Using ColdFusion and LCDS in AIR-powered Flex Applications

Previously, I've discussed how to use ColdFusion Components (CFCs) in AIR-powered Flex applications but I never got a chance to follow up on how to use CF8's integrated LiveCycle Data Services ES in AIR.

I've figured out that all I need to do is specify a ChannelSet component that is reused in both the Consumer and Producer. Since I was developing locally, I set up my AMFChannel to use my local server. You can see in the following example:

<!-- when developing a Flex web app, this is not required but we need this now that we are on AIR --> <mx:ChannelSet id="channelSet"> <mx:channels> <mx:AMFChannel uri="http://localhost:8500/flex2gateway/cfamfpolling" pollingEnabled="true" pollingInterval="3000"> <mx:id>cf-polling-amf</mx:id> </mx:AMFChannel> </mx:channels> </mx:ChannelSet> <!--- consumer handles any broadcasted messages from either a client or the server ---> <mx:Consumer id="consumer" destination="ColdFusionGateway" channelSet="{channelSet}" /> <!--- producer handles creating a message to broadcast from a client to all subscribed clients ---> <mx:Producer id="producer" destination="ColdFusionGateway" channelSet="{channelSet}" />

I know there are other channels, such as RTMP, but I have not used them yet. Since I was learning how to use CF/LCDS in AIR, I used it in an AIR version of a simple Chat application. I was quite impressed how easy this was to do. By simply setting up the ChannelSet, I had a working LCDS powered AIR application.
