There is also another feature request on collections where it uses any preconstructed collection rather than creating a new one. http://jira.jboss.com/jira/browse/JBMICROCONT-35 | public class MyClass | { | private List<String> list; | | public List<String> getList(); | } | | <property name="list"><list><value>...</value><list></property> | i.e. this will do getList() and if it is not null, it will add to the list rather than overwriting it.
