validator-rules.xml JavaScript fails when field not present in jsp

           Summary: validator-rules.xml JavaScript fails when field not
                    present in jsp

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!

Andrew
