Plugin displays blank window when opening *.bpmn20.xml #243

Closed joemcerlane closed 3 years ago

joemcerlane commented 3 years ago

Describe the bug Click on any of the .bpmn20.xml files and view BPMN diagram opens a blank window

In this instance I am using a simple test file:

<?xml version="1.0" encoding="UTF-8"?>

<definitions xmlns="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:activiti="http://activiti.org/bpmn" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:omgdc="http://www.omg.org/spec/DD/20100524/DC" xmlns:omgdi="http://www.omg.org/spec/DD/20100524/DI" typeLanguage="http://www.w3.org/2001/XMLSchema" expressionLanguage="http://www.w3.org/1999/XPath" targetNamespace="http://www.activiti.org/test">

<process id="my-process">

    <startEvent id="start" />
    <sequenceFlow id="flow1" sourceRef="start" targetRef="someTask" />

    <userTask id="someTask" name="Activiti is awesome!" />
    <sequenceFlow id="flow2" sourceRef="someTask" targetRef="end" />

    <endEvent id="end" />

</process>

Expected behavior I'd like to view a diagram, I've attached a screenshot to show the behaviour when view opened via "diagrams"->"Show BPMN Designer 2.0..." in which you can see the diagram displayed.

@joemcerlane Thanks for the feedback, but please provide the entire BPMN file, it is impossible to debug issues without it. Also, this plugin requires DI (Diagram Tags) to display diagrams (this is the way Flowable and Activit 6.x modelers work), so maybe your XML is missing DI section

Thanks for the swift response, that is the full content of the BPMN file I took from here: https://github.com/Activiti/activiti-unit-test-template/blob/master/src/test/resources/org/activiti/test/my-process.bpmn20.xml Not sure what DI (Diagram Tags) if this https://www.jetbrains.com/help/idea/diagrams.html then I'm good as that is how I was able to display the diagram in the screenshot, however flowable/activiti plugin don't wish to play ball Any verification steps you would recommend on my end?

valb3r commented 3 years ago

The DI (Diagram Tags) is a bpmndi:BPMNDiagram XML tag and its children. For example: https://github.com/valb3r/flowable-bpmn-intellij-plugin/blob/master/activiti-xml-parser/src/test/resources/duplicates.bpmn20.xml#L17

The example you have provided lacks these, as Activiti BPMN engine does not need bpmndi:BPMNDiagram, it only needs process definition. bpmndi:BPMNDiagram tag defines human-friendly element layout that is shown to the user. This plugin requires them and they are created when you are using Activiti-modeler as well

No diagram rendering might be done within https://github.com/valb3r/flowable-bpmn-intellij-plugin/issues/203

Gotcha @valb3r thanks for clearing up the confusion 👍
