[Zope] Updating Zclass object titles

[Laurie Nason]

I am having the same problem - I have an instance of a zclass that I need to
update only a couple of the properties of, not all of them.
The basic idea is that the user checks a checkbox saying I want to update
this property and also some checkboxes for each of the instances that they
want to update.
My dtml document runs through each of the instances selected and then tries
to update the selected properties - however, as the previous email I am
getting no change of the properties!
I do not want to use the catch all of using the REQUEST object and
editProperties.. as there are fields on the form which don't need to be
updated.
Here is my dtml code..

<dtml-in "REQUEST.form.values()">
  <dtml-if "_.str(_['sequence-item'])[:9]=='Specimen_'">
    <dtml-call "REQUEST.set('specimen',_['sequence-item'])"> <---This is the
name/id of the object I need to update
    <dtml-in chkbox>
        <dtml-call "REQUEST.set('keyvalue',_[_['sequence-item']])"> <---This
is the name of the property
        <dtml-call "REQUEST.set('keyname',_['sequence-item'])">     <---This
is the new value of the property
        <dtml-call
expr="_.getitem(specimen).propertysheets.Basic.manage_changeProperties(keyna
me=keyvalue)">
    </dtml-in>
  </dtml-if>
</dtml-in>

Other things I have tried (unsuccesfully of course!):
If I change the dtml-call to dtml-var and it returns none - no mention of an
error
If I try to use dtml-with "_.getitem(specimen)" but still it doesn't change
the property

Any ideas as to how I can do this

Hello all,

I am trying to edit an instance of a ZClass to update the title.  I am using
the dtml-
   <dtml-call "doc.propertysheets.Basic.manage_changeProperties(REQUEST)">
where
  this is in the submit form of a HTML form, with "title" as a field.  This
will update all
 properties except the title. I have l also tried directly updating it by
calling
   <dtml-call
"doc.propertysheets.Basic.manage_changeProperties(title=new_title)">
I have tried trapping exceptions, and neither of these calls raise one.  So
does anybody know
what's the deal?

Sherman
