Hi Mike, Are you sure the responses are being handled concurrently? JS is indeed single threaded, so you should be seeing those responses handled sequentially, although the order in which the requests will return is not guaranteed.
Based on your description, I would suggest disabling the button after sending the request. In both onSuccess() and onFailure() you can re-enable the button. Hope that helps. - Isaac On Tue, Jan 12, 2010 at 7:47 PM, Mike Noordermeer <m...@normi.net> wrote: > Hi, > > I have a small problem with RPC requests and concurrency and would like to > know if what I'm seeing is correct and what's the best way to solve it. > > Situation: > > - Some page with some list and some refresh button/action > - User clicks refresh multiple times > - Multiple RPC requests go out > - onSuccess() gets called multiple times, concurrently, and list gets filled > with duplicate items from different requests > > Is it correct that onSuccess() can run multiple times concurrently?
