[Zope] edit_propertiesForm traceback

[Jean Jordaan]

Hi Zopers ..

I'm trying to get a Zclass of mine to be properly
catalog-aware. This is turning out to be quite a 
mission, unless I'm seriously astray. 

First I followed the steps in 
  http://www.zope.org/Documentation/How-To/ZCatalogTutorial/
and then I tried to follow 
  http://www.zope.org/Members/AlexR/CatalogAware/
.

Everything seemed to go OK until I attempted to make 
  http://www.zope.org/Members/AlexR/CatalogAware/edit_props.zip
work for me. That gets me:

  <P>
  <STRONG>Error Type: TypeError</STRONG><BR>
  <STRONG>Error Value: string member test needs char left
operand</STRONG><BR> 
  </P>

-->

when I try to edit the properties of an instance of my Zclass. 
Itamar's dtml is a bit too subtle for me to follow at this stage.
Anyone know what's happening? I don't see any "&lt;string&gt;" in
edit_propertiesForm, which is what triggers this traceback.
