[Zope] try tag doesn't seem to work.

[Jay, Dylan]

I am not having much success trying to catch an exception from ZClient.

From the following code

<ol>
<dtml-in locs>
 <li>&dtml-loc_name; 
  <try>
   <dtml-var "WebClient(loc)">
   <dtml-if "WebClient(loc)">
    (ok)
   </dtml-if>
  <except>
    (failed)
  </try>
 </li>
</dtml-in>
</ol>


I get the following error





 Error type:  bci.NotAvailable
 Error value: (10060, 'winsock error') (File:
http://135.9.1.4/cgi-bin/provsn/DenverGetFile.py Line: [])
None None for None
