hi, i'm trying to render a form in a modal that has file upload form widget. when i choose a file it will be rendered on the form but as i click on that file for edit or delete it throw this error : "A widget with class name 'formFiles' has not been bound to the controller" on line 517 of /opt/lampp/htdocs/imis-lawyer/modules/backend/classes/Controller.php my createForm function is like this:

public function onCreateForm()
    {
        $dashboard_id = post('dashboard_id');
        $level_id = post('level_id');
        if($this->checkPermission($level_id)){
            $dashboardModel = Dashboard::find($dashboard_id);
            $config = $this->makeConfig($this->levelManager);
            $config->model = new \Imis\ProcessManagement\Models\Dashboard;
            $config->arrayName = 'Dashboard';
            $widget = $this->makeWidget('Backend\Widgets\Form', $config);
            $widget->bindToController();
            $this->vars['widget'] = $widget;
            $this->vars['dashboard_id'] = $dashboard_id;
            $this->vars['dashboard_model'] = $dashboardModel;
            return $this->makePartial('levelmanager/level_manager');
        }else{
            return $this->onShowPassed();

Hello from the future! I have this problem with an Image field. Somebody out there with a tip...?

if you are implementing FormBehavior then write this code in your controller constructor

$this->initForm($this->formCreateModelObject());

Or

as I can see you are writing your own form widget so now you need to bind your controller to your widget for each request made to your controller.

    public function __construct()
    {
        // Your controller code
        $this->getWidget();
    }

    public function onCreateForm()
    {
        $level_id = post('level_id');
        if($this->checkPermission($level_id)){
            $this->vars['widget'] = $this->getWidget();
            $this->vars['dashboard_id'] = $dashboard_id;
            $this->vars['dashboard_model'] = $dashboardModel;
            return $this->makePartial('levelmanager/level_manager');
        }else{
            return $this->onShowPassed();
        }
    }

    public function getWidget(){
        $dashboard_id = post('dashboard_id');
        $dashboardModel = Dashboard::find($dashboard_id);
        $config = $this->makeConfig($this->levelManager);
        $config->model = new \Imis\ProcessManagement\Models\Dashboard;
        $config->arrayName = 'Dashboard';
        $widget = $this->makeWidget('Backend\Widgets\Form', $config);
        $widget->bindToController();
        return $widget;
    }

it will solve the problem.
