[Zope] rendering ZClass property

[Timothy Wilson]

Hi everyone,

I'm trying to diplay a property of a ZClass based on whether another
property exists or not. In essence:

if foo_property exists
  print bar_property

Foo_ and bar_property are both properties of the same ZClass. This seems
like it should be easy, but I tried (code snippet):

<dtml-if body>
 <p><b>(a href="/<dtml-var url>/show_article">Read more...</a>)</b></p>
</dtml-if>

When I try this, the if is apparently evaluating to false for all
instances because none of them show the "Read more..." text.

Ideas?

-Tim
