the issue i mentioned in this post is actually happening because of cross threading GUI issues (i hope).

could you help me with Java version of action delegate please?

in C# it is done as this inline:

        this.Invoke(new Action(delegate()
        {...}));

how is this achived in Java?

thank you.

public class processChatMessage implements Observer {

    public void update(Observable o, Object obj) {


        System.out.println("class class class" + obj.getClass());

        if (obj instanceof String){

            String msg = (String)obj;

            formatChatHeader(chatHeader.Away, msg);

            jlStatusBar.setText("Message Received");

            // Show chat form
            setVisibility();

        }
    }
}

processChatMessage is invoked by a separate thread triggered by receiving new data from a remote node.

and i think the error is being produced as it trying to update GUI controls.

do you think this is the reason? i ask because im new to Java and C#, but this is what is going on i think.
