Web service callback problem

Hi,

Edit: posted in wrong forum first, this belongs better in the ABL forum.

I got a problem with calling the same web service multiple times. What I need to do is loop through a number of open sessions and close them.

I basically got 2 different abl programs to do this.

(I'm kind of pseudo-coding here for readability)

The problem is that on the second iteration I get error 11574: Could not process callback: invalid procedure handle for the callback. (11574).

I'm guessing this has to do with the fact that I already set a callback procedure on the first iteration and it's still sticking. I've tried to first deleting any possible callback procedure (calling hService:SET-CALLBACK-PROCEDURE("REQUEST-HEADER", "")) but that doesn't seem to work.

The sign in procedure is quite similar and it works - only real difference is that I'm working with RESPONSE-HEADER there instead.

All ideas appreciated!

Running OpenEdge 10.1C on Sun Solaris.

Best regards

Jens

main.p:

======

CREATE SERVER hServer.

hServer:CONNECT("-wsdl xxxx").

RUN webservice SET hService ON hServer.

FOR EACH session:

     RUN deleteSession.p(INPUT hService).

END.

deleteSession.p

============

main-block:

hService:SET-CALLBACK-PROCEDURE("REQUEST-HEADER", "setRequestSessionHeader").

RUN logoutWebservice IN hService(INPUT glcRequest, OUTPUT glcResponse).

Local procedure setRequestSessionHeader:

/*

Creates a new header
