BlackBerry "symbol integer.valueof not found" error when starting app on simulator

Question

Not sure what happened here, I added some new code and now I'm getting this error when trying to run the app on the BlackBerry simulator from Eclipse.

From the console:

[0.0] Starting MyApp
[0.0] Symbol 'Integer.valueOf' not found.[0.0] Error starting MyApp: Symbol 'Integer.valueOf' not found.

This appears both in the debugger and on-screen as a popup with an "OK" button.

Any help at all? I can't think of anything which I changed to cause this to happen. Another app runs perfectly ok. Many thanks.

Answer 1

I could not find anywhere that I had used Integer.valueOf. In the end I just created a new Eclipse project and copied the files over. That fixed whatever the issue was.

If you have a similar issue and don't know what to do then try that! :P

Sorry I cannot be of more help!
