There are many ways to do what you are looking for, though in a asyncronous manner. Ralf suggested binding a view to a prop on the model, upon updating will update the view. That is probably the most OO way of doing it within the MVC framework. But it also is harder to do more view-specific validation. As for disallowing the user to interact with the app until a response is received, you could basically have your app in a disabled mode until your IResponder triggers on the response. Upon result or fault tell the model to allow further interaction and subsequent validation if applicable.
Awhile back I wrote some articles on doing just this when your design requires a bit more in terms of validation and error handling. You can read up on it here. Would be interested in your thoughts as well. http://jwopitz.wordpress.com/2008/04/24/tutorial-handling-service-validation-errors-cairngorm/ http://jwopitz.wordpress.com/2008/04/25/tutorial-handling-service-validation-errors-cairngorm-part-2/ http://jwopitz.wordpress.com/2008/04/25/tutorial-handling-service-validation-errors-cairngorm-part-3/ --- In [email protected], "Ralf Bokelberg" <[EMAIL PROTECTED]> wrote: > > You could either set a bindable property on your model, > or pass in a object, which does the result handling. > > Cheers > Ralf. > > On Sat, Jun 28, 2008 at 8:09 PM, <[EMAIL PROTECTED]> wrote: > > You mean if i have to display an alert message 'Customer name already > > exists' them i have to put this code in result method as follows, Basically > > this is Command class which implements IResponder . > > > > public function result( event : Object ) : void > > { > > // Some processing > > Alert.show( 'Name XYZ Already Exists' ) ; > > CursorManager.removeBusyCursor(); > > Application.application.enabled =true ; > > } > > If you meant this then don't you think it is not good design , now suppose > > if instead of Alert message i am going to display inline error message on > > the view then i have to access view in my command class to display error > > message. > > , > > > > ----- Original Message ----- > > From: "Paul Andrews" <[EMAIL PROTECTED]> > > To: <[email protected]> > > Sent: Sat, 28 Jun 2008 19:00:07 +0100 > > Subject: Re: [flexcoders] synchronous events in flex > > > >> ----- Original Message ----- > >> From: <[EMAIL PROTECTED]> > >> To: <[email protected]> > >> Sent: Saturday, June 28, 2008 2:54 PM > >> Subject: [flexcoders] synchronous events in flex > >> > >> > >> > Hi > >> > Can anyone tell me how to write synchronous events in flex application? > >> > >> There are no synchronous events. > >> > >> > I am calling an Httpservice on focus out event of text field this > >> > service > >> > checks name duplication.
