Chief Delphi - Running two commands in sequence from SendableChooser

Hello, I am having trouble with auto choosers in the smartdashboard. I have two sendable choosers (one for obstacles and one for goals). When I run the code, the commands work like they should, but when autonomous mode ends, the code crashes with no errors.

Here is a snippet:

Robot.cpp:

Code:

void Robot::AutonomousInit() {

        selectedObstacle = (Command*) chooserObstacle->GetSelected();

        selectedGoal = (Command*) chooserGoal->GetSelected();

        selectedObstacle->Start();

}



void Robot::AutonomousPeriodic() {

        Scheduler::GetInstance()->Run();

        if(selectedObstacle->IsRunning() == false) {

                selectedGoal->Start();

        }

}



void Robot::TeleopInit() {

        if (selectedObstacle != nullptr) {

                selectedObstacle->Cancel();

        }

        if (selectedGoal != nullptr) {

                selectedGoal->Cancel();

        }

}

My guess is that the robot is confused because the command group was cancelled? Does a command group get cancelled?

Thanks,
Drew
