Hi, I'm trying to define a submachine without the BOOST_MSM_EUML_DECLARE_STATE_MACHINE macro (the "old" way - like in http://www.boost.org/doc/libs/1_46_0/libs/msm/doc/HTML/examples/SimpleTutori...). The "main" machine works as expected. However, the submachine doesn't kick in at all (the system asserts in default no-transition handler). Any ideas?
