I am not using a lot of the advanced facelets features, but I've found some of the basic features to be quite helpful.
* Building composite components is trivial (although t:aliasBean can also do this) * The error reporting from facelets quickly and accurately shows me what's wrong. It can take me hours to figure out why a jsp error is occurring. * Facelets supports both JSF 1.1 and JSF 1.2, so some JSF 1.2 features are already available to fix problems with JSF 1.1 issues (like converters and validators being recreated each request). * Facelets supports JSF EL functions, which is currently not possible with MyFaces alone. * You can design components without writing JSP Tag handlers. There are some downsides, though. * You have to create a facelet tag configuration file if the components you want to use don't come with them. Most of the time this is pretty (identify the namespace, the component tag, the component type, and the component renderer type), but components that do complex things in the JSP Tag or support unusual method binding signatures can require work to get working again. t:updateActionListener, sandbox:graphicImageDynamic, and jenia4faces:popupFrame (and probably Tree2 and JsCookMenu) are examples of these. However, it's pretty easy to write facelet tag handlers (easier than the original Tag class in most cases). We're starting a collection of these at http://cvs.sourceforge.net/viewcvs.py/jsf-comp/facelets/tagHandlers. But if no one else has needed the component yet, you'll have to write the first draft of the tag handler. * Facelets exposes bugs in the JSF implementation. Sometimes the JSF implementation only works for the JSP ViewHandler. Facelet use tends to expose bugs that you won't see when you're using JSP, and it can sometimes take a while before the facelets team and JSF teams get them worked out.
