Description
A test page for ace:listControl inside icecore:repeat was added to the listControl QA test app:
http://dev.icesoft.com/svn/repo/qa/trunk/Regression-Icefaces4/Sparkle/Nightly/listControl
Test page: /listControlIcecoreRepeat.jsf
When moving a list item using the listControl buttons, the moved items disappear instead of being rendered in the next list.
A javax.el.PropertyNotFoundException occurs when submitting the form after moving items from one list to the other. In other instances, a NullPointerException occurs with the same steps.
This may be as well a test app issue; the listControl inside ui:repeat works fine.

This exception occurs only with ace:listControl because the component invokes UIViewRoot.visitTree which causes the Repeat.visitTree to re-enter and rewrite the row index and var instance.
