[LiveComponent] sensio/framework-extra-bundle will make your app fail under certain circumstances

[Jim56450]

Hi !

Imagine you create a brand new project using :

symfony new test_live_components --version="6.2.*" --webapp

It installs by default the sensio/framework-extra-bundle.

Now add the symfony/ux-live-component package to your project.

Now, create your components (the one I used was similar to the the Product Form + Category modal).

It uses the Category type-hint between NewCategoryForm.php

$this->emit('category:created', [
            'category' => $category->getId(),
        ]);

and NewProductForm.php

#[LiveListener('category:created')]
 public function onCategoryCreated(#[LiveArg] Category $category): void
{

    $this->category = $category;   
}

The problem is there is a big chance you encounter an 'Unable to guess how to get a Doctrine instance from the request information for parameter "category"' exception when 'onCategoryCreated' is executed. This is because of the presence of sensio/framework-extra-bundle.

You have to remove it to make all this work.

composer remove sensio/framework-extra-bundle

It will work now and hope it will be useful to anybody, avoiding time to debug.

Maybe this could be added to the doc ?

Unfortunately, this doesn't solve the problems exposed here

Thanks for reading,

Marc.

Hey @Jim56450!

Thanks for reporting this! Do you understand WHY SensioFWExtraBundle is having problems? We set category into $request->attributes like a normal request. Perhaps there's a priority problem? Perhaps this code - https://github.com/sensiolabs/SensioFrameworkExtraBundle/blob/2f886f4b31f23c76496901acaedfedb6936ba61f/src/Request/ParamConverter/DoctrineParamConverter.php#L72 - is running before our https://github.com/symfony/ux/blob/2.x/src/LiveComponent/src/EventListener/LiveComponentSubscriber.php#L139

Both listen to ControllerEvent - https://github.com/sensiolabs/SensioFrameworkExtraBundle/blob/master/src/EventListener/ParamConverterListener.php - and both have a priority of 0. I wonder if you switched the order of the bundles in bundles.php (to make LiveComponent) first if that fixes it. If so, we could give our listener a slight positive priority - like 10 - to make sure it runs first.

Hi Ryan,

Thanks for the feedback !

Indeed, if I put back sensio/framework-extra-bundle, the app works great.

If I change bundle.php and set Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle::class => ['all' => true], before Symfony\UX\LiveComponent\LiveComponentBundle::class => ['all' => true], , the app fails.

This must be a priority issue.

Indeed, updating LiveComponentSubscriber.php with

ControllerEvent::class => ['onKernelController', 20],

makes the app work.

Thanks !
