表单之间的Symfony2交互，验证失败时的问题

Question

我有2个表单，显示以下内容：

它们是动态创建的，而不是来自实体。

我的控制器如下：

<?php
...create the relevant array $rolesListForForm 
$form = $this->createFormBuilder()->getForm(); //create empty form

$HRsInThisProject = $em->getRepository('AppBundle:User')->findUsersByProject($prj);

foreach ($HRsInThisProject as $key => $HR)
    {
    $form->add('roleOf_'.$key, 'choice', array('choices'   => $rolesListForForm, 'required'  => true, 'data' => $HR['role'], 'label' => false, ));
    $form->add('isActive_'.$key, 'choice', array('choices'   => [0 => 'Inactive', 1 => 'Active'] , 'required'  => true, 'data' => $HR['is_active'], 'label' => false, ));
    }

...create the relevant array $HRsInMyDomainForForm 

$form->add('showinactive', 'checkbox', array('label' => 'Show inactive users', 'required'  => false, 'data' => true, ));
$form->add('HRid', 'choice', array('choices' => $HRsInMyDomainForForm,'required' => false, 'placeholder' => 'Choose a resource', 'label' => false, ));
$form->add('role', 'choice', array('choices' => $rolesListForForm,'required' => false, 'placeholder' => 'Choose a role', 'label' => false, ));            
$form->add('save', 'submit', array('label' => 'Save'));     

$form->handleRequest($request);

// If form is valid
if ($form->isValid()) 
    {
    ...lots of logic here to understand if persisting or not stuff on DB, then I simply refresh the current page
    return $this->redirect($this->generateUrl('hr_manage', array('projectID' => $prj->getId())));
    }

//creation of the second form
$formGlobalSearch=$this->createFormBuilder()
->add('username', 'text', array('constraints' => new UsernameExists()))
->add('role', 'choice', array('choices' => $rolesListForForm,'required' => false, 'placeholder' => 'Choose a role', 'label' => false, ))
->add('submitUsername', 'submit', array('label' => 'Search username globally'))
->getForm();

$formGlobalSearch->handleRequest($request);

if ($formGlobalSearch->isValid())
    {
        //persist stuff on DB and refresh current page
        return $this->redirect($this->generateUrl('hr_manage', array('projectID' => $prj->getId())));
    }

return $this->render('HR/show.html.twig', array('projectID' => $prj->getId(), 'hrlist' => $HRsInMyDomain, 'form' => $form->createView(), 'HRs' => $HRsInThisProject, 'formGlobalSearch' => $formGlobalSearch->createView(),));

一切顺利，唯一的问题发生在第二种形式抛出验证错误时。如果它没有正确呈现顶部形式，我看到这样的东西：

以下是树枝的相关部分：

{{ form_start(form) }}
{{ form_row(form.showinactive) }}
<table>
<tr>
    <td>User ID</td>
    <td>Name</td>
    <td>Role</td>
    <td>Started</td>
    <td>Status</td>
</tr>

{% for key, HR in HRs %}
<tr>
    <td>{{ key }}</td>
    <td>{{ HR.name }}</td>
    <td>{{ form_row(form['roleOf_' ~ key]) }}</td>
    <td>{{ HR.started_at|date('Y-m-d H:i:s') }}</td>
    <td>{{ form_row(form['isActive_' ~ key]) }}</td>
</tr>
{% endfor %}
</table>
<br>
Add new resource:
{{ form_row(form.HRid) }}{{ form_row(form.role) }}
{{ form_row(form.save) }}
{{ form_end(form) }}
<br>
Or you can search for a user of ProJacked at global level
{{ form_start(formGlobalSearch) }}
{{ form_errors(formGlobalSearch) }}
{{ form_widget(formGlobalSearch) }}
{{ form_end(formGlobalSearch) }}

有什么想法吗？
