After a lot of debugging i couldn't really figure out why the $stopPropagation() doesn't stop the Form Property from being updated. Maybe it's because I am using wire:model.live?

Anyway I decided to move along and use a temporary property to reset the updated property if the auth check failed

I had this solution already implemented, but somehow the property value is still getting changed.

 public function exceptionHandlesFormPermission($e, $stopPropagation){
        if($e instanceof Exception){
            $this->dispatch('notification.add', [
                'type' => 'error',
                'message' => $e->getMessage(),
            ]);
            $stopPropagation();
        }

    }

Alright, thanks for the helpful tips on the best practices.

Further the issue still persists since your provided solution also throws an exception. The exception was thrown already before and I even get the error message on the client side. Still my variable gets changed. And I don't know why since Livewire docs also state that throwing an exception in updating is enough ..

I am pretty new to the Livewire ecosystem and trying to figure out the following thing.

So I have a component which uses a Trait to determine if a user can perform the updating method on a specific variable. So far so good, the check is working fine by using the updating{Trait} hook. The method throws an exception as I expect it. So I am going to use another hook exception{Trait}. The exception method gets called, a unique message gets dispatched. Now my issue, how am I able to prevent the property from being updated? When i check the request debug it updates the property inside my component. Here's my current used code

   class CustomComponent {

       use CheckFormPropertyPermissions;
	    
        // shouldnt get updated with the updating hook?
        #[HasPermission('someperm')]
        public int|null $someId = null; 


}

	public function updatingCheckFormPropertyPermissions($name): bool{

        $nameParts = explode('.', $name);
        $permission = $nameParts[0];
        $app = config('app.name', env('APP_NAME', ''));
        $name = implode('.', [
            $app,
            $permission
        ]);

        if(array_key_exists($name, $this->propertyPermissionIsAllowed)){
            return true;
        }

        if(!auth()->user()->can($name)){

            throw new Exception('Not allowed!');

        }

        $this->propertyPermissionIsAllowed[$name] = true;

        return true;

    }

    public function exceptionCheckFormPropertyPermissions($e, $stopPropagation){
        if($e instanceof Exception){
            $this->dispatch('notification.add', [
                'type' => 'error',
                'message' => $e->getMessage(),
            ]);
            $stopPropagation();
        }
    }

Maybe someone is able to give me a hint?

Thanks in advance
