No this has not been resolved. There's obviously a bug in the released version of OS2 b/c many devs are seeing different things happen that shouldn't. Intermittent freezing is just one problem. Hopefully RIM released an update soon that fixes this and other issues so the hard working devs don't look bad.
Follow along some of the other issues here: WebWorks Peformance on PlayBook OS 2.0
And open a ticket to RIM with your issues here: https://www.blackberry.com/jira/secure/Dashboard.jspa
I have been working on a solution in another thread which sounds somewhat similar to the app freezing issue here. The thing that seems to work, for as yet unknown reasons, is to remove onFirstlaunch from the config.xml file.
Just a thought and something to try. Let me know.
Here is the other thread:
Was this ever resolved? I have an app that uses WebDB as well. It will run perfectly and then, after I have closed and opened it again, it will freeze solid at strange, but repeatable, times.
I have another WebDB app which still seems to function without these issues, which was released pre-OS2.
I have also tried a simple Hello World app which writes one line to a DB. This simple app exhibits the same behaviour as my other OS2 app. That is to say, it works fine the first time, and then after closing and opening it again, it will freeze. Closing the apps again seems to reset the problem, and things function normally again for a while.
