    Eclipse BPMN 2.0 Plugin

    code_monkey

      Hi,

       

      I've been going through the docs to understand and use jBPM5. On Chapter 9, Eclipse BPMN 2.0 Plugin (http://docs.jboss.org/jbpm/v5.1/userguide/ch09.html), I followed the instructions, but get exceptions in Eclipse when trying to create a model.

       

      I'm using Eclipse 3.7.0 (Indigo). The documentation is out of date. The Graphiti location given doesn't work, but I was able to download the latest version from http://download.eclipse.org/graphiti/updates/0.8.0 . I also installed the BPMN 2.0 editor from codehoop.com (the URL given for it is fine). I start Eclipse according to the jBPM5 installer directions. I can create a new BPMN2 Model, but whenever I try to drag an element onto the canvas I get exceptions. Just trying to create a Start Event gives me an exception (Unhandled event loop exception). I can give further details if requested. Now none of my previous models (created with the older plug-in) will open.

       

      Any idea what's going on? Anything I can try?

          Hi Chris,

           

          Here is a short post about doing just that with the JBoss Dev Studio, which is an older version of eclipse. I hope maybe you just missed something listed here: http://www.schabell.org/2011/03/jboss-developer-studio-40-how-to-add_23.html

           

          Hope it helps, erics

            Thanks, Eric. I looked at your page, but I still have the exceptions when trying to create workflows with the editor. Even a tip on how to remove the editor would be appreciated, since I can't even use the old editor (which worked) now.

              When do you get exceptions? When you execute the process with the engine or during modelling?

               

              I was quite successful with the BPMN 2.0 Plugin. However, I get the same exceptions with it as with the Oryx Web Modeller. After manually moving some tags, the engine starts to understand.

               

              You can deinstall it as follows:

              Above, click already installed (the blue link). Select the plugin.

                Tobias, the Eclipse BPMN2 plugin uses eclipse.bpmn2 just like the web Designer. I will make sure guys working on it can pick up any changes to the eclipse.bpmn2 ecore model that we fix for the designer.

                  This is a biased opinion of course, but I think you should really give the web Designer a try. It has independent release cycles from jBPM and we can turn around fixes fairly quickly and make sure you get them in a release much faster.

                    I am also much happier with the web designer. It is a bit more intuitive and there is more manual work involved with the eclipse plugin. However, sometimes I use the bpmn2 eclipse plugin to enrich things.

                      Hi Tihomir!

                       

                      When I get loose from my day job again (bit flooded since returning from vacation) I will try to feed you some input on the turnaround when using that designer together with the embedded old Drools designer in Eclipse.

                       

                      I am working on the jBPM Migration project and it is really a pain to even try to adhere to the thre (3) different designers when migrating a jPDL design to  BPMN2. So far I have been hampered to using only the Drools designer as my basic target display. This means I have been creating 'domain specific' nodes when wanting to try and display a non-exitant Gateway for example (there are only 2 avail).

                       

                      Anyway, nice to meet you, hope to provide input sometime in the near future, maybe use your designer as my target! ;-)

                       

                      PS. I have not looked, but does that designer have an XML view?

                        From what I experienced, you can view the source in a popup window to preview the xml, however it is not an xml editor.

                          Yes, currently standard Guvnor asset source view popup window. We will keep improving this over time, for example short-term https://issues.jboss.org/browse/JBPM-3322. And we will keep adding new features to the toolbar when Designer editor is used.

                           

                          Hope this helps.

                            I get the exceptions during modelling, when I try to add a node or event. It just reports the exception and doesn't place the node. I get different exceptions when I try to open old previous models (.bpmn files). It doesn't successfully open them.

                             

                            Here's the first few lines of the exception I get:

                            I DO have graphiti installed, though it's a newer version than the one mentioned in the docs. The old one isn't available anymore, from what I can tell. Even so, the newer version should be backwards compatible with the old version, no?

                             

                            Thanks for any pointers!

                                Sounds very similar as reported bug https://github.com/imeikas/BPMN2-Editor-for-Eclipse/issues/3, even tho I cannot find a JBPM Jira for it like indicated would be done in the comment.

                                  I got the same problem. I tried to search other resources without success. I see that the bug is not assigned to anyone.

                                  So the only solution for the moment seems to be downgrading to the previous version. I uninstalled the plugins, then I restarted from version 0.7.2 of Graphiti.
