I wrote a piece of code representing an agent using jade library traveling across containers. My agent has a Cyclic Behavior that use a simple switch-case statements to travel across containers. It runs at the 'Main-Container' then goes to 'Container-1' then goes to 'Container-2' and then goes to 'Container-1' and so on! The problem is here when it wants to come back, it doesn't! There is no error about unknown Container or something like that.

            myAgent.doMove(destination);

            try {

            } catch (InterruptedException e) {

                e.printStackTrace();
            }                
            break;
        }
    }
}
}

is there anyone know why this code doesn't work? thank you! :)

You made a spelling mistake in the Default Switch statement:

destination.setName("Main-Contianer");

Should be:

destination.setName("Main-Container");
