if I got it right you need to return a value by reference based on another 
parameter to the same method:

  id=1 ==> usr="one"
  id=2 ==> usr="two"

Currently this is not possible (besides of using a handcrafted method and some 
ReturnObjectList's :-)

There is a class Outbound which could return the value. But it returns one 
after the other, similar to ReturnObjectList. And the decision which 
expectation matches and which object to return is based on all parameters. So 
a potential solution might be to devise a class TriggerOutbound which somehow 
fills in the data when the method is actually invoked (after the parameters 
have been evaluated). Unfortunately all of the objects are completely 
independent of each others. So there must be some kind of bridge to the 
actual variable.

So the solution could look like this:

   Reference<User> *reference= new Reference<User>();
   find_chainer.expect(once())
                      .with(eq(1),
                               reference) 
                      .will(returnValue(true))
                      .will(triggerOutBound(reference))

I will think about this a bit more. Maybe I can find  a nice solution :-)
