Thanks for the idea, sounds good. I did something a bit different. I used the same pattern as the demuxingIoFilter by implementing a strategy factory IoFilter which delegates processing to the appropriate "IoFilter" (a custom class with a method called handle(message) in my case! :.) according to the received message type. So far, it works pretty well. I guess that instead of delegating the processing to a single custom filter according to type, I could delegate to a chain of filters according to type! Maybe as a further enhancement...

Was distracted by many things. :) For now we don't provide such a feature due to its implementation complexity and possible confusion. What do you think about inserting four custom filters? msg - transform a1 - transform b1 - transform a2 - transform b2 - transform 3 You could program the transforming filters to ignore messages which is not relevant to it. For example, 'transform a1' and 'transform a2' could ignore the message type B and just forward them to the next filter. How does it sound?
