Hi! Can I have execute some code when I cloned some nodes? I need this to generate new names in components to ensure that there is not duplicated names.

I don't think that core development is the right category for this. You probably want "Creating Nodes".

When you say "cloned", do you mean a copy/paste operation in the Editor on a node instance to create a new copy of an existing node instance?
