[Zope] Problems with adding ZClass instances

[John Morton]

I'm have problems with a ZClass I'm working on that uses Folder as
it's base class and is supposed to install a set of default methods
when it's created. The trouble is that it won't when the webDirectory
is created, but it will when I invoke the same method from a tab afterwards.

Here's the body of webDirectory_add:

<dtml-with "webDirectory.createInObjectManager(REQUEST['id'], REQUEST)">
 <dtml-if createDefaultMethods>
   <dtml-in "default_methods.objectIds()">
   <dtml-try>
      <dtml-call "manage_delObjects(ids=[_['sequence-item']])">
      <dtml-except>
      </dtml-try>
     <dtml-call "manage_clone(
            _.getattr(default_methods, _['sequence-item']), 
            _['sequence-item'], REQUEST)">
  </dtml-in>
  </dtml-if>
</dtml-with>

I'm assuming that the code within the <dtml-with ...> is effectively
opperating in the context of the newly created object, but when the
first manage_clone() is executed, it bombs out in _getCopy,
tripping over on this line:

ob=container._p_jar.importFile(f)

...because whatever container is, it's not a folderish object. 

So what do I need to do to switch to the new webDirectory object at
creation time, so adding methods is automatic?

Thanks,
John.
