Problem beim Deployment

[Felix Claus]

Hi.

wir nutzen Camunda in der Hochschule. Nur leider habe ich folgenden
Fehler wenn ich mein BPMN Modell deployen möchte:
"org.camunda.bpm.engine.ProcessEngineException: Cannot find validator
implementation for name 'null'. | modell.bpmn | line 52 | column 36"

Ich habe das BPMN Modell auch schon komplett geleert oder auch nur ein
simples Start - Task - Ende Konstrukt ausprobiert. Es kommt immer der
selbe Fehler.

Können Sie mir da evtl. weiterhelfen?

Vielen Dank bereits im Voraus.

Mit freundlichen Grüßen
Felix Claus

P.S.
Hier mal die komplette Meldung:

Hi Felix,

Please provide your model (you can use http://camunda.org/share for convience), we need to know what at line 52 is.

Cheers

Hi Christian,

the uploader always tells me that the xml document is no BPMN 2.0 XML document.
So i pick out the part where the problems appear (Line 52 is <camunda:constraint/>)

<userTask id="UserTask_2" camunda:candidateGroups="Entscheider" name="Hard- und Softwareauswahl">
<extensionElements>
<camunda:formData>
<camunda:formField id="tablet" label="Tablet" type="boolean">
<camunda:validation>
<camunda:constraint/>
</camunda:validation>
</camunda:formField>
<camunda:formField id="mindmanager" label="Mindmanager" type="boolean"/>
<camunda:formField id="visio" label="Visio" type="boolean"/>
<camunda:formField id="pms" label="Projektmanamgent-Software" type="boolean"/>
</camunda:formData>
</extensionElements>
<incoming>SequenceFlow_2</incoming>
<outgoing>SequenceFlow_3</outgoing>
</userTask>

Kind regards,
Felix

Hi again,

i tried it with a complete new BPMN File.
But he still tells me the same Error with the same file. But the file did not exist anymore ...

[fe...@claus.de]

Hi,
I have solved the problem.
I made a new BPMN file and reloaded the Camunda JBoss.
Now everything works.
Thank you for you support!

[Christian Lipphardt]

Hi Felix,

Your Problem was you did not include a "name" attribute for the camunda:constraint.

See http://docs.camunda.org/latest/guides/user-guide/#tasklist-task-forms-generated-task-forms for an example.

Cheers

Christian
