Re: Any recursive composition sample?
Thanks for volunteering! The Spring container that Ken is working on will demonstrate how composites function. However, just to be accurate, we do not have *any* samples in core2 yet - it's not just a question about recursion. If people want to develop them and help out that would be greatly appreciated. The reason we don't have them is because when I develop code I prefer writing test cases and using those instead. It's great if people want to volunteer their effort to create samples though.

Re: Any recursive composition sample?
Yea that sounds good in terms of the really simple samples. I'd like to have a "slim" BigBank that just shows SCA though since I think it is important that people realize they can pick and choose technologies. I probably imagine SDO and DAS would say the same thing about SCA too.

You may have a point that this is too much for one sample, but generally these three technologies look in the minds of people to be sort of separate and I still like the idea of a sample that shows them all coming together.

For me, the value in SCA is around assembly, policies and conversations, so "showcase" features could be: - dynamic re-wiring - switching transport protocols - conversations and non-blocking/async behavior - introduction of policy I think we'll want to show both composites being used as components and using composites through inclusion (aka fragments). I also think we need to eventually start showing some more examples with some interesting complex properties being set.
