Symptoms
You have a DVM that includes some additional qualifiers. During a lookup operation (dvm:lookupValue) no value is returned if some of the qualifiers are null in the lookup request.
Example:
You have a Domain Value Map that relates City Codes and City Names like in the table below. The DVM contains a couple of additional qualifiers Q1 and Q2 used to resolve ambiguous mapping. Remember that qualifier domains contain information solely to clarify the mapping.
| CityCode | CityName | Q1 (Country) | Q2 (State) |
|---|---|---|---|
| BO | Boston | USA | Massachusetts |
| BELG | Belgrade | USA | North Carolina |
| BELG | Belgrade | USA | Minnesota |
| NP | North Port | USA | Alabama |
Lookup request for CityCode = BO and Q1=USA and Q2=Massachusetts returns "Boston" as result.
Lookup request for CityCode = BO and Q1=USA and Q2=null returns no result.
Lookup request for CityCode = BO and Q1=null and Q2=Massachusetts returns no result.
Lookup request for CityCode = BO and Q1=null and Q2=null returns "Boston" as result.
