That's a pretty common request, see item 3 on the to-do list:

http://www.boost.org/libs/statechart/doc/future_and_history.html#ToDoList

As stated in the todo-item, passing event data to the state constructor is 
not as straight-forward as it might seem. You are bound to lose event 
type-safety. However, if you have a compelling use-case, I'm willing to 
finally implement this feature.
