NullPointerException when closing WW applet

[jgoldberg]

Hello!

When running the 9254 2009-03-06 Daily WW build as an applet, I get a NullPointerException when closing WW. The stack trace is:

Sep 2, 2009 11:21:49 AM gov.nasa.worldwind.WorldWindowGLAutoDraw able display

The offending line of code is "this.dialog.dispose();" in the dispose method in DashboardController.java. It seems that this.dialog is null when dispose is called. I went ahead and wrapped the line in if(this.dialog != null). This seemed to fix the problem. Is this an actual WW bug, or is it likely that I'm doing something wrong somewhere else?

Cheers,

Jeremy

Thanks for reporting it. The fix will be in the 1/28 release. The repaired class is attached in case you need it now.
