Resetting JApplet Content Pane

Question

I have an applet which needs to wait on another applet in the page being loaded before the GUI components can be rendered on the screen. My plugin appears to load the applets in the order that the HTML tags appear on the page, which is exactly the wrong order. Therefore, I spawned off a task to check for the other applet and load the component when it is present. According to debug output, all goes well. No exceptions are thrown and no debug output indicates any exceptions or error conditions being triggered. Instead, output indicates the GUI getting built and the content pane getting set to the new Container. Unfortunately, this new content pane never displays. Instead, the applet becomes a never-repainted box. What about JApplet and painting am I missing?

You need to do your modifications to Swing components on the AWT thread after the components have be realized, i.e.
            java.awt.EventQueue.invokeLater(new Runnable() {
                public void run() {
                        ////  make your changes to Swing components here
            });
