This is a weakness in "manage_changeProperties".
Put it into the Collector:

  after "manage_changeProperties" almost completely did
  its work, it wants to return "manage_propertiedForm".
  This objects wants to use "manage_page_header".
  However, apparently, this object is not accessible
  via your "doc".

As a workaround, you have two options:

 1. pass the properties as keyword arguments:

	 doc.manage_changeProperties(foo=bar)

 2. catch ("dtml-try ... dtml-except") the exception and ignore it.
