Hi.

I have a utility that is successfully triggered by a NodeEventCallback.  I want to be able to toggle this utility on/off - but can find no description of how to remove a NodeEventCallback. The remove syntax for regular callbacks doesn’t seem to work and I have to use the NodeEventCallback as my utility is related to a sub-object selection change.

any help much appreciated!

So in the end I got the answer from a contact who is part of the AutoDesk developer network. For the benefit of anyone else who is encountering this, here’s the explanation:

When you call NodeEventCallback, you are creating an instance of the class.
myInstance = NodeEventCallback(—arguments here );

To release this, we need to delete the class.
myInstance = undefined;—remove handle to class
gc() —force memory reclamation to actually delete anything

The guys at ADN agreed this was unintuitive and promised to add it to the help documentation.

Thanks for solving this, there was a similar thread at cgsociety, http://forums.cgsociety.org/showthread.php?f=98&t=725434
