OSWorkflow supports no transition to another step on a transition for common and global actions (http://wiki.opensymphony.com/display/WF/3.3+Common+and+Global+Actions).

However, it isn't working for me in JIRA. Either there is a bug in Jira, in OSWorkflow, or I'm doing something wrong.

When I try this in a workflow imported into JIRA I get the following in the tomcat log file when I attempt to run the
transition:
