You could try overriding setValue:forUndefinedKey: (see NSKeyValueCoding Protocol Reference) in your Action class and set a breakpoint there to determine the stack trace for the error. Additionally, if no other solution can be found overriding this method and leaving it empty will prevent it from throwing said error from it's default implementation, and you can handle the error in your own way. - Stefan _______________________________________________ Cocoa-dev mailing list ([email protected]) Please do not post admin requests or moderator comments to the list.
