Behavior of tasks completion when inside two or more ---------------------------------------------------- Key: JBPM-2528 URL: https://jira.jboss.org/jira/browse/JBPM-2528 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.1 Environment: - jBPM Version : 4.1 - Database : MySQL 5.1 - JDK : 1.6.0_15 - Container : java -version - Configuration : default jbpm.cfg.xml - Libraries : default librairies Reporter: Romain LM I do not understand the behavior of tasks completion when they are inside two or more forks. You will find the accurate questions in the test case comments.
