I'm looking for a way to propagate parts of node labels up the tree for some types of nodes.
I managed to do this with a custom function which determines the type of node it's operating on and gets the required data from the children elements. This works fine, except the parents' labels are not refreshed when their children elements are changed.
I started fixing this by adding listeners but this seems to be a bit overkill.
Is it possible to access a node's label from the expression in the
parent's label? (And as a bonus, have dependent labels refresh automatically?)
