There...
I created a new project with just the code I need (didn't want to bother you with all of the code)
So what would I need to do to push the screen (if it's not already displayed)
Whatever I try, I always end up with a illegalstate exception :(
Code:
class TestPushScreen extends net.rim.device.api.ui.UiApplication
{
public static void main(String[] args)
{
if(args != null && args.length > 0 && args[0].equals("gui"))
{
TestPushScreen instance = new TestPushScreen();
instance.enterEventDispatcher();
}
else
{
mBackgroundThread = new BackgroundThread();
if(mBackgroundThread == null)
{
//impossible to create thread... so exit
System.exit(-1);
}
else
{
try
{
Thread.sleep(2000);
mBackgroundThread.start();
}
catch(Throwable ie)
{
}
}
}
}
TestPushScreen()
{
mMainMenu = MainMenu.createMainMenuInstance();
pushScreen(mMainMenu);
}
public static MainMenu mMainMenu;
public static BackgroundThread mBackgroundThread;

Mmmm...
I was able to get the instance of my app and then call the pushScreen...
no error but the screen isn't displayed.
when the app tries to push it again after 5 seconds, I get a runtime error saying the screen is already pushed...
If it IS pushed, how come I don't seen it?
-- edit
I was able to display the screen.
I forgot to call "requestforeground"
Now, the problem is that after the screen is displayed, the thread stops running.
So it doesn't check for futur calls of pushscreen...
I want the thread to still run in the background, even if the screen is already displayed.
It WILL result into a runtime error, but I don't mind.. I just catch it and do nothing with it..
any ideas?
PushScreen from background thread
