I was working on combining nested node and transition based executions in a same process:
I successfully managed to insert a nested node based sequence between two activities (that ends up in a 3 activities relied by 2 transitions).
I'm thinking on the other way around: to add an activity transitions sequence inside one of the nested nodes but I cannot figure it out how to handle that.
As a nested node returns to its parent when completed, there is no way to start a transition based sequence before this operation.
I think this use case could be useful in some situations: i.e a split in which each branch must be handled in a predefined order but the internal behaviour of each nested node is transition based.
I will make a try by creating childExecutions at nested node level...
May be the returnSignal operation for nested nodes should be optional ?
