porting PreferencePane to Lion [NSTextField getCString:maxLength:encoding:]: problem

Question

I have a PreferencePane that works on Snow Leopard and we are getting ready for Lion. PreferencePane fails to load and gives me the following error in the Console. Note that it refers to 3 NSTextField instances (reports the same error twice per NSTextField).

I have way more than three NSTextFields in the preference pane. This happens after initWithBundle: completes successfully but before mainViewDidLoad.

Answer 1

Problem solved.

Issue was that I had an NSTextField with variable name 'identifier'; while 10.6 didn't have any problem with it, 10.7 does. From some reason XCode on Lion didn't even warn me about it...
