Hi All

I have run it to a problem that feature : Event Hierarchy see doc : http://svn.boost.org/svn/boost/trunk/libs/msm/doc/HTML/ch03s02.html#d0e1108

Does not work in case of sub state machine with favor_compile_time policy. No trans get called on the sub state machine even it has a row with event type to the event base class.

This now hit me badly because compiler runs out of heap if favor_compile_time policy is not used but when it is used I can not dispatch based on base type and I have about 150 different event so declare a transition for it is a no go.

Is there any workaround for this problem ?.

Hi Richard, It took a while but I now committed a solution into the trunk (rev. 68194). Could you please give it a try? It passes my tests but double-checking cannot hurt. It's actually a complete reimplementation of the feature, without boost::any. The advantages: - it supports event hierarchy - it compiles slightly faster - it runs much faster - it requires no rtti I hope it solves your problem. Please let me know. It's not a major change so I could merge it into 1.46, but only if you manage to test it until Monday evening. Otherwise, you'll have to use the trunk version until 1.47. Regards, Christophe
