I do have the same problem currently !! I'm learning how to create ZClasses but I tried to create my own. And I can't change properties with manage_changeProperties too. I also read the "ZClasses properties" HOW-TO which tells to uncomment a line "manage_editProperties(REQUEST)" in the "add" method of the ZClass after having modified the "addForm" (added my own properties in the HTML form). But it doesn't change affect properties too ! Is there a ZClass guru to help us somewhere ? Thank you :)) Stephane Baudet. -----Message d'origine----- De : drmental@earthlink.net [mailto:drmental@earthlink.net]De la part de Mats Nordgren Envoyé : jeudi 10 février 2000 16:46 À : zope@zope.org Objet : [Zope] Help ZClasses and Properties. I'm trying to figure out how to use ZClasses and I found myself having problems with the manage_changeProperties for a property of the Class I made. I followed the ZDG ZClass tutorial and created the CDProduct the CDClass, set the property sheet and the class seems to be working ok but I can not for my life get the manage_changeProperties to update the properties of the instance of myCD in the root folder. I can change the properties with the Properties tab of the instance but not through DTML with the line: <dtml-call "myCD.manage_changeProperites({'title':'this title', 'artist':'this artist', 'description':'this desc'})"> It doesn't give me an error or anything it just dont change any property values.
