just a guess, the word "myTasks" is served as a key to retrieve the shared object, and the object have multi-locals support. So if the user's locale is Chinese,then the code will return a Chinese version of the shared Object, if it's Japanese, then Japanese version of Shared Object will be returned. how to implement this sharedObject, in flex world it's mostly to be a singleton. cairngorm uses singleton a lot you can check that out.
Do you know why this cup is useful? Because it is empty.
