HDIV does not exclude params from validation even after exclusion

Question

I am using HDIV version 3.2.0, excluding a param as below:

registry.addParamExclusions("param1").forUrls("/section/.*");

But when I try to submit the form with "param1"(hidden param and setting value using jQuery), HDIV still validates this parameter and form submission fails.

Thanks for your help!
