Lost data (object) at finish step

[mateuszmalecki]

Hello. Please help me. I have code like this:

public function orderFromFileAction(Request $request){
        $formData = new Order();
        $flow = $this->get('app.form.flow.orderfromfile');
        $flow->bind($formData);

        $form = $flow->createForm();
        if ($flow->isValid($form)) {
            $flow->saveCurrentStepData($form);
            if ($flow->nextStep()) {
                $Form = new Form(); //Object named Form
                $Form->setLength(1000);
                $formData->addForm($Form); //Add object named form to object in $formData
                $form = $flow->createForm($formData);
                var_dump($formData->getForms()); 
                COMMENT: Test variable $formData->getForms(), it works
            } else {
                var_dump($formData->getForms()); 
                COMMENT: Test variable $formData->getForms(), in this moment my information will be lost, i  dont have all information about object and i cant add this to database

                $flow->reset();
                return $this->redirect($this->generateUrl('index')); 
            }
        };
        return array(
            'form' => $form->createView(),
            'flow' => $flow
        );

At first and second step everything is ok, but at third finish step my object Order don't have Forms objects in variable forms. var_dump return null. I don't know why. I can't save entity to database, only can save object Order but without Forms objects. This forms objects are elements created by SymfonyCollections.

Although this data transformation looks strange, it's done only temporarily before rendering the next step(s), but not when finishing the flow.

so how can I save this data to finish step?

Try getting this code out of the if ($flow->nextStep()) {...} block, so that it's called for each step (including the last one).
