Zopists, This used to work with the old ZClasses but now it gives me a traceback. <!--#call "propertysheets.properties.manage_changeProperties(foo=REQUEST['foo'])"--> This is in the index_html method of inside a ZClass. Apparently the propertysheets need to be called with a <!--#with--> in order to load the proper namespace. But with what, when it's in a ZClass. I tried self.propertysheets..., but self is no longer recognized either. Anyone have the proper way to change properties with Zope 2. Jason Spisak webmaster@mtear.com
