Thow split steps with two identical transition names cause a violation of unique constraint in JBPM4_EXECUTION table.

[JBoss JIRA] Created: (JBPM-2614) TimerSessionBinding does not allow 3rd party TimerSession implementations

TimerSessionBinding does not allow 3rd party TimerSession implementations
-------------------------------------------------------------------------
Key: JBPM-2614
URL: https://jira.jboss.org/jira/browse/JBPM-2614
Project: jBPM
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.x
Reporter: sdfsd sdfsd
We want to use our own scheduler for Timers but even if the infrastracture is in place one can not configure it's own implementation of TimerSession.
The <timer-session/> element allows only target ='ejb' and nothing else will be parsed by the method TimerSessionBinding.parse(). I can't understand why can't I provide my own implementation of TimerSession.
the Solution would be to change add and attribute className to <timer-session/> element and to change the TimerSessionBinding.parse() method like this :
objectDescriptor.setClassName(XmlUtil.attribute(element, "class"));
you can also add a target like 'custom' and only then check the 'class' attribute. Something like this:
public Object parse(Element element, Parse parse, Parser parser) {
ObjectDescriptor objectDescriptor = new ObjectDescriptor();
String target = XmlUtil.attribute(element, "target");
if ((target!=null){
if ("ejb".equalsIgnoreCase(target))) {
objectDescriptor.setClassName("org.jbpm.enterprise.internal.ejb.EnterpriseTimerSession");
}
else if ("custom".equalsIgnoreCase(target))) {
objectDescriptor.setClassName(XmlUtil.attribute(element, "class"));
}
} else {
// wire the JobExecutorTimerSession
objectDescriptor.setClassName(JobExecutorTimerSession.class.getName());
// inject fields
objectDescriptor.addInjection("transaction", new TransactionRefDescriptor());
objectDescriptor.addInjection("jobExecutor", new EnvDescriptor(JobExecutor.class));
objectDescriptor.addInjection("session", new ContextTypeRefDescriptor(Session.class));
}
return objectDescriptor;
}

[JBoss JIRA] Created: (JBPM-2535) Exception during async execution causes multiple instances of the same task being inserted to the database

Exception during async execution causes multiple instances of the same task being inserted to the database
----------------------------------------------------------------------------------------------------------
Key: JBPM-2535
URL: https://jira.jboss.org/jira/browse/JBPM-2535
Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.x
Reporter: Peter Horvath
If a task is reached in an asynchronous execution and notification email sending (or any automated activity)
throws and exception new task instances are inserted to the database on every retry of the asynchronous job.
ExecuteJobCmd creates a JobExceptionHandler to re-try the execution of the job.
Since org.jbpm.jpdl.internal.activity.TaskActivity.execute() method is called on every retry,
and this method creates a new task instance each time it is called, multiple instances of the
same task with the same execution id will be inserted to the database.
All operations that try to query the task by execution will fail due to a NonUniqueResultException.
Example process definition: (note continue="async" attribute on start tag)
<?xml version="1.0" encoding="UTF-8"?>
<process name="task_error" xmlns="http://jbpm.org/4.0/jpdl">
<start name="start1" g="93,78,48,48" continue="async">
<transition name="to Test Task" to="Test Task" g="1,-20"/>
</start>
<end name="end1" g="315,236,48,48"/>
<task name="Test Task" g="178,159,92,52" assignee="johnsmith">
<notification>
<to users="${task.assignee}"/>
<cc addresses="invalid@email@address"/>
<subject>${task.name}</subject>
<text>
<![CDATA[Hi ${task.assignee},

]]>
</text>
</notification>
<transition name="to end1" to="end1" g="-6,-22"/>
</task>
</process>
The notification email will fail (email sender throws an exception) because of the invalid email address (invalid@email@address) that is set in CC tag.
First run fails because of this invalid email address:
SEVERE: exception while executing 'ExecuteActivityMessage[25]'

I believe org.jbpm.jpdl.internal.activity.TaskActivity.execute() method should be modified to try to look up the task instance first and create a new instance only if there is no existing one in the database:
public void execute(ExecutionImpl execution) {
DbSession dbSession = Environment.getFromCurrent(DbSession.class);
TaskImpl task = dbSession.findTaskByExecution(execution);
if(task == null) {
task = (TaskImpl) dbSession.createTask();
task.setTaskDefinition(taskDefinition);
task.setExecution(execution);

[JBoss JIRA] Created: (JBPM-2583) IdentityService createGroup creates duplicate groups
by Robert Moskal (JIRA)
IdentityService createGroup creates duplicate groups
----------------------------------------------------
Key: JBPM-2583
URL: https://jira.jboss.org/jira/browse/JBPM-2583
Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: Runtime Engine
Affects Versions: jBPM 4.1
Environment: JDK 1.6, mysql 5
Reporter: Robert Moskal
Repeatedly calling createGroup with the same group name causes very similar records to be entered into the JBPM_ID_GROUP table. They differ only bythe DBID_ field value. Here is an example of what I found in the database.
17 0 another another (null) (null)
18 0 another another (null) (null)
19 0 another another (null) (null)
20 0 another another (null) (null)
21 0 another another (null) (null)
Retrievals don't result in duplicates, but this seems like it might cause problems.

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

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.
