[JBoss JIRA] Created: (JBPM-2951) TaskService.completeTask fails when called with variables but no outcome

by Jon Kranes (JIRA)

TaskService.completeTask fails when called with variables but no outcome ------------------------------------------------------------------------ Key: JBPM-2951 URL: https://jira.jboss.org/browse/JBPM-2951 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Reporter: Jon Kranes Given a task 'task1' with a single named transition, if I call the variant of completeTask that takes the taskID and a Map of variables, the result is an error: "No unnamed transitions were found for the task 'task1' According to the user guide (Section 5.7), if a task has one outgoing transition with a name, then calling compeleteTask(id, null) is expected to result in an error. It appears that calling completeTask(id, variables) is being treated as equivalent to calling completeTask(id, null, variables) and thus causing an error. This behavior seems incorrect -- completeTask(id, variables) should, aside from setting variables, follow the behavior of completeTask(id), which according to the user guide will complete the task and take the single outgoing transition regardless of whether it is named or not. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2962) Retrieving variable with null value failed in scripts

[JBoss JIRA] Created: (JBPM-2966) cancel and error end activity throws exception in subprocess

by Philipp Ossler (JIRA)

cancel and error end activity throws exception in subprocess ------------------------------------------------------------ Key: JBPM-2966 URL: https://jira.jboss.org/browse/JBPM-2966 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Environment: jBPM 4.4 Reporter: Philipp Ossler I created a simple process which includes a state and a subprocess with different end activities The subprocess is similar to the example in user guide > http://docs.jboss.com/jbpm/v4/userguide/html_single/#endstate. When I send the signal "end" to the state in the subprocess, the process wait in state "end state". That's correct! But if I send the signal "cancel" or "end", a JbpmException "execution[...] has running subprocess: execution[...] in state cancel/error" throws. This exception throws in method checkActive() of the class ExecutionImpl. {code:java} if (!isActive()) protected void checkActive() { if (!isActive()) { throw new JbpmException(toString() + " is not active: " + state); } else if (this.subProcessInstance != null && !Execution.STATE_ENDED.equals(this.subProcessInstance.getState())) { throw new JbpmException(toString() + " has running subprocess: " + this.subProcessInstance.toString() + " in state " + this.subProcessInstance.getState()); } } {code} The problem is that the methode only check if the subprocess has the state "end". I think the method have to check if the subprocess state is one of {end, cancel, error}.

[JBoss JIRA] Created: (JBPM-2969) DST switching not considered for in BusinessCalendarImpl

[JBoss JIRA] Created: (JBPM-2970) DbSessionImpl.deleteProcessDefinitionHistory causes foreign key constrain violation for FK_HACTI_HPROCI

by Michael Wohlfart (JIRA)

DbSessionImpl.deleteProcessDefinitionHistory causes foreign key constrain violation for FK_HACTI_HPROCI ------------------------------------------------------------------------------------------------------- Key: JBPM-2970 URL: https://jira.jboss.org/browse/JBPM-2970 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4 Environment: ubuntu 10.10, OpenJDK1.6 Reporter: Michael Wohlfart Priority: Minor DbSessionImpl.deleteProcessDefinitionHistory(String processDefinitionId) needs to remove HistoryActivityInstanceImpl when deleting HistoryProcessInstanceImpl since there is a foreign key constrain FK_HACTI_HPROCI in the hibernate mapping, the following implementation should do the trick: public void deleteProcessDefinitionHistory(String processDefinitionId) { List<HistoryProcessInstanceImpl> historyProcessInstances = session .createCriteria(HistoryProcessInstanceImpl.class) .add(Restrictions.eq("processDefinitionId", processDefinitionId)) .list(); for (HistoryProcessInstanceImpl hpi : historyProcessInstances) { List<HistoryActivityInstanceImpl> historyActivityInstances = session .createCriteria(HistoryActivityInstanceImpl.class) .add(Restrictions.eq("historyProcessInstance", hpi)) .list(); for (HistoryActivityInstanceImpl hai : historyActivityInstances) { session.delete(hai); } session.delete(hpi); } } -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2973) Database constraint violation occurs after fork / join when one branch is a subprocess

by Jon Kranes (JIRA)

Database constraint violation occurs after fork / join when one branch is a subprocess -------------------------------------------------------------------------------------- Key: JBPM-2973 URL: https://jira.jboss.org/browse/JBPM-2973 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.4 Environment: Windows XP, JDK 1.6, PostgreSQL Reporter: Jon Kranes Given a process and subprocess with the following characteristics: * A fork node that splits execution into two parallel paths * A corresponding join node with multiplicity=1, indicating that execution should continue when the node is reached from either of the parallel branches * At least one of the branches invokes a sub-process The expected behavior is that if either branch completes, execution should continue from the join node and all pending activities on the other branch should be deleted. However, in the case where the sub-process branch is waiting for task completion, and the task on the other branch is completed, the task completion call fails with a database constraint violation: ERROR: update or delete on table "jbpm4_execution" violates foreign key constraint "fk_exec_superexec" on table "jbpm4_execution" This works as expected when no sub-processes are involved, i.e. if both branches are just composed of tasks in the main process. It also works as expected if the sub-process branch is the one that completes first. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2972) Update jpdl XSD with fork transition conditions

by Mike M (JIRA)

Update jpdl XSD with fork transition conditions ----------------------------------------------- Key: JBPM-2972 URL: https://jira.jboss.org/browse/JBPM-2972 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.4, jBPM 4.3 Reporter: Mike M The jpdl xsd needs to be updated to reflect the fact that transitions in fork activities can have nested condition elements. Looking at the code for ForkActivity, it's apparently that <fork> activities do evaluate conditions for outgoing transitions. Example: <fork name="fork1"> <transition to="always_do_this"/> <transition to="sometimes_do_this" > <condition expr="#{my_boolean_expression}"/> </transition> </fork> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
