PRC returns same FolderID as ParentFolderID in simple test

Question

Greetings,
I have been trying to learn the PRC API and encountered an interesting artifact. Basically I get the same FolderID as ParentFolderID for community objects when I invoke a query.
Now, I might be dumb, but I am using the very code out of Plumtree's tutorial on "Extending Server Functionality with Remote API's" so I find it unlikely I copy and pasted wrong.
Interested in knowing if anyone has any insight into this or if this is a Plumtree Bug.
To duplicate just write a little client program:
1. initiate a session with the portal,
2. Retrieve object manager
3. Query the community objects
4. Display portal object properties (For this you have to add folderID yourself.)
Please, Please let me know what you find.
This is G6 , running C#.
Thanks,
Richard

Greetings All,
For your review is the code in which I am noticing the problem. This is code from a Visual Studio.NET project I created. To compile, you must first bind in your IDK references.
