Hi Peter,

When I use your code in a flex3 project, it works fine.
But when I use flex 4 code I get an error from this line:
var errField:String = FormItem(err.currentTarget.source.parent).label

=> TypeError: Error #1034: Type Coercion failed: cannot convert spark.components::Group@115cad0a1 to spark.components.FormItem

Any tips to solve this ?

Thanks in advance,
James

How can you validate a DropDownList to not be -1 but can be -3 (If the enter thier own value) and incorporate it into your loop? Thanks! This article was perfect for me!

Can we just show labels in red, exactly we see when we do mouse over on field, while pressing on submit button, instead of displaying annoying Alert!

Like we see in jQuery validation plug-in, if anyone had experience of it.

@Monte Aspevig,

Not sure if it is exactly the same issue (or whether you’re using Flex 3.x or 4.x), but you may want to check out http://bugs.adobe.com/jira/browse/SDK-25731 and possibly download the latest Flex 3.6 nightly build from http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+3 and see if that solves the issue.

When using the control.errorString = “”; to reset the form, it appears the required field validation stops working. Neither submitting the form nor tabbing through the fields and leaving a required field blank will trigger the red-outline and tool-top functionality of the form field after setting its errorString property to “”.

@Jon,

Try explicitly clearing the errorString properties for each control also:

private function resetForm(evt:MouseEvent):void {
    shippingName.text = "";
    shippingAddress1.text = "";
    shippingAddress2.text = "";
    shippingCity.text = "";
    shippingState.selectedIndex = -1;
    shippingZipCode.text = "";
 
    shippingName.errorString = "";
    shippingAddress1.errorString = "";
    shippingAddress2.errorString = "";
    shippingCity.errorString = "";
    shippingState.errorString = "";
    shippingZipCode.errorString = "";
}

Why does resetting the form still leave all the inputs as invalid (i.e. red border) ? How do you reset the form completely, so someone can start from scratch?

instead of using an init function to push all validators into an array, I would do this:

>
    id="shippingZipCode_zipCodeValidator"
        source="{shippingZipCode}"
        property="text"
        requiredFieldError="Please enter a zip code in ZIP+4 format."
        domain="{ZipCodeValidatorDomainType.US_ONLY}"  />
 
     id="shippingZipCode_stringValidator"
        source="{shippingZipCode}"
        property="text"
         tooShortError="Please enter a zip code in ZIP+4 format."
        minLength="10" maxLength="10" />
>

Kind regards,

Marc
