Features used to implement the example
Example: Transition only a sub-task among several ones
Could you please advise how I can transit only first sub-task on parent issue transition.
It will require JIRA Workflow Toolbox 2.1.28 or higher. It can be done using 3 post-functions:
Copy a parsed text to a field post-function to write the name of a transition into virtual field "Ephemeral string 1" virtual field. In this example I use transition "Start Progress":
Copy a parsed text to a field post-function to write the issue key of first sub-task order by a certain field into virtual field "Ephemeral string 2". In this example I order sub-tasks by creation date-time in ascending order:
Note that:
- Text to be parsed is:
toString(first(sort(subtasks(), {00009}, ASC)))
- {00009} is code for numeric value of field "Date and time of creation"
- We are using advanced parsing mode
Write field on issues returned by JQL query or issue list post-function for copying the name of the transition in "Ephemeral field 1" into virtual field "Execute transition" of issue whose key is in "Ephemeral field 2":
Note that:
- %{00062} is field code for "Ephemeral string 2"
- JQL query used is:
issuekey in ("%{00062}")
Once transition is configured, it will look like this:
