In the attached project are two portlets. The first portlet (counting portlet) consists of a counter and a button that increases the counter. The second portlet (publishing portlet) consists of a button that publishes an event that is processed by the counting portlet an increases the counter too.

The bug appears if you click on the publishing button twice. Don't click on the Count-Button in the first portlet before. If you do this the bug does not appear.
