Code Validation AJAX Error was created by sysopcrew

I'm having trouble with AJAX Code Validation on a normal Checkbox (Multiple) field. I have 5 options, and I want users to be able to possibly select multiple options EXCEPT a specific combo of two (example: options a, b, c, d, f. They can select any except b and c together.) However, I can't get Code Validation with AJAX to work. All profile edits are done via profile view through AJAX fields. Edit Profile only displays the basic username, email, and name. For the sake of testing, I have set the PHP for Code Validation to return false; to force an error. However, when editing the AJAX field, this is thrown in the browser Dev Console as I change check box selections in AJAX editing:

Code:

jquery.cbvalidate.min.js?v=97c6c7d74dea204d:1 Uncaught TypeError: Cannot read property 'valid' of null

Enable debug mode and maximum error reporting in Joomla global configuration then retry. This should allow the error to provide an actual line number that can be investigated to see where in the JS it's failing. Please note your PHP should be returning a true or false only.

For the sake of this test, I have one line of PHP:

Code:

return false;

When I clicked on a checkbox in Profile view, AJAX editing mode:

Looks like something is breaking the validation endpoint. Seams to be working fine in my tests. Please PM backend super administrator login credentials and note what field is failing validation to reproduce your issue and will take a look. It's possible something is doing an echo and breaking the JSON response of the validation endpoint.

That error could only happen if the following check failed.

Code:

if ( ( cbGetParam( $_GET, 'function', null ) == 'codevalidate' ) && $this->canValidate( $field, $user, $reason ) ) {

So either the function value in the URL of the validation endpoint is being altered or the field isn't properly accessible for ajax validation, but if it's not accessible for ajax validation it shouldn't have been possible for it to attempt validation to begin with.
