This REST endpoint should already provide that:

GET runtime/process-instances/{processInstanceId}/diagram

Best regards,

The REST endpoint (5.18)
GET runtime/process-instances/{processInstanceId}/diagram

only seems to highlight the current pending execution step (waiting). It doesn't seem to draw RED lines for the flow transition (lines) between the steps that have been completed. However, in Activiti Explorer (5.18) the diagram for a process instance does show the flow transitions in RED. I am not sure if it is just coloring any transition to the pending execution step, or if it is looking at the History to identify them. Anyone know how these two (REST endpoint for diagram highlight and Activiti Explorer process instance diagram) handle making these flow transition lines RED?

I was thinking we could just get a distinct list of the Ids for these from ACT_HI_DETAIL (or related History REST endpoint) for the process instance Id and color them RED if they are returned in the response recordset. Does this sound right? Any pointers?

You may get the completed activities from history service and highlight them with a different colour, just like the active task is coloured in red by current picture generator. I have done a crude highlighter of completed tasks. It will be very appreciated if this feature is part of core functionality. Couldn't attach the image because of forum policy.

Hi, Mr_Mister
Did you find the way of highlighting? Could you suggest it if you did it…
Thank you.

Hi,


  public InputStream generateDiagram(BpmnModel bpmnModel, String imageType, List<String> highLightedActivities, List<String> highLightedFlows,
      String activityFontName, String labelFontName, ClassLoader customClassLoader, double scaleFactor) {
    
    return generateProcessDiagram(bpmnModel, imageType, highLightedActivities, highLightedFlows, 
        activityFontName, labelFontName, customClassLoader, scaleFactor).generateImage(imageType);
  }
