Error uploading a jpdl file with a wrong version format (aka: 1.0.0) which leaves the database inconsistent (bad formatted jpdl file) and does not let upload a new process definition with the same Name, because the service attempts to retrieve the previous version and throws an exception when parse the file. (NOTE: I am uploading a BAR file and the jpdl file is inside the bar)
In the RepositorySessionImpl you are doing the following steps:
session.save(deploymentImpl); // will also save the attached resources
deployerManager.deploy(deploymentImpl);
That saves the Deployment data before checking the consistency of the jpdl file.

[JBoss JIRA] Created: (JBPM-2807) A task is put in an unusable state if the execution it belongs to is signalled

A task is put in an unusable state if the execution it belongs to is signalled
-------------------------------------------------------------------------------
Key: JBPM-2807
URL: https://jira.jboss.org/jira/browse/JBPM-2807
Project: jBPM
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: jBPM 4.0, jBPM 4.1, jBPM 4.2, jBPM 4.3, jBPM 4.x
Reporter: Ronald van Kuijk
Priority: Minor
Fix For: jBPM 4.x
When an execution is signalled, the task belonging to that execution becomes unusable. It is made 'not-signalling', has no exection (thus cannot be ended, which you would not want to) but it keeps showing up in the tasklist....
Proposed solution is to have an additional task state (like the 'timeout' that is introduced). If an execution is signalled, the task is 'cancelled' this is something completely different then it being completed or any other state....
The behaviour of which transition will be taken will not be different from what it is now.... A warning will be logged that a execution is signalled and it would be better to act on the task itself...
Subtasks will/should be treated the same.

nested Forks

Hi,
I have a situation where you have two nested fork, at the first fork left a task unfinished and launched the second fork with two more tasks, but when it launches the second fork, I repeat one of the tasks of the second Fork.
it means if the second Fork is associated with(Task 1, Task 2), when executed, throws (Task 1, Task 2, Task 1).
The second fork should not only launch their two tasks?, By repeating one of them?. this is normal operation with two nested Fork?.

[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 ${task.assignee},
Task "${task.name}" has been assigned to you.

]]>
</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:

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

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.

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 doesn't work as expected.

<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.
