I experienced an issue when using an awt FileDialog on Mac OS with Webstart. When you open the FileDialog, the tree on the left will not be fully loaded. Same thing with the center file view. And when you do a single click within the center view, the UI somehow refreshes and the tree on the left and the center file view will display all contents correctly. When you double click a directory the file view shows no files. After one click within the center view, the center view refreshes again and everything is visible. This happens on all file view types of the mac os representation of the file dialog. Everything works fine if I start the application without web start. I have set security -> all permissions in jnlp file. Is there anything special I could have missed or is this a bug?
We are also experiencing an issue with awt File dialogs with Webstart Java 1.7.0_07-b10. In our case the dialog just hangs trying to refresh with a busy "spinner". The problem does not occur when running the same app from the command line (i.e. not with JWS).
