All child tokens, when they're done, should/could transition to a join. The join will count down the outstanding tokens for the parent token, and allow it to resume when the last child completes. To avoid other potential problems, I suggest that you make your token-generating node a fork. I believe that there's a race condition leading to Hibernate StaleObject exceptions in join. Before you go into production, be sure to do some concurrency testing on join. -Ed Staub View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071960#...
