For folks who think they might need a customized renderer for the
UIData component (perhaps to create some markup other than a table),
the JSF RI comes with some demos -- one demo in particular is a
"Repeater" renderer for UIData that is very easy to subclass and
extend. It has convenient protected methods for things like the
beginning and end of each "row" where you just need to create your own
markup instead of the default.
Download from:
http://java.sun.com/j2ee/javaserverfaces/download.html
and then check out
"samples/components/src/java/components/renderkit/RepeaterRenderer.java"
This is a standard JSF renderer, so it should work on top of MyFaces
as well as the RI.
