[Grok-dev] ListSequenceWidget - How to change the sequence

[Sascha Boch]

Thanks, Christian. Sounds great, however... I get the following error:

TypeError: ListJsWidget() takes exactly 2 arguments (3 given)

Code: 

class FooEditForm(grok.EditForm):
    grok.context(Foo)
    grok.name('admin')
    
    form_fields = grok.AutoFields(Foo)
    object_widget = CustomWidgetFactory(ObjectWidget, FooField)
    dfe_widget = CustomWidgetFactory(ListJsWidget, 
subwidget=object_widget)

Any ideas? 

Regards,
Sascha
