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.
