Chris, Yes, I am aware that I can call Java methods from the flow. The result however is a bigger spagetti than if I only used Java.
If someone can produce a version of the XMLForm demo wizard which uses the flow and produces the same result with significantly less code and better readability, I would consider that a serious step ahead.

Rhino provides bidirectional interoperability with Java: you can create java objects and call their methods from JavaScript, and you can extend Java classes and implement Java interfaces in JavaScript.

The discussion how to combine the two has been going on forever, but we have not come to an agreement. I would gladly offer my tactical guidance for your effort. The biggest issue that I had so far with the flow is how to implement in an elegant way, navigation logic which depends on domain knowledge. For example how to do a wizard where the next page (Car Models) depends on a selection on the previous (Brand Name) as well as a lookup to an external resource (BMW's Web Service providing a list of current car models or a db query). If I was to do this with Actions, I could use well known and standardized Java APIs - JWSP or JDBC. Maybe my issue is that I used the Struts model for too long and I can't get out of the box.
