Chris, I think it has to do with the NavigationPane expecting a
commandNavigationItem only as its direct child. It will blow up if it see
something it does not recognize. With ui:repeat, a ui:repeat "component"
gets built into the tree at build time and its children (the
commandNavigationItems) are read a render time. Since NavigationPane does
not recognize the ui:repeat component, it blows up. With c:foreach, it is
evaluated at during the tree building and only the products of its iteration
(the commandNavigationItems) are built into the tree.
I think I have that right.
Thanks again for helping out and the luck.

Hi Brian,
I'd been able to use ui:repeat in a component without any problems so I'm
not sure what your original problem was related to. However, I'd not been
using the commandNavigationItem either...
Good luck with facelets,
Chris.
