I also do have same kind of problem. But I never tried to refresh the array collection. I tied a button to the Httpservice and once the array is populated if you press the button, which send the httpservice request, all the data disappear. Now if you press the button second time, that means send the httpservice request second time, the data shows up with the updated values.
I guess what Alex said is happening in my case. When I first press the button, httpservice returns an empty arraycollection, but when the button is pressed the second time it returns the updated array. But one thing I do not understand- why would it return empty arraycollection? When I coded I expected it to remove all the elements from the array collection and the put the new httpservice request's return result!!!! --- In flexcoders@yahoogroups.com, "Alex Harui" <[EMAIL PROTECTED]> wrote: > > I would think that your service should return an empty array collection, > or return a failure.
