             Summary: Perform query with expression with ObjectId throw NPE in some cases
                 Key: CAY-2541
                 URL: https://issues.apache.org/jira/browse/CAY-2541
             Project: Cayenne

            Reporter: Arseni Bulatski
             Fix For: 4.2.M1


NPE when using expression with ObjectId.

Case:

ObjectId id = new ObjectId("Artist", "ID", 1);

ASTDbPath astDbPath = new ASTDbPath("ID");
ASTScalar astScalar = new ASTScalar(id);

ASTEqual astEqual = new ASTEqual();
astEqual.setOperand(0, astDbPath);
astEqual.setOperand(1, astScalar);

ObjectSelect.query(Artist.class)
 .where(astEqual)
 .selectFirst(context);
