You could try to use OVERRIDE:
TerrainState->setAttribute(pTerrainPolygonMode ,
osg::StateAttribute::ON | osg::StateAttribute::OVERRIDE) ;
just to make sure that the pTerrainNode doesnt define these states
further down in the scene.

HI Siddarh,
I don't know where to start, simply don't know enough what is the
problem or your implementation to know whats up.
There is the osgGA::StateSetManipulator that does something very
similar and its works so have a look at it.
