Description:
It's a copy of the old-jira issue
http://jira.undersunconsulting.com/browse/OFBIZ-466 from Si Chen.
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.

Hi Si & David,
did you know if this issue is still open or we can close it ?
Thanks

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?
