I have object (CList) as items (nested items), but CMenu prohibits any use of Iterable object using only one expression:
protected function normalizeItems($items,$route,&$active)
{
...
...
191: return array_values($items);
}
Jonah, Qiang, please, fix this issue (using next expression etc.):
protected function normalizeItems($items,$route,&$active)
{
if($items instanceof Traversable)
$items = iterator_to_array($items, true);
THANKS!
I’m a n00b still, but could this problem be related?

Stack Trace
#0 /home/content/p/e/p/pepereyes/html/yii/framework/zii/widgets/CMenu.php(111): CMenu->normalizeItems()

The error happens on the same normalizeItems function. However, if I code the layout as this…
<?php
$modelMenuItems = MenuItems::model()->findByPk(1);
$reqmenu[] = $modelMenuItems->findMenuItems('user');
$menuitems = $reqmenu[0][items];
$this->widget('zii.widgets.CMenu',array(
'items'=>$menuitems,
));
?>
it works fine, but I’d like to have a skinny view/thin controller/fat model. What is the problem? Thanks for the help.
I found out that the layout is not getting the data array from the controller; I’m searching why…
