[JBoss JIRA] Created: (JBPM-1775) verify if collection exceptionHandlers can be loaded lazy

by Tom Baeyens (JIRA)

verify if collection exceptionHandlers can be loaded lazy --------------------------------------------------------- Key: JBPM-1775 URL: https://jira.jboss.org/jira/browse/JBPM-1775 Project: JBoss jBPM Issue Type: Task Security Level: Public (Everyone can see) Reporter: Tom Baeyens Fix For: jBPM 3.3.1 GA >From Martin Putz: " A quick test showed that setting all those relations to lazy="true" cuts down the number of executed SQL selects quite drastically. I don't see any negative side effects of changing these settings, but I'm curious about the reasons why lazy="false" is chosen as default. Especially as I don't see a lot of our customers using exception handlers (or at least they don't report it).

[JBoss JIRA] Created: (JBPM-1164) Null Pointer Exception is thrown when subprocess is leave event is fired.

by Gurpreet Sahota (JIRA)

Null Pointer Exception is thrown when subprocess is leave event is fired. ------------------------------------------------------------------------- Key: JBPM-1164 URL: http://jira.jboss.com/jira/browse/JBPM-1164 Project: JBoss jBPM Issue Type: Bug Affects Versions: jBPM jPDL 3.2.2 Environment: Windows XP Pro, Sun JDK 1.5.0_13 Reporter: Gurpreet Sahota Assigned To: Tom Baeyens I have a process flow where process (A) calls a process state that in turn calls subprocess (B). When Subprocess "end" state is signalled then I receive a Null Pointer Exception. Following is stack trace java.lang.NullPointerException at org.jbpm.graph.node.ProcessState.leave(ProcessState.java:204) at org.jbpm.graph.exe.Token.signal(Token.java:195) at org.jbpm.graph.exe.Token.signal(Token.java:140) When debugging, it turns out that "leave" method in ProcessState tries to retrieve subProcessInstance from execution context. This is set to null causing exception. If executionContext.getToken() is used to retrieve the subProcessInstance, then it is not null. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

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

by Jon Folland (JIRA)

Problem with exception handling within the Decision nodes --------------------------------------------------------- Key: JBPM-1162 URL: http://jira.jboss.com/jira/browse/JBPM-1162 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: Vaio laptop running Windows Vista, Java 1.5, JBPM 3.2.2 Reporter: Jon Folland Assigned To: Tom Baeyens 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 :-) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-1158) Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml

by Julien Kronegg (JIRA)

Missing query JobSession.findJobsWithOverdueLockTime in hibernate.queries.hbm.xml --------------------------------------------------------------------------------- Key: JBPM-1158 URL: http://jira.jboss.com/jira/browse/JBPM-1158 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM jPDL 3.2.2 Environment: zip file downloaded from http://www.jboss.org/downloading/?projectId=jbossjbpm&url=http://download... Reporter: Julien Kronegg Assigned To: Tom Baeyens The org.jbpm.db.JobSession class has a findJobsWithOverdueLockTime(Date) method which use a query named "JobSession.findJobsWithOverdueLockTime". In similar methods of the same class, the queries are located in org.jbpm.db.hibernate.queries.hbm.xml, which is not the case for this query. The "JobSession.findJobsWithOverdueLockTime" string could not be found elsewhere in the project. Conclusion: the "JobSession.findJobsWithOverdueLockTime" query seems to be missing in hibernate.queries.hbm.xml (or the method should be removed from the class). -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
