Brian Leathem updated RF-11806:
-------------------------------

    Fix Version/s: 4.1.1.Final
      Description: 
The fix introduced for 4.1.0.CR1 by adding event registration to the constructor:

{code}
public UIDataAdaptor() {
        super();
        getFacesContext().getViewRoot().subscribeToViewEvent(PreRenderViewEvent.class, this);
    }
{code}

breaks when Spring Webflow restores the view in the middle of the flow with a NPE. E.g. when a data table is constructed, the viewRoot is not yet set on the current thread, which causes the exception above. 



  was:
The fix introduced for 4.1.0.CR2 by adding event registration to the constructor:

{code}
public UIDataAdaptor() {
        super();
        getFacesContext().getViewRoot().subscribeToViewEvent(PreRenderViewEvent.class, this);
    }
{code}

breaks when Spring Webflow restores the view in the middle of the flow with a NPE. E.g. when a data table is constructed, the viewRoot is not yet set on the current thread, which causes the exception above.
