If I use this in a class

$captcha = new Zend_Captcha_ReCaptcha(); $captcha->setPrivkey(self::CAPTCHA_PRIVATE_KEY) ->setPubkey(self::CAPTHCA_PUBLIC_KEY);

the Zend_Service_ReCaptcha opbject created by the constructor isn't updated. This results in an PHP error later on at rendering, which is done by the Zend Service

'Exception caught by form: Missing public key Stack Trace:
