Features used to implement the example

• Read fields from linked issues or sub-tasks

Example: Propagate highest priority from blocked issues to blocking issues

We want that current issue inherits the highest priority among those issues being blocked by her. Issues blocked by current issue are those issues linked (directly or transitively) to current issue using an "is blocked by" issue link, that is:

• current issue blocks another issue

• another issue is blocked by current issue

We insert post-function Read fields from linked issues or sub-tasks in "Create Issue" transition for setting current issue's priority using linked issues priority.

We can also include this post-function in other transitions of the workflow, in order to refresh the priority in any other moment of life cycle of the issue.
