Description:
------------
HTML_QuickForm_hiddenselect throws a PHP-Warning in function toHtml()if $this->_values is empty. (e.g. not calling loadDbResult() with values )
A quick patch would be to check in hiddenselect.php if $this->_values is an array otherwise return empty string:

77: ...
78: $strHtml = '';
79:
80: /** Patch start */
81: if (! is_array($this->_values)) {
82: return $strHtml;
83: }
84: /** Patch end */
85:
86: foreach ($this->_values as $key => $val) {
...

Expected result:
----------------
No Warning

Actual result:
--------------
Warning: Invalid argument supplied for foreach() in /pear/HTML/QuickForm/hiddenselect.php on line 80
