[fw-core] Extend Zend_View to provide often used helper methods -- issue

Hi,

I was following the performance guide at http://framework.zend.com/manual/en/performance.view.html#performance.view.pluginloader.extend

But it throws this fatal error...

Notice: Undefined variable: view in C:\... \library\My\View.php on line 22

Catchable fatal error: Argument 1 passed to Zend_View_Helper_Abstract::setView() must implement interface Zend_View_Interface, null given, called in C:\...\library\My\View.php on line 22 and defined in C:\...\library\Zend\View\Helper\Abstract.php on line 50

On line 22 I have...

$this->_localHelperObjects['url']->setView($view);

I have basically copy/pasted the code from the guide.

Also, when I comment out line 22, no errors are thrown. But I don't know if I'm actually having performance benefits by commenting out line 22.

All help is appreciated.
