radio elements are unchecked when added to a form

[sbraz]

Hi,
When creating a radio element and adding to it a checked attribute, the attribute is properly displayed.
However, when the element is added to a form, its checked attribute is removed.

There is no such problem with checkbox elements.

This is the line that removes the attribute:

HTML_QuickForm/QuickForm/radio.php

Line 216 in f5c7da3

$this->setChecked(false);

And this is the traceback to its call:

#0 /tmp/HTML/QuickForm.php(634):
HTML_QuickForm_radio->onQuickFormEvent('updateValue', NULL,
Object(HTML_QuickForm))
#1 /tmp/test.php(9):
HTML_QuickForm->addElement(Object(HTML_QuickForm_radio))
#2 {main}

The onQuickFormEvent function is slightly different for checkbox elements, maybe it
needs to be changed but I don't really know what a change implies:

The following test code demonstrates the problem:

<?php
require_once "HTML/QuickForm.php";
$elem = HTML_QuickForm::createElement("radio");
$elem->setChecked(true);
$qf = new HTML_QuickForm();
echo "ELEM\n";
$elem->display();
echo "\n\nFORM";
$qf->addElement($elem);
$qf->display();
echo "\n";

Result:

ELEM
<input type="radio" id="qf_163e0a" checked="checked" />

FORM
<form action="test.php" method="post" name="" id="">
<div>
<table border="0">

        <tr>
                <td align="right" valign="top"><b></b></td>
                <td valign="top" align="left">  <input type="radio"
id="qf_163e0a" /></td>
        </tr>
</table>
</div>
</form>
