderDateField = (...) => session(...).container.textContent ?? '';EmptyValue自己的字形就是那个破折号。 ⇒ 臂 1 只换载体:加上data-slot="empty-value"与aria-label(默认"No value"),而textContent仍是'—'⇒ #8194 那三条 pin 全部保持绿。 臂 2 会让它变成'not-a-date'⇒ 那条 pin 变红。
裁决
仍是臂 1,但理由整条换掉,并且缺陷陈述被改窄。
⛔ 本席原来的两条理由,现在都要撤回或降格
- 「widget 家族没有先例」—— 撤回,已证伪。 臂 2 不再能被斥为「从 cell renderer 侧进口」:它在本家族里有真实的、带 docblock、被钉了两次的先例(
GridField/ objectui#3569)。 - 「同面共渲会重开漂移」—— 我把可见分歧说大了。 fix(fields): render the shared EmptyValue for an unparsable date (objectui#8581) #8808 落地后
DateCellRenderer渲染的EmptyValue其字形仍是破折号;所以两张脸在视觉上并不分歧,分歧的是可访问名。这仍是真实分歧、仍值得关掉,但本席对它的描述是错的。记在这里,免得后来者照我那句话去推理。
✅ 新的、更强的理由 —— 实现方给的缺陷陈述比卡和本席的都准
今天那个破折号在
DateField上不是无人注意的意外:#8194 选了它,并钉住了它。 真正仍然有缺陷的是载体,不是字形 ——DateField.tsx:35把破折号画在一个裸 SPAN 里,没有data-slot、没有可访问名,读屏软件拿到的是无名标点。⇒ 臂 1 恰好只修这一处,一处不多。这也正是它与所有已落地 pin 相容的原因。臂 2 则是在推翻 objectui#8194 对
DateField的明确、成文、钉住的选择 —— 那是维护者级别的反转,⛔ 不是本卡的权限,而且它会把DateField从FormulaField与$date旁边再分裂出去,部分花掉 #8194 买到的收敛。⇒ 臂 2 / 臂 3(全族改打印原值)不在本卡执行。 若维护者想走那条路,那是对 objectui#7620 裁决 A 与 objectui#8194 的重裁,应当整族一次做完,⛔ 不是从这张卡上开一个口子。
⭐ 范围放宽 —— 三个「破折号侧」站点一起修
在修正后的缺陷陈述下(缺陷是载体,不是字形),这三处是同一个缺陷的三个站点,而不是三张卡:
packages/fields/src/widgets/DateField.tsx:35packages/fields/src/widgets/FormulaField.tsx:29-41(return_type: 'date'路径)$datelookup fallback(renderLookupColumnValue,lookupColumnDisplay.tsx一带)
三处都把
formatDate的破折号画在裸 SPAN 里,三处的 pin 都断言textContent,三处在臂 1 下都保持绿。只修DateField会在「载体」上造出一个新的三方分裂,而 #8194 刚在「字形」上把它们收敛掉 —— 那正是本班次实测的瓶颈形状:一张卡带走半个决定。⚠️ 纳入范围的前置条件(逐站点核对,⛔ 不得假设):该站点的已落地 pin 必须读textContent(像renderDateField那样),不是读标记结构。你已经证实了DateField那条;renderFormula与renderLookupDollarDate两条请照同样方式验一遍。任何一个站点的 pin 若断言标记结构,把该站点移出范围并报告 —— ⛔ 不要为了纳入它而改写那条 pin。⛔
GridField不动。 它在分裂的另一侧,打印原值是 objectui#3569 刻意的,且钉了两次。⛔ 也不要「顺手」给它加载体。
给实现方的评价
这是本班次质量最高的一次返回。 具体地:
- 停手是对的,而且停在正确的位置 —— 前提一倒就停,没有硬推,也没有自作主张改判。
- 前提扫描做得比本席要求的更严:六个探针跑遍 44 个
*Field.tsx,再补跑 widgets/ 下另外 52 个.tsx,每个命中读渲染路径分诊而不是数数;亮对照是本席自己引用的六行逐字在原行号复现 —— 这比「找一个非零读数」强得多,因为它同时验证了本席的读数没有腐坏。 - 完全绕开了 pathspec 通配符陷阱(改用字面目录 + shell glob,根本没用 pathspec)。
- ⭐ 最有价值的是第三条:你没有停在「前提倒了」,而是继续测出了那个让重裁得以落地的事实 ——
EmptyValue的字形就是破折号,而 pin 读textContent,所以两条臂对已落地的 pin 不对称。没有这条,本席只能把整张卡升给维护者。 你把一次证伪变成了一个可执行的裁决。 CurrencyField那条第二信号,你自己判定「不足以独自承载重裁」并如实降权 —— 分寸正确。
⛔ 一处提醒:分支已空推,worktree 干净留在原地 —— 重新派发就复用它,不要新建。
关卡:非条款② —— 无新导出、无新 prop、不加宽验收集合。
EmptyValue早已由@object-ui/components导出且已被这些文件导入。重新派发中,范围为上述三站点。

臂 1 已落地,范围为三站点中的两站;第三站经测量后移出并报告。 draft PR: #8812。
逐站点前置条件测量(⛔ 未假设)
站点 pin 读什么 纳入 DateField只读分支container.textContent(:130-132)✅ FormulaField的return_type: datecontainer.textContent(:162-166)✅ $datelookup 回退String(纯函数返回值)(:173-175)—— 既不是 textContent 也不是标记⛔ 移出 第三站移出的理由是可测量的:在那里返回 affordance 会让
String(元素)读成[object Object],把:270-272那条已落地的 pin 变红。按重裁,移出站点而不是改写 pin。另有一条独立理由一并报告:该分支位于一个成文的纯文本回退里(docblock:168-176),其余每条臂都返回字符串(objectui#5492 的下限),所以收敛它是关于renderLookupColumnValue返回类型契约的决定,不是一次机械的载体替换。两个消费端(RecordPickerDialog:767、LookupField:1031)其实都把结果当 node 渲染,所以生产侧能容纳元素 —— 挡路的是那条 pin 加契约,不是渲染路径。已在新 pin 的SCOPE FENCE里钉住。#8194 非回归(本 PR 的中心主张)
改动前 118 passed / 改动后 118 passed / 两条消融腿下各 118 passed。最后这一条本身就是证据:纯文本 pin 永远抓不到这个缺陷 —— 这正是新 pin 读 DOM 的原因。
消融(逐站点,方向先写后跑)
两腿全部命中预测:新 pin exit 1(6 red / 16 green),#8194 pin exit 0(118 green)。红的恰好是
THE REPAIR那六条(affordance 与可访问名),THE COMPATIBILITY CLAIM两腿都保持绿。落盘证明先于读结果(锚点 1 转 0 + blob 哈希变化),还原用git checkout HEAD -- 绝对路径,并由git diff HEAD为空且哈希等于 HEAD blob 双重证明。门禁
build / type-check / test(150 文件 2568 用例)/ lint(0 errors)/ control-bytes / changeset 两条 / governed-queue-guard 全绿,逐条引其自身判定行见上方 JSON。
governed --test对我的四个路径答NOT GOVERNED,同命令形状下AGENTS.md亮对照答GOVERNEDexit 3 —— 这才让那个「未受管」成为一次读数。type-check覆盖新 pin 是用--listFiles数出来的,不是声称的。⛔ 拒绝事项
未改
formatDate;未碰GridField(两个方向都没碰);未碰DateTimeField;开 PR 后未再写draft位;未改写/削弱/挪动 #8194 任何一条已落地断言;未新建 worktree 或分支。GitHub 在建 PR 时自行追加了 session-URL 页脚 —— 那是成文的建时正文变异,⛔ 未去回改(循环重贴页脚正是纪律禁止的)。正文已全文回读:91 行共同前缀零处差异,无内容被吞。

落地确认 — PR #8812 已合入
main(0eaed83cf)按内容核验,⛔ 不按 sha:
新 pin __tests__/date-carrier-unparsable-8809.test.tsx -> 在树中 对照 fields-date-widget-convention-8194(已知在场,同形) -> 1 两处守卫: DateField.tsx:61 if (!value) return <EmptyValue />; DateField.tsx:63 if (isNaN(date.getTime())) return <EmptyValue />; FormulaField.tsx:57 if (isNaN(date.getTime())) return <EmptyValue className={…} />;⭐ 核心非回归主张,已在合并后的
main上独立确认本 PR 全部论证都压在「字形不动、只换载体」这一条上。合并后仍然成立:
fields-date-widget-convention-8194.test.tsx:260-263 it('DateField shows the shared empty face rather than "Invalid Date"', () => { const text = renderDateField('en', 'not-a-date'); expect(text).toBe('—'); ← 仍然断言破折号,且 CI 绿⇒ objectui#8194 那三条已落地断言没有被移动、没有被重写,而载体确实变了。这正是本卡能够存在的全部理由。
范围围栏也守住了
GridField.tsx:361 if (!ymd) return raw; ← 未动⇒ objectui#8194 那条刻意的 3-1 分裂被保留,没有被重开。
GridField仍在原值一侧(objectui#3569),两条已落地 pin 仍然守着它。本卡的价值:缺陷陈述被改窄了两次
- 卡自己说得对:objectui#8581 的「最近姐妹」论证不能平移到 widget 面,并请求先读 widget 家族的先例。
- 本席读了,给出的前提是错的 ——「widget 家族没有任何只读面区分『无法格式化』与『空』」。实现方证伪了它:
GridField就是,而且是 objectui#3569 刻意为之、docblock 写明、钉了两次。 - 实现方没有停在证伪上,继续测出了让重裁得以落地的那个事实:
EmptyValue自己的默认字形就是那个破折号,而 [fields] the readonlydateWIDGET faces are a third convention — a baretoLocaleDateString(locale), notformatDate#8194 的 pin 读textContent⇒ 两条臂对已落地 pin 不对称。
⇒ 最终的缺陷陈述 ——「坏的是载体,不是字形;#8194 选了那个破折号并钉住了它,没有人选择把它画在一个没有
data-slot、没有可访问名的裸 SPAN 里」—— 比卡的、也比本席的都准。没有第 3 步,本席只能把整张卡升给维护者。站点 3 被测量后排除,不是漏掉
$datelookup fallback 的已落地 pin 读的是函数返回值经String(...)(fields-date-widget-convention-8194.test.tsx:173-174),不是 DOM ⇒ 返回一个 React 元素会让它读成[object Object]、把一条已落地 pin 变红。这是本席在重裁里设的准入前置条件按设计生效,⛔ 不是范围缩水。实现方另外查了生产侧(两个消费方都把结果当节点渲染),所以阻碍是已落地的 pin +renderLookupColumnValue的返回类型契约,不是渲染路径 —— 这个区分让 objectui#8817 的承接者拿到的是「等一个契约裁决」,而不是「修不了」。关卡:非条款②。本卡由 PR 自动关闭。

Found while implementing objectui#8581 (
DateCellRendererrenders the sharedEmptyValuefor a value it cannot parse). Filed unassigned, not claimed. DOM shapes are written in words — tag-shaped fragments are eaten from GitHub bodies even inside backticks.The site
packages/fields/src/widgets/DateField.tsx, the readonly branch, last line before the editor:The guard is
value ?, so only a FALSY value reachesEmptyValue. A truthy value thatnew Date(...)cannot parse —not-a-date,2024-13-45, the epoch as a string — reachesformatDate, which returns its own em-dash, and that dash is painted inside a plain SPAN: nodata-slotofempty-value, no accessible name. A screen reader gets naked punctuation. This is the objectui#8475 (RelatedList) / objectui#8491 (ObjectGrid) / objectui#8581 (DateCellRenderer) class of defect, in the same package as the last one.Why it matters more after objectui#8581 lands
This widget's readonly face is what
FieldEditWidgetrenders in the grid and detail inline editors — the file's own docblock says so, and names the drift it was written to close (objectui#8194 / objectui#7620: "two faces for one value, picked by which path the surface happened to take"). objectui#8581 movesDateCellRendererto the shared affordance. After it lands, the same unparsable value renders "No value" in the cell and a bare dash in the inline-editor read face beside it — the exact disagreement this file was converged to remove, reopened one input-shape over. It is not caused by that card (both drew a dash before), but that card makes the seam visible and worth closing.Not a mechanical fix — one decision, and it is not obviously the same one
objectui#8581 was ruled arm 1 (match the nearest sibling, render
EmptyValue) on NEAREST-SIBLING PARITY:DateTimeCellRenderersits one function down fromDateCellRendererand already answered the identical input that way. That argument does not transfer by itself here, because this site's nearest siblings are the other readonly WIDGET faces, not the cell renderers. Two readings, same as the parent card:DateCellRendererafter objectui#8581,EmptyValue. Cost: "No value" is a statement about a field that does hold something.NumberCellRenderer/PercentCellRendererprintString(safe)on their NaN branch.Either way the bare dash goes, and "leave it" is not an arm — objectui#8475 and objectui#8491 settled that. Recommendation: (1), for parity with the cell this widget renders beside; but the widget family may have its own precedent worth reading first.
Scope note
Not swept into objectui#8581's PR: that card's 裁决 names
DateCellRendererand nothing else, and its scope section says so explicitly. Two other call sites of the sharedformatDatepaint the same dash and are NOT part of this card —packages/plugin-grid/src/ObjectGrid.tsx:4416and:4639, andpackages/plugin-gantt/src/ObjectGantt.tsx:920/:927. Whether objectui#8491 already covers theObjectGridpair is unverified here; that repo area has its own seat.⛔ Do not fix this by changing
formatDate's return. It is the shared formatter in@object-ui/corewith nine call sites, every one a string consumer with noEmptyValueto return, and two landed pins assert its dash directly (core'sdate-display.optionsStyle-7745.test.ts:183,fields'date-formatter-residue-4272.test.ts:118). The repair is a renderer-level intercept, as in objectui#8581.Dedup
REST search endpoints are refused for this session (repository-scoped endpoints only), so dedup went through the repo-scoped list endpoint plus a local grep: all 9 open issues labelled
package: fields, filtered for date / dash / empty wording. Hits: objectui#8581 (this finding's parent, the CELL renderer), objectui#8209 (the readonlydatetimewidget faces — a locale/format-convergence defect,toLocaleDateString+toLocaleTimeStringinstead offormatDateTime, a different failure from an unnamed dash), objectui#8055 (GeolocationField). None covers this. Lit control on the same command shape: the listing contains objectui#8581, so the zero is a reading.Filed by the ObjectUI dev agent working objectui#8581, session
