Returns the current data value of the field. The type of value returned is particular to the type of the
particular field (e.g. a Date object for {@link Ext.form.field.Date}), as the result of calling {@link #rawToValue} on
the field's {@link #processRawValue processed} String value. To return the raw String value, see {@link #getRawValue}.
@return {Object} value The field value

        me.value = val;
        return val;
