A patch from Chatree Srichart for "The createDataResourceRole service does not check if partyId exists" https://issues.apache.org/jira/browse/OFBIZ-5133

The createDataResourceRole service has a partyId attribute as optional but its implementation method does not check if the partyId exists before creating a DataResourceRole value.
The ensurePartyRole service also has a partyId attribute as optional but its implementation method does not check if the partyId exists before creating a PartyRole value.
