Yup thats the way to go and then you can have another variable in your ModelLocator for the currentstate and set it once the remote call is complete to change the state of the view, which u bind to. Dimitrios Gianninas RIA Developer Optimal Payments Inc.

Like 1) Upload file and related data, 2) Preview Results 3) Approve. My view needs to know when the form submission has succeeded and then trigger the next appropriate step. Per the docs, it seems that the Command classes can implement Iresponder - perhaps that is the way to go.

Bind the variable of the model to a view stack that monitors changes to the model. Upon successful form submission and return from the server, update the model variable, the view will then change to show the view stack current view: Some ruff code: private function getView( state : String ) : Container { if( model.workflowState == ModelLocator.STATE_FORM ){ return formview; } else if (model.workflowState == ModelLocator.STATE_RESULTS){ return resultview } else { return defaultview; } } <mx:ViewStack selectedChild="{getView(model.workflowState)}"> <mx:Canvas id="formtview" width="100%" height="100%"/> <mx:Canvas id="resultview" width="100%" height="100%"/> <mx:Canvas id="defaultview" width="100%" height="100%"/> </mx:ViewStack> Take a look at this post by Alex Uhlmann for full example: http://weblogs.macromedia.com/auhlmann/archives/2006/07/cairngorm_2_for_ <http://weblogs.macromedia.com/auhlmann/archives/2006/07/cairngorm_2_for_> 1.cfm Michael Ritchie AOL Xdrive --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Battershall, Jeff" <[EMAIL PROTECTED]> wrote: > > I've got an app consisting of several discrete views (MXML components) > performing different admin functions. > > One of the components has the user submit a form, after which I'm > going to have the user review the results before finalizing > (approving) the submission. > > I'm interested in anyone's feedback on the best way to approach this. > If I fire off a Cairngorm Event/Command to do the submission, how do I > return control back to the view that fired the event after the > submission is complete so that it can perform the next step in the > process (approval)?
