I discovered that (event.result.people.person.source != null) when the result is an ArrayCollection. So I used that in an if statement so I could choose simply to set my variable equal to the result, or if I had to variable.addItem() the result.
Your way is much neater. I'll give that a try, thanks. L. --- In [email protected], "valdhor" <valdhorli...@...> wrote: > > I use "new ArrayCollection(ArrayUtil.toArray(event.result))".
