BUT this fails because Zope wants the property 'length' to be given an integer value. Why couldn't it simply inherit it from the property definition ? That would have seemed the common sense way to go - otherwise I can't see the need for the initial values.

Try manage_changeProperties, instead. Anthony -- Anthony Baxter <anthony@interlink.com.au> It's never too late to have a happy childhood.
