An error occurred while trying to call Controller->createAction()

Question

I am trying to create something with extbase, but the error-message I get is not very helpful. I took the blog_example extension as a guide. A (maybe) important difference is: I don't have a database table because I want to write a custom domain repository that connects to an external servive through REST.

The actual error message (displayed above the plugin, not as an exception message):

An error occurred while trying to call Tx_MyExt_Controller_SubscriptionController->createAction()

Classes/Controller/SubscriptionController:
Stripped down to the important parts.

class Tx_MyExt_Controller_SubscriptionController extends Tx_Extbase_MVC_Controller_ActionController 
{
    /**
     * @var Tx_MyExt_Domain_Repository_SubscriberRepository
     */
    protected $subscriberRepository;


    /**
     * @return void
     */
    public function initializeAction()
    {
        $this->subscriberRepository = t3lib_div::makeInstance('Tx_MyExt_Domain_Repository_SubscriberRepository');
    }


    /**
     * @param Tx_MyExt_Domain_Model_Subscriber $subscriber
     * @dontvalidate $subscriber
     * @return  string      The rendered view
     */
    public function newAction(Tx_MyExt_Domain_Model_Subscriber $subscriber = null)
    {
            $this->view->assign('subscriber', $subscriber);
    }

    /**
     * @param Tx_MyExt_Domain_Model_Subscriber $subscriber
     * @return  string      The rendered view
     */
    public function createAction(Tx_MyExt_Domain_Model_Subscriber $subscriber)
    { }

}

Classes/Domain/Model/Subscriber

class Tx_MyExt_Domain_Model_Subscriber extends Tx_Extbase_DomainObject_AbstractEntity 
{
    /**
     * @var string
     * @dontvalidate
     */
    protected $email = '';



    /**
     * @param string $email
     * @return void
     */
    public function setEmail($email) 
    {
        $this->email = $email;
    }

    /**
     * @return string
     */
    public function getEmail() 
    {
        return $this->email;
    }
}

Resources/Private/Templates/Subscription/new

<f:form action="create" controller="Subscription" objectName="Subscriber" object="{subscriber}" method="post">
    <f:form.textfield property="email"></f:form.textfield>
    <f:form.submit value="submit"></f:form.submit>
</f:form>

Facts

• Adding $subscriber = null removes the message. But $subscriber is null then
• A var_dump($this->request->getArguments()); displays the form's fields
• There is an index action, and it is also the first action defined in ext_localconf.php

The hints and solutions I found aren't working for me, so I hope someone can guide me into the right direction.

Answer 1

I've got the same bug.

If you pass an Model as argument to an method, it will also validate the model fields.

I've had this annotation on my model property:

/**
 *
 * @var \string
 * @validate NotEmpty
 */

It validates the "@validate" annotation. The field in the database was empty so i got the error message

An error occurred while trying to call ...

It would be good if there was a better error message. You need to customize the validation annotation or verify that the property is not empty in the database

Hope it helps somebody
