Hi Shaneela,

Where exactly you're adding this? If you're inside any of the policy methods, you can do something like:

Ptr<Node> n = item->payload ()->GetContentStore()->template GetObject<Node>();

Note that there is "template" keyword before GetObject.  Is is necessary, since policy and all policy methods are part of the template implementation.
