Activation condition using relying party by group

[Cantor, Scott]

> So, any clues on why it's trying to type cast and fail?

You're omitting part of the actual example. You can't apply the EntityGroupPredicate directly in a place where it's expecting a condition to operate on a ProfileRequestContext.
 
The example in the wiki is complete and it's all needed. You must wrap the function in the parent bean shown, that bean indirects the condition from ProfileRequestContext down to the metadata object you want to test. The syntactic magic it's pulling off is all hidden inside the parent bean.
