I have a ZClass (derived from Folder). I want to be able to edit the properties in the ZClass, to wit, I have created an index_html file, a manage_editDoctrineFolderForm, and a manage_addDoctrineFolderForm that are stored in the ./doctrineFolder subdirectory. All of the above-identified files, as well as the ZClass file itself, are attached. I have a purplexing problem. Every time I add the ZClass, the proper add form appears and I am able to add the ZClass Folder derivative to the current folder. However, My "Edit" view table does not appear. Moreover, when I click on the Properties tab, only the Title property is shown, and not the other two properties of the object, i.e., a default manage_properties is being used, not the one I designated. I'm also having trouble getting Zope to recoginize my manage_editForm rather than the default forms. I suspect it is inheriting something, but it won't let me override those settings. Another problem is that Zope won't seem to For example, in the attached code, there is an index_html file that is to be invoked when you press the "View" tab in the manage mode. However, doing so presents an error message saying that the variable "status" isn't there. Well, I corrected that error, but it still shows up. (Incidentally, no errors were present when I restarted Zope). This problem is driving me nuts! I'm about to junk Zope altogether because you can't make a proper ZClass work without wiping out zope entirely, reinstalling the thing from scratch, and then installing the corrected class (it seems to be the only way to get Zope to forget the previous mistake). Zope has a memory like an elephant -- but only for your mistakes, not for what you want!. Surely there is a way to make changes in a ZClass show up in Zope. Surely there is a way to get the ZClass to have a decent edit screen other than the default? Diter, I implore you to write a section in your book with examples of products that have custom edit screens/properties/methods but in a way that you don't need a Computer Science degree to understand. Something along the lines of the Minimal product (great idea, but the code didn't always work, and he finished the Sequel before he got to custom Views/property sheets). The files are attached. I would appreciate (greatly) any help someone could offer.
