Initial work on the integration allows delegation of the JSF lifecycle to the Spring Web Flow Flow Executor. To allow integration with pages not handled by SWF, only those URLs with no "." after the last "/" are delegated, otherwise JSF handles the request directly. The idea is that this should detect those pages that are "extension mapped". (Clearly a better means of detecting which requests should be handled by Spring Web Flow is needed.)
The booking-faces application has been partially ported and checked in. The flow up to "Book Hotel" is functional; the other pages have not been ported (for instance sf: components currently have interoperability problems due to the use of Dojo and the modification of the form submission URL).
Recent changes for partialSubmit and UIXhtmlComponent state saving improve the functionality of swf-booking-icefaces. A significant area that appears to remain is support for "anonymous" flows. For instance, the login.xhtml page is not registered as a flow, yet redirection to flows/login (and flows/processLogin) is expected to resolve.
