[omniORB] corba object method is not being called in the implementer

Hi,
I started seeing a peculiar behavior in the project I'm working on. We use
omniORB on the server side and client uses JacOrb. The issue is on the C++
side ie. on the omniORB side.
Usually to invoke any method on our system the call chain proceeds as
follows
prinvok()
call the c++ method
postinvok()
in preinvoke the servant impl was properly set.
but for some reason, c++ method is not being invoked in between the
preinvoke & postinvoke.
Here is the IDL
interface CardManager
{
char* assignCard(in PhyCard:;PhyCardInfoStruct pcs );
void unAssingCar(in PhyCard::PhyCardInfoStruct pcs );
}
The CardManager implementer is properly set in preinvoke and the operation
argument of the preinvoke correctly shows assignCard
But once the preinvoke is done postinvoke is called without calling the
assingCard C++ implementation.
The PhyCarInfoStruct is a struct type and one of its attribute is a union.
This happens only for this perticular interface. Also after postinvoke I
see there is a SystemException raised which is invalid enum.
It would be really appreciated if you could let me know what could be the
issue. Thanks for your time and help.
Here is the trace snippet for this call with GIOP trace enabled.
