I don't understand what this means.  It sounds like you're saying you 
have to have CustomerRestService be a leaf resource.  You don't have to. 
If you don't want it to be a leaf resource, don't make it a leaf 
resource.  The way you not making it a leaf resource is by not setting 
`isLeaf = True` on it.

I still don't understand the problem you're having.  As I said, 
regarding the "solution" I gave in my previous email, it's just how you 
would achieve the behavior I thought maybe you were trying to describe 
wanting, but I don't really understand what you're trying to accomplish 
or why.
