Error file upload widget and mandatory attribute

[zonky2]

it is not possible to move to the next step if you have an upload field as mandatory and this is not the last step - the file is loaded on the server, but there is always an error message that the file is missing...

e.g. is this a solution: set hack before validate the widget - works at me...
https://github.com/terminal42/contao-mp_forms/blob/master/MPFormsFormManager.php#L434

    public function validateField(FormFieldModel $formField, $step)
    {
// ....
+        // Special hack for upload fields because they delete $_FILES and thus
+        // multiple validation calls will fail - sigh
+        if ($widget instanceof \uploadable && isset($_SESSION['FILES'][$widget->name])) {
+            $_FILES[$widget->name] = $_SESSION['FILES'][$widget->name];
+        }
        
        $widget->validate();

        // HOOK: validate form field callback
        if (isset($GLOBALS['TL_HOOKS']['validateFormField']) && is_array($GLOBALS['TL_HOOKS']['validateFormField'])) {
            foreach ($GLOBALS['TL_HOOKS']['validateFormField'] as $callback) {

                $objCallback = System::importStatic($callback[0]);
                $widget = $objCallback->{$callback[1]}($widget, $this->getFormId(), $this->formModel->row(), $form);
            }
        }

        // Reset fake validation
        if ($fakeValidation) {
            Input::setPost($formField->name, null);
        }
        
-        // Special hack for upload fields because they delete $_FILES and thus
-        // multiple validation calls will fail - sigh
-        if ($widget instanceof \uploadable && isset($_SESSION['FILES'][$widget->name])) {
-            $_FILES[$widget->name] = $_SESSION['FILES'][$widget->name];
-        }

        return !$widget->hasErrors();
    }

You're change only worked by chance. It would not fix the real issue. It would actually cause validation to fail on other pages then 😄
Fixed in eb25a72. Can you check if this works for you?

Please, update to the hotfix branch. You have to test the latest version not just these changes.

o.k. - 3.0.9 works fine!
