Property of non-object in laravel 4 - laravel

Question

I'm using laravel 4 and I'm getting this error when I attempt to create a menu with a dropdown
Trying to get property of non-object (View: /Applications/MAMP/htdocs/test/app/views/layouts/master.blade.php) (View: /Applications/MAMP/htdocs/test/app/views/layouts/master.blade.php)
I can't see where I'm going wrong
My master.blade.php
<li class="dropdown">
work<span class="caret"></span>
<ul class="dropdown-menu" role="menu">
#foreach($dropdowns as $dropdown)
<li>
{{ $dropdown->title }}
</li>
#endforeach
</ul>
</li>
My PageController
$currentPage = new Page($pages[0]->id);
$dropdowns = $currentPage->getPagesSelectList("parent", "", "");
return View::make('index', compact('dropdowns'));
My Page model
public function getPagesSelectList($name, $default = "", $js = "", $flag = true)
{
$list = array(
'name' => $name,
'default' => $default,
'js' => $js,
'pages' => $this->getSubPages($flag, $default)
);
return (object)$list;
}
public function getSubPages($flag, $default, $parent = 0, $num = 1)
{
$pages = array();
$pageSql = \Page::where('parent', '=', $parent)->orderBy('num', 'ASC')->get();
foreach ($pageSql as $result)
{
$page = new Page($result->id);
$page->setFromDatabase();
$page->default = $default;
$page->select = '';
if( $page->id == $default )
$page->select = $default;
$page->space = $num;
if(!empty($page))
$pages[] = $page;
$children = $page->getSubPages($flag, $default, $page->id, $num + 1);
if(!empty($children))
$pages[] = $children;
}
return array_flatten($pages);
}

Answer 1

Assuming that the other code works fine, in Blade instead of:
#foreach($dropdowns as $dropdown)
<li>
{{ $dropdown->title }}
</li>
#endforeach
you should use:
#foreach($dropdowns->pages as $dropdown)
<li>
{{ $dropdown->title }}
</li>
#endforeach
This is because in getPagesSelectList you assign result of getSubPages to pages index of array and then you convert array to object.
