Are you sure that it's not Chameleon or the widget that's caching the 
numlayers value?  (Bart's problem seems to be with numlayers, not 
numclasses BTW)

I seem to remember a problem related to that in PHP MapScript but it 
would have been fixed a long time ago (back in 2002 according to CVS 
logs). I just checked in the 4.2 source and the $layer->numclasses is 
synchronized after creating a new class. Same with the $map->numlayers 
when adding a new layer.
