Do you really need to use Repeater? - Gordon ________________________________

I understand the asynchronous bit. Also, running the swf in debug mode shows that downloadedBytes == totalBytes, so I'm sure it's done loading. Plus, like I said, setting creationPolicy="queued" makes them show up (but not creationPolicy="all"). I'm pretty sure it's some kind of timing issue, like something to do with calling createComponentsFromDescriptors() before the databinding classes have updated the underlying dataprovider. But I might be talking out of my butt. There's a lot of "magic" going on here under the hood that I don't understand. --- In [email protected] <mailto:flexcoders%40yahoogroups.com> , "Alex Harui" <[EMAIL PROTECTED]> wrote: > > Yes, of course, but I'm not sure what's going on with repeater bindings > and async loading. > > > > ________________________________ > > From: [email protected] <mailto:flexcoders%40yahoogroups.com> [mailto:[email protected] <mailto:flexcoders%40yahoogroups.com> ] On > Behalf Of Gordon Smith > Sent: Thursday, June 14, 2007 12:54 PM > To: [email protected] <mailto:flexcoders%40yahoogroups.com> > Subject: RE: [flexcoders] Re: Help Request : Deferred Instantiation and > Bound SWFLoader > > > > I tested locally.
