Views passed into functions do not update properly

[Jean C. Marshall]

Gang:
We have run into a problem in which passing views into a function causes 
the updaters to not be called. Here is an example.
John and Jean

        //======================================================================
        // Function -- QRelations<Traits>::calcEdgeSoundSpeed
        //======================================================================

        template <class Traits>
	void QRelations<Traits>::calcEdgeSoundSpeed ( const 
ScalarField&  EdgeSoundSpeed,
                                                                  const 
ScalarField&  VertSoundSpeed )
        {
                ENTER("QRelations::calcEdgeSoundSpeed");
                
                int d = getEdgeDirection(EdgeSoundSpeed);
                     // Without this explicit update call, the updaters do 
not get called for VertSoundSpeed
                VertSoundSpeed.update();
                EdgeSoundSpeed(CoarseEdges[d]) =
                       min( 
VertSoundSpeed(CoarseEdges[d]),VertSoundSpeed(EdgeNgbr[d]) );
                
        }           // end function calcEdgeSoundSpeed
