I'm opening a sheet on a window , the first time the sheet opens correctly, but if I close it, and try to open again it doesn't work, I just get the system alert sound.
- (IBAction) showSpeedSheet:(id)sender
{
 [NSApp beginSheet:addEditPackagePanel
    modalForWindow:[[NSApp delegate] window]
  modalDelegate:nil
    didEndSelector:nil
    contextInfo:nil];
}
-(IBAction)endSpeedSheet:(id)sender
{
 [NSApp endSheet:addEditPackagePanel];
 [addEditPackagePanel orderOut:sender];
}
I can't find what's wrong, the app doesn't print any error on the log.
