[omniORB] CORBA::is_nil problem

[Attila Pletyak]

Try the following instead of NULL :
Echo_var echoref1 = echo::_nil();

Altough the C++ mapping uses pointers, the concept of pointers is not in 
the CORBA specification. This _nil function is guaranteed to give you an 
empty reference.

Sincerely,

Attila Pletyak
