Qul: Model Property Signals of Singleton class Not Recognized in Auto-generated C++ Code

Girishsonar88

Using Qt MCU 2.11.

//Vehiclemanager.h
class VehicleManager : public Qul::Singleton<VehicleManager> {
public:
friend class Qul::Singleton<VehicleManager>;

Qul::Property<WarningModel*> warningModel;

private:
VehicleManager();
WarningModel m_warn;
};

//WarningModel.h
class WarningModel : public Qul::Object {
public:
WarningModel();

Qul::Property<int> warningState;
Qul::Signal<void()> warningStateChanged;
void setWarningState(VehicleEnums::WarningStates state);

};

//I can able to use properties in QML like this
property int chargeState: VehicleManager.warningModel.warningState

//but i cant able use Signals of same class like below
VehicleManager.warningModel.onWarningStateChanged: {
console.log("warning state changed")
}

//error

//and as it suggested to use WarningModel instead warningModel, if i use that

//error
