Is it possible to manually wrap a form field in a field_with_errors div after validation?

I am adding an error to a field in a form thus: company.errors.add_to_base("Please select either distributor or manufacturer")

However, the add_to_base method doesn't wrap the field where the error occurred in a field_with_errors div, and thus the field isn't highlighted.

Is there any way to achieve this manually?

I tried adding a nil error to the attribute: company.errors.add(:isVertrieb, nil), but this results in the field's name being output in the list of validation errors.
