Hi Stravos, Thanks for example but where "currentResultsSet" come from? from your 1st eofetchspec? example : EOFetchSpecification fs1 = new EOFetchSpecification("ENTITY1", specQualifier1,null); EOFetchSpecification fs2 = new EOFetchSpecification("ENTITY1", specQualifier2,null);
specQualifier1 join with another entity. specQualifier2 is a simple qualifier. I want fs1 union fs2.
