Symfony 1.4表单未在模板上呈现

Question

My symfony 1.4 application's form is not rendering on template.Template is loading properly.Without form attributes it's loading nicely.When add a new form in controller and load it to the template only i'm getting a blank page.Why is that?

Update:

Following is my php error log content.

Fatal error: Class 'LoginForm' not found in C:\wamp\www\symfony_app\apps\symfony_app\modules\user_login\actions\actions.class.php on line 21

This is the solution which i came up with to this.I was first created a seperate form class by extending symfony base form.At that point my form didn't worked.So i added the form's attributes inside the controller's action method instead of defining it in a seperate file.Now it's working fine.

class loginActions extends sfActions
{
/**
* Executes index action
*
* @param sfRequest $request A request object
*/
public function executeIndex(sfWebRequest $request)
  {
  $this->form = new sfForm();
  $this->form->setWidgets(array(
    'name'    => new sfWidgetFormInputText(),
    'password'   => new sfWidgetFormInputPassword(),
   ));
  }


}

Update form class content:

class LoginForm extends BaseForm
{
   public function configure()
    {
      $this->setWidgets(array(
      'name'    => new sfWidgetFormInputText(),
      'password'   => new sfWidgetFormInputPassword(),
      ));
    }
}

Now the form thing is working.Previously i was checked with url,

http://localhost/symfony_app/web/login/index.

In this way it didn't worked.But after i access through,

http://localhost/symfony_app/web/symfony_app_dev.php/login/index.

When accessing through this url it's working.
