Description
Classes which implement the java.util.Collection interface are not properly XML encoded.
An example of this is BeanContextSupport (which implements BeanContent which is a sub-interface
of Collection).

It's important to support the XML encoding/decoding of BeanContext classes since they are part
of the Java API.

WORK AROUND Should write a user settable persistence delegate.
11-06-2004
EVALUATION Part of the problem is that there is no clear method to get/set the group of objects managed by the Collection. The add/addAll/clear/remove/removeAll are optional operations. Which mean that it's not required. In fact, for BeanContextSupport, the addAll, removeAll and clear methods throws an UnsupportedOperationException. Perhaps a persistence delegate to support generic Collections is not feasable. The solution for this could be to write a PersistenceDelegate for BeanContextSupport that uses the methods: Object[] toArray() for retrieval and void add(Object) to set. ###@###.### 2002-03-14 A persistence delegate for java.util.Collection was created and put into MetaData. There is also a BeanContextSupport persitence delegate which will also support the persistence of BeanContextServicesSupport as well. ###@###.### 2002-04-22
