Bug 286

Summary:	Window looses focus
Product:	UPPAAL	Reporter:	Gerd Behrmann <behrmann>

Description Gerd Behrmann 2006-03-07 16:52:09 CET

When rapidly and repeatedly clicking on the check button in the verifier on an empty query, the GUI tends to loose focus in such a way that it can still receive mouse events, but any keyboard events are not directed at the GUI. The window frame indicates that the windows is not selected. Clicking on the window does not give it focus.

If the problem occurs, the only way to recover normal behaviour is to restart UPPAAL.

It is unclear if this is our fault or a bug in Swing.

Alexandre, could you please take a look at this. This is the problem we talked about some days ago.

Seems to be bug 6265294 in Java 5 (see Sun's bug database). Apparently this has been fixed as a side effect of the fix for bug 4080029 in Mustang (Java 6) release b38.

We have implemented a work around for the issue by introducing a 100ms delay for the verification dialog. This is not noticable by the average user.
