Hi,
I try to use the Memory adaptor for an EOModel. But on ec.saveChanges()
I get an exception because the EREntityStore
(er.memoryadaptor.ERMemoryEntityStore) cannot be instantiated within the
EREntityStoreFactory. How can I solve that problem?
I have created the EOModel with "Memory" as adaptor, then I lock my EC
and create some EOs and execute ec.saveChanges(). Should I configure
more things?
Thanks
André
