osx - NSWindowController orderOut crashes in Mac Yosemite 10.10 -

the next code worked mavericks (10.9), 1 time upgraded yosemite 10.10 crashes. best way overcome sheets over-outs?

my class holds member:

emailclientwindowcontroller* emailclientsheet;

(while emailclientwindowcontroller : nswindowcontroller)

upon button click nowadays window modal sheet:

self.emailclientsheet = [[emailclientwindowcontroller alloc] initwithdocument:document]; [nsapp beginsheet:self.emailclientsheet.window modalforwindow:self.view.window modaldelegate:self didendselector:@selector(didendsheet:returncode:contextinfo:) contextinfo:nil];

and didendsheet method following:

- (void)didendsheet:(nswindow *)sheet returncode:(nsinteger)returncode contextinfo:(void *)contextinfo { self.emailclientsheet = nil; [sheet orderout:self]; }

but, line [sheet orderout:self] crashing in yosemite! , code has been working several years now! best way overcome issue?

thanks!

solution replace order of nil assignment , orderout. meaning:

- (void)didendsheet:(nswindow *)sheet returncode:(nsinteger)returncode contextinfo:(void *)contextinfo { [sheet orderout:self]; self.emailclientsheet = nil; }

still didn't figure out apple changed in osx 10.10 in comparing 10.9, memory optimizations. didn't find related clues in 10.10 release notes nor in blogs. anyhow code improve releasing windows.
