I did it with plain DTML:

<dtml-if "_.hasattr(aq_explicit,'dirIndex')"><dtml-return dirIndex>
<dtml-else><dtml-return "0">
</dtml-if>

but didn't work. No error, but also no correct sorting. The order of
things is different from that when using no sort= attribute, but I
couldn't figure out what kind of order it is :-(

Even when I just return the id in my dtml method, where you would expect
tree-tag to sort things by id, it doesn't do the sort correctly.

So, anybody an idea what's going on here?
