Description

Per JPA spec we should support mapping to-many relationships as Lists, Collections, Sets and Maps (we currently only do Lists). Need to add that stuff to Cayenne classic and map to JPA. I see the following subtasks:

• Support explicit to-many semantics mapping in ObjRelationship (collection class; map key for Maps)
• In the Modeler allow to specify the choices in ObjRelationship Inspector
• In class generation template use correct collection type (I guess for maps the add/remove semantics can be the same as for lists ... not sure if we need removeFrom(Object key)??)
• Runtime support, including reverse relationships
• Support for prefetching
• Testing
• Bridging JPA mapping
