I have problem wich is probbably related to this “array thing”. I am newbee, and this is what I want to do.
1. I created RemoteObject, and get array of object from database.
2. I have resultHandler function that take information from this array of object, by extracting just certain attributes, and putting this in array wich is populated OK, i get trace result of this array. Problem is :

3. Now I am trying to Bind this array in getResultHandler function with dataProvider of repeater components. How can I bind this two components, or I need to use some kind of setter function … and if I do, any idea.

Hello friend,

Label text value gets updated if an array collection gets updated. see below example.

Sorry for exhuming an old post, and maybe it’s a bug in the new Flex version, but I’m a newbie and cannot understand why ArrayCollection properties don’t seem to be bound anymore :
In the following example, Label is never updated :(

import mx.collections.ArrayCollection;
[Bindable] public var array:ArrayCollection = new ArrayCollection([0,0]);

Yes it’s true ! And all Flex newbies have had this problem one time -;) If you want use Array, override push and pop functions in order to refresh the UI part but with ArrayCollection all is “automatic” !
