I have a problem with $template->getParams()

[ngocphuong]

I have a code in Listener.php (template_post_render)

MyClass_MyFile::_writerExtraData($template->getParams(), $containerData);

Content of function _writerExtraData

protected static $_extraContainerData = array();
protected static $_extraParams = array();

public static function _writerExtraData(array $params, $containerData)
{
        self::$_extraContainerData = $containerData;
        self::$_extraParams = $params;
}

$template->getParams() is FULL values but self::$_extraParams lost a some values (ex: selectedTabId)
I can't not use XenForo_Helper_Criteria:ageMatchesCriteria() if it is not full

Thanks you for help.
