> Sometimes, esp. when writing a wizard-like interface, not all the form fields 
> will be present in a single jsp - each jsp asks for a subset of the required 
> data from the user. It's useful to validate each piece of data. If you use the 
> validator.xml as supplied, it will fail for rules where the particular field 
> doesn't exist in the jsp.
> I propose adding a check in each of the validators to check if the form field 
> is undefined (i.e. doesn't exist) before attempting to use its properties.
> Each validator must have the following line or similar (in the case 
> of "required") under the for (x in oRequired) { line:
> for (x in oRequired) {
>     if (form[oRequired[x][0]] != undefined) {
> Hope this is of use!
