Joomla as external library

Hi Jason,

I'm not using Joomla myself, but this is what I think may be the reason (based on screenshot and code on it):

Because of the way how $controller is created and the way how JController::getInstance() is implemented and documented, PhpStorm is unable to properly identify what type is that. You need to help PhpStorm a bit by providing typehint via PHPDoc comment block, something like this:

/** @var My_Controller_Class $controller */
$controller = JController::getInstance('Booking');

Righ now PhpStorm thinks that $controller is instance of class mixed (as seen on your screenshot). If you put your curson on $controller and invoke "View | Quick Documentation", you will see what PhpStorm thinks about this variable exactly. Now, add PHPDoc comment mentioned above and invoke Quick Documentation again.

Thanks for the detailed response, Andriy. That did the trick!
