gSOAP 2.7.15 Adds a redundant namespace to the message header

Question

Hi, I upgraded my application to use gSOAP 2.7.15 (instead of 2.7.9L). In 2.7.9L I added a code to insert the namespaces to the message header - and it worked fine. In 2.7.15, the namespaces are being inserted automatically but WS-Addressing namespace appears twice!!

Any idea??
