[Zope] Help ZClasses and Properties.

[Mats Nordgren]

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.

Please Help,

Sincerely,
Mats Nordgren
