Symptoms

Jelly scripts fail execution with error messages such as the following in the application logs:

2008-04-21 13:39:40,111 ERROR [web.action.util.JellyRunner] Could not run script.
org.apache.commons.jelly.JellyTagException: null:20:0: <jira:TransitionWorkflow> Invalid action name 'Open'.
at com.atlassian.jira.jelly.tag.issue.TransitionWorkflow.getActionByName(TransitionWorkflow.java:434)

Cause

The Jelly script is trying to perform an invalid workflow action on an issue as the associated workflow does not define such a step.

Resolution

Make sure the workflowAction attribute in the <jira:TransitionWorkflow> is a valid action for each and every issue the Jelly script will be applied to.
