java.lang.IllegalStateException: not in swing thread! - invokeAndWait not workin

Troubleshooting General Help
1

Hey,



i try to create a new jmedesktop, in an the actionlistener of a button.

I get the following exception: java.lang.IllegalStateException: not in swing thread!

I was looking about it in other threads, and i found that i shall use the invokeAndWait method.

so i tried:


   SwingUtilities.invokeAndWait(
         new Runnable() {
         public void run() {
                   MenuState_Main main = new MenuState_Main()
                }
    } );



But then I get the following exception

i'm confused - what is the corret way to do that?

but unfortunately it is not  :frowning: :frowning: :frowning:



first I'm creating all the menu from my main class…  - the swing stuff is than injected into the swing thread by the jmedesktopstate…

so the next time i want to create a new menu, the actionPerformed is executed in the swing thread - is this correct or am i wrong… and there i got the problem, beacause there I'm getting the java.lang.reflect.InvocationTargetException except. and when I'm starting a new thread in the jme thread for creating the gamestate i get "not in swing thread" even when i m using SwingUtilities.invokeAndWait(



I don't get it…



:x

You should check if you are in the swing Event Dispatch Thread before calling invokeAndWait(), then only call it if you are not in the EVT. http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/SwingUtilities.html#isEventDispatchThread()

Seems like the code that you call from invokeAndWait does another invokeAndWait, which is not allowed, since it would cause a deadlock.

thx for your answer…



now i'm trying it form another thread…

there i don't get the InvocationTargetException, but again the not in swingthread exception, even when I'm using  SwingUtilities.invokeAndWait  :? :? :? :? :? :?



i have no idea why

again:



this is my code now


class GameStateLoader extends Thread{
      
      public GameStateLoader(){
         
      }
      public void run(){
         //GameStateManager.getInstance().detachAllChildren();
         try {
            SwingUtilities.invokeAndWait(
                  new Runnable() {
                     public void run() {
                        MenuState_Main main = new MenuState_Main(CoreGame.JMEDesktop_Main,parentGame,coreGame);/                        
                     }
                  }
            );
         } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
         } catch (InvocationTargetException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
         }
         MenuState_Main main = new MenuState_Main(CoreGame.JMEDesktop_Main,parentGame,coreGame);
      }
   }



I'm starting this thread out of the action performed method of another gui..... and  I'm still getting "not in swing thread"

:x

Well you do it both ways in that one… on should go wrong at least right?
