Re: [flexcoders] [Flex 2][ArrayCollection][Bug] Bindings don't executing when setting AC to a new ArrayCollection()

Mon, 07 Aug 2006 06:05:14 -0700

doesn't that custom setter need to broadcast a change event? 
I'm no AS master yet, but I wouldn't expect the below to work.  Why would a change in sessionUsers fire your getter/setter for sessionUsersToString, eh? 

Try creating a function sessionUsersToString() with this signature
public function sessionUsersToString( acIn:ArrayCollection ) : String {}

Then have
<mx:TextInput id="stringResult" text="{sessionUsersToString( sessionUsers )}"/>

Now, if sessionUsers is changed, binding events should fire, and sessionUsersToString() is triggered.

The Flex components use a little trick to make the binding work. They apply an event listener to a collection.

I'm a little confused, it seems it works o.k in the example?

Whats occurring in the above example?

If you are bound to the ArrayCollection then manipulating the AC itself doesn't re-trigger the binding.  You need to do a re-assignment.  If that isn't working make sure that the variable for your AC is [Bindable] and if you wrote a setter and used [Bindable(event="…")] that you actually dispatched the event.

Subject: [flexcoders] [Flex 2][ArrayCollection][Bug] Bindings don't executing when setting AC to a new ArrayCollection()

Hi,

I'm experiencing a bug with an ArrayCollection. I want to remove the contents and the new state should dispatch a Binding, but this is not happen at all.

I was trying several methods:

* setting to null;
* new ArrayCollection();
* calling removeAll()
* calligin refresh() as well

but nothing happens.

I suppose that this should be a known issue, anyone knows some trick to avoid this problem?

Thanks.
