If a node extension has a list and a datachange is registered on the node extension then onDataChange gets the child list and not the node extension

Hi,
I created a node extension to use a group that contains a list.

When I registered for dataChangeListener using the Node Extension and then look at what nodes I get in the onDataChanged call back, I get the list node and not the extension node.
If I remove the list, then I get a node from which I can get to the node extension.
I have created a gerrit change with sample files. I will upload the gerrit the id to this bug soon.
