Question

I am trying to update the Screen on a event Call back in blackberry application. In the Call back I have written a custom Manager. First I am adding stuff to Screen ie manager when loaded(ie in screen’s constructor). Once it is added after some duration I get a callback in which I delete all the fields on the screen and try to add new stuff. Although the deleteAll is working but I am unable to add the new content. I am using below code.

synchronized (UiApplication.getEventLock()) {
        manager.deleteAll();
        RichTextField rich1 = new RichTextField("RichTextField1");
        add(rich1);                
    }

Also tried call to invalidate but no use.

Thanks,

I would suggest another way:

try to do insert then delete like:

synchronized (UiApplication.getEventLock()) 
    {
        RichTextField rich1 = new RichTextField("RichTextField1");
        manager.insert(rich1,0);   
        manager.deleteAll();    
               or
        manager.delete(field_to_delete);         
    }

Hope it helps.
