A Form Inside Another Form

Hello!

I have a form with a table "table1" and another form with "table2". I need to present both forms in a page at same time. I do this using renderPartial in the '_form' or 'create' view from table1 but when I press save button in form "table1" something strange occurs in the insert process. Seems like the insert clause are executed repeatedly, four to six times. Here's my code:

Quote

<?php
/* @var $this StrainController */
/* @var $model Strain */

$this->breadcrumbs=array(
	'Strains'=>array('index'),
	'Cadastrar',
);

$this->menu=array(
	array('label'=>'Listar Strains', 'url'=>array('index')),
	array('label'=>'Gerenciar Strains', 'url'=>array('admin')),
);
?>

<h1>Create Strain</h1>

<?php echo $this->renderPartial('_form', array('model'=>$model)); ?>

<?php echo $this->renderPartial('/strainFacts/_form', array('model'=>$strainFacts)); ?>

public function actionCreate()
	{
		$model=new Strain;
                                
                $strainFacts=$this->newStrainFacts($model);		

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

		$this->render('create',array(
			'model'=>$model,
                        'strainFacts'=>$strainFacts
		));
	}
        
        public function newStrainFacts() 
        {
            $strainFacts=new StrainFacts;
                                    
            if(isset($_POST['StrainFacts']))
            {
                $strainFacts->attributes = $_POST['StrainFacts'];
                $strainFacts->save();                
            }
                       
            return $strainFacts;
        }

How to make this functions correctly?
