[Zope] invalid property value: wrapped object

[Anthony Monta]

Can someone help me read this?  The error_log says:

---
Traceback (innermost last):

I don't know how to read that.  What line number is flagged as the
problem?

>From the log's "other" information, the only thing that looks weird is
this:

lpn	<Folder instance at 8e8a200>

That should be a string instead of a folder instance.  My form said
this:

<tr>
 <th align="right">Is this an LPN program?</th>
 <td><input name="lpn" size="5"><br>If so, put a "1" in the box;
otherwise, leave it blank.</td>
</tr>

That is passed to a method that says this:

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

And the constructor method simply says:

<dtml-with "AAContractZClass.createInObjectManager(REQUEST['id'],
REQUEST)">
  <dtml-call
"propertysheets.aacontract_properties.manage_editProperties(REQUEST)">
  <dtml-call reindex_object>
</dtml-with>

But perhaps the error is elsewhere.  Any pointers gratefully accepted.
