Don't know if this has been discussed here before... I am getting warnings that the 'forceId' attribute is not on various types, e.g., org.apache.myfaces.component.html.ext.HtmlInputText. I recently ported to facelets and I don't remember seeing this warning when I was just using myfaces alone.
I saw a work-around, but I am wondering whether I have to do some additional configuration.
