piranha: AJAX functionality not working

I have been playing around with MyFaces and Mojarra in conjunction with Piranha Micro (and embedded). Most JSF functionality seems to work using the provided artifacts - with the exception of AJAX calls. I have tried vanilla <f:ajax> and PrimeFaces update attributes with no success. The result is the same with both MyFaces and Mojarra.

I’ve kept it simple and I’m using the DefaultHttpServer implementation.

Am I I missing something ? Is it supposed to work ? If so - tips are appreciated. As it is, I can see the request is actually sent - but beyond that it doesn’t seem to be able to associate or get any response back.
