[Zope] How do reset a dtml-var

[Meilicke, Scott]

variables set by dtml-let are only in the namespace in between the dtml-let
tags.  When you close the tag, the variables are removed.  If you can't use
dtml-let tags, you can push the variable into REQUEST with:

(not tested)

<dtml-call "REQUEST.set('revision','%')">

Hi,

I am trying to check to see if the dtml-var revision is set to a null and if
it is I want to set it to "%" as a sql wildcard. This is my test.

<dtml-if expr="revision==''">
<p><dtml-var revision>test if1</p>
<dtml-let revision="'%'">
<p><dtml-var revision>test if2</p>
</dtml-let>
<p><dtml-var revision>test if3</p>
</dtml-if>

Here are my results.
test if1
%test if2
test if3

How come the variable is not set after I leave dtml-let statement? Thanks.
