Markdown checkboxes uncheck themselves upon Synchronization

[deisner]

Environment

Joplin version: 1.0.165 (prod, win32)
Platform: Windows
OS specifcs: Windows 10 Enterprise

Steps To Reproduce

1. Create a new note (Ctrl + N)

2. Create a few checkbox items with Markdown (e.g. * [ ] Here is an item).
   

3. Check-off a checkbox:
   

4. Wait for Joplin to Syncrhonize.

Describe what you expected to happen:
I expect the checkbox to remain in the checked state after Joplin synchronizes, but what happens instead is it unchecks itself:

Logfile

webdev console:

Last 500 lines of log.txt:

log-tail-500.txt

I'm sorry to say, but this is not a bug. At least not the one you think.

The markdown code for a check box item is - [ ] not * [ ]. If you change it to the correct format, it will work.

So the real bug is that * [ ] is even rendered as a checkbox. @laurent22 do we want to look into this or are we closing it as invalid?

[laurent22]

Yes let's leave it open. I'll change the plugin so that it doesn't render that markup as a checkbox to make it less confusing. Only supported syntax is with a dash.

Thanks for the quick reply. I understand.

This context might help: I had nested list items that included links to external web pages, and I wanted to check-off which pages I'd read. So the * [ ] markdown came from a desire to add a check box to the beginning of some bulleted items -- the asterisk was part of a nested list.

I could have done something like this, instead, then:

However, I'm now thinking that this might also be a bug. Is the intended behavior to only permit a checkbox at the beginning of a line?

Nested checkboxes look like this:

- [ ] Checkbox 1
    - [ ] Checkbox 1.1
    - [ ] Checkbox 1.2
- [ ] Checkbox 2

checkboxes have to stand on their own. They can't be added or included in any other markdown. e.g. checkboxes in tables don't work.
