Warning: Injector already has a rule for type

I have a bunch of warning messages like this appear when using Robotlegs/Signals. Everytime this command class executes, which is every 2-3 seconds ..this message displays below

If you have overwritten this mapping intentionally you can use "injector.unmap()" prior to your replacement mapping in order to avoid seeing this message. Warning: Injector already has a rule for type "mx.messaging.messages::IMessage", named "".

The command functions fine otherwise but I think I'm doing something wrong anyhow.

public class MessageReceivedCommand extends SignalCommand

    public var message:IMessage;

        ...etc.. do something with message..

the application context doesnt map IMessage to this command, as I only see an option to mapSignalClass , besides the payload is received fine.

Wonder if anyone knows how I might either fix or suppress this message. I've tried calling this as the warning suggests

injector.unmap(IMessage, "")
but I receive an error - no mapping found for ::IMessage named "".

    Sorry for the late response, I was away over the weekend.

    -Could you post the code for the mappings?

    -Could it be that you’re using an older version of the SignalCommandMap? I’m not sure, but the warning you’re getting was reported by other users too, and it might be related to a bug in older versions?
