Adding UNION Dataset on EXISTING INTERFACE using SDK

Question

if anyone done before, please tell me how to do it.
i am getting Unique constraint error.
thanks

Hi Michael Rainey, Unique constraint error was solved, but i am getting some other issue, here is the detail.
i am trying to a add new Dataset(for Union Operation) using ODI SDK on existing Interface.
Scenario:
Dataset1 :
Source DataStore : W_PLM_LISTENTRY_PS
Column Name : ENTRYVALUE , ENTRY_ID
Filter : id=1000
Dataset 2:
Source DataStore : W_PLM_LISTENTRY_PS
Column Name : ENTRYVALUE, ENTRY_ID
Filter : id=2000
Target DataStore(Temporary):
Coloumns : Name , ENTRY_ID
Mapping between DataSet1 and Target Data Store already done in the Interface.
Now I have to add new DataSet as “Dataset2” with UNION Operator and do the mapping in to the same interface through ODI SDK.
Issue:
I have give the ODI SDK code for the below, while running that I am getting following error
Exception in thread "main" java.lang.IllegalArgumentException: Object must not be null
while debugging I found that error occur exactly when the following code was running.
interactiveHelper.performAction(new InterfaceActionOnTargetMappingSetSql("NAME","W_PLM_LISTENTRY_PS.ENTRYVALUE",newDataSet));
Already mentioned that I am using Temporary Target datastore, so changed the target column name as "ENTRYVALUE" instead of “NAME” and modified java code like
interactiveHelper.performAction(new InterfaceActionOnTargetMappingSetSql("ENTRYVALUE","W_PLM_LISTENTRY_PS.ENTRYVALUE",newDataSet));
after this change it working well.
So, it seems when ever target datastore column name not equal to source data store column name I am getting this error.
Is it a bug? or am I doing anything wrong? please let me know.
Thanks

Code:
OdiInstance odiInstance = odiInstanceHandle.getOdiInstance();
ITransactionStatus trans = odiInstance.getTransactionManager().getTransaction(new DefaultTransactionDefinition());
String prdLineSQSILDimInterface="SIL_PLM_InternalOraganizationDimension.W_PLM_INT_ORGANIZATION_D_SQ_INT_ORG";
String sourceDataStore="W_PLM_LISTENTRY_PS";
Collection<OdiInterface> odiInterfaces = ((IOdiInterfaceFinder)odiInstanceHandle.getOdiInstance().getTransactionalEntityManager().getFinder(OdiInterface.class)).findByName(prdLineSQSILDimInterface, "BIAPPS");
OdiInterface interface=null;
for (Iterator iter = odiInterfaces.iterator() ; iter.hasNext() ; )
     interface = (OdiInterface)iter.next();
OdiDataStore odiDataStore = ((IOdiDataStoreFinder) odiInstanceHandle.getOdiInstance().getTransactionalEntityManager().getFinder(OdiDataStore.class)).findByName(sourceDataStore, "BIAPPS");
InteractiveInterfaceHelperWithActions interactiveHelper = new InteractiveInterfaceHelperWithActions(interface, odiInstanceHandle.getOdiInstance(), odiInstanceHandle.getOdiInstance().getTransactionalEntityManager());
DataSet newDataSet=new DataSet(interface,"MySet");
newDataSet.setOperator("UNION");
newDataSet.setOrder(10);
interactiveHelper.performAction(new InterfaceActionAddSourceDataStore(odiDataStore, newDataSet,new AliasComputerDoubleChecker(),new ClauseImporterLazy(),new AutoMappingComputerLazy()));
interactiveHelper.performAction(new InterfaceActionOnTargetMappingSetSql("ENTRY_ID","W_PLM_LISTENTRY_PS.ENTRY_ID",newDataSet));
interactiveHelper.performAction(new InterfaceActionOnTargetMappingSetSql("NAME","W_PLM_LISTENTRY_PS.ENTRYVALUE",newDataSet));
odiInstance.getTransactionalEntityManager().persist(anInterface);
odiInstance.getTransactionManager().commit(trans);
