Question about NSResponder cancelOperation

Subject: Question about NSResponder cancelOperation
From: Iain Delaney <email@hidden>
Date: Fri, 23 Feb 2007 22:43:35 -0500

Hello, I've got a window with two NSTextFields on it. I want the user to be able to cancel editing in either of the text fields, but I need different behaviour depending on which field is active when the user hits Esc. My controller class implements cancelOperation, so I'd like to determine which text field send the message by examining the sender argument. The problem is that the sender argument is nil, according to NSLog and gdb. Does anyone know what's going on here?

Thanks,

Iain Delaney
