Compensation in subprocess failed

Jerome_Dupont · August 31, 2017, 1:29pm

Hi,

I try to reproduce something like here

With the following diagram, the engine throw an error:

Caused by: org.camunda.bpm.engine.ProcessEngineException: ENGINE-09005 Could not parse BPMN process. Errors: 
* cvc-complex-type.2.4.a : Contenu non valide trouvé à partir de l'élément 'bpmn:outgoing'. L'une des valeurs '{"http://www.omg.org/spec/BPMN/20100524/MODEL":eventDefinition, "http://www.omg.org/spec/BPMN/20100524/MODEL":eventDefinitionRef}' est attendue. | simple-compensation.bpmn | line 78 | column 24

at org.camunda.bpm.engine.impl.util.xml.Parse.throwExceptionForErrors(Parse.java:191)

I have to change the XML directly to add compensation start event in subprocess because the modeler don’t authorize me to add one.

Hi @Jerome_Dupont,

according to the BPMN 2.0 standard a sub-process should have only one undefined start event.
The Modeler prevents adding the compensation start event because it can only be used to trigger an event sub-process.

Does this answer your question?

Cheers,
Tassilo

Jerome_Dupont · August 31, 2017, 2:05pm

Yes of course, but the camunda documentation has something like this.

Please take a look at the last diagram here => https://docs.camunda.org/manual/7.4/reference/bpmn20/events/cancel-and-compensation-events/

May be i miss something…

tasso94 · August 31, 2017, 2:12pm

Do you mean this diagram?

This diagram is valid since the compensation start event is located inside of an event sub-process.

Jerome_Dupont · August 31, 2017, 2:16pm

Mine too, no ? But may be i miss something in the doc diagram, because i don’t now how to reproduce the rectangle named “Handle Compensation”. It’s a sub-process ?

Ok, i find how to do it, just add another subprocess and change its type to “event sub-process”. I will try this.

thx

Jerome_Dupont · August 31, 2017, 2:30pm

Ok, i add the event subprocess, but i always have an error. My diagram now is;

The error is:

May be the engine can’t fire both compensation for the book hotel and the subprocess ?

Hi @Jerome_Dupont,

could you please provide a failing test case of your problem?
Please use our test case template.

Cheers,
Tassilo

Jerome_Dupont · September 6, 2017, 3:04pm

I’m not able to reproduce the error with the test case template.

The error is throw by “CompensationEventCoverageHandler” line 38, from the maven dependency:

<dependency>
        <groupId>org.camunda.bpm.extension</groupId>
	<artifactId>camunda-bpm-process-test-coverage</artifactId>
	<version>0.3.0</version>
	<scope>test</scope>
</dependency>

I open an issue on the project => here

Thx

benhoffmann · October 18, 2017, 2:03pm

Hi guys,

I can reproduce the problem with a slightly simpler model. The test fails with the abovementioned NPE, but the model works when I deploy it to a shared Camunda 7.7.0 server.

More details see here in the GitHub issue.

Any ideas about that?

Cheers, Ben
