I'm not an expert ... use that response with care ...
I'm using quite a lot of inheritance in my models. Here is how I do it : Define a primary key called id on the root class of the inheritance tree (an attribute with the <<identifier>> stereotype). Dont define other identifier in the tree. Mark all the classes in the tree as <<entity>>. There's no major problem if the root class is never instanciated but marked as an <<entity>>. I actually have abstract root classes in a few cases. As attributes are inherited from the base class, you should not redefine an <<identifier>> on a child class. Hope it helps ... _________________________________________________________ Reply to the post : http://galaxy.andromda.org/forum/viewtopic.php?p=983#983 Posting to http://forum.andromda.org/ is preferred over posting to the mailing list! ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
