Validwhen confusion?
Hey everybody, Just want to validate a two field match using validwhen: field property=newPass1 depends=required,validwhen arg0 key=prompt.newPass/ var var-namesomething/var-name var-value(*this* == newPass2)/var-value /var /field No matter what I put in the var-value space it always returns true! The required statement works well. Do I miss a library? Regards, Nils

validwhen confusion
Hi All,
I am having trouble getting my mind around the boolean expression
semantics of the validwhen validator. Consider the following example.
I have a form with two possible input groups depending on the user
selection. If the entity is an individual, then I need to require
firstName etc. If the entity is a business then I need to require a
business name. Below is my validation code.
field property=firstName depends=validwhen, mask
arg0 key=prompt.common.firstName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType == individual)/var-value
/var
/field
field property=lastName depends=validwhen, mask
arg0 key=prompt.common.lastName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType == individual)/var-value
/var
/field
field property=ssn depends=validwhen, mask
arg0 key=prompt.common.ssn /
arg1 key=prompt.common.ssn.format /
var
var-namemask/var-name
var-value${ssn}/var-value
/var
var
var-nametest/var-name
var-value(entityType == individual)/var-value
/var
/field
field property=birthDate depends=validwhen, date
arg0 key=prompt.common.birthDate /
var
var-namedatePatternStrict/var-name
var-value${date}/var-value
/var
var
var-nametest/var-name
var-value(entityType == individual)/var-value
/var
/field
field property=businessName depends=validwhen, mask
arg0 key=prompt.common.businessName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType == business)/var-value
/var
/field
However when business is the entityType, firstName, lastName, ssn,
and birthDate show up as required in the error messages. When the
entityType is individual businessName shows up. I thought that the
value was reversed in the jsp, hence reversing it when it is being set
into the form. I debugged the validate method and the enityType is
being set correctly. This operand seems sufficient to work correctly.
However changing all of the == to != seems counterintuitive to me.
It seems to me that my logic should work. {firstName} is required
when {entityType} == individual. Can someone explain the semantics
of the need to negate all of the expressions?
Thanks,
Todd

If the test evaluates to false then it results in an ActionError.
(JavaDocs : Checks if the field matches the boolean expression
specified in test parameter.)
var-value(entityType == individual)/var-value
This says that if entityType is individual then this property
(firstName) satisfies this condition no matter what the value of
firstName is. On the otherhand if entityType == business then this
condition evaluates to false and so this property (firstName) is
tagged as required by the validator. (You should get this message even
if you specify something for firstName)
/var
/field
field property=lastName depends=validwhen, mask
arg0 key=prompt.common.lastName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var

/var

arg0 key=prompt.common.businessName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType == business)/var-value
/var
/field

and birthDate show up as required in the error messages. When the
entityType is individual businessName shows up. I thought that the
value was reversed in the jsp, hence reversing it when it is being set
into the form. I debugged the validate method and the enityType is
being set correctly. This operand seems sufficient to work correctly.

Even if specify something like this,
field property=firstName depends=validwhen, mask
arg0 key=prompt.common.firstName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType != individual)/var-value
/var
/field
it doesn't work as you expect it to, as you can see it fails when
entityType is individual.
So, the right way of specifying the conditionals is to think about
when you don't need that property. For example another of saying
firstName is required when entityType = individual is firstName
is required unless entityType = business
so now you conditional would be
field property=firstName depends=validwhen, mask
arg0 key=prompt.common.firstName /
var
var-namemask/var-name
var-value${alphaname}/var-value
/var
var
var-nametest/var-name
var-value(entityType == business) or
(*this*!=null)/var-value
/var
/field
Which says if entityType=business firstName is not required
otherwise (entityType !=business implicity entityType=individual)
this(firstName) is required
It seems to me that my logic should work. {firstName} is required
when {entityType} == individual. Can someone explain the semantics
of the need to negate all of the expressions?

Todd
