[Zope] manage_changeProperties Question

[complaw@hal-pc.org]

Forget it.  Used a different tactic.  The following python script works...

for obj in context.objectValues('DTML Document'):
  obj.manage_changeProperties(on_host_committee=0)

I'm not sure why the DTML doesn't, however.  Hmmmm....

Sorry to bother you all.  This is the upteenth time that I've posted a message,
only to figure out the problem about 30 seconds later.
