[Zope] dtml-in Tag problem

[Jim Sanford]

A traceback is always helpful and would have been useful.

Is it possible that there is a 3rd, empty item, or an item with no ^,  in
"related_stories"?

An empty item when split would return only 1 subitem and
your code is assuming you will always have two.

A test for the ^ in the item before splitting would prevent this.

Try this:
...
<dtml-if "_.string.find(['sequence-item'],'^')!=-1">
    <dtml-let si=sequence-item
        rs_name_url="_.string.split( si, '^' )"
        rs_name="rs_name_url[0]"
        rs_url="rs_name_url[1]">
    <li> <a href="http://<dtml-var rs_url>"><dtml-var rs_name></a></li>
    </dtml-let>
</dtml-if>
...

<dtml-if related_stories>

<dtml-in related_stories>
<dtml-let si=sequence-item
          rs_name_url="_.string.split( si, '^' )"
          rs_name="rs_name_url[0]"
          rs_url="rs_name_url[1]">
<li> <a href="http://<dtml-var rs_url>"><dtml-var rs_name></a></li>
</dtml-let>
</dtml-in>
</font>
</td></tr>
</table>
</dtml-if>

gives me an error that says: "list index out of range"

The related_stories property contains:

King Kong website^www.kong.com
Empire State Building Website^www.empirestate.com

It worked at first but when I made any changes to other properties it gave
me that error message.
Any ideas?
