UPDATE:
Some more things I tried to get the tiddler to render correctly
(unsuccessfully):
- Running a function to delete the tiddler and recreate it with exactly
the same values had no perceivable change. There was no visible change
whatsoever. I wouldn't know the function had run or not if it weren't for
the console log.
- Running a function to close, delete, recreate, and re-open the tiddler
in quick succession had no effect.
- Running a function to add the tiddler to the list, close and re-open
the tiddler, then close and re-open the second tiddler works as explained
above but isn't a real solution.
It appears no matter how many close, open, delete, create or other actions
I string together into a single function (or by adding additional action
widgets to a button widget), the effects of the change don't actually
render (i.e. they happen, just aren't visible) until all actions are
completed. Can anyone confirm this?
This being the case, is there a way to manually trigger the syncer
dispatchTask (for example) so it renders between different actions?
I'm just shooting in the dark at this point.
