This is a bug in the changes made by Gan to add support for EventChannels.
The problem was the interpreter has code like this:

    // Check whether it is a RT_Event_Channel out port
    std::string out_port_type = oep.out_event_port_type ();
    if (oep.exclusiveProvider())
    {
      if (out_port_type == "Direct_Connect")
         ele->appendChild (this->createSimpleContent ("kind",
                                                           "EventEmitter"));
      else // must be RT Event Channel
         ele->appendChild ele->(this->createSimpleContent ("kind",
                                                          "rtecEventEmitter"));
    }
    else
    {
      if (out_port_type == "Direct_Connect")
         ele->appendChild (this->createSimpleContent ("kind",
                                                   "EventPublisher"));
      else // must be RT Event Channel
         ele->appendChild (this->createSimpleContent ("kind",
                                                      "rtecEventPublisher"));
    }

But the meta-model declares the enum type as "DirectConnect" instead of
"Direct_Connect" as checked by the interpreter.  The easiest solution is to
just search and replace the generated XML file.  This will be fixed in the
next release of CoSMIC.
