Description
The Obsidian Calendar Event Item Occurrence List block (Rock.Blocks/Event/EventItemOccurrenceList.cs) does not use the friendly route of the configured Registration Instance Page when linking to a registration instance.
Actual Behavior
On the Event Detail page (web/calendars/{id}/event/{id}), the "Calendar Event Item Occurrence List" block (Obsidian, BlockType 356, instance 656 on page 396) renders a grid of event occurrences. Its Registration column links to the configured Registration Instance Page (page 404) — but always as the fallback URL /page/404?RegistrationInstanceId=XYZ instead of the friendly route /RegistrationInstance/XYZ, even though page 404 has that route configured.
Root cause (in Rock's core block code, Rock.Blocks.Event.EventItemOccurrenceList):
Server-side, the block builds the base URL via GetLinkedPageUrl( "RegistrationInstancePage" ) without passing any parameters. Rock's PageReference.BuildUrl() only uses a page route when all of the route's {parameters} are supplied — with zero parameters, route matching fails and it falls back to the literal page/404.
Client-side (eventItemOccurrenceList.obs), the Registration link then hard-codes the ID as a query string: href = registrationInstancePageUrl + "?RegistrationInstanceId=" + row.registrationInstanceId.
Result: https://rocksolidchurchdemo.com/page/404?RegistrationInstanceId=QDAjpxdjB5 — correct destination, wrong URL shape. The setting pointing to page 404 is correct; the block simply never engages the route system for this link. (Notably, the same block does it correctly for row-click navigation to the occurrence Detail page, passing a ((Key)) placeholder through route substitution.)
Expected Behavior
Accessing the registration instance from any other block seems to work. Such as the Calendar Item campus Detail.
