Hi, I have the following code to run a save panel:
NSSavePanel *sp = [NSSavePanel savePanel];
[sp setExtensionHidden:NO];
[sp setTitle:NSLocalizedString(@"Export image to PNG file", @"")];
[sp setRequiredFileType:@"png"];
[sp setAccessoryView:bitmapAccessoryView];
[sp beginSheetModalForWindow:[document windowForSheet]
completionHandler:^(NSInteger result) {
if (result == NSOKButton) {
[self exportBitmapToFile:[[sp URL] path]
usingBitmapImageType:NSPNGFileType];
}
[self cleanupFromExportOfType:exportType];
}];
When running on Lion, some users are getting the following exception:
parentForItemsInColumn: is not supported for browsers with matrix delegates
The trace is as follows:

I am unable to reproduce the problem here, but have had the problem reported by
several people running Lion.
Is there something I am doing wrong in my code? Could this be a Lion bug?
Thanks
Gideon
