[Cppcms-users] comet question

[Frank E. <fra...@an...>]

hi,

i try to build the example from the blogpost

http://art-blog.no-ip.info/cppcms/blog/post/47

and i'm kind of stuck. the example seems not to be really compatible
with the current cppcms version. i adapted the source as follows:

class lpTest : public cppcms::application {
public:
  lpTest(cppcms::service &srv) :
    cppcms::application(srv) {

    dispatcher().assign("^/postMessage$",
                        &lpTest::postMessage, this);
    dispatcher().assign("^/consumeMessage/(\\d+)$",
                        &lpTest::consumeMessage, this, 1);
  }

  void postMessage() {
    if(request().request_method() == "POST") {
      if(request().post().find("message") != request().post().end()) {
        messages.push_back(request().post().find("message")->second);
        broadcast();
      }
    }

    release_context()->async_complete_response();
  }

  void consumeMessage(std::string id) {
    unsigned pos = atoi(id.c_str());

    if(pos < messages.size()) {
      response().set_plain_text_header();
      response().out() << messages[pos];
      release_context()->async_complete_response();
    } else if(pos == messages.size()) {
      waiters.push_back(release_context());
    } else {
      response().status(404);
      release_context()->async_complete_response();
    }
  }

  void broadcast() {
    // send the message to all waiters
    for(unsigned i=0; i<waiters.size(); i++) {
      waiters[i]->response().set_plain_text_header();
      waiters[i]->response().out() << messages.back();
      waiters[i]->async_complete_response();
    }

    waiters.clear();
  }

private:
  std::vector<std::string> messages;
  std::vector<booster::shared_ptr<cppcms::http::context> > waiters;
};

and for main:

  cppcms::service srv(argc, argv);
  booster::intrusive_ptr<lpTest> app = new lpTest(srv);
  srv.applications_pool().mount(app);
  srv.run();

as far as i understand this should work. my problem is that if i start
the application and do a request it gives me the following exception:

Catched excepion [Access to unassigned context] (.../http_context.cpp:144)

it seems like the framework tries to do something with the context
though it has been released by release_context() - what am i missing?
