[Zope] Zope Book Example

[Leonardo Mota]

Hi every one.
    Has anyone been able to make Chapter's 10 example "Acquiring
Arguments from other Objects" to work?
    I've followed all the instructions, but my ZSQL Method can't acquire
the value from the folder's property when I access it directly trough
the URL:
        http://localhost:8080/Departments/Sales/requisitionSomethingForm

    I fill out the form and when posting it I get an exception. Using
Zope 2.3 and Zserver it throws a:
        Error Type: Bad Request
        Error Value: ['department_id']Dieter Maurer wrote:
