Description

Insert and Update operations work as expected, but query operations operate on the primary datastore.  I see from stepping through the M1 code that Insert and Update operations use a transaction that accesses a FederatedDataStore.  I guess that is where the difference occurs in that the query operations get a data store another way, failing to get the FederatedDataStore that is configured.

example code created from helloworld-archetype is at https://github.com/bkalbfus/isis-federatedDS-2_0_0-M1
