   Select sets "1" and "" as values

    The select must display the value regardless if it is the proper type or not, so we patch setValue to include the value even it is not present on enum (instead drop the value).
    Typecast patch was extended to not modify the data only convert to proper type if possible, otherwise, keep the wrong value.

    The goal is allow the user see the wrong value with the error message.

a print statement, which causes a SyntaxError.
