I have this model

namespace Project\Models;

use Phalcon\Mvc\Model;
use Project\Behaviors\xBehvior;
class X extends Model
{
    // ... opted-out code
    public method initialize()
    {
        $this-addBehavior(new xBehavior());
    }
    // ... opted-out code
}

And a behavior

namepsace Project\Behaviors;

use Phalcon\Mvc\Model\Behavior;
use Phalcon\Mvc\Model\BehaviorInterface;
class xBehavior extends Behavior implements BehaviorInterface
{
    // ... opted-out code
    public function any()
    {
        return ['val1', 'val2', 'val3'];
    }
    // ... opted-out code
}

And a repository

namespace Project\Repositories;

use Project\Models\X;
class xRepository extends X
{
    public function doOperation()
    {
        $result = self::find();
        return $result->any();
    }
}

When I call ($xRepository->doOperation()) it should return ['val1', 'val2', 'val3'], but it throws an exception that method any() is undefined. Do I did something wrong ?

I found that if you want to call a behavior method from model, you should use ($this->behaviorMethod()) way since the behavior is initialized and binded to the model whenever you request it.

any() is part of the behavior and you call it from the model. You can fire an event with fireEvent('eventName')

namepsace Project\Behaviors;

use Phalcon\Mvc\Model\Behavior;
use Phalcon\Mvc\Model\BehaviorInterface;
use Phalcon\Moc\ModelInterface;

class xBehavior extends Behavior implements BehaviorInterface
{
    public function notify($eventName, ModelInterface $x)
    {
        if ($eventName === 'superEvent') {
            return ['val1', 'val2', 'val3'];
        }
    }    
}

and then in your repositorie

namespace Project\Repositories;

use Project\Models\X;
class xRepository extends X
{
    public function doOperation()
    {
        $result = self::find();
        return $result->fireEvent('superEvent');
    }
}

Good luck

Thanks alot ! But how could "Nestedset" behavior in Phalcon incubator project do this ?

You can call "descendants, ancestors, ...etc" directly from the model. Check this https://github.com/phalcon/incubator/tree/master/Library/Phalcon/Mvc/Model/Behavior
