Subject [SCXML] Memory leak, performance problem
Date Fri, 04 Aug 2006 13:16:10 GMT


we are working with SCXML extensively for quite a while. Its a great tool,
its saves a lot of development time and makes things easier. But there are
some impacts we discovered:

- After a period of time triggering a lof of events, that contain
assignments, variable creations and notifications of the EventDispatcher,
SCXML seems to loose memory.

- SCXML uses a lot of processor time, when large amounts of events with
conditions are compared. A way to improve performance could be to compile
JEXL expressions in TransitionTarget at load-time of the SCXML file.

- For each TransitionTarget, a JexlContext is created. For us, it is very
important to have one context with all variables that is valid for all
TransitionTargets. Is there a simple way to achieve this?
