And I figured out the problem. The conversation becomes a long-running (non-temporary) conversation if there is a @Begin method. My @Begin method was returning a String. The method itself didn't do anything useful so I had it return null as the string. This does not work! That nukes the conversation. I'm not sure what it should return if the return type is String, but when I set the return type to void, everything worked.
There are many subtle gotchas in this that are hard to debug. I need to put together some notes maybe.
