Autocomplete for TextLine that allows custom values

Replying to self: I spoke too soon.
Maybe we should split these last posts off to a new topic?

I do not see a noticeable difference when priming the select2 widget with the vocabulary url. Either with or without this, I see the following:
first row: ajaxselect does not trigger
second row: ajaxselect is being used

Edit to add: if I leave auto_append on in my DG field factory for the subform, and make the retourmenge field optional, then the select2 widget appears (without priming).

@adapter(schema.interfaces.IField, z3c.form.interfaces)
@implementer(z3c.form.interfaces.IFieldWidget)
def ResultsDataGridFieldFactory(field, request):
    """
    A special widget constructor setting up widget parameters for DGF.
    """
    widget = DataGridFieldFactory(field, request)
    widget.allow_insert = False
    widget.allow_delete = False
    widget.allow_reorder = False
    #widget.auto_append = False
    return widget

Almost perfect, but for the unwanted "no value".
