As a quick fix i changed the validator-rules.xml file. I added the
following:
*if (field == undefined) {*
* isValid = true;*
} else if { ....
}
I did this for required and mask rules. This solved the problem for me.
Thanks for your response. Moreover with the version of validator framework i
am using i doubt there is *validwhen* available. I need to double check
that.

When I tell the truth, it is not for the sake of convincing those who do not
know it, but for the sake of defending those that do
