JMWE shows an error message on the issue view if any error occurs during the execution of the post-function. This message is displayed only if the current user is a Jira administrator.

  • Return "parent-child" for cascading custom fields: This option is applicable for the Select list (cascading) custom fields. If you select the Return "parent-child" for cascading custom fields option, values from both the parent and child lists are copied into the destination field. For examplea custom cascading field has the values A and 1 in the parent and its child lists respectively. When this field is copied into a text field

    • without the option, the value 1 is copied into the text field 

    • with the option, the value A - 1 is copied into the text field.

  • Copy only if not set: Copies the value(s) of the From field to the To field of the current issue, only when the To field is empty on the current issue.

  • Create missing value(s): Allows creating any missing Component/s or Version/s while setting or copying a field that expects Versions or Components. Note this is applicable for version and component fields.

  • Ignore empty value: Will not set (clear) the destination field of the current issue, if the value of the source field is empty or null.

  • Add value(s) to the destination field: Appends the value(s) of the selected From field to the To field of the current issue. This is applicable only to multi-valued fields.

  • Send notifications: Jira sends notifications for the change in the selected To field value on the current issue. You can control the default value of the "Send notifications" option in the Configuration page under JMWE administration. Click here for more information.

Consider a use case where you want to set the components of an issue with a value selected from a cascading field that carries the Main and Sub-components in parent and child. To configure this:

  • Add the Copy value from field to field post-function to the Create transition of the issue workflow.

  • Select the Cascading field as the From field.

  • Select the Components field as the To field.

  • Select Return "parent - child" for cascading custom fields option.

Note: The Component name should be in Component - Subcomponent format.
