Sorry for the typo. It should be a release message in the
savePanelDidEnd method.

Hi,
What happens is that the panel is added to the autoreleasepool and
hence released after a release cycle. What you want to do is to add
a [pan retain] in your saveGraphics method and a retain message in
your savePanelDidEnd method. I think.

Since upgrading to Leopard , I have noticed frequent crashes after
entering a standard Cocoa open or save panel. It even happens in
openDocument: command linked to Open... menu command that is built
into NSApplication and I have not overridden that method. This same
code has worked fine ever since 10.0. It seems worse building to
"Current Mac OS" than to "10.4 (Universal)", but now I am seeing if
in both bulds
For example, this method (a target of a menu command) just crashed
// save graphics to PDF file
- (IBAction)saveGraphics:(id)sender
{
NSSavePanel *pan = [NSSavePanel savePanel];
[pan setRequiredFileType:[self graphicsExtension]];
[pan setTitle:@"Save Graphics"];
[pan beginSheetForDirectory:nil file:nil
modalForWindow:[self window] modalDelegate:self
didEndSelector:@selector(savePanelDidEnd:returnCode:contextInfo:)
contextInfo:nil];
}
The sheet opens, but then crashes before I can interact with it.
Part of crash log is below (full log is too long for this list)
