I tried that and its only called ONCE as you're binding to a function that manipulates the data. when the data in -> ModelLocator.getInstance().myData changes there is nothing bound to it, since you bound to the function massage data and not the actual data in the model... does that make any sense ?

The snippet I posted is from something I've done that looks like this.... public function set jobs (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 ?
