Apart from > that, Thought so, but since object is created in realize routinte itself (and not in any of its callers), did the object destruction in unrealize to be symmetrical :) Regards, Bharata.

I think it is a good pratice to unparent/free the object in the same file it was allocated. Thanks, C.
