Tree Component Selected Path Value

Try this:

Script
def transform(self, value, quality, timestamp):
	indexes = value.selection.split('/')
	itemPath = []
	currentItems = value.items
	for i in indexes:
		i = int(i)
		itemPath.append(currentItems[i].label)
		currentItems = currentItems[i].items
	return '/'.join(itemPath)

One of the Python guys should be able to reduce this to a couple of lines but this should give you something to work with in the meantime.
