ūüöĬ†JWT 3.0 is out¬†ūüöĬ†

The app was completely overhauled, and so was the documentation: Jira Workflow Toolbox (Server/Data Center) Home

The page you are viewing is still valid for all app versions prior to 3.0.

Features used to implement the example


This example is considered outdated. Please head over to the one using our Transition issues post function here.

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:


Text to be parsed is: toString(first(sort(subtasks(), {00009}, ASC)))


Note that:

  • {00009}¬†is code for numeric value of field "Date and time of creation"
  • We are using¬†advanced¬†parsing mode


Update issue fields 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":


Text to be parsed is: issuekey in ("%{00062}")


Note that:

  • %{00062}¬†is field code for "Ephemeral string 2"


Once transition is configured, it will look like this:
