Thanks Igor, It seems like maybe WICKET-2026 is also related: http://issues.apache.org/jira/browse/WICKET-2026 This changes how Form#anyFormComponentError handles border components, it looks like, but also switches us to a FormComponent visitor.
Will it be helpful if I create a new JIRA issue? RUSSELL E.
