    I have this function on javascript:

    function copyDate(to_date, from_date){
    return to_date.set({
    day: from_date.getDate(),
    month: from_date.getMonth(),
    year: from_date.getFullYear()
    });
    }

    The second line of the function raises an error on IE8 , the error message is similar to yours. ("Null is Null or not an object").
    I have debug it using console.log on firefox and chrome, and it seems no problems on those browser. Can you help me?

    Kind Regards,
