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

Hi,

Please disregard this issue.
I found the problem after exhausted effort and the issue is that on the
server side(JacORB) where the call was originating they forgot to set an
enum attribute which resulted this problem. Since the call was reaching the
device (OmniORB) it was not apparent to debug the problem. I'm surprised
the call was able to marshal without setting the enum attribute. Its also
surprising that preinvoke and postinvoke were called without issues.

Thanks,
Venkatesh
