Calls to COM server are not displayed in seq diag

[Vishal]

Hi All,

I have a COM INPROC server(a dll) and a client(an exe) .I want to generate some sequence diagrams for this client-server call scenario.
I build both the client as well as server in the context of EA and then start executing the client. The client will create a server instance and calls its interface functions.
Now when the execution is finished, I can see only client calls listed in the seq diagram and not the server calls(made by client).

For eg :

void Car::DisplayStatistics()
{
     if(SUCCEEDED(hr))
      {
           // Show my car!
           pStats->DisplayStats();
           hr = pStats->QueryInterface(IID_IEngine, (void**)&pEngine);
      }      
}

In the above code, the call to "DisplayStats" is a call to the COM server but this call doesnt gets displayed in my sequence diagram.
Can somebody explain how can I get the COM sever calls in my sequence daigram.
