Disclaimer: I don't use Cairngorm or UM, so I might be wrong! But I do take a keen interest in all that is Flex :)
Basically, in Cairngorm, from your View, you dispatch an event telling your command to do some stuff, and then you wait for the model to change before the view knows to take some action (like say mark the data as saved on-screen, or close a dialog, etc). Which eventually leads to your model being polluted with things like status flags, feedback, and other sneaky things that are really just a back-door direct coupling between command and view that shouldn't really be in your model. When you build a UMEvent, before you dispatch it you say something like myEvent.successCallback = this.thingsWereDoneHandler; myEvent.failCallback = this.somethingWentWrongHandler; dispatchEvent(myEvent); And the UM extensions will keep track of your event, and anything that is kicked off by the command, and will call back into your view object to let it know the success / failure of whatever you may have initiated. -Josh On Fri, Jun 20, 2008 at 10:27 AM, donvoltz <[EMAIL PROTECTED]> wrote: > Thanks for your responses. > > I agree with the idea that binding should work, I have set up 2 > datagrids with the same data provider, the standard data grid works > fine when the model locator is updated, however, the advanced one > does not.
