How Do I get error in validator

Question

I have several validators.  When you do something invalid, it highlights the field and has a message displayed if you position to that field.  I understand that you can include an error object in the validator that will cause a popup window with the error.
1) how do you do that?
2) can the window's text be sizable?
3) do I need multiple validators or can I use one and if so how would I change the message to reflect the field being checked?

Answer 1

I tried it and got this error:
//    TypeError: Error #1034: Type Coercion failed: cannot convert mx.validators::NumberValidator@ac37501 to mx.events.ValidationResultEvent.
//    at FSCalc/swapToResultsState()[C:\Flex Builder 3\FSCalc\FSCalc\src\scripts\FSUtil.as:49]
//    at FSCalc/__calculateButton_click()[C:\Flex Builder 3\FSCalc\FSCalc\src\FSCalc.mxml:1195]
//    var validatorArray:Array = new Array();
//    validatorArray.push(numValResidence);
//    validatorArray.push(numValEarned);
//    validatorArray.push(numValOther);
//    validatorArray.push(numValAsset);
//    validatorArray.push(numValDependentCare);
//    validatorArray.push(numValCourtOrdered);
//    validatorArray.push(numValElderly);
//    validatorArray.push(numValRent);
//    validatorArray.push(numValInsurance);
//    var validatorMsgArray:Array = Validator.validateAll(validatorArray);
//    var validatorPassed:Boolean = validatorMsgArray.length == 0;
//    if (validatorPassed) {
//        Alert.show("**Testing** all validator tests passed");
//    else {
//        var validatorErr:ValidationResultEvent;
//        var errorStringArray:Array = [];
//        for each (validatorErr in validatorArray) {
//            var errField:String = FormItem(validatorErr.currentTarget.source.parent).label;
//            errorStringArray.push(errField + ": " + validatorErr.message);
//        Alert.show(errorStringArray.join("\n\n"),
//                "Invalid form", Alert.OK);
I added the error after this ran so the numbers would be off a little, but I'm sure you will understand.
