What _should_ be the behavior of inherit="true"?
a) Only inherit values from ancestor nodes when node data does not

Thanks for the feedback. I've tested it again and you're right:
When I clear out the values in a field of a dialog and then save
the dialog, the corresponding node data gets deleted too.... and
inheritance works again afterwards. I don't know how I ended up
with an empty node data this morning. So forget my post. Option a)
works perfectly fine.
What about when inheriting a collection? I have a case where I
inherit using the contentNodeIterator tag and if I add content to
page and later delete it then it leaves an empty node in the
hierarchy. At this point the only way to get inherit to work again
is to go into the JCR browser and remove that node. I thought about
changing the behavior of the tag to deal with this but also wonder
if the empty node should be deleted when the collection no longer
has any paragraphs...
Yes, this happened to me to. Here's an idea for a workaround (i.e.
ugly hacks) for this problem:
- Check the length of the collection _before_ the contentNodeIterator
tag.
- I the length is zero, delete the contentNode by scriptlet.
As I said: ugly hack! But it should work since this "cleanup script"
will be called when you delete the last item (paragraph) in the
content node iterator.
