AW: AW: [omniORB] Usage of _out objects

[Fischer, Clemens]

Exactly,
You have to care for incrementing the object reference count e.g.:

void Server::f(A_out a){
...
  A_var myA = ... // got reference from somewhere
  a = A::_duplicate(myA);
...
}

or if you don't need myA anymore:

void Server::f(A_out a){
...
  A_var myA = ...  // got reference from somewhere
  a = myA._retn(); // now myA does no longer care for ref count
...
}

That gives me
error: no match for 'operator=' in a ...

A is an interface in my idl.
Does that mean that I need to activate the object in the POA to get a 
reference?
