My ExternalApplicationBean IS serializable, it's java.util.RandomAccessSubList that isn't serializable but that's something I can't change I guess.. My ExternalApplicationBean holds a HashMap<String,List>
Please look at the jira issue for MyFaces http://issues.apache.org/jira/browse/TRINIDAD-27 and the line List.subList() does not return a serializable object, because it can return a RandomAccessSubList, which is not serializable.
