Hi Seth,
Sorry to bother you again... how to get the channel sets before
connecting? This is what I'm trying to do:
_remoteObject = new RemoteObject();
_remoteObject.destination = remoteObjectDestination;
var cs:ChannelSet =
ServerConfig.getChannelSet(remoteObjectDestination);
cs.channels.forEach(
function(channel:*, index:uint, array:Array):void
{
Channel(channel).uri.replace("{context.root}",
contextRoot);
});
This approach does not work, all the channels from the channel set are
marked as "undefined". remoteObjectDestination and contextRoot are both
String properties.
Thanks, Robert
