[jboss-user] [EJB 3.0] - Re: ejb3 - setList(Set<MyObjs> list) - fails to persist.

Hi ! I will try to help: Q1: If you need only one cascade type value you use the single item notation: cascade=CascadeType.ALL You can OR the casace type values: The following sample will cascade any operation beside a delete (and here you will need the array notation): cascade={CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH} Q2: I think you don't need to initialize the relationship field with a value. Set it to null, the container will do the rest. When you create relationship items you should update both sides of the relationship. Something like: myObject.getOwnedItems.add(unsavedNewOwnedItem); | unsavedNewOwnedItem.setObject (myObject); Hope this helps Wolfgang View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4027271#...
