Error 404 On View After Create

Hi:

I have a model based on a MySQL updateable view in a multitenant SaaS application. The MySQL view is almost identical to the underlying table, the difference being it doesn't have the MySQL username column the table has; it contains all other columns so it's updateable and the missing column is handled by a trigger on insert and a where clause on retrieve.

The model is as follows:

class VVehicle extends CActiveRecord
{
	public static function model($className=__CLASS__)
	{
		return parent::model($className);
	}

	public function tableName()
	{
		return 'vw_vehicle'; // a MySQL view, not a table
	}
	
	public function primaryKey()
	{
		return 'id'; // same as underlying table PK (int, autoincrement, etc.)
	}
	/**
	 * @return array validation rules for model attributes.
	 */
...

The controller's class is pretty standard:

class VVehicleController extends Controller
{
	public $layout='//layouts/column2';

...

	public function actionView($id)
	{
		$this->render('view',array(
			'model'=>$this->loadModel($id),
		));
	}
	
	public function actionCreate()
	{
		$model=new VVehicle;

		// Uncomment the following line if AJAX validation is needed
		// $this->performAjaxValidation($model);

		if(isset($_POST['VVehicle']))
		{
			$model->attributes=$_POST['VVehicle'];
			if($model->save())
				$this->redirect(array('view','id'=>$model->id));
		}

		$this->render('create',array(
			'model'=>$model,
		));
	}

...

	public function loadModel($id)
	{
		$model=VVehicle::model()->findByPk($id);
		if($model===null)
			throw new CHttpException(404,'The requested page does not exist.');
		return $model;
	}

...
}

I can create a new record just fine, but when the controller redirects to view.php to display it I get an error "404 - The requested page does not exist." which I believe comes from loadModel($id).

The browser shows an incomplete URL:

http://mydomain.com/index.php?r=vVehicle/view&id=

Not having the record id causes the action to fail. I don't understand why it isn't being passed from the if ($model->save()) statement to the redirect right after it. As I explained, the data is saved without any issues and if I provide the id, the view.php works fine.

Any ideas? Thanks for the help.
