I'm pretty sure it's not available right now, but maybe you consider adding such a feature in the future: to execute a partial jsf rerender after a remoting request. It's possible to do right now, but in two HTTP requests (1. remoting, and in the callback execute the jsf rerender).
The use case is quite simple: I have a dynamic form (but dynamic only on the client side, all done with JS), and after filling in the data I want to submit it to the server (using remoting) and rerender a page fragment with the results (using jsf)
I need exactly same functionality with one request/response.
Would be nice if SEAM team pay attention on this.
