I am trying to extend the Benefit Catalog Add and Edit with an additional tab. I am able to get the Add to work but when I create the Edit and add the similar code for the DataFormExtension, the new tab is not displayed. The difference is the DataFormInstaceID is for the Edit Benefit Catalog.
<c:DataFormExtension DataFormInstanceID="096cb416-35e2-4067-866a-b321676a1711" RenderStyle="Tab" TabCaption="Critieria"/>
