Hi Asanka, If you are using synapse specific xpath functions like "get-property()" within a xpath 2.0 function you have to use them with the prefix "syn".
i.e: <property xmlns:fn="http://www.w3.org/2005/xpath-functions"; name="MY_VALUE" expression="fn:replace(*syn:* get-property('ERROR_URL_POSTFIX'),'\\/','/')"/> Thanks SumedhaS On Fri, Nov 7, 2014 at
