Hi All, I have seen in the Struts User's Guide http://jakarta.apache.org/struts/userGuide/dev_validator.html new support for conditionally required fields. I would love to take advantage of this feature but am unclear how to implement this functionality using the Struts validator. I can see from the example in the user guide that the form should contain a property containing an array of dependants that I believe would relate to a form field and its dependants. This combined with adding the attribute "indexedListProperty" referencing the dependants[] in a form field validation definition. But I am unclear on how to use this functionality. Any ideas? Many thanks, Greg
