[C++-sig] pointers and pyste

thank you for a wonderful library. I am a c++ newbie trying to write a
ray tracer and making it scriptable in python using boost. I have had a
fair amount of success but I have a question to which the answer was
not entirely clear in the documentation or the faq.
I have a c++ class which stores pointers to a set of c++ objects
//iterate over list blist
// and call the render method on each object.
which I wrapped using pyste. I also wrapped the class B using pyste.
now I initialized a copy of B in python and passed it to add_b to add
it to blist.
so far so good.
The problem starts when I call the render method in A which in turn
calls the render method on each of the classes stored in blist. since I
was using pyste to wrap the class,
the render method being called turned out to be the one associated
with the wrapped object(a subclass of B from what I can gather) and not
the actual class B. This causes problems since there was some
additional funkiness with the way the wrapped method was handling some
references. However putting an explicit exclude statement in the pyste
files to exclude the render method for class B solved the problem.
Is there a problem here ? is this the standard way of doing stuff ? it
seems quite cumbersome to exclude methods like this.
