> 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.
