[Zope] Newbie Question : Problems with Automatic Cataloging of ZClasses

[Dianne Van Dulken]

Hi all, 

I am having a problem with cataloging of zClasses automatically, as defined
by Chapter 9 in the zope book, not actually cateloging anything but the url
and the date.  I know this problem was asked about way back in November, and
Steffan gave the answer that we needed to add the following to the
constructor file of the class:

"<dtml-with "NewsItem.createInObjectManager(REQUEST['id'], REQUEST)"> ( 
this line should already be there )

   <dtml-call "propertysheets.Input.manage_editProperties(REQUEST)">
   <dtml-call unindex_object>
   <dtml-call "manage_editCataloger('inputFilesCatalog', REQUEST)">
   <dtml-call index_object>

'NewsItem' is the name of your class.
'Input' is the name of the property sheet that should be cataloged.
'inputFilesCatalog' is the name of the catalog that should be used.
"

I've done this, matching up the names to what I have them as, but now,
whenever I try to define anything I get the following error:

Presumably something nasty has happened with my date, but I can't for the
life of me work out what it is.  Any ideas would be greatfully accepted.
