Hello and thank you for your report!

Could you please add a more precise instruction on how to reproduce the issue (e.g. with code attached that worked before and is broken now)? I just looked into the file history of validate.js. The last change was on April 18, before the release of 3.3.0.

This comment was created with the J!Tracker Application at issues.joomla.org/joomla-cms/4736.

Thank you so much for considering my issue! I am glad to provide you with more information about the issue.
I am sorry I mentioned the incorrect version while posting this issue. I was talking about 3.2.3( also any other 3.2.x) & 3.3.3(also any other 3.3.x). I simply compared the file validate.js in two verions & found that the file has been updated in 3.3.3.

Below is a piece of code to give you a better idea about the custom validation rules which used to worked earlier. Instead of writing the full code, I am writing down certain parts of code which are enough to give you a good idea:

Note: Both the cases have been conducted in joomla! 3.3.3 & above.

CASE 1 (Did not work)

JHtml::_('behavior.formvalidation'); // for including validate.js

window.addEvent('domready', function(){
document.formvalidator.setHandler('radio', function(value) {
var publish1 = document.getElementById("publish1").checked;
var publish0 = document.getElementById("publish0").checked;

 if(publish1 != 0 || publish0 != 0){

        //some code
        return true;
 }
 else{
           //some code
        return false;
 } 

});
});

CASE 2 (Worked with a workaround)

/*
Instead of including the validate.js file from the directory (media\system\js) of 3.3.3 , I copied validate.js from joomla! 3.2.x & included it. As a result, everything worked fine again!
*/

$document = JFactory::getDocument();
$document->addCustomTag(''); // validate.js from joomla! 3.2.x version

window.addEvent('domready', function(){
document.formvalidator.setHandler('radio', function(value) {
var publish1 = document.getElementById("publish1").checked;
var publish0 = document.getElementById("publish0").checked;

 if(publish1 != 0 || publish0 != 0){

        //some code
        return true;
 }
 else{
           //some code
        return false;
 } 

});
});

I know my workaround is not a feasible solution, but it is still better to include a file than to change whole block of validation rules.

Hi, the issue is a bit old and there are currently no update to it. Please check the documentation and create a new issues if this does not work in Joomla 3.4 or later as stated in the documentation: https://docs.joomla.org/Client-side_form_validation. Thanks for your understanding.
