[Till Wimmer]

ok, attachements are not accepted... here is the viewhelper code:

/**
 *
 * @param Tx_Hplusinfo_Domain_Model_Klinik $klinik
 * @param Tx_Hplusinfo_Domain_Model_SearchDemand $demand
 * @param string $as Iteration variable
 * @return string
 */
public function render(Tx_Hplusinfo_Domain_Model_Klinik $klinik,
Tx_Hplusinfo_Domain_Model_SearchDemand $demand, $as ) {
	$isAmbulant = false;
	$isStationaer = false;

	foreach($klinik->getReha() as $klinikreha) {
		foreach($demand->getRehas() as $demandreha) {
			if($klinikreha->getReha()->getUid() == $demandreha) {
				if(!$isStationaer)
					$isStationaer = $klinikreha->getIsStationaer();
				if(!$isAmbulant)
					$isAmbulant = $klinikreha->getIsAmbulant();
				break;
			}
		}
		if ($isAmbulant && $isStationaer)
			break;
	}
	$this->variableContainer->add($as, array('isAmbulant'=>$isAmbulant,
'isStationaer'=>$isStationaer));
	return $this->renderChildren();
}
