All data service calls are asynchronous. This
means you cannot access the return value in the same function in which you
invoke the call.
You must use binding or a handler function
called by the result event.
The data service calls return an
AsyncToken object, which can be used to keep track of what result goes with
what call. It is part of the ACT, Asynchronous Call Token pattern.
Look a little further, post back if you
still have troubles.
