[quote author="OverZealous.com" date="1244420384"]I don't think the error is not being caused by the two lines. When you comment them out, the $save below them just doesn't attempt to save the Category. The error message explicitly mentions Article, so the error is most likely related to Article.
Do you have a controller that is also named Article?? You cannot have controllers with the same name as your Models (otherwise one class will override the other).[/quote]
You're right on the ball Phil, just updated my post to say I had called the controller the same name as the class :p
