Is there a way to tell if a component property has a binding assigned to it within a python script? My goal is to iterate through all the components in a view, and refresh the visibility property binding through a property change script. I’ve got it working, but I’m getting errors when it iterates over components that do not have a binding assigned to their visibility property.

call self.refreshBinding(“meta.visible”) if it throws an exception. It doesn’t have one?

Didn’t even cross my mind to use try/except… That works nicely! Thanks for the help!
