Sounds like you are calling UiApplication.popscreen() from some context other than the UI Event thread.

Can you post a code snippet?

thanks for ur sincere reply..i get exception while am calling this code:

  UiApplication.getUiApplication().invokeLater(new Runnable() {
                  public void run()
                  {
                      UiApplication.getUiApplication().popScreen(pop2);
                  }
              });

even if i try implementing this code am getting the same exception

UiApplication.getUiApplication().invokeLater(new Runnable() {
                  public void run()
                  {
                         UiEngine ui = Ui.getUiEngine();
                         ui.popScreen(pop2);     
                  }
              });

where do you call this code? i would also guess that it is in the wrong context, for example from a listener that is called by a class without ui.

yeah.this method was inside my phonelistener and i call this through popscreen which is the activescreen displayed...am trying to close another popscreen in my app which is just lies beyond the default screen appears when call is in progress...
