Hi,

My question is going to this:

Can different entity kinds be part of a group?

I have blog Items, and each Item can have Comments (which have a ReferenceProperty to the 'parent' Item).

I want to delete an Item and all its Comments, so I thought an entity group would be good to run in a transaction, otherwise if there was a problem, I could be left with orphaned Comments (without an Item), or an Item with missing Comments.

As I experiment with this, I'm not getting the entity group membership set or acknowledged, and when I try the transaction, I get an error. I fear that only entities of one kind can belong to a group, but what's the good of that in my case, and how do I do my transaction with safety otherwise?

Any ideas?

Thanks!

Thanks Dave!
