Cannot receive response from DBus

[Crindu]

I'm creating a custom service and object using QDbus and I'm using D-feet for testing purposes. I noticed that if I put all code in the main class, all works fine, otherwise it crashes.
This works, I can see the service and the object correctly created with d-feet:

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
    QDBusConnection session = QDBusConnection::sessionBus();
    QString myService = QString("test.example");
    QDBusObjectPath agentPath = QDBusObjectPath("/testagent");
    OrgBluezAgent1Interface* agent = new OrgBluezAgent1Interface(myService,agentPath.path(),session);
    Agent1Adaptor adaptor(agent);
    cout << "register service "<<boolalpha<<session.registerService(myService)<<endl;
    cout << "register object " <<boolalpha<<session.registerObject(agentPath.path(),agent)<<endl;


    //busTest b;
    return a.exec();
}

This is the not working version, in particular, D-feet crashes when I try to click on the service created with the following error: org.freedesktop.DBus.Error.NoReply: Message recipient disconnected from message bus without replying.

busTest::busTest(QObject *parent)
    :   QObject(parent),bus(QDBusConnection::systemBus())
{
    QDBusConnection session = QDBusConnection::sessionBus();
    QString myService = QString("test.example");
    QDBusObjectPath agentPath = QDBusObjectPath("/testagent");
    OrgBluezAgent1Interface* agent = new OrgBluezAgent1Interface(myService,agentPath.path(),session);
    Agent1Adaptor adaptor(agent);
    cout << "register service "<<boolalpha<<session.registerService(myService)<<endl;
    cout << "register object " <<boolalpha<<session.registerObject(agentPath.path(),agent)<<endl;
}

I'm also monitoring the dbus messages with dbus-monitor --session
but I cannot find a suitable solution, it seems that something is destroyed in the busTest class and so I cannot receive the dbus response. Thanks

Hi,

Why are you getting both the system and session bus ?

Your Agent1Adaptor object will be destroyed at the end of the constructor.

@SGaist You're right,I did not think about it! I have to remove the systemBus, I'm not using it in reality, it's part of the project that I found on Github. Ok then I can try to make it an instance variable of the class or similer. Thank you!
