Hi, Tim. I builded out your application and took a quick look at the error. It looks like you're mis-using the zope.schema.Field class and its interface. It should be only used in schema definition, while you are using Field instances as attributes for other objects. For example, you are defining the ObjectId as a field, but are using its instances as objects. That's not a valid use.
I extracted the problematic code to separate file and changed the IField to Interface and Field to ``object`` (though you'll want to use Persistent, i guess) for ObjectId and ObjectRef and it works okay. :-) Or, it might be that I don't fully understand your code and application architecture, so I would like to hear more about it. It looks quite over-engeneered to me. -- WBR, Dan Korostelev _______________________________________________ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
