Using $this when not in object context

[paramwork]

Whenever I use $this in action, I get the "Using $this when not in object context" error.

My controller function is -

 public static function table(Table $table): Table
    {
        return $table
            ->columns([
                Tables\Columns\TextColumn::make('name'),
                Tables\Columns\TextColumn::make('email')
                    ->label('Email')
                    ->searchable()
                    ->action(function (WaitlistSubmission $record): void  {
                         $this->dispatchBrowserEvent('open-post-edit-modal', [
                              'post' => $record->getKey(),
                         ])
                    }),                
                Filter::make('created_at')
                    ->form([
                        Forms\Components\DatePicker::make('created_from'),
                        Forms\Components\DatePicker::make('created_until')->default(now()),
                    ])
            ])
            ->actions([
                Tables\Actions\ViewAction::make(),
                Tables\Actions\EditAction::make(),
            ])
            ->bulkActions([
                Tables\Actions\DeleteBulkAction::make(),
            ])
            ->defaultSort('created_at', 'desc');
    }

Replace $this with $livewire and use $livewire in the arguments of that closure

Please update the documentation, Running actions

[danharrin]

The current docs are correct if you are defining a table on a Livewire component or in a relation manager, it's just if you are defining it in a static resource class where this change matters

[AlyxsonMarques]

from where this $livewire come from? I have the same problem, but in my case I'm trying to dispatchBrowserEvent from inside a nested repeater on a Resource

Undefined variable $livewire

You can inject it aside $get if you want
