Description of problem: Problem with creation of process diagram for jBPM console. I think that current implementation is not user friendly. Diagram is not created in assets without clicking on icon "View in PNG". This process should be automatic. The icon should be used to download current diagram. It should not be used to generate diagram for jBPM console. Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Create a new process in Knowledge Base 2. Add and set some elements(tasks, start,terminate etc.) 3. Save the process 4. Open assets Actual results: You do not find {processID}-image.png in assets. Expected results: Designer should generate {processID}-image.png automatically during saving the process because this file is required for viewing the state of instance in jBPM console. Additional info: Actual icon "View in PNG" generates {processID}-image.png in assets only if a process is saved.
Clicking "View PNG" also results in an error in the server log, though the picture is generated just fine (it seems) and is downloaded and viewable. 15:10:44,857 ERROR [STDERR] org.w3c.dom.DOMException: <unknown>: The attribute "stroke-dasharray" represents an invalid CSS value ("").
