did you enable auto-extract option for your application in epts service instance configuration?
Ow... I didn't see anything about that in the tutorial. I'm using the Device Simulator. I found the EPTS Configuration menu, but I have no idea about howto filling it (I just check the "autoextract" checkbox, and now my location widget does not work either :' ( )
