[fw-webservices] Multiple calls from Zend_Rest_Client to service

Hi I want to use the same Zend_Rest_Client to do multiple calls to the
same web service but with different methods.

In version 1.6.2 I was able to do this. But in version 1.7 The second
call just returns the result of the first call.

Do I always have to create a new client? Or can I reset it's state. It's
not clear from the reference guide.

Thanks, Meloen
