[Zope] <dtml-in> sorting problem

[Michael Bernstein]

Hello all,

Here's my problem: I want to sort a list of objects on a property that
not all items have. So I'm doing this:

<dtml-in sort=someProperty,someOtherProperty>

The problem is that those items that have a blank someProperty are
listed first, when I want them at the bottom of the list. I don't want
to reverse the entire sort order, I just want blank values treated as
being larger than any other value.

Any suggestions?
