問題文
A developer has an active workflow definition and needs to change it while the current version keeps running for users. Which statement describes workflow versions?
選択肢
- One version can be in development and one version can be active at the same time and a running instance carries on with the definition it started from.
- An inactive version can still start new instances so that a released change can be rolled back from the process of a page.
- Several versions can be active at the same time and the runtime engine picks the newest one for each new instance while the older ones stay available for the instances that are still running.
- An active version can be moved back to development so that the change is made in place and the instances that are running pick up the change at their next activity.
