I have an iOS app that uses a few live queries and they all work quite
well, except the first time the app is launched. My app is a basic CRUD app
showing CBLModels in lists. The app starts with an empty table backed by a
CBLUITableSource. Nothing else can happen until at least one CBLModel is
added to that list. Any CBLModels I add are persisted, but the livequery
backing the list never gets notified of any changes. But this ONLY happens
on first launch. If I kill the app and restart it, the models I added
appear in the list and the live query works from then on. I can add,
delete, edit to my heart's content and all of those changes will be picked
up by the live query. Its only the first time that it never works. I've
turned on verbose debugging and I don't see any errors. I've attached two
logs, one that shows what happens on first launch and another that shows
what happens on the second launch.
I also tried launching the app once, then killing it and restarting before
adding my first model, and it worked fine. What is happening here?
