Yes. Create a new widget each and every time. I'm not sure about the
performance impact though, but I don't think it should be too hard.
Or - if you know that there are only so many different widgets, create a
instance for each different version, and decide on which one to return
in the controller method.
Don't mess with one widget instance!!!! It is shared amongst the
different requests, and you get race conditions then!
