Herkese selamlar!

I have a strange problem with my cake (cake_1.2.0.7296-rc2). My start()-action runs twice, under certain circumstances, even though only one request is made.

The triggers seem to be : - loading an object like: $this->Questionnaire->read(null, $questionnaire_id); - accessing $this-data

If I disable the call to loadAvertisement() from the start()-action, this does not happen. If I disable the two calls inside loadAdvertisement(): $questionnaire = $this->Questionnaire->read(null, $questionnaire_id); $question = $this->Questionnaire->Question->read(null, $question_id); ... then it doesn't happen either.

Neden?

Aşağıda benim kodunu görmek, Controller "questionnaires_controller" dir.

function checkValidQuestionnaire($id)
{
    $this->layout = 'questionnaire_frontend_layout';

    if (!$id)
    {
        $id = $this->Session->read('Questionnaire.id');        
    }

    if ($id) 
    {
        $this->data = $this->Questionnaire->read(null, $id);

        //echo "from ".$questionnaire['Questionnaire']['validFrom']." ".date("y.m.d");
        //echo " - to ".$questionnaire['Questionnaire']['validTo']." ".date("y.m.d");


        if ($this->data['Questionnaire']['isPublished'] != 1 
            //|| $this->data['Questionnaire']['validTo'] < date("y.m.d")
            //|| $this->data['Questionnaire']['validTo'] < date("y.m.d")
            )
        {
            $id = 0;
            $this->flash(__('Ungültiges Quiz. Weiter zum Archiv...', true), array('action'=>'archive'));
        }
    }
    else
    {
        $this->flash(__('Invalid Questionnaire', true), array('action'=>'intro'));
    }

    return $id;
}



function start($id = null) {
    $this->log("start");

    $id = $this->checkValidQuestionnaire($id);

    //$questionnaire = $this->Questionnaire->read(null, $id);
    $this->set('questionnaire', $this->data);

    // reset flow-controlling session vars
    $this->Session->write('Questionnaire',array('id' => $id));
    $this->Session->write('Questionnaire'.$id.'currQuestion', null);
    $this->Session->write('Questionnaire'.$id.'lastAnsweredQuestion', null);
    $this->Session->write('Questionnaire'.$id.'correctAnswersNum', null);

    $this->loadAdvertisement($id, 0);

    $this->Session->write('Questionnaire'.$id.'previewMode', $this->params['named']['preview_mode']);

    if (!$this->Session->read('Questionnaire'.$id.'previewMode'))
    {
        $questionnaire['Questionnaire']['participiantStartCount']++;
        $this->Questionnaire->save($questionnaire);
    }        

}




function loadAdvertisement($questionnaire_id, $question_id)
{

    //$questionnaire = array();
    $questionnaire = $this->Questionnaire->read(null, $questionnaire_id);

    //$question = array();
    $question = $this->Questionnaire->Question->read(null, $question_id);

    if (isset($question['Question']['advertisement_id']) && $question['Question']['advertisement_id'] > 0)
    {
        $this->set('advertisement', $this->Questionnaire->Question->Advertisement->read(null, $question['Question']['advertisement_id']));
    }
    else if (isset($questionnaire['Questionnaire']['advertisement_id']) && $questionnaire['Questionnaire']['advertisement_id'] > 0)
    {
        $this->set('advertisement', $this->Questionnaire->Question->Advertisement->read(null, $questionnaire['Questionnaire']['advertisement_id']));
    }

}

I really don't understand this... it don't think it's meant to be this way. Any help would be greatly appreciated! :)
