I tend to flip flop between the two, primarily because a bug somewhere else in my code is causing the ui:repeat to not work or vice versa. I'll start using ui:repeat instead. Any pointers to required reading that will help me understand when I can use the parameters and when they won't be able to be resolved? Seam + facelets +ajax4jsf is really nice, I really started to see the power last night when I was working with tables within tables and optionally rendered drop downs etc. These function parameters really helped simplify the tables within tables scenario versus using @DataModelSelection .
