[jboss-jira] [JBoss JIRA] Updated: (JBRULES-2519) Support integration with external editor for BPMN 2.0 edition

Support integration with external editor for BPMN 2.0 edition ------------------------------------------------------------- Key: JBRULES-2519 URL: https://jira.jboss.org/browse/JBRULES-2519 Project: Drools Issue Type: Feature Request Security Level: Public(Everyone can see) Components: drools-guvnor Affects Versions: 5.1.0.M1 Reporter: Antoine Toulme Assignee: Mark Proctor Attachments: diff_resources.txt, JBRULES-2519.txt And before you ask, the editor is Oryx. So here is how it goes. We use a GWT object to create an editor. The editor loads Oryx as an iframe, taking control over it by making sure domains match. When we click on Save, the GWT object talks with the editor to get the current model (in JSON). It saves the JSON. Load is a bit trickier. We load the model from the repository, (note that since Oryx use JSON to load its internal model, I am being very forgiving of what is being loaded, which is bad). I used a separate servlet for this as I didn't know Seam well. When loading the iframe, I add a parameter to the URL of the iframe, "uuid". The parameter is used to call the servlet, which returns the model as JSON. It works like a charm on Safari but needs to be QA'ed on different browsers. Of course, hacking Guvnor is only half the battle. Most of the changes went to Oryx. We maintain a branch of Oryx with those changes here: http://github.com/intalio/process-designer/ I will also open bugs for those changes to be brought back to the stock Oryx repo.
