Re: Struts Validator and Hidden Field
Octavia, I bit of a guess on my part, but it sounds like you want to use the requiredif validator. This allows a particular field to be required (or not) based on other fields. The fact that this might be a hidden field should be, as pointed out by others, transparent to the validator. However, also pointed out is the most troubling question: if it is on a hidden field and your validation fails, what can your users possibly ever do to correct the situation?

You'll have to post some of your code before anyone will have any idea why it's not working. The Validator also logs copious amounts of info, you should be able to tell if your rule is getting picked up from the XML file by looking in the logs. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University, PA, IRM
Struts Validator and Hidden Field
Hi Everyone, I was wondering if it is possible to validate a hidden field using the Struts Validator framework. If so, an example would be extremely helpful. Thanks in advance! Octavia
Re: Struts Validator and Hidden Field
As far as I was aware validating a hidden field is the exact same as validating any other field.. just make sure the name of the field in your html:hidden corresponds to a setter method in your form. Then create your own validate function within the form to check the variable is correct.. -David - Original Message - From: Octavia Yung [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, August 28, 2003 4:13 PM Subject: Struts Validator and Hidden Field Hi Everyone, I was wondering if it is possible to validate a hidden field using the Struts Validator framework.
