Hi,

The UML 2.0 Superstructure Specification is quite clear in stating that an internal transition executes without exiting or re-entering the state in which it is defined (and therefore the entry/exit actions of that state are not executed).

In the specification I could not find however what happens to the nested states of that state. Suppose a state A has a substate A1 and an internal transition defined in state A executes, are the entry/exit actions on state A1 then executed ?

Best regards,

Jos
