Hi Peter, In order to make the collection itself nillable you'd need to add a wrapper element for the collection (such as by using name="CategoryLists" on the <collection> element). That would give you a way of saying the collection is not present in the XML representation. As it is now, you really should get an error for the nillable="true" attribute on the <collection> (since there's no element matching the collection itself, and nillable="true" can only be used in conjunction with an element).
If the XML is being generated outside your control, the best I can suggest is that you add a set-method for the collection and inside this set-method check for the case where the only thing present is a null. If that's the case, rather than storing the passed-in collection you'd just set the value null. - Dennis Dennis M.
