[JBoss JIRA] Resolved: (JBPM-508) create eclipse installation script for the labs

[JBoss JIRA] Resolved: (JBPM-445) getActorId in ProcessLog broken

by Thomas Diesler (JIRA)

[ http://jira.jboss.com/jira/browse/JBPM-445?page=all ] Thomas Diesler resolved JBPM-445. --------------------------------- Resolution: Out of Date > getActorId in ProcessLog broken > ------------------------------- > > Key: JBPM-445 > URL: http://jira.jboss.com/jira/browse/JBPM-445 > Project: JBoss jBPM > Issue Type: Bug > Components: Core Engine > Affects Versions: jBPM 3.0.1, jBPM 3.0.2, jBPM 3.1 alpha 2 > Reporter: michael lawley > Assigned To: Tom Baeyens > > ProcessLog.getActorId() always delegates to its parent (if any) and the comment says that getActorId is overridden in AuthenticationLog. However there is no AuthenticationLog and there is no subclass of ProcessLog that overrides getActorId so this method _always_ returns null. > Perhaps a better approach would be to grav the actorId using Authentication.getAuthenticatedActorId(); in the ProcessLog constructor. Naturally this would require adding a new instance variable to ProcessLog. -- 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] Resolved: (JBPM-453) Refactor Timer.getException() to return an Exception

by Thomas Diesler (JIRA)

[ http://jira.jboss.com/jira/browse/JBPM-453?page=all ] Thomas Diesler resolved JBPM-453. --------------------------------- Resolution: Out of Date > Refactor Timer.getException() to return an Exception > ---------------------------------------------------- > > Key: JBPM-453 > URL: http://jira.jboss.com/jira/browse/JBPM-453 > Project: JBoss jBPM > Issue Type: Feature Request > Components: Core Engine > Affects Versions: jBPM 3.0.1 > Reporter: Rainer Alfoeldi > Assigned To: Tom Baeyens > > If an Exception occurs during the execution of a Timer the first 4000 characters of the DelegationException.printStackTrace() output is saved and the Exception itself is disgarded. > Is it possible to extend Timer to return the caught Exception? The getException() will probably have to stay unchanged, but a new method would be very welcome. > The background for this request is if error handling is done outside of the Timer / jBPM Workflow execution there is no way of securely finding out what really caused the problem. The root cause MIGHT be mentioned in the first 4000 characters but that is not sure. And even if it is mentioned you would have to start parsing the returned String. StackTraces differ from JVM to JVM etc. etc. Not a fun thing to do. -- 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] Resolved: (JBPM-455) NullPointerException when subprocess starts or ends

by Thomas Diesler (JIRA)

[ http://jira.jboss.com/jira/browse/JBPM-455?page=all ] Thomas Diesler resolved JBPM-455. --------------------------------- Resolution: Out of Date > NullPointerException when subprocess starts or ends > --------------------------------------------------- > > Key: JBPM-455 > URL: http://jira.jboss.com/jira/browse/JBPM-455 > Project: JBoss jBPM > Issue Type: Bug > Components: Core Engine > Reporter: Eduardo Jimenez > Assigned To: Tom Baeyens > > Imagine a scenario where process A calls process B. Process A provides "in" parameters for process B through "read" access variables, and "out" parameters through "write" access variables. > Now imagine one of the "out" parameters is optional, say a failure code for instance (say documentation submitted with an application was imcomplete, the code indicates what part of the application was unacceptable). It might be set by process B or it might not be set. > When jBPM notifies process A that process B is done, it tries to copy the "out" variable value from process B to process A. If the variable was never set in process B, hence its value is NULL, jBPM throws a RuntimeException because the variable cannot be created in process A with a null value. > The same thing happens if an "in" parameter ("read" access variable) is passed to a subprocess and the variable has not been set. > In either case, an exception should not be thrown, the variable should just not be created on the subprocess for in variables, or copied to the parent process for out variables. -- 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] Resolved: (JBPM-471) createVariableInstance trying to serialize Hibernate objects
