But... don't you have to do some validation of the actuall field also in your validwhen-statements??

I think I would write the above qouted statement like this:

One of the "secrets" is to use the label attribute of the field you are validating.

I tried it like this ,

with JSP code as ,

But field invalidated whether you select 'paypal' or 'authorize' , the right part of Boolean statement , like (*this* != null) , this works but not the first part , paymentOption == "authorize" , What seems to be problem here , I declared it as a String , Cant we match string like this ?

What do you mean by label attribute ?
