I can create instances of a ZClass base on DTMLDocument fom python and they are fine. But when using the management interface, their 'id' gets entered as '<string>'. Also when trying to use: <!--#call "manage_renameObject('old_name','new_name')"--> Zope tells me that 'old_name' doesn't suport this kind of operation. I have already submitted this to the Collector last week, and it is really rendering the application we have created pretty useless because we cannot add these objects to the database. I really need someone out there to help out. I can't give them new id's, and thier is'd are wrong so we are stuck. All my best, -- Jason Spisak webmaster@hiretechs.com
