Hi Rahul,
Looks like you have uncovered a bug in HAPI. I tried it locally and I see
the same thing as you: Basically, the "generateACK()" method is not
actually honoring your ModelClassFactory, so it's trying to instantiate the
2.4 version of the structure.
The easiest workaround is probably to change the valud of MSH-12 on your
message to "2.6" right before calling "generateACK". This will have the
side effect that the MSH-12 value in the ACK message will then be set to
"2.6", so you may need to change it back before doing whatever you are
doing with it.
If you don't mind to submit a report, that would be great. I'm sure we can
get this fixed for the next release of HAPI (which we should have a beta of
fairly soon).
Cheers,
James
