[Zope] Zope Control Panel extension

Hello, I found a collateral damage of the suppression of ZClasses in Zope 2.12: eggs that try to add a new item in the Zope Control Panel can do it but they disappear after the initialization phase. Three eggs are concerned: - collective.monkeypatcherpanel (pure Zope2) - Products.PlacelessTranslationService (mainly Plone) - WingDBG (Zope 2 ans Plone) They all use the same code : http://svn.plone.org/svn/collective/collective.monkeypatcherpanel/trunk/coll... Is there a method to add item in the Zope Control Panel without set enable-product-installation to 'on' ? Regards, Encolpe DEGOUTE -- Si ca ne marche pas du premier coup, appelez-le version 1.0.
