Hi, Anthony,
The MDT UML2 project's code generation is only roughly equivalent to the
class diagramming subset of UML. It will generate the structure of
classes, but there is no support for generating behaviour except
inasmuch as in can be specified as OCL or Java-snippet annotations.
If you are using MDT UML2 only, then you will get a Java class (and an
Ecore EClass) generated for your state machine only because a UML state
machine is a kind of class. But the code that is generated will be as
meaningless as the class structure of any state machine.
If you are using some tool that purports to generate behaviour from
state machines, then this is not the right newsgroup.
HTH,
Christian
