Quite possibly not. While I'm a reasonably experienced web programmer, I'm completely new to Flex, so if there's a better or more standard way of doing what I'm trying to do, I'm all for it.
What I actually need is to take a dynamically generated list of filenames (populated via RemoteObject), and load an external swf file for each one into a view stack. I'm using Cairngorm 2.2, so - as I understand it - manipulating the view (ViewStack) directly in my Command class is a no-no. I'm just supposed to update the model and let the data-bindings update the view. The Repeater was the simplest way I could think of to do that, but I'm not married to the construct in the least. Is there a better way to do it? --- In [email protected], "Gordon Smith" <[EMAIL PROTECTED]> wrote: > > Do you really need to use Repeater? > > - Gordon > > ________________________________ > > From: [email protected] [mailto:[EMAIL PROTECTED] On > Behalf Of ibid049 > Sent: Thursday, June 14, 2007 1:30 PM > To: [email protected] > Subject: [flexcoders] Re: Help Request : Deferred Instantiation and > Bound SWFLoader > > > > Yes, these are still not showing up long after the time it would take > to get them from the server.
