Hi, I got the same error. If I put just @In(create = true) | UserHome lastUpdatedBy; I get an exception about not-null value for that component (when some other's component list is called - a component reffering the first one) If I put @In(required = false, create = true) | UserHome lastUpdatedBy; I get an exception latter when I try to "add" a new object. More specific in the wire() method lastUpdatedBy is null and I get a NullPointerException. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040582#...
