Select of relationship gives "call on null"

Hello, I'm building pretty simple case for an admin panel where Ingredient BelongsTo Menu, so basically I have created an actions EditIngridient and CreateIngridient which returns form of couple fields. One of them is relation of menu. However on edit page/create page I'm getting an error Call to a member function menu() on null. This is my Ingredient descriptions: https://gist.github.com/sanis/c8e0c0a28acd2892c5a3db70a18bc1e3 And this is flare errors: https://flareapp.io/share/4m4BV1Z7 https://flareapp.io/share/VmeMWnzm Any ideas how to fix it and why this is happening? Using filament beta 9.

Made a quick change and this did the trick (calling parent::form($form) on Page form:

return
            parent::form($form)
            ->schema(
                [
                    TextInput::make('code'),
                    Select::make('menu_uuid')->relationship(name: 'menu', titleAttribute: 'code')
                ]
            );

On the original form there are other configurations like ->statePath() which maps the data to $data property. That's why your form broke.

Okay, makes sense.

public function form(Form $form): Form
    {
        return
            $form
                ->model($this->getRecord())
                ->statePath($this->getFormStatePath())
                ->schema(
                    [
                        TextInput::make('code'),
                        Select::make('menu_uuid')->relationship(name: 'menu', titleAttribute: 'code')
                    ]
                );
    }

public function form(Form $form): Form
    {
        return
            $form
                ->model($this->getRecord())
                ->statePath($this->getFormStatePath())
                ->schema(
                    [
                        TextInput::make('code'),
                        Select::make('menu_uuid')->relationship(name: 'menu', titleAttribute: 'code')
                    ]
                );
    }

makes it work. However this wasn't a problem on v2 right?

Dennis Koch•17mo ago

This worked the same way in v2 Oh maybe there was some change, because the form/table syntax is new

sanisOP•17mo ago

it must have been change because it was working before the weekend and now after the weekend (during the weekend I did the upgrade) it's like this :/ Anyhow, there is a solution, but it would be nice to have on the docs as well 🙂 Thanks for your input !
