Patrick Linskey commented on OPENJPA-212: ----------------------------------------- You don't have a test case handy for this by any chance, do you? > Constructor expression permits no other expressions in SELECT clause > -------------------------------------------------------------------- > > Key: OPENJPA-212 > URL: https://issues.apache.org/jira/browse/OPENJPA-212 > Project: OpenJPA > Issue Type: Bug > Components: query > Affects Versions: 0.9.7 > Reporter: Jacek Laskowski > > It seems that it's impossible to run a query with constructor expression > beside other expressions in SELECT clause. Take a look at the following test > that finishes with ClassCastException when the first element of resultQuery > is returned (the 2nd line of the snippet). Am I doing something plain wrong? > It doesn't work with Hibernate EntityManager 3.3.1, either yet TopLink > Essentials 2.0 BUILD 40 runs fine. > Query query = em.createQuery("SELECT NEW > pl.jaceklaskowski.jpa.PewnaKlasa(p.nazwa, o.imie, o.nazwisko, o.numer), o, > p.nazwa FROM Projekt p JOIN p.chair o"); > List<Object[]> resultQuery = query.getResultList(); > final Object[] firstElementInQueryResult = resultQuery.get(0); > assert firstElementInQueryResult.length == 3; > final Object firstElement = resultQuery.get(0)[0]; > assert firstElement instanceof PewnaKlasa; > final Object secondElement = resultQuery.get(0)[1]; > assert secondElement instanceof Osoba; > final Object thirdElement = resultQuery.get(0)[2]; > assert thirdElement instanceof String; > The exception is as follows (the line number is different though as the test > above is incomplete - no class, imports and alike are shown): > java.lang.ClassCastException: pl.jaceklaskowski.jpa.PewnaKlasa > at > pl.jaceklaskowski.jpa.OpenJPATest.testConstructorExpr(OpenJPATest.java:19) -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
