I have a Zclass whose bases are: ZObject, ZDTMLDocument, _ZClass_for_Renderable I am unable to FTP upload an existing instance. That is, HTML-Kit can open an instance and view the body source, but when I hit save I get an FTP error "426 could not create file". The instance does not have an extension in it's id (i.e., the object id is "overview"), and I do not have a Zope mapping of file extensions to this ZClass type. 1. Does the FTP server see STOR as a new create process, in which case I need to add an file extension to the object id AND create a mapping so Zope knows what type of object to make? (I think not, since I don't want to create a new object, just upload the body again) 2. How can I diagnose this error more? Where do I look? 3. Is there some obvious permission setting I haven't turned on for my ZClass? (I have FTP access mapped to "Change DTML Methods" in the corresponding Product "Define permissions" tab. Though I don't see "Ftp access" as a permission on this zclass under "define permissions" on the class, but it is shown as an inherited permisson. 4. Shouldn't I be inheriting a PUT method from the ZDTMLDocument class? Brad Clements, bkc@murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax AOL-IM: BKClements
