Probably ECP should not be allowing this error through to AERI, but...

It looks as if some model with a Pivot IntegerValue element has been displayed by an EMF tool that expects more EMF compliance for Values than is currently provided. ValuesFactoryImpl.create has no support.

Currently primitive Value instances are immutable singletons making argument-less construction pointless. Should dummy value-less instances be created for the benefit of the EMF createChildren API? Should IntegerValue have revealed that it had no children and so avoided the problem?
