Directed entry to specific sub-state of nested machine

[aplotskin]

@ekigwana thank you again. My Composite is actually pretty complex and is a History state, so does not have a normal initial entry path. So I was hoping this part of the UML state machine language was supported in SML. Seems like not.

I may be able to refactor my Composite into two pieces where this directed-to state is the initial state of a piece of it.

What you need is an arrow from State 1 -> Composite. If the desired initial state is Sub2 and it makes sense, then make that the initial state. State 1 -> Composite, region 1 kicks off its initial state, region 2 -> Sub1

See https://boost-ext.github.io/sml/examples.html#composite

Thank you, appreciate the reply and I see how my grabbing of that particular picture caused confusion. I only used that picture to show a directed transition example. My system is more complex, with a default initial state in Composite that is different from the one I want a particular upper state and event to transition into.

Then what you need is a Sub0 state which auto transitions to Sub1 or Sub2 as you desire.
