[vtkusers] How to change the actor data without deleting it.

[Ahmad Hosseinzadeh]

Hi,

I want to change the actor data (e.g. add/remove a
filer to/from actor) without removing the previous
actor and create a new one.
I have disconnected the actor from renderer before
setting the mapper but it dosen't work. The
application halts when I want to connect data to actor
using "setMapper()" method.

Do you have idea how to figure it out?

Thanks,
ahmad.
