Instead of | @DataModel(value="list1") | private List<String> list1; | | @DataModelSelection(value="focusList1") | private String focusList1; use | @DataModel(value="list1") | private List<String> list1; | | @DataModelSelection(value="list1") | private String focusList1; so appropriate @DataModel and @DataModelSelection have same value parameter. You can also use @Factory to populate list1 when it's empty. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4084823#...
