RE: [Java-player-users] Javaclient2 java.lang.ClassCastException: javaclient2.LaserInterface

Hi...
I tried to track the problem... and I have some more stuff that you =
might want to have a look. I manage to obtain the laser interface using:
CODE *******************************************
robot =3D new PlayerClient (host,port);
System.out.println (" Connecting too: "+host+" port: "+port+"...");
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace(); //To change body of catch statement use File | =
Settings | File Templates.
}
laserInterface =3D robot.requestInterfaceLaser(0, =
PlayerConstants.PLAYER_PLAYER_REQ_DEV);
END CODE =
***************************************************************
Although, this seems unstable since sometimes the laser interface is =
null. When I manage to have the laserInterface!=3Dnull I obtain null =
afterwards when I try to call laserInterface.getData(). And if I try to =
check whether the data is ready (laserInterface.isDataReady()) it never =
is...
I hope this helps... and I also hope that is an easy bug since I really =
need to finish an experiment using Player2/stage2 this weekend...
Thank you very much...
Regards...
Hugo

Hi Hugo,
I'll try to see if I can duplicate the problem and will reply shortly=20
with an explanation or a patch.
Thanks for the report!
