Flex RemoteObject Intermittently Failing to Invoke CFC

Question

I have a Flex app that uses Flash Remoting and the RemoteObject to pull data from a ColdFusion CFC. About 75% of the time it works, but the other times I get a message using Charles (a debugging tool) that says faultString = "Unable to Invoke CFC". FaultCode = "Server.Processing".

Here's my RemoteObject:

<mx:RemoteObject id="carsSvc" destination="ColdFusion" source="ca.sqmIDash.cfc.sqmIdash">
   <mx:method name="getCARs" result="resultHandler(event)"/>
</mx:RemoteObject>

The server set up on our web farm is to use load balancing. I'm not sure if this is causing the problem or not. Probably not, but it's a thought.

Any help is appreciated!!

Answer 1

It sounds to me like you're having server issues completely independent of Flex. I'd look into the load balancer and/or what the machine re doing that 25% of the time you're receiving the error.

I'd also add some error checking on the server to e-mail you the relevant errors. ( Perhaps in the onError Application.cfc ) That may help you diagnose if there is a bug in your server side code.

I do not see a RemoteObject in your question, even though you have a line that says "here is my RemoteObject"

Answer 2

I tried to put the remote object in but the site didnt' show the code at first. ---Justin
