set_radio and set_checkbox have problems with value of 0

[eluser]sparky672[/eluser]
As of this posting, using the latest CI (version 2.1.4), and also have this problem.

Already using quotation marks as per a previous comment...

Code:

<input type="radio" name="active" value="1"  <?php echo set_radio('active', '1') ?> />
<input type="radio" name="active" value="0"  <?php echo set_radio('active', '0') ?> />

I'm a little surprised this bug has lingered for so many years.

As a workaround, I have to create an empty rule...

Code:

$this->form_validation->set_rules('active', 'Status', '');

I'm open to any suggestions for a workaround cleaner than an empty validation rule. Thank-you.
