Mike,
Thanks for answering.
I never directly call that. Though I call plain-old commitEditing in about 100 different places.
Further searching found one similar report:
<http://www.cocoabuilder.com/archive/cocoa/284791-nsinvocation-error-when-closing-dirty-document.html?q=[NSInvocation+invocationWithMethodSignature:]:+method+signature+argument+cannot+be+nil#284791>
Which gave enough clues to repro the issue. It seems like an OS bug, since it repros only in 10.6 and not 10.7 or 10.8. (For us, it happens when there a text field that has focus but is empty, then a long computation is started, then the user presses Cmd-S.)
Cheers,
Sean
