hi robert,
i added a simple testcase QueryTest#testPrefetchedCollectionOrderBy that uses the orderby attribute of the CollectionDescriptor.
this test passes without any problems.
The only potential problem i see is in ColllectionPrefetcher#associateBatched().

else
{
ManageableCollection col = createCollection(collectionClass);
for (Iterator it2 = list.iterator(); it2.hasNext();)
{
col.ojbAdd(it2.next());
}
result = col;
}
...
if the collectionClass of CollectionDescriptor does not maintain the order the we have a problem.
Yup that looks like it, I use ManageableCollection, specifically the Set impl but changed to ArrayList impl, it's relying on the Collection to maintain its natural order, hence if the Collection is not sortable, it just adds them as it gets them. (at least this is what I understand from the code). Something has to happen there to tell the user they're full of it, and that you can't sort.
