Modal dialogs not supported yet?

[Andreas Hoeschler]

Hi all,

I run a modal dialog as follows.

   if ([NSApp runModalForWindow:panel] == NSRunStoppedResponse)
        {
        ...
        }

When I click on the cancel button in the modal dialog which calls 
[NSApp abortModal] I get a "Abort Modal" exception. I looked into 
NSApplication.m and found

/*
 * Running modal event loops
 */
- (void) abortModal
{
  if (_session == 0)
    {
      [NSException raise: NSAbortModalException
                  format: @"abortModal called while not in a modal session"];
    }
  [NSException raise: NSAbortModalException format: @"abortModal"];
}

This method always raises an exception. Are modal dialogs not supported 
yet? What am I missing?

Thanks,

   Andreas
