Hey Jeff, check out this other article. Might provide some ideas for you.

Steve,

Got a question – when sending an outgoing message from the gateway, how do i ensure that the message goes only to a specific client? In my situation, my flex app needs to receive messages of server actions completed, so its not two-way.

@Jeff Regan & @Gordon K
The error message you are getting from “it” is that you are missing a destination or the destination is incorrectly configured. Destinations are configured manually in the messaging-config.xml file.

Be aware :

x.headers['DSSubtopic'] = “simpleChat”;

DSSubtopic is case sensitive. You have to call it in this fashion or ColdFusion/Flex will upper case the header value and make it inaccessible.

I got mine to work. The error is gone. Im not 100% sure what I changed, but I was playing around in WEB_INF\flex\messaging_config.xml and I uncommented the property localhost. I did a few other things that I dont think were signficant. One was I defined my channel set in code instead of taking it from a config, meaning the app didnt need a services_config.xml reference in compiler settings. I also made a copy of the default destination and called it MyGateway, so I could customize settings.

I still have some issues left. I cant get subtopics to work (I had commented out subtopics to start with), and my recieveChat event on the flex side is getting called twice for every chat msg, not sure why.

But at least I am getting a round trip message and no error.

That’s exactly what I am getting with the SendgatewayMessage call.

Keep me posted on what you find from the CFLOG.

Jeff, I am working on the same thing and having exactly the same problem, using stock CF9 install with blaze ds. I added a sendGatewayMessage to the cfc and now the output count started incrementing on the cfgateway. However, still nothing coming back to flex. I tried taking out the subtopic stuff but that didnt help. I am going to add a CFLOG and see what I get.

I also failed to note that the webroot of the installation is htdocs in Apache web server.

In that last message the page edited out the “cfreturn x” CF tag.

It’s when I try to pass the message back to Flex from ColdFusion. The it is the message.

I’ve tried and SendGatewayMessage(“test”, x). Neither worked.

What is “it” in your last comment? Flex or ColdFusion?
