This is accomplished by the field editor.

Do you have a custom formatter or a binding set up on the matrix that might cause validation to fail and the field editor to refuse to resign first responder status? To see if it's the field editor refusing to resign first responder, return a custom NSTextView subclass from -windowWillReturnFieldEditor:toObject: that simply overrides -resignFirstResponder to call through to super, and break on that return statement to see if the field editor's implementation is returning NO. --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
