Exception at dispose shell [message #134169]

Hello,

I get an java.lang.StackOverflowError when I close my shell. I have the
following code snippet for this close event.

mainShell.addShellListener(new ShellAdapter() {

public void shellClosed(ShellEvent e) {
resultList = null;
mainShell.dispose();
}

public void shellDeactivated(ShellEvent e) {
resultList = null;
mainShell.dispose();
}
});

The error is in methode shellClosed at line mainShell.dispose().
Where is the error in my code?

Thanks,
kristin

Hi Kristin,

just a wild guess: the dispose() method calls the shellClosed() method of the listener, thus you end up in an endless loop.
maybe you could use a simple boolean variable isClosed to avout calling the dispose() method for a second time...

HTH,
ben

Hi Kristin,

The StackOverflowError might be related to this bug:
229309: StackOverflow when widget disposes of its parent while itself in
dispose
https://bugs.eclipse.org/bugs/show_bug.cgi?id=229309

Anyway, there is no use in disposing of the shell on shellClose. Closing
a shell automatically disposes it. So you can safely remove this call.

Regards, Ralf
