I don't use ModelDriven myself, but as I understand it, it places the Model Object at the top of the Value Stack, which would make userid be a reference to an attribute in the Model Object, not in the Action. When you use user.userid, it's because it's trying to find the user attribute in the Model Object (on the top of the Value Stack), which fails so it goes a step down the stack to the Action, where it finds a user attribute to use.
So, it appears Struts is functioning exactly as designed.
