Stefan Meyer commented on EXTVAL-46:
------------------------------------
I want to use the skipvalidation conditional expression to use componente
values - as in cross validation.
Very common example:
The user may choose between two payment types via radio buttons. between the
radio buttons are the text fields associated with those payment types:
(0) credit
creditcardnumber [ ]
institute [ ]
( ) debit
bankcode [ ]
accountnumber [ ]
My model looks like this:
class Form {
@Required
private PaymentTypeEnum paymentType;
@SkipValidation(input={"paymentType"},"${0}!='CREDIT')
@Required
@Length(minimum = 6, maximum = 20)
private String creditcardnumber ;
@SkipValidation(input={"paymentType"},"${0}!='CREDIT')
@Required
@Length(minimum = 6, maximum = 20)
private String institute ;
@SkipValidation(input={"paymentType"},"${0}!='DEBIT')
@Required
@Length(minimum = 6, maximum = 20)
private String bankcode ;
@SkipValidation(input={"paymentType"},"${0}!='DEBIT')
@Required
@Length(minimum = 6, maximum = 20)
private String accountnumber ;
}
I want to skip validation for the fields that are not associated with the
selected payment type.
I suggest a property "input" for skipValidation that defines other properties
to be referenced by index (${i}) in the expression. The issue I see is that
this skipoValidation can only be eceuted in extval's second validation phase
and thus is not effective for the validations in the first phase. One would
actually have to move all validations to the second phase??!!!

> Extval seems to be validating in more than one phase. So the skip validation
