Rim,
On the surface of this I would say you need to use the modified() 
function on the polydata that you deleted the point from. This will 
cause the updated data to drive the pipeline again when the scene is 
rendered. Also, the point is represented in one or more cells by ID, you 
may have some errors with invalid structures based on th emodified 
points. Post an example for discussion to get some meaningful results.

Hope that helps,
Jim
