Re: z3c.unconfigure not unconfiguring subscriber

Thanks Dieter. I was able to find the specific zcml file that registered the subscriber and include it without any side effects. After that the unregistration worked as expected.

For reference, here is the final overrides.zcml:

<configure
    xmlns="http://namespaces.zope.org/zope"
    xmlns:zcml="http://namespaces.zope.org/zcml"
    i18n_domain="plone.app.discussion">

  <include package="z3c.unconfigure" file="meta.zcml" />

  <include package="plone.app.discussion" file="notifications.zcml" />

  <unconfigure>
  <subscriber
      for="plone.app.discussion.interfaces.IComment
           zope.lifecycleevent.interfaces.IObjectAddedEvent"
      handler="plone.app.discussion.comment.notify_moderator"
      />
  </unconfigure>

  <subscriber
      for="plone.app.discussion.interfaces.IComment
           zope.lifecycleevent.interfaces.IObjectAddedEvent"
      handler=".mycomment.notify_moderator"
      />

</configure>

The "unconfigure" has no effect if what should be unconfigured has not yet been configured. As Johannes has already pointed out, the standard way to avoid this it to force a previous configuration by include the correponding package before the "unconfigure".


In another message, you have reported that you have already tried Johannes' suggestion:

You may look in which "ZCML" file (or subpackage) of "plone.app.discussion"
the subscriber is registered and only "include" that file (or subpackage) before the "unconfigure".


I do not see why "include"ing "plone.app.discussion" should cause the problem you observe, though. Maybe, this package uses "overrides" by itself and gets confused (I mistrust the "overrides" feature of ZCML -- it already has surprised my several times). If you cannot localize the subscriber registration, you might try to do your "unconfigure"
outside an "includeOverrides".
