[vtkusers] Problem with updating

I've been toying with this problem endlessly, and it seems I'm nowhere
nearer to the solution than when I began. Basically, the rendering program
has an input which changes over time, and that input is plugged into a
vtkProgrammableGlyphFilter which is then plugged into a renderer.

When I initialize the source, everything is fine and dandy, but when I add
elements onto the source (with the same 'old' elements in the source),
they don't get displayed. I suspect that this is something to do with an
UpdateExtent not being right, although I lack experience in this area.
Anyone have any ideas? Thanks in advance
