Calling getState Model method in a custom model method

Question

I have a method in a model and I need the array of state variables. In controller it's easy, simply get an $model object and get the array with

$state = $model->getState();

But in a model all my test always get an error 0 or 503:

class MyModel extends ListModel
{
...
    public function setFiltrosActivos()
    {
        $state = $this->getState();  // 503 error
    }
}

Please, how can I get the state variables in a method inside a model?

Answer 1

Finally I chose to move the entire method from the model to a helper and perform the logic there. Now it's working fine. Thank you.

$model  = Factory::getApplication()->bootComponent('com_mycomponent')->getMVCFactory()->createModel('mymodel', 'Site');
$state = $model->getState();
