David E. Jones commented on OFBIZ-466:
--------------------------------------
I'd appreciate more feedback from Si on this one.
The GenericValue, GenericPK, and GenericEntity objects are designed to always be associated with a delegator. If no delegator is associated it will default to the "default" delegator. However, if you use the makeValue method from a different delegator it will be associated with that delegator...
Is there something you found not working this way Si?

> Creating GenericValues using alternative delegators does not work IF those GenericValues are of entities not defined in the "default" delegator. This is because the entity engine keeps referring back to "default" to look for entity meta definition.
> For example, in GenericDelegator.makeValue(entityName, fields) -
> GenericValue value = GenericValue.create(entity, fields);
> value.setDelegator(this);
> GenericValue is created without passing in a delegator first. So how does it know which delegator to use? GenericEntity.getDelegator() forces a default -
> if (delegatorName == null) delegatorName = "default";
> We've had similar issues when trying to .create(...) or .createOrStore(...) The entity engine needs a GenericPK, which it also looks for from the "default" delegator.
> One work around we found was to create GenericValues this way--
> GenericDelegator altDelegator = GenericDelegator.getGenericDelegator("<alt delegator>");
> EntityReader altReader = altDelegator.getModelReader();
> ModelEntity modelEntity = reader.getModelEntity("<entityName>");
> GenericValue newVal = GenericValue.create(modelEntity);
> newVal.setDelegator(altDelegator);
> newVal.putAll(<Map of values>);
> This can fix the GenericDelegator.makeValue(...) methods, but unfortunately the resulting GenericValue still cannot be stored.
