Does not throw any errors.ProcessEngine processEngine = ProcessEngines.getProcessEngine(dbname);RepositoryService repositoryService = processEngine.getRepositoryService();BpmnModel pm = repositoryService.getBpmnModel(process

If it's not returning an error what's the issue? Is it returning a null value?

Best regards,

Sorry, should have been more clear. It is not returning the diagram. Returns null.

Can you post the process xml which fails? That would help us tremendously.

This XML works fine for me. But you are using the ProcessDiagramGenerator in a static way, that's not correct. I used the following line:

InputStream imageStream = new DefaultProcessDiagramGenerator().
generateDiagram(pm, "png", runtimeService.getActiveActivityIds(pi.getId()));

Also are you sure the process instance is running?

Best regards,

It works now changing code to use the new DefaultProcessDiagramGenerator(). Everything worked fine up to 5.15.1. I have been using this same code for awhile now. This is used in an embedded app with our own front end GUI.

Thanks for the help
