Hi, I am not sure whether following problem is a design decision or an issue.

Let's assume we have this DB Structure:
{
users: {... /* a node with many users here, having their id as index / ...},
messages: {... / same as users */ ...
}

whenever I call a transaction on a root-node reference and try to access the child "users", I receive a a node with 0 children. However, I'd like to have access to all children from users.

`DatabaseReference transactionReference = FirebaseDatabase.getInstance().getReference().getRoot().runTransaction(new Transaction.Handler() {

@override
public Transaction.Result doTransaction(MutableData currentData) {
MutableData mutableUsersNode = currentData.child("users");
//mutableUsersNode.getChildrenCount() would return 0 when in fact it is more
}
});
`

I can , however, access the children of any Mutable node when it is not one of the root leafs (here users and messages).
Am I doing something wrong here?

What's the best solution to run an atomic transaction on a top-level node?

best regards
