These methods were generated when rendering the ListBox and with the id of the ListBox in their name. However, a customer reported the following problem on Accounting Periods ListBox:

1. Display Accounting Period ListBox on ZEO-1. => The ListBox will be rendered and 'listbox_period_list_*' methods will be generated on ZEO-1.
2. Click on 'Next Page' button and the user is redirect to ZEO-2 where the ListBox has never been generated. => The method does not exist yet and thus a 404 error is raised.

Instead of having one method per ListBox ID, only one is now created (eg listbox_setPage() for SelectionTool.setPage()) at Zope startup and the ListBox ID previously defined in the method name is now defined in the value attributes of the buttons.
