[ZPT] reversing a repeat

[Phil Harris]

Richard,

Thanks for replying, but I've already tried something along those lines.

I did though try your suggestion, just in case I'd fsck'd something up:

      <span tal:define="cat python:here.Catalog()" tal:repeat="item
python:cat.reverse() or cat">
        <div class="articleTitle">
          <a class="articleLink" href="" tal:attributes="href item/linkUrl"
tal:content="item/Title">link text</a>
          <div class="email">
            <span tal:replace="here/bobobase_modification_time">timedate
here</span>
            (<a href="mailto:" tal:attributes="href python:'mailto' +
item.email" tal:content="item/author">author</a>)
          </div>
        </div>
        <div class="article" tal:content="item/content"> </div>
        <br />
      </span>
    </div>


I get an attribute error on reverse, it seems that the results from the
Catalog don't have either reverse or sort methods.

Thanks anyway.
