Missing activiti:formKey in StartEvent cause userTask to skip?

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

if I don't use activiti:formKey="wf:submitAdhocTask" inside startEvent, then the workflow skip addUpdateTask and go straight to ReviewTask. Do anyone know why this happens?  I am new to alfresco
Thanks,

Hi,

The "activiti:formKey" does not affect the workflow order. The "sequenceFlow" affects the order, and in you workflow, this is correct:

<sequenceFlow id="flow1" sourceRef="alfrescoStartevent1" targetRef="addUpdateTask"></sequenceFlow>
<sequenceFlow id="flow2" sourceRef="addUpdateTask" targetRef="ReviewTask"></sequenceFlow>
<sequenceFlow id="flow3" sourceRef="ReviewTask" targetRef="endevent1"></sequenceFlow>

Maybe you have a confusion, why the "formKey" and "candidateGroup" of the "addUpdateTask" and the "ReviewTask" is the same.

If the problem persist, Can you send more information (i.e.: screenshot)?

Greetings,
Arak.
