Hmmm. This is very weird. I had a look at the Mojarra sources. It looks like the ViewHandler returns null or an empty string in your case. My first guess is that it’s not the PrettyViewHandler that is causing this. Are you using any other JSF libraries? Or are using some own custom ViewHandler?

I think some debugging would be helpful? Any chance that you can debug a bit and check why FormRenderer in line 166 gets an empty URL from the ViewHandler?

Or could you create a minimal sample app that reproduces this. In this case I could help with the debugging.

Thanks
