Brian Kalbfus commented on ISIS-2020:
-------------------------------------
When I change
{code:java}
return repositoryService.allInstances(HelloOtherWorldObject.class);{code}
to
{code:java}
return isisJdoSupport.executeQuery(HelloOtherWorldObject.class, null);{code}
then the result looks good to me. Is there a good reason to prefer
repositoryService#allInstances over doing a query like this?
> DataNucleus Federated Datastore functionality not used in query

> 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.
