Hey! I've been using SCXML and it's really nice. I had some problems with timers though - I just couldn't quite do what I needed to do, so I wrote some extra scheduler classes. They turned out to be REALLY helpful so I thought I might contribute them back if you thought anyone else could use them.
I've never contributed to Apache Commons before so please bear with me if I am doing this all wrong. The classes I wrote were for replaying events and testability. I had a series of events and I wanted to replay them - this is great for unit testing and also let me change the state machine and replay the events and see what happened. But timers threw this off - if a timer started, I had no idea when in the sequence of following events the timer would trigger. Therefore one timer class I wrote is for replaying events - you have to tell the replay class what time it is supposed to be, and it'll fire off any timer events that should have fired. This let me take two or three days of things and replay them almost immediately, which gives me a lot of very useful abilities. I know when each event happened, so I can just register the time and fire the event and all timers behave just like they should. The other timer class I wrote just extended SimpleScheduler. I need reporting, and there are times when things are waiting on a timer to fire - but I can't tell that as I couldn't see what timers are present or when they'll fire. So I couldn't report on them, nor could I unit test this. So I wrote an extension of SimpleScheduler that just lets me see that information. SimpleScheduler uses a java timer class that ALSO doesn't let you see any of that information, thus I couldn't really do this quite the way I hoped, but every time you start a timer this just tracks when it will fire off and lets you query on it. Would these classes be suitable to share back? And if so I noticed that Apache Commons SCXML doesn't use JodaTime. I'm going to guess I need to rewrite the classes not to use JodaTime before submitting them, but I figured that was worth asking about!
