Max, I believe that your issue lies in the section of the mapping descriptor for the RoleInProject object. I'm seeing that you're using a multi-column primary key. I'm not well versed in multi-column primary keys, but I think I see the problem. The fields in the RoleInproject object are complex objects, not primitives. In the identity attribute of the class element, Castor is told to use the complex objects rather than the primitives in those complexe objects. However, when Castor drills down into those complex objects, it discovers that the id for each of them is, in fact, a primitive (each one is an integer) and throws the exception because, as the error states, setProject is expecting a Project object. I do know that using foreign keys in a multi-column primary key can be very troublesome. Are you designing the database schema from the ground up or did it already exist? I'm not sure if this would work for your situation, but have you considered making use of nested attributes (http://castor.exolab.org/nested-attr.html) instead?
