Hello, I am starting to use the switchboard api, but for some reason i am getting an error when I try to use it. My code is the following:

import org.switchboard.*;

Switchboard board;

void setup() {
 board = new Switchboard(this);
}

void resultReceived() {

}

And the error that I get is the following:

endOfResults() was not found in class Temporary_2363_2397
You will not be notified when a service is finished.
status() was not found in class Temporary_2363_2397
You will not be receive status messages.

Can anybody help me with this?

Thanks
