Well, it looks like the same error, andwith the same cause of a property not set in the catalogBean. But, this most certainly won\'t have the same origin. The problem Carsten had was because of a missing feature in the Concoon JSR-168 container. In your case, you must have modied more than you wanted in the SearchProducts.jsp (and possibly elsewhere). Just changing the table title would have no side-effect. I suggest you compare all your code with subversion and carefully check all the differences.
