I'm using latest Eclipse Juno and JSF 2.2.m05. There are several new tags in JSF 2.2, like the new Flow feature. My problem is that Eclipse won't read the taglibs descriptors from the latest JSF 2.2 libraries.
In Project Facets -> Java Server Faces -> User Library, I have set up a library that points to the jsf-api and jsf-impl for JSF 2.2.m05
Still Eclipse code completion won't respect new tags.
