Exceptions thrown inside DelegatorFactory are not rendered in the console

[tylkomat]

I'm in the process of migrating my applications and other third party dependencies to ZF3. Inside a DelegatorFactory, which delegates the creation process of a ConsoleController, a ServiceNotFoundException is thrown (due to the new case sensitivity of service names) but it is not rendered into the console.

I was stepping through via debugger and everything looks fine (for my not zend framework internals expert eye), quite close to what happens in my ZF2 Application where the Exception is rendered.

I can provide more informations if someone tells me where to look.

The $response = $result->getLast() call holds a Zend\Mvc\Console\View\ViewModel but $this->response holds an empty Zend\Console\Reponse which is what is rendered in the end: nothing.

Hope that helps.

I need a bit more information - where is the $response = $result->getLast() call happening?

Ideally, if you can provide a minimal reproduce case, that will help us verify the issue and provide a fix.

The call happens after the Exception is thrown. I put links to the Lines in my previous comment. The call is in Application.php Line 335.

But I think everything is correct there. I was digging more. So the flow continues with completing the request and a Mvc::EVENT_FINISH is triggered (Application.phpL373). In the end the ConsoleResponseSender is supposed to render the response. Right?

The ConsoleResponseSender::__invoke method is never called. I was not testing for ConsoleResponseSender::sendContent, as my day was over. The ConsoleResponseSenderDelegatorFactory was adding the Listener to the Eventmanager though.

I created a minimal Application since I didn't manage to create a real test case: https://github.com/tylkomat/zf-mvc-console-testcase

Just run php public/index.php run after composer install.
Running a route that does not exist should also render an error message I suppose, but does not.

@weierophinney I found the cause of the problem. Here is the flow:

1. SendResponseLIstener is created
2. ConsoleResponseSenderDelegatorFactory delegates creation
3. Delegator calls getEventManager on ConsoleResponseSender
4. new Eventmanager is created and initialized
5. SendResponseEvent is attached
6. because of EventManagerAwareInterface a new Eventmanager is created and added to SendResponseListener which results in the loss of the event attached by the Delegator

@tylkomat is this resolved with zend-mvc 3.0.3?

@finalxcode Thanks for reminding me 🥇
