Adding a Web Dynpro Model on a Composite Apllication Component in CE 7.1

Hi experts,

I am trying to add a web dynpro model to a Composite Application DC.

I am using SAP NW CE 7.1.

In CE 7.0, this was done by simple right click on the CA DC.

but i am not able to do it in CE 7.1.

Can somebody tell me how do i add a web dynpro model to a composite application DC???

basically i need to add a UI corresponding to a composite application?????

Cheers
