rich:extendedDataTable columnsOrder attribute is not working
------------------------------------------------------------

                 Key: RF-11776
                 URL: https://issues.jboss.org/browse/RF-11776
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-tables
    Affects Versions: 4.0.0.Final
         Environment: Websphere AS 8, MyFaces
            Reporter: Dmitry Volkov


I am not sure if columnsOrder attribute may be used or it is deprecated, but there is definitely an error in SortingFilteringRowsRenderer.updateAttribute method. 
This line: 
{code:java} 
component.getAttributes().put(attribute, null);
{code}
always throws NullPointerException which is shallowed by try .. finally in UIDataAdaptor.visitTree method.
