the entityData methods are just for convenience. As you have a special use 
case, I recommend that you override ::data instead.

You can then get the Item and ParentCollection from the index parameter 
passed into that. The ParentCollectionRole should give you the parent 
Collection whether it's virtual or not.

All the best,

Steve.
