Hi Kevin, DataService exposes a bindable 'connected' property that lets you know whether its underlying channel to the server is up or not. If it's not up, DataService will attempt to reconnect indefinitely. You should watch the 'connected' property and let the user know when they've lost connectivity, as well as when connectivity is regained.
DataService also provides a disconnect() method that can be used to shut down the instance, and will also stop any further automatic reconnect attempts. Hope that helps, Seth ________________________________________ From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Kevin Sent: Thursday, January 24, 2008 9:07 AM To: flexcoders@yahoogroups.com Subject: [flexcoders] Re: LCDS Paging error and connection management in DataServices. Advice? I'll add to this post, how do you check the connected status if you are using amf-polling?? If I turn off my internet connection while working, I get tons of errors when trying to navigate the app since things are all of a sudden not loading in via paging... I am not sure the best way to handle this. - Kevin --- In flexcoders@yahoogroups.com, "Kevin" <[EMAIL PROTECTED]> wrote: > > I am trying to handle a situation where my user are getting > temporarily disconnected from my web app and then proceeding to > continue enter info thinking that it is being saved simply because it > is still working in actionscript.
