Subject [jira] Created: (CAY-1141) Attribute overrides in SelectTranslator are broken
Date Thu, 27 Nov 2008 21:10:12 GMT
Attribute overrides in SelectTranslator are broken
--------------------------------------------------

                 Key: CAY-1141
                 URL: https://issues.apache.org/cayenne/browse/CAY-1141
             Project: Cayenne
          Issue Type: Bug
          Components: Cayenne Core Library
    Affects Versions: 3.0M5
            Reporter: Andrus Adamchik
            Assignee: Andrus Adamchik
            Priority: Minor
             Fix For: 3.0


CAY_207Test seems to succeed only by coincidence. When I am running it standalone from Eclipse,
it fails; when it is run as a part of the test batch, it succeeds (also work done locally
on some other issues, reshuffled something in the mapping, so the tests started failing even
in batch mode).... 

CAY_207Test.java:

            Manager o1 = DataObjectUtils.objectForPK(context, Manager.class, 1);
            assertTrue(o1 instanceof CAY_207Manager1);

            Object p1 = o1.readProperty("clientContactType");
            assertNotNull(p1); // this fails

Looks like SelectTranslator.appendColumn(..) is at fault. It does not handle correctly multiple
ObjAttributes from peer entities in the same inheritance hierarchy , always forcing VOID type
on all but one subclass (which one is really random and depends on mapping internals). So
this results in a NULL value returned for the affected subclasses.
