There has to be some other event that is always fired regardless of the
number of items in the list that I can latch onto.

Any ideas?

when only one item in list...


William,

   The reason the example doesn't work is because a replication
manager is only created when the datapath points to 2 or more nodes.
Since there is no replication manager, no onclones event is ever fired.

   A potential work around is to initially point the datapath  to 2
or more nodes, and then switch it to the 'real' dataset.
