When you add this post-function to a transition and trigger it, the add-on sets the Entity property of the selected entity to the specified value. The value can be either a:
- Raw Value, when you select
Constant or Groovy Template as the Value type. The value should be a valid JSON string, and you can use Groovy Template markup to insert dynamic content.
- Result of a Groovy expression, when you select Groovy expression as the
. The value should be a Groovy expression that returns a valid JSON string.
See the Expected Value tab of the
Groovy help editor or refer to the documentation to know more about the expected value in the above cases.
- Set only if property is empty
Sets the property value only if the property is currently empty.
Will not set (clear) the selected property, if the value is empty or null.
To execute this post-function based on the result of a groovy expression see Conditional execution/validation using a Groovy expression.
By default, all errors (Java Exceptions) raised by this post-function, including those raised by custom Groovy scripts, will be logged in the JIRA log file but will not be reported to the user and will not prevent the transition from completing.
However, when designing new workflows or troubleshooting them, it is more convenient to be notified immediately of any such error during the execution of the transition. On development and staging Jira instances, you can activate error reporting for all JMWE post-functions on the JMWE configuration page, and it is recommended to do so. But on production Jira instances, you might want to show errors only for the post-function(s) being worked on, in order to avoid disrupting other workflows. To make errors raised by the current post-function prevent the transition from completing and show the error in the browser, select
Make transition fail when an error occurs in this post-function.
