Winson, thanks for filing the blueprint: https://blueprints.launchpad.net/mistral/+spec/mistral-global-context, some clarification questions: 1) how exactly would the user describe these global variables syntactically? In DSL? What can we use as syntax? In the initial workflow input? 2) what is the visibility scope: this and child workflows, or "truly global”? 3) What are the good default behavior? Let’s detail it a bit more. DZ> -------------- next part -------------- An HTML attachment was scrubbed...
