Use case

Create a hierarchy of issues by prioritizing them via a Number Field and a couple of post functions in the Create transition and a global reflexive transition that will update the hierarchy after a new value has been modified or introduced.


Prerequisites

Remove this section, if no prerequisites are needed.


Create a custom Number Field called Customer Prioritization and add it to the Create/View/Edit screens.


Create a new global reflexive transition (from any issues to itself) and add it a custom screen that includes the Customer Prioritization field.






Configuration




Add an Update or copy field values post function to the Create transition in the second position.


Target issue*

Select Set target issues manually (parser expression) and add the following expression:

issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + {issue.cfCusPrio} + " order by \"Customer Prioritization\" ASC")


This expression will select all of the existing issues whose Customer Prioritization field value is greater than or equal to the existing one excluding the one from the current issue.



Field*

Select the Customer Prioritization field and add the following expression.

{nnnnn} + indexOf(^%{00015}, issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + {issue.cfCusPrio} + " order by \"Customer Prioritization\" ASC"))


This expression will add to the number introduced in the screen for Customer Prioritization the index of the issues in the issue list obtained before in every of the issues according to the issue list in the Target issue field.



Conditional execution


%{nnnnn} !=  null


The post function will only be executed if the field has a value.







Add an Update or copy field values post function to global reflexive transition previously created.


Target issue*

Select Set target issues manually (parser expression) and add the following expression:

(previousValue({issue.cfCusPrio}) = null ? issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + {nnnnn} + " order by \"Customer Prioritization\" ASC") : ({issue.cfCusPrio} < previousValue({issue.cfCusPrio}) ? issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + {issue.cfCusPrio} + " and \"Customer Prioritization\" <= " + previousValue({issue.cfCusPrio}) + " order by \"Customer Prioritization\" ASC") : issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + previousValue({issue.cfCusPrio}) + " and \"Customer Prioritization\" <= " + {issue.cfCusPrio} + " order by \"Customer Prioritization\" DESC")))


This expression will cover three possible situations:

Case 1 - There was no previous value in the custom field Customer Prioritization: The expression will fetch the issues as in the create transition.
Case 2 - The value entered in the custom field Customer Prioritization is smaller than the previous value: The expression will fetch all issues whose Customer Prioritization value is greater than or equal to the entered value and smaller than or equal to the previous value in an ascending order.
Case 3 - The entered value is greater than the previous value: The expression will fetch all issues whose Customer Prioritization value is greater than or equal to the previous value and less than or equal to the entered value in a descending order.



Field*

Select the Customer Prioritization field and add the following expression.

(previousValue({issue.cfCusPrio}) = null ? {issue.cfCusPrio} + indexOf(^%{00015}, issuesFromJQL("issuekey != " + %{00015} + " and \"Customer Prioritization\" >= " + {issue.cfCusPrio} + " order by \"Customer Prioritization\"")) : ({issue.cfCusPrio} < previousValue({issue.cfCusPrio}) ? ^{issue.cfCusPrio} + 1 : ^{issue.cfCusPrio} - 1))


Depending on the previous cases, a number will be added or deducted from the Customer Prioritization value of each issue of the issue list.
