Getting Request Object KM Repository framework

Hello All,

We're trying to build a Shopping Cart component in Portal(EP6 SP2). The cart object is being stored in the Request Session, but we're having problems getting hold of the Request Session in KM Repository framework.

We are relying on "KM Property Filters" to dynamically check the shopping cart (from session) and display properties accordingly. If a resource exists in Shopping Cart, then we need to display "Remove" button, otherwise display the "Add" button. But, the KM Property filter does not have access to the Request Object in order to get the Shopping Cart from the Session.

Any Help on Suggestions on this issue would be much appreciated.

Thanks.

Harman
