Important information for update to `1.1.23` Layout can be broken

[paule96]

Before version 1.1.23 a diagram area in the xml like this was allowed:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<bpmn2:definitions xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:hmp="hmp" xmlns:dc="http://www.omg.org/spec/DD/20100524/DC" xmlns:di="http://www.omg.org/spec/DD/20100524/DI" xmlns:open-bpmn="http://open-bpmn.org/XMLSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" exporter="org.openbpmn" exporterVersion="1.0.0" targetNamespace="http://open-bpmn.org" xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL">
  <bpmn2:process id="process_1" name="Default Process" processType="Public">
      ...
  </bpmn2:process>
  <bpmndi:BPMNDiagram id="BPMNDiagram_1" name="OpenBPMN Diagram">
    <bpmndi:BPMNPlane id="BPMNPlane_1">
       ...
    </bpmndi:BPMNPlane>
  </bpmndi:BPMNDiagram>
</bpmn2:definitions>

But now you need to specify on the element BPMNPlane also an BpmnElement, like that:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<bpmn2:definitions xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:hmp="hmp" xmlns:dc="http://www.omg.org/spec/DD/20100524/DC" xmlns:di="http://www.omg.org/spec/DD/20100524/DI" xmlns:open-bpmn="http://open-bpmn.org/XMLSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" exporter="org.openbpmn" exporterVersion="1.0.0" targetNamespace="http://open-bpmn.org" xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL">
  <bpmn2:process id="process_1" name="Default Process" processType="Public">
      ...
  </bpmn2:process>
  <bpmndi:BPMNDiagram id="BPMNDiagram_1" name="OpenBPMN Diagram">
    <bpmndi:BPMNPlane id="BPMNPlane_1" bpmnElement="process_1">
       ...
    </bpmndi:BPMNPlane>
  </bpmndi:BPMNDiagram>
</bpmn2:definitions>

If you don't do it your diagram will look like that:

Their is no need to fix it, but it would be nice to have it has a release note about that behavior change.

Thanks for your feedback. This is an interesting cased and of course this should not happen. Can you provide an example diagram that caused the problem? Than I will investigate into this issue.

Just create any diagram with more then one element, go into the xml view and delete the BPMNElement attribute on the bpmnplane and reopen the diagram in the visual editor.

Note really reopen the visual editor. If the editor is running while changing the xml, it seems for me to not update

I have created a separate bug report: imixs/open-bpmn#427
