Process instance diagram with REST api

tibere

Hi.

I'm trying to get a diagram instance for a given process, but everytime I'm getting a 404 (for any of my instances id).

Is there something specific that need to be configured when creating the process ? (In the API documentation, it's written that if the user is getting a 404 it is because the process definition does not contain DI information).

Thanks.

Julien

What is the URL you're using? Does the process-definition actually contains graphical information (BPMNDI)?

Hi,

I'm using /service/process-instance/{processInstanceId}/diagram
How can I check that I have graphical information ?
When I'm using the activiti explorer and looking at all my instances, I can see the diagram of each instances. Is that what you mean by BPMNDI ?

Check the XML of your processes. It should contain a section similar to this:

<br><bpmndi:BPMNDiagram><br>&nbsp;&nbsp;&nbsp; <bpmndi:BPMNPlane bpmnElement="Minimal" ><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bpmndi:BPMNShape bpmnElement="_1" ><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <dc:Bounds x="15" y="91" width="48" height="48" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </bpmndi:BPMNShape><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <bpmndi:BPMNShape bpmnElement="_2" ><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <dc:Bounds x="95" y="88" width="83" height="48" /><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </bpmndi:BPMNShape><br>

Also, you can check if "isGraphicalNotationDefined" is true when requesting the process-definition via REST.

Where is defined the "isGraphicalNotationDefined" parameter ?
