I'm using apache commons validation for validating my form.I have this case for which I'm not able to define the rule. I have 4 fields in the form, and the user has to fill in at least one before hitting the submit. How can I validate this?
Also I have a validation something like this in my validation.xml file
As you can see reworkHours depends on the reworked to be NOTNULL, actually I want the reworked field should have a "valid" value before validating the reworkHours field. So can I replace "NOTNULL" in the
<var-value>NOTNULL</var-value> with something which will in fact validate for say as an Integer instead of just NOTNULL.
Any help in the above two question would be really helpful.
