Bug with deleteByQuery and indirection tables ?

[Thomas Dudziak]

When I delete objects that have collections (using indirection tables,
both 1:n or m:n) with deleteByQuery then it seems that the sub-objects are
not deleted even if I use a RemovalAwareCollection. Here is a test case
for MtoNTest that demonstrates this:

    public void testDeletePaper_RemovalAware()
    {
        ClassDescriptor cld = broker.getClassDescriptor(Paper.class);
        CollectionDescriptor cod =
cld.getCollectionDescriptorByName("qualifiers");
        Class collectionClass = cod.getCollectionClass();

        cod.setCollectionClass(RemovalAwareCollection.class);

        try
        {
            Paper paper = createPaper();
            List qualifiers = paper.getQualifiers();
            Qualifier qual1 = (Qualifier) qualifiers.get(0);
            Qualifier qual2 = (Qualifier) qualifiers.get(1);
            Identity paperId = new Identity(paper, broker);

            broker.beginTransaction();
            broker.deleteByQuery(QueryFactory.newQuery(Paper.class,
(Criteria)null));
            broker.commitTransaction();

            broker.clearCache();
            broker.beginTransaction();

            Paper retPaper = (Paper) broker.getObjectByIdentity(paperId);
            assertNull(retPaper);

            Qualifier retQual1 =
(Qualifier) broker.getObjectByIdentity(new Identity(qual1, broker));
            Qualifier retQual2 =
(Qualifier) broker.getObjectByIdentity(new Identity(qual2, broker));

            assertNull(retQual1);
            assertNull(retQual2);

            broker.commitTransaction();
        }
        finally
        {
            cod.setCollectionClass(collectionClass);
        }
    }

Can somebody please confirm whether this is a bug or it is only me doing
something wrong ?

Tom
