I altered the script to recursively check property bindings.  
So if property1 is bound to property2, and property2 is bound to a tag, calling the script for property1 will return the tag path on property2.

```auto
# --------------------------------------------------------------------------
# Get the path of the tag that a component's property is bound to.
# --------------------------------------------------------------------------
def getTagForProperty(component, property="value"):
	# Get the window for this component
	window = component
	while window != None and not window.class.simpleName in ("FPMIWindow", "VisionTemplate"):
		# Keep checking the parent until we find a window (or template)
		window = window.parent
		
	if window != None:		
		# Get the binding adapter on the window for the given component and property.
		ic = window.getInteractionController()
		adapter = ic.getPropertyAdapter(component, property)
		
		if adapter != None:
			# Simple Tag Binding
			if adapter.class.simpleName == "SimpleBoundTagAdapter":
				return adapter.getTagPathString()
			# Indirect Tag Binding
			elif adapter.class.simpleName == "IndirectTagBindingAdapter":
				# Parse the indirect tag path
				interactions = adapter.getInteractions()
				ss = [] # List of parts of the string that will be returned
				for p in adapter.getPathParts():
					idx = p.getRefIdx()
					if idx > 0:
						# Get the current value of indirect bindings
						ss.append(interactions[idx - 1].getQValue().value)
					else:
						# Get static strings
						ss.append(p.getString())
				return "".join(ss)
			# Property Binding
			elif adapter.class.simpleName == "SimpleBoundPropertyAdapter":
				interaction = adapter.getInteraction()
				# Recursively check if source property is bound to a tag
				return getTagForProperty(interaction.getSource(), interaction.getSourceProperty())
		
	# Return None if no tag binding was found
	return None

```
