Hi guys,

I'm trying to use a JList in a window, and getting a class cast exception.  The list is initialized using the default constructor (via Class.newInstance()).

Here is the stack:


java.lang.ClassCastException
       at com.xith3d.userinterface.UIWindow.getDirtyAreas(UIWindow.java)
       at com.xith3d.userinterface.UIWindow.getDirtyAreas(UIWindow.java)
       at com.xith3d.userinterface.UIWindow.renderToBuffer(UIWindow.java)
       at com.xith3d.userinterface.UIWindow.update(UIWindow.java)
       at com.xith3d.userinterface.UIWindowManager.newFrame(UIWindowManager.java)
       at com.xith3d.scenegraph.View.getRenderFrame(View.java)
       at com.xith3d.scenegraph.View.renderOnce(View.java)
       at com.xith3d.scenegraph.View.renderOnce(View.java)
       at com.riverside.ch.client.CHClient$1.run(CHClient.java:88)






I think the problem lies inside getDirtyRegions()here:          
1  
2  
3  
4  
5  
6  
7  
        if (c instanceof Container) {
            Container ca = (Container) c;
            Component cs[] = ca.getComponents();
            for (int i = 0; i < cs.length; i++) {
                getDirtyAreas(p, (JComponent)cs[i], areas);
            }
        }


What do you think?  Can you try replicating this by adding a JList that has no model?

Have a good one,

Eric

It may look complicated, but in the end it is just a bunch of triangles

Sweet.  Thanks.  Was it the converting between Components and JComponents?
