I had to add
value = value == '||' and [] or value[1:-1].split("|")
to make it working properly with existing data rows:
class MultipleOptionsWidget2(OptionsWidget):
@staticmethod
def widget(field, value, size=5, **attributes):
value = value == '||' and [] or value[1:-1].split("|")
attributes.update(dict(_size=size, _multiple=True))
return OptionsWidget.widget(field, value, **attributes)
Values in the widget were not preselected before the change.
