Bug HTML_Quickform?

Hi folks! I've enconterd what seems to be a bug in the package HTML_QuickForm (ver 3.1.1). When adding a advcheckbox to a form, the form posts not only the element with name originally specified but also the name-value pair of the actual checkbox with an internally generated name according to "__[original name]". The documentation for class HTML_QuickForm_advcheckbox in file advcheckbox.php states this should not be the case; only the element with the origin name should be posted. (See line 24-41 in advcheckbox.php). My idea is that the method HTML_QuickForm_advcheckbox::toHtml() should be edited. Line 193-196 in advcheckbox.php... 193> $this->updateAttributes(array( 194> 'name' => $this->getPrivateName($oldName), 195> 'onclick' => $this->getOnclickJs($oldName) . ' ' . $oldJs 196> )); ...should be replaced with: 193> $this->updateAttributes(array( 194> 'name' => null, 195> 'onclick' => $this->getOnclickJs($oldName) . ' ' . $oldJs 196> )); I've very recently started to explore this package (and PEAR in general) so I can be wrong. Please tell me if that's the case. If not this might be a bug to report. Any help appreciated! Thanks! Markus
