Hello, I'm reading the Boost.Msm document. I found some mismatches between the document and the code. Here is the document. http://www.boost.org/doc/libs/1_46_1/libs/msm/doc/HTML/ch03s02.html Section:Explicit entry / entry and exit pseudo-state / fork State machine diagram "stm Fsm". I believe that the diagram should correspond to an example code below. http://www.boost.org/doc/libs/1_46_1/libs/msm/doc/HTML/examples/DirectEntryT... ==1== In the diggram, there are two transitions that are triggered with event5. But outer one is event6 in the code. 168: _row < SubFsm2::exit_pt 169: <SubFsm2_::PseudoExit1>, event6 , State2 > ==2== There is no transition in the diagram correspond to the code below. 167: _row < SubFsm2 , event1 , State1 >, ==3== There is no transition in the diagram correspond to the code below. 136: _row < SubState2 , event6 , SubState1 >, I'm not sure which is correct the code or the diagram. It's depends on what the author want to describe. Christophe, could you check that? Thanks, Takatoshi
