> 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.
