hasChanged()

This function returns true only if the field has changed in the current transition.

The function hasChanged(field_code) is used when we set a validation that is incompatible with a condition in the same transition, typically when validating a value entered in the transition screen. When Jira evaluates the validations in a transition, it also reevaluates the conditions, and if they are not satisfied an Action X is invalid error message is shown and the transition is not executed.

Syntax

hasChanged(%{nnnnn}) #Output: Boolean

Examples

Parser expression Description

hasChanged(%{00012})

We have a boolean condition {00012} = null (i.e., Due date = null) in a transition, so that it's only shown when Due date is empty. This transition also has a transition screen containing field Due date, and a boolean validation {00012} != null, in order to make Due date required in the transition.
The configuration described above will not work since both the condition and validation are mutually incompatible. We can fix it replacing the boolean condition with {00012} = null OR hasChanged(%{00012}).
