[BUG]: Passing variables from the controller to the view does not work.

[Roninju]

Describe the bug
There seems to be a communication problem between the controller and the view that causes the variables not to be defined in the view.

This problem happens since version 4.0.0-rc.2+4138

To Reproduce

use Phalcon\Mvc\Controller;

class IndexController extends Controller {
    
    public function indexAction() {
		
	$this->view->setVar('test', 'value'); // This does not work in view
	$this->view->disable(); // This does not work.
	echo $this->view->getVar('test'); // This works in controller.
		
    }
	
}

Details

• Phalcon version: 4.0.0-rc.2+4237 x64 nts
• PHP Version: PHP 7.3.10 x64 nts
• Operating System: Windows 10 x64
• Server: Apache

@Roninju Did you use PHP FPM?

P.S. Are you sure 4.0.0-rc.1 is OK?

The following also does not work for me:

use Phalcon\Mvc\Controller;

class IndexController extends Controller
{
    public function indexAction()
    {		
	$this->view->testVar = 'value';
    }	
}

and output:

Notice: Undefined variable: testVar in ...views/index/index.phtml on line ...

Details:

• Phalcon Version: 4.0.0-rc.2
  • Build Date: Oct 26 2019 19:34:10
• PHP Version: 7.3.9
• OS: linux

@sergeyklay I don't use PHP-fpm.

4.0.0-rc.1 works correctly. The latest version that does not have this problem is phalcon_x64_vc15_php7.3_4.0.0-rc.2+4137_nts.

@ekmst Do you use Apache too? What about PHP SAPI, is it PHP-FPM?

@Roninju @ekmst Can you share how your view is setup in the DI?
Are you using set or setShared() ?

[ekmst]

@sergeyklay
No, I use Nginx in conjunction with FPM

[Jeckerson]

@ekmst Try to declare view service provider with setShared()
Example here:
https://github.com/phalcon/vokuro/blob/4.0.x/src/Providers/ViewProvider.php#L40

[ruudboon]

Confirmed the bug. It works on RC.1 and 3.4. Looks like we reinitialise the View somewhere.
Workaround is defining your view as shared.

// Registering the view component
$di->setShared(
    'view',
    function () {
        $view = new View();
        // Settings
        return $view;
    }
);

[Jeckerson]

After tests with Vokuro

RC.1

Work

$di->set('view', ...)

Work

$di->setShared('view', ...)

---

RC.2

Doesn't work

$di->set('view', ...)

Work

$di->setShared('view', ...)

@Jeckerson
I have the following

// view service (fpm)
$view = new \Phalcon\Mvc\View();

$view->setViewsDir(__DIR__ . '/views/');
$view->setPartialsDir('_partials/');
$view->setLayoutsDir('_layouts/');

$di->set('view', $view');       // Doesn't work

$di->setShared('view', $view);  // But it works

Here is what I noticed. Views do not work when using closure. Below are examples of code and their behaviors in my environment:

It works

    public function registerServices(DiInterface $di): void
    {
        $view = new View();
        $view->setViewsDir(__DIR__ . '/views/');
        $di->set('view', $view);        // It works
        // or
        $di->setShared('view', $view);  // It works
    }

It works

    public function registerServices(DiInterface $di): void
    {
        $di->setShared('view', function () {    // It works
            $view = new View();
            $view->setViewsDir(__DIR__ . '/views/');
            return $view;
        });
    }

Doesn't work

    public function registerServices(DiInterface $di): void
    {
        $di->set('view', function () {   // Doesn't work
            $view = new View();
            $view->setViewsDir(__DIR__ . '/views/');
            return $view;
        });
    }

@ekmst Does your second example work? In that case I think it's only happening with set and not related to the closure.
