I have embarked on my first effort to create a custom ZClass for a site I am building. It almost works! The problem has something to do with the way the object "id" gets created when I make an instance of my custom ZClass. I am using Zope 2.1.2 and my ZClass inherits from DTML Document. I upgraded to the latest version hoping it would fix the problem. It didn't, so I assume now that I am doing something wrong.
Here is what I am using for my addForm method:
<HTML> <HEAD><TITLE>Add Article</TITLE></HEAD> <BODY BGCOLOR="#FFFFFF" LINK="#000099" VLINK="#555555"> <H2>Add Article</H2> <form action="ArticleClass_add"><table> <tr><th>Id:</th> <td><input type=text name="id"></td> </tr> <tr><th>Title:</th> <td><input type=text name="title"></td> </tr> <tr><th>Author:</th> <td><input type=text name="author"></td> </tr> <tr><th>Summary:</th> <td><textarea name="synopisis" cols="40" rows="10"></textarea></td> </tr> <tr><td></td><td><input type=submit value=" Add "></td></tr> </table></form> </body></html>
The title, author, and synopsis properties are added to my ZClass on a property sheet called "article_info". I include these lines in my add method so that the properties can be filled in at object creation time:
<!--#with "ArticleClass.createInObjectManager(REQUEST['id'], REQUEST)"--> <!--#call "propertysheets.article_info.manage_editProperties( REQUEST)"--> <!--#/with-->
The basic problem is that when I create an instance, the "id" property ends up blank! I see the object in the manage GUI with its id, but when I try to access the "id" of the instance in DTML, I get a value of "<string>" instead of the id I assigned. The other properties, like title and author, get created correctly. The edit page for the new object instance (it is a sub-class of DTML Document) also displays a blank id.
Any clues???
