      I am getting a nullpointerexception like "java.lang.NullPointerException
     com.cisco.connection.rest.impl.ext.UserRestImplExtension.processPostMethod(Unknown Source)" ,when i try to update(PUT) the message settings through my sdl in vsx.But when i try to update(PUT) the playback message settings of an user using poster,it works fine.After the analysis i got to know that in VSX is doing the post method call eventhough if i submit PUT,so please suggest us  how can we update the playback message settings using the same service calls of CUPI-WADL file.
