Daryl Stultz updated OPENJPA-1424:
----------------------------------
Attachment: test.zip
Unit test. Probably not a well-written one. I'm open to suggestions to improve
it.
I run against PostgreSQL. The file database/create_jpa.sql can be used to build
the database (called from the file database/build.sh).
> Out of bounds exception using fetch plan

> I've attached a unit test that exposes it. I've done my best to pare things
> down but it seems anything else I remove makes it go away (there are several
> things that could be removed to make it go away). The unit test passes when
> the exception is thrown.
> In short, this works:
> Query query = em.createQuery("select o from Case as o" +
> " left join fetch o.scheduledAssignments" +
> " where o.scheduleDay = :sd");
> query.setParameter("sd", sd);
> List<Case> allCases = query.getResultList();
> But this doesn't:
> Query query = em.createQuery("select o from Case as o" +
> " where o.scheduleDay = :sd");
> query.setParameter("sd", sd);
> FetchPlan fetchPlan = ((QueryImpl) query).getFetchPlan();
> fetchPlan.addField(Case.class, "scheduledAssignments");
> List<Case> allCases = query.getResultList();
> The test case runs against PostgreSQL. I would really appreciate it if
> someone could verify the test passes under some other database or if it
> fails, under PostgreSQL. Of course it would be even better if an OpenJPA
> expert could find the problem.
> I will also accept suggestions for building a better unit test package.
> Thanks for your help.
