Hmm. Not sure how you are adding a property at runtime. Unless you use Proxy, the only ways I can think of won’t generate change events and thus won’t be bindable. And even for Proxy, I’m not sure if the binding subsystem would be able to determine the right change events. -Alex > >On Wed, Apr 29, 2015 at 10:43 AM, Alex Harui <[email protected]> wrote: > >> >> >> On 4/29/15, 8:07 AM, "mark goldin" <[email protected]> wrote: >> >> >Well, I was missing ArrayCollection(dataProvider).refresh() >> >> That probably does work, but updates the entire item renderer, which may >> result in performance issues.
