Declaration of YumTranslationController::performAjaxValidation() should be compatible with that of YumController::performAjaxValidation()

What steps will reproduce the problem?
1. user/translation/admin

I have found a solution for this. This is not fully tested but it seems to 
work. Edit in YumTranslationController.php file the following functions:
- actionUpdate
- performAjaxValidation
- loadModel

See altered functions below

    public function loadModel($model = false)
    {
        $newmodel=YumTranslation::model()->find('category = :category and message = :message and language = :language', array(
                ':category' => $model->category,
                ':message' => $model->message,
                ':language' => $model->language));

        if($newmodel===null) {
            $translation = new YumTranslation;
            $translation->category = $model->category;
            $translation->message = $model->message;
            $translation->language = $model->language;
            return $translation;
        }

        return $newmodel;
    }

    protected function performAjaxValidation($model, $form)
    {
        //if(isset($_POST['ajax']) && $_POST['ajax']==='translation-form')
        if(isset($_POST['ajax']) && $_POST['ajax'] == $form)
        {
            echo CActiveForm::validate($model);
            Yii::app()->end();
        }
    }

    public function actionUpdate($category = null, $message = null, $language = null)
    {
        $models = array();
            foreach(Yum::getAvailableLanguages() as $language) {
                $tmpModel = new YumTranslation();  // added
                $tmpModel->category = $category; // added
                $tmpModel->message = $message;  // added
                $tmpModel->language = $language; // added

                //$models[] = $this->loadModel($category, $message, $language); // changed
                $models[] = $this->loadModel($tmpModel);
            }

        if(isset($_POST['YumTranslation']))
        {
            $category = $_POST['YumTranslation']['category'];
            $message = $_POST['YumTranslation']['message'];

            foreach($_POST as $key => $translation) {
                if(substr($key, 0, 11) == 'translation') {
                    $lang = explode('_', $key);
                    if(isset($lang[1])) {
                        $lang = $lang[1];
                        foreach(Yum::getAvailableLanguages() as $language) {
                            if($language == $lang) {
                                $model = YumTranslation::model()->find(
                                        'category = :category and message = :message and language = :language ', array(
                                            ':category' => $category,
                                            ':message' => $message,
                                            ':language' => $lang));
                                if(!$model)
                                    $model = new YumTranslation();

                                if($translation != '') {
                                    $model->message = $message;
                                    $model->category = $category;
                                    $model->translation = $translation;
                                    $model->language = $lang;   
                                    $model->save();
                                }
                            }
                        }
                    }
                }
            }
            Yum::setFlash('Translations have been saved');
            $this->redirect(array('admin'));
        }

        $this->render('update',array(
                    'models'=>$models,
                    ));
    }
