[Zope] Product problems

Hi, I'm trying to build a custom Product using archetypes and so far I have been very successful. However, now I'm trying to set the vocabulary for one of the products to a DisplayList of all the objects of a particular type in my ZODB. The problem is I have no idea how to search for them. The code is here: http://authors.aspalliance.com/aylar/ViewPasteCode.aspx?PasteCodeID=2632 I'm using ZopeFind() but it is not returning anything. My guess is that I'm not using it correctly! Any ideas? Richard --- Outgoing mail is certified Virus Free. Checked by AVG anti-virus system (http://www.grisoft.com). Version: 6.0.449 / Virus Database: 251 - Release Date: 27/01/2003
