in zope 2.2.0, when adding a new zclass the management-screen includes a checkbox "Include standard Zope persistent object base classes?". What does exactly this option do ??????

Surely, there is difference :) I created ZClass with this box unchecked, without any other base classes. Then I can't instantiate any object of that class. (However, when I selected base class 'DTMLDocument' I can make an instance.) If you can't reproduce this behaviour, then maybe it's a symptom of 'boolean property bug' ? (If so, you can apply patch for it, posted by me some time ago). ololo@zeus.polsl.gliwice.pl /--------------------------------------\ | `long long long' is too long for GCC | \--------------------------------------/
