[Plone] Problème PropertyManager

Bonjour,
Je fais un product et j'ai des petits soucis avec PropertyManager.
Lorsque je fais une instance, d'un type archetype que j'ai créé, dans l'install j'ai un message d'erreur.

En fait, je n'ai pas trouvé de doc, de faq ou de product suffisament détaillés pour m'en inspirer. (Zope book appendix, Zope develloper's guide et même http://docs.neuroinf.de/programming-plone/appendixA#1-3 devraient suffire mais apparement non....)

Si quelqu'un a des infos...(pdeoliveira ou senacle m'avaient donné des réponses que je n'ai pas su les exploitées (http://www.developpez.net/forums/sho...d.php?t=218440)

Je galère un peu mais j'y arriverai!
Merci bien,
biz+++
