ability to create history entry for variables --------------------------------------------- Key: JBPM-2506 URL: https://jira.jboss.org/jira/browse/JBPM-2506 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.0 Reporter: Hauke Rabe ScopeInstanceImpl#createVariableObject has the ability to enable history. But there is only a setVariable method wich disables the history. So, add the history flag to user interfaces. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[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

fix java static factory method use case ---------------------------------------- Key: JBPM-2622 URL: https://jira.jboss.org/jira/browse/JBPM-2622 Project: jBPM Issue Type: Task Security Level: Public (Everyone can see) Reporter: Tom Baeyens Assignee: Tom Baeyens Fix For: jBPM 4.3 this doesn't work as expected. <process name="OrderWithRules"> <start> <transition to="isImportant"> <java var="amount" class="java.lang.Integer" method="parseInt"> <arg><object expr="#{amount}" /></arg> </java> </transition> </start> cause is to be found somewhere in JavaBinding, i think if (XmlUtil.attribute(element, "method", true, parse, null)!=null) { UserCodeReference invocationReference = parser.parseUserCodeReference(element, parse); javaActivity.setInvocationReference(invocationReference); ObjectDescriptor objectDescriptor = (ObjectDescriptor) invocationReference.getDescriptor(); javaActivity.setArgDescriptors(objectDescriptor.getArgDescriptors()); objectDescriptor.setArgDescriptors(null); javaActivity.setMethodName(objectDescriptor.getMethodName()); objectDescriptor.setMethodName(null); } by setting the methodName to null in the object descriptor (objectDescriptor.setMethodName(null)), the object descriptor will not see it as a static factory method, but instead will look for the constructor of the class. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

AssignmentHandler allows assignment of task to non-existing groups ------------------------------------------------------------------ Key: JBPM-2698 URL: https://jira.jboss.org/jira/browse/JBPM-2698 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Environment: Windows Vista, Oracle 11g, jBPM 4.2, Eclipse 3.5 Reporter: Martin Porter Priority: Minor An assignment handler (implementing AssignmentHandler) can invoke assignable.addCandidateGroup(XXX) for groups that do not actually exist in the DB. The group should be validated or else the task will be assigned to a non-existing group and never picked up. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2682) Add problem specific exception sub-classes

by Peter Horvath (JIRA)

Add problem specific exception sub-classes ------------------------------------------ Key: JBPM-2682 URL: https://jira.jboss.org/jira/browse/JBPM-2682 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently error conditions are signaled using a single exception type, JbpmException. Using problem specific exception subclasses would make it possible for the client code to deal with different error conditions differently . Example - current GetOutcomes command implementation: package org.jbpm.pvm.internal.cmd; ... public class GetOutcomes implements Command<Set<String>> { ... public Set<String> execute(Environment environment) { DbSession dbSession = environment.get(DbSession.class); TaskImpl task = dbSession.get(TaskImpl.class, Long.parseLong(taskId)); if (task==null) { throw new JbpmException("task "+taskId+" doesn't exist"); } ... Introducing problem specific exception subclasses would allow client code to handle errors much better; for example if a custom TaskDoesNotExistException (public class TaskDoesNotExistException extends JbpmException) was thrown in GetOutcomes.execute when a task is not found, then the caller code would be able to distinguish this problem from say a transient database connectivity problem. It could display a user friendly error message rather than showing a generic error message etc: public Set<String> execute(Environment environment) { DbSession dbSession = environment.get(DbSession.class); TaskImpl task = dbSession.get(TaskImpl.class, Long.parseLong(taskId)); if (task==null) { throw new TaskDoesNotExistException("task "+taskId+" doesn't exist"); } The same approach for process instances, executions, variables, etc. could be used to allow building robust client code. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2625) Add count() to Queries to support pagination

by Peter Horvath (JIRA)

Add count() to Queries to support pagination -------------------------------------------- Key: JBPM-2625 URL: https://jira.jboss.org/jira/browse/JBPM-2625 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.x Reporter: Peter Horvath Queries provide a powerful interface to access JBPM tasks, jobs, deployments, etc; currently the only way you can get the number of results that match a filter is to load the whole list, and determine its size by calling .size() method - this is extremely inefficient and can even cause OutOfMemoryError (e.g. a HistoryActivityInstanceQuery could return tens of thousands elements) count() could be used with page(int firstResult, int maxResults) method to create a paginated result list where you can display the number of pages -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2648) Candidate-Groups

by Sebastian Castellanos (JIRA)

Candidate-Groups ----------------- Key: JBPM-2648 URL: https://jira.jboss.org/jira/browse/JBPM-2648 Project: jBPM Issue Type: Task Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Reporter: Sebastian Castellanos Hi, I have a problem when seeking tasks using candidate-groups. I created tarea1 which has associated candidate-groups "Group1, Group2, Group3. Then I have a user "sebastian" which is a member of Group 1, Group 2 and Group 3. The problem is that when I run taskService().findGroupTasks("sebastian"); I returned a list of 3 tasks equal, Tarea1, Tarea1, Tarea1. When it should be listed just once the task (Tarea1). I'm not sure if it's a conceptual issue or a bug in the API. I would be grateful for your help. P/d: I'm not using swimlane because I had problems with respect to the Fork / Join. Greetings.
