JWT is capable of processing values from multiple sources (e.g. issues, custom fields etc.). These sources are called seeds.
The following seeds are available:
- Seed issues: All issues that are found or returned by an issue list
- Seed strings: Strings, or texts, that are usually returned by a text list (e.g. custom field option list, list of components etc.)
- Seed numbers: Fixed numbers or numbers returned by a calculation
If values from a seed source are needed to perform actions, the field codes need to be precedented with ^
or the word seed
.
Code Block | ||||
---|---|---|---|---|
| ||||
%{seed.issue.summary} # is the same as
^%{issue.summary} |
JWT iterates over each seed and performs an action based on the values being found or specified. Whatever function or action you specify will be performed for each seed JWT recognizes.
Hier wäre doch ein Screencast wunderbar "Seeds in 60 seconds" - Oder erklärende Grafiken
Examples: to be linked and created
...
Probably most of the time, doing things with the help of JWT is related to a single object - the issue currently being transitioned, e.g. by adding a comment, updating a field, sending an email, etc. Referring to the current issue's information can be done by using a simple |
...
field code like |
...
However, since you can also use more complex functions in JWT that work with multiple objects, this simple notation is not sufficient for those use cases. To name a few examples
Whenever Jira Workflow Toolbox has to handle (or iterates over) multiple elements of |
...
Lists (or sources), those elements are referred to as seeds. Depending on the type of list, those are referred to as

Seed issues
Issue lists can be specified by JQL queries, issue list expressions, or (in some post functions or automation actions)
...
by predefined selections, e.g. Issues under Epic.

You might face seed issues when trying to

create/update/transition multiple issues.
- Create issue post function
...
Number of issues to be created | Mode | Description |
---|---|---|
Multiple issues |
...
JQL | An issue is created for every issue returned by the JQL query. | |
Multiple issues |
...
Issue list | An issue is created for every issue returned by the issue list expression. |
...
Example: You want to create multiple issue based on a a custom JQL that returns three issues:
- DEMO-1 Issue A
- DEMO-2 Issue B
- DEMO-3 Issue C
Creating issues based on this JQL query, the post function will run three times, where the following values will be returned throughout those three runs
Run | %{seed.issue.key} | %{seed.issue.summary} |
---|
...
1 | DEMO-1 | Issue A |
2 | DEMO-2 | Issue B |
3 | DEMO-3 | Issue C |
In general, using the seed notation, the nth run returns the field values of the nth issue from this list.
...
When choosing the Issue list mode, e.g.
...
with an expression like linkedIssues()

, the behavior is the same

Expression parser functions
List functions like mathOnIssueList() or textOnIssueList()

Seed texts
Text lists can either be
- static, e.g.
["firstElement", "secondElement", "thirdElement"]
, or - composed dynamically
...
- by using the toStringList() expression parser functions, e.g.
toStringList(%{issue.components})
ortoStringList(%{issue.
...
cf12345}})
(where the custom field with the ID 123456 is a multi option custom field) or- calculated by using one of the functions that return a text list like fieldHistory(), groupsUserBelongsTo() etc., e.g.
fieldHistory(%{issue.summary}})
orgroupsUserBelongsTo(%{system.currentUser}})

Multiple issues |

Text list | An issue is created for each element of a text list. |
Given the example of a static list above, the post function will run three times and the following values will be returned throughout those three runs
Run | %{seed.text} |
---|
...
1 | firstElement |
2 | secondElement |
3 | thirdElement |
Given a dynamic example, having selected the components Frontend and Backend on an issue, the post function will run two times returning the following values for each run
Run | %{seed.text} |
---|
...
1 | Frontend |
2 | Backend |
After adding a third component Interface, the post function will run three times returning the following values for each run
Run | %{seed.text} |
---|
...
1 | Frontend |
2 | Backend |
3 | Interface |

Transition issues post function or Transition issue action
According to this scenario, composing a summary with an expression like
Code Block | ||||
---|---|---|---|---|
| ||||
"Summary of " + %{seed.text} + " Issue" |
will result in three issues, named
- Summary of Frontend Issue
- Summary of Backend Issue
- Summary of Interface Issue
...
tbd.
Examples
Seed numbers
Number lists can either be
- static, e.g.
[1, 2, 3]
, or - composed dynamically by using the toNumberList() expression parser function
...
- or
- calculated by using one of the functions that return a number list like releaseDates(), timesOfTransition(), etc.

- , e.g
...
- .
releaseDates(%{issue.fixVersions})
ortimesOfTransition("Done","Open"})

in order to create three issues, the following values will be returned for each run
