[Zope] Max Length for 'text' property???

Ouch! Just got bit by this thing ... created quite a few zclasses etc all looking good however I only subclassed Catalogaware and Renderable and not DtmlDocument because of sub cataloging problems I was having. Is this the problem - not having a suitable subclass to contain longer text entry? I have a text property called body that I was trying to use to contain any text content for tha instance ... I have a site to present tomorrow and am stumped - anybody have any ideas? Have I gone about this rather rashly?? I /need/ catalog aware and so don't want to use dtml document. Staring disaster in the face Jonathan
