hello, does someone know a way to handle deletes of entities which are part of a manytomany relationship. especially when cascading deletes.
I have two entity classes A and B. A references a set of B, and B references a set of A. deletes on B should be cascaded to all As referenced by B. Is there a way to have the entitymanager cascade deletes on A to B only if there are no more As dependent on B? The only way I know to do this, is to check the state of the relationship before removal myself. The problem is, that this logic would be outside the entitybean, since there is a entitymanager needed to delete Bs, which are no longer in use by other As. Of course I could create a entitybean method which would require the entitymanager as parameter, but i think, i hope there is a better way, i'm not aware of. Any comments on this topic are welcome. thanx in advance, milan wölke View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3926108#3926108 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3926108 ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
