I am trying to trigger a python node (should be the same as in SOPs) whenever that particular node is in the tree/branch currently viewed. Using "node.cook(force=True)" does work, but it gives me an error on the node with "Infinite recursion".

Basically, if I have two python nodes that prints the current time, I would like them to print the time whenever they or a node further down in each tree is selected.

Any idea on how to remove this error or another way to do it?
