Cannot access data from multiple select

[phuclh]

Here is my code:

            Select2::make('Members', 'members')
                ->sortable()
                ->options($users)
                ->configuration([
                    'placeholder'             => __('Choose members who can attend to this task.'),
                    'allowClear'              => true,
                    'minimumResultsForSearch' => 1,
                    'multiple'                => true,
                ]),

The input allows selecting multiple users. But when I dd the request data in model observer, it returns null.

    /**
     * Handle the task "saving" event.
     *
     * @param Task $task
     * @return void
     */
    public function saving(Task $task)
    {
        dd($task->toArray()); // The members is null.
    }

Here is screeshot of the request array:

Hi @phuclh, could you provide all code, with models and Nova models, etc...

I am using Nova 2.0.6, here is my code:

My Resource:

My Model:

My Task Observer

class TaskObserver {

        dd($task->toArray()); // Both of these statement return null for members
    }

@koss-shtukert update error from console.

[phuclh]

@koss-shtukert do you have any ideas?

[koss-shtukert]

@phuclh Try to visit on Wiki MorphToMany relationship and using boot method in your Model, not -TaskObserver In new Release, I'm fix .js issue :)

[ArroWsGM]

@phuclh Maybe, you just forgot getter method in your model:

    public function getMembersAttribute()
    {
        return $this->items->pluck('id')->all();
    }

[koss-shtukert]

@phuclh Any news? Have you solved the issue?
