Thanks Josh! I haven't tried to implement this yet but so far it makes sense.

Re: [flexcoders] Re: binding not updating for ArrayCollection when item changes?
In your custom control, change this: public function set dataProvider(dp:ArrayCollection):void { _dp = dp; trace(this fires when the AC is created, but not when it's contents change); } to something like this: public function set dataProvider(value : ArrayCollection) : void { if (_dp == value) return; if (dataProvider) dataProvider.removeEventListener(CollectionEvent.COLLECTION_CHANGE, handleUpdatedProvider); _dp = value; if (dataProvider) dataProvider.addEventListener(CollectionEvent.COLLECTION_CHANGE, handleUpdatedProvider, ???, ???, true); // Weak listener! handleUpdatedProvider(null); } private function handleUpdatedProvider(event : CollectionEvent) : void { //... do stuff } Note that this is just typed out of the top of my head, probably full of typos, and you need to put the default options in place of ??? when attaching the listener :) -Josh 2009/3/13 John Robinson jrobi...@nycap.rr.com Yeah, I've been directly updating the properties.

[flexcoders] Re: binding not updating for ArrayCollection when item changes?
I don't know if this is your problem but one thing I noticed is youu have an ambiguous set of your enabled property. You have enabled = enabled; which (I assume) is to set the enabled property of your class to the enabled parameter that is passed in. This won't work. You should have this.enabled = enabled; or change one of the parameter names. --- In flexcoders@yahoogroups.com, John Robinson jrobi...@... wrote: I have a strange issue with data binding not updating when an item in an ArrayCollection is changed.

Nice catch! That didn't seem to be causing the problem but thanks for pointing it out.

[flexcoders] Re: binding not updating for ArrayCollection when item changes?
Hi John, I seem to remember that XMLList, like Array, isn't Bindable and doesn't dispatch a propertyChange event. You might try changing the public var to a getter/setter and manually dispatching the event, or change the XMLList to Object; to see if it makes a difference. This is just a shot in the dark, but let us know if it helps. -TH --- In flexcoders@yahoogroups.com, John Robinson jrobi...@... wrote: Nice catch!
