[Zope] Updating ZClass instance properties

[Alexandre Ratti]

Thanks Kevin for your suggestion. So far the updating method doesn't belong 
to the ZClass ; I'll change that because it makes more sense anyway.

In the meantime, I've tried several syntactic variants with no luck. I 
still cannot access the class instance object from this method.

I also tried <dtml-with "REQUEST._[id]"> and I get an Unauthorized error 
instead of my usual propertysheet-not-found error. This is strange, because 
I'm superuser.

However, the following code works fine, thought it's kludgy ('news' is the 
folder name):

<dtml-in "news.objectValues(['News'])">
  <dtml-if "id()==REQUEST.id">
   <dtml-call 
"propertysheets.InstanceConstants.manage_changeProperties(REQUEST)">
   <dtml-call reindex_object>
  </dtml-if>
</dtml-in>

Looks like I can access the object indirectly but I cannot access it with 
<dtml-with REQUEST.id> or similar constructs.


Cheers.

Alexandre
