Yes it should assuming that the variable of the entire class has the [Bindable] metadata tag specified.

Question is when the Model.someData changes, will my set dataProvider function be called again ? During my testing it appeared to be called when it was first run, but when the model changed the setProvider function was never called again...

So have a setter in the ChartView MXML like so: <bla:ChartView dataProvider="{ModelLocator.someData}"/> And inside the view it looks like so: <mx:Box> <mx:Script> public function set dataProvider( values:XML ):void { ... do stuff here } </mx:Script> ... view stuff here ... </mx:Box> Dimitrios Gianninas Optimal Payments Inc. -----Original Message----- From: [email protected] on behalf of Grant Davies Sent: Sat 2/17/2007 5:57 PM To: [email protected] Subject: RE: [flexcoders] observing a model change in cairngorm gareth, thanks for the response... I think my concern is poluting the model with view specific data... The results of a command is xml and this is set in the model which is an as class (VisitorModel) , the chart bound to the model via its data provider. when the app first starts up, I don't have any xml, a user picks a date range, I hit a web service and get valid xml back, then the chart has to has create a column series based on some labels in the xml, so I need to know when the xml has changed so that the column series can be created and the chart updated. In your example below, does the buildJobsTree just manipulate the data or does it actually do something to the view ?

The snippet I posted is from something I've done that looks like this.... public function set jobs (data:ArrayCollection <data:ArrayCollection> ) : void { _jobs = data; buildJobsTree(_jobs); } Not sure if its the best option.. but it certainly works for me. Either that, or there are some observer classes from Adobe Consulting that allow you to watch changes to your model from the UI. Cheers Gareth.

Grant Davies wrote: Hi guys, I've got my view, model, commands and delegate all running and my view contains a chart. When the model changes for my chart data I need to work the data a little and can't just directly use the binding. do I 1) change my command to fire an event when the model has been updated 2) Is there some way I can observe a model change and then kick of my "data work" a little and not directly bind the chart to the model ?
