Lets say we have some nested resources:
A
--B (child of A)
--C (child of A)
----D (child of C)
----E (child of C)
Each resource has a TV with a value (in this case, an image)
The TV is set for resource A.
The childs D and E) shall now use the image of A if the TV for
A is set
C is not set
D and E is not set.
If C does have the TV set then
D and E should use that value.
If the TV is set for D it uses its own value.
Any idea how to do that elegantly?
