Default Updating UI from a callback method

Please Login to Remove!

Hi,

I have a mainscreen that I push using the current UiApplication appearing on the screen.

UiApplication.getUiApplication().pushScreen(myScre en);

I register a listener to an object present in myScreen. When the listener calls the callback method, i want to update myScreen with new fields.

I learnt that the thread where the callback method is being executed is not the eventDispatchThread using the UiApplication.isEventDispatchThread(). I tried doing as follows but get an IllegalStateException:

UiApplication.getUiApplication().invokeLater(new Runnable()
{
public void run()
{
// Add new fields to the mainscreen already pushed.
myscreen.invalidateLayout();
}
});

Can someone please help me understand what I am doing incorrectly?

thanks.

Default

I figured out the reason that I was calling invokeLater on non-eventThread and so it was throwing the IllegalAccessException.

Thanks.
