There is sessioncloser servlet that gets notified AFTER client is closed so that the server can clean up session data.
We would like to have a hook before the client is closed, to inform the user that there might be unsaved changes and if required veto the close action.
Hope this is possible in all scenarios (applet/webstart/standalone). Maybe the server roundtrip in this moment can be avoided, we could post the user message into the client in a previous roundtrip.
We ony see a chance doing this in case the application was started in webstart mode (or application mode...).
In this scenario we will add the feature to ask the user if the client really should be solved. Similar popup to when clsing Eclipse... (you may have switched off this feature...).

PS: If started in applet mode then you need to add corresponding JavaScript around the applet-tag.
