Hi Alex,
I know it's been a while, but I'm looking into this issue once more.
What exactly did you mean by "add custom message headers and explicitly
map between them". My assumption is:
custom message header =3D=3D property on ODE MessageExchange ??? That's
what we did, anyway.
explicitly map between them: where would we do that?
Thanks,
Bj=F6rn
