Hi Andreas that worked perfectly! thanks! Just so that I understand the mechanism, basically I have to transit into the initial state child-state-A1 , and deep_history will know that it actually needs to go through child-state-A2 on its way there. correct? regards silva

Hi

...

the documentation shows how to do it with sc::transition... but I couldn't find a way to do it in the case of custom reactions trial and error didn't work either...

Did you try return transit< sc::deep_history< child-state-A1 > >() ? Regards, -- Andreas Huber

Hi

Question on using history with custom reactions

I have a parent-state-A state and a parent-state-B state

parent-state-A has a child-state-A1 and a child-state-A2 (nested state)

The machine initializes on parent-state-A entering by default in child-state-A1 (the initial state) Then moves to child-state-A2 Then to parent-state-B

Then a event occurs and I need the machine to go back to child-state-A2 (and not the initial state child-state-A2)

question is how do I do it when using custom reactions that is, instead of doing a hardcoded

parent-state-B::react (event& evty) {     return transit<child-state-A2 > (); }

I would like to do something like

parent-state-B::react (event& evty) {     return transit<parent-state-A > (); }

and let the state machine figure out that it needs to go back to child-state-A2 rather then the initial child-state-A1

the documentation shows how to do it with sc::transition... but I couldn't find a way to do it in the case of custom reactions trial and error didn't work either...

help! : )

thanks in advance silva
