Not sure I understand...
Let me try to give an answer that might fit your question :
as soon as one session is created, and as soon as you don't have an executor in
the chian, then any message send by the client will be processed in the exact
order it has been sent. Ie, if a client sends 2 messages A and B, they will be
preocessed in teh same order, A then B.

No, you rarely need an executor filter.

That is what will happen, always.

Ensure sequential execution
I guys, I have the following Problem:
- I defined a Server to handle some Json Strings.
Acceptor a = new NioSocketAcceptor();
- I had some filters so:
a.getFilterChain().clear(); // I removed all filters
a.getFilterChain().addLast("jsonString", new ProtocolCodecFilter(...));
a.setHandler(myHandler);
I want to know, if in my case the newer event is not processed if the event
handler method for the older event for the same session hasn't returned yet?
Or I always need an Executor Filter?
In my requirement, I don't need parallel processing. I must wait that the event
handler complete executes before start to handle the new event.
Thanks
