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

[Christian Klinger]

Sascha,

maybe you can try this:

####
form z3c.listjs.widgets import _ListJsWidget

def CustomListJsWidget(field, request, subwidget=None):
     return _ListJsWidget(field, field, request, subwidget=subwidget)


dfe_widget = CustomWidgetFactory(CustomListJsWidget, 
subwidget=object_widget)

Not sure if it helps....

Christian
