Q: migrating to Facelets

[Yee CN]

Hi,   I am thinking of migrating to Facelets and I need to gauge the efforts required. Assuming that my jsf pages are relatively pure (i.e. no jstl etc), would my pages compile and run as it is without modifications? I got the impression that this is so – can someone please confirm?   Is there any gotcha to watch out for?   Many thanks.   Best regards, Yee
