[Zope] dtml-with and only

[Loren Stafford]

Sorry, I wasn't very explicit in that last message.

I used hasProperty(id) in a similar situation, like this:

  <!--#with "PARENTS[-1]"-->
  <!--#if "hasProperty('button_on') and hasProperty('button_off')"-->
 <td class="navd" align="right">
  <a href="<!--#var absolute_url-->"
  onMouseOver="if (document.images) document.bhome.src='/images/<!--#var
button_on-->'; return true;"
  onMouseOut="if (document.images) document.bhome.src='/images/<!--#var
button_off-->';
  return true;"><img name="bhome"
  src="/images/<!--#var button_off-->" border="0" vspace="0" WIDTH="117"
  HEIGHT="39" ALT="<!--#var title_or_id-->"></a>
 </td>
  <!--#else-->
 <td class="navc" align="right">
  <A HREF="<!--#var absolute_url-->">&lt;&lt;home</A>
 </td>
  <!--#/if-->
  <!--#/with-->
