Invalid CSRF using symfony2 form type - symfony

Question

I'm creating 2 forms in one action and these forms are submitted by jquery ajax to other 2 actions. Now, problem is - only first form works. Edit form throws that csrf token is invalid. Why is that happening? My code:
Creating forms:
$project = new Project();
$addProjectForm = $this->createForm(new AddProjectType(), $project, [
'action' => $this->generateUrl('tfpt_portfolio_versionhistory_addproject'),
'method' => 'POST',
'attr' => ['id' => 'newProjectForm']
]);
$editProjectForm = $this->createForm(new EditProjectType(), $project, [
'action' => $this->generateUrl('tfpt_portfolio_versionhistory_editproject'),
'method' => 'POST',
'attr' => ['id' => 'editProjectForm']
]);
Handling submit edit form (but add form is pretty much identical):
$project = new Project();
$form = $this->createForm(new EditProjectType(), $project);
$form->handleRequest($request);
if($form->isValid()){
//handle form
}
}
The only diffrence between these 2 forms is that edit form have one more field - hidden id. Both are submitted by jquery like that:
var form = $("#editProjectForm")
if(form.valid()){
$("#loader").show();
$.ajax({
type: form.attr('method'),
url: form.attr('action'),
data: form.serialize()
}).done(function(data){
//result
}
});
And i display forms like that:
{{ form_start(editProjectForm) }}
{{ form_errors(editProjectForm) }}
{{ form_widget(editProjectForm.name) }}
{{ form_widget(editProjectForm.id) }}
{{ form_rest(editProjectForm) }}
{{ form_end(editProjectForm) }}
Can somebody point my mistake? Isn't it possible to embed 3 forms in one action? Or i have to generate CSRF other way?
#Edit: I updated symfony to the newest release and now it's working prefect. Seems like this version had a bug or i got some lack of vendors code. Anyway, problem resolved.

I think you have to create two tokens in the controller:
$token_add = $this->get('form.csrf_provider')->generateCsrfToken('add');
$token_edit = $this->get('form.csrf_provider')->generateCsrfToken('edit');
and put in the view in hidden field. And then validate in the controller action that proccess the form
# Here you can validate the 'add' or 'edit' token
if (!$this->get('form.csrf_provider')->isCsrfTokenValid('add', $token)) {
$respuesta = array('mensaje' => 'Oops! Invalid token.',
'token' => $token);
return new Response(json_encode($respuesta));
}
