[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-1162) Problem with exception handling within the Decision nodes

Problem with exception handling within the Decision nodes --------------------------------------------------------- Key: JBPM-1162 URL: https://jira.jboss.org/jira/browse/JBPM-1162 Project: jBPM Issue Type: Bug Components: Runtime Engine Affects Versions: jBPM 3.2.2 Environment: Vaio laptop running Windows Vista, Java 1.5, JBPM 3.2.2 Reporter: Jon Folland Assignee: Alejandro Guizar Fix For: jBPM 3.2.10 Original Estimate: 0 minutes Remaining Estimate: 0 minutes I believe there may be a bug in the Decision class where exception handling is concerned which causes this failure: If the line: String transitionName = decisionHandler.decide(executionContext); ... ...in the method public void execute(ExecutionContext executionContext) throws an exception, which is caught here in the same method: raiseException(exception, executionContext); We miss the block: if (transition==null) { transition = getDefaultLeavingTransition(); log.debug("decision didn't select transition, taking default "+transition); } So when executionContext.leaveNode(transition); is called at the bottom, there wil be no transition set. I believe we need to check for a tranistion==null condition regardless of whether an excpetion has been handled. Otherwise you will never be able to handle an exception in a Decision without another unhandled exception being thrown (which kind of defeits the point :-)
