I believe the problem here is not the UID regular expression (which I
verified is working as expected) but the way you're retrieving the
UID. opensocial.DataRequest.send is an asynchronous call which means
it's non-blocking -- after send is executed, your other code will
continue to run until the VIEWER information is available at which
point the callback (userIdResponse in this case) is invoked.
Basically, you're trying to use uid too quickly -- since uid is not
initialized, it defaults to undefined (i.e. 0 or false). Asynchronous
programming has a bit of a learning curve, but it can be very
powerful. If I were you, I would retrieve and store the UID when the
application first loads, then load the user interface that allows a
user to add a movie. Then, you have the UID ready if/when addMovie is
invoked later.
Please let me know if you have any more questions about this issue or
asynchronous programming in general.
