Re: [Zope] Zope and Polymorphism

Hi Tres! Am 10-Feb-00 schrieb Tres Seaver:

Or, as an alternative, we could extend the <dtml-in> tag to pass in a filter expression as an additional argument::

<dtml-in name=objectValues filter="self.hasMetaType( 'Document' )">

The implementation would likely need to construct a Python code object by synthesizing a function around the expression

That would be absolutely ok of course. Can I be of any help? Regards, Ingo ------------------------------------------
