Question

JSF -- <ui:repeat /> over a java.util.Set?

Answer 1

+2 A:

Consider using c:forEach instead. It appears that ui:repeat does not support sets (i.e. requires some sort of ordering property).

Otherwise you can create your own tag as described in: http://techblog.bozho.net/?p=28

Do **NOT** consider using `c:forEach`: http://www.ilikespam.com/blog/c:foreach-vs-ui:repeat-in-facelets

It completely depends on what the set is that you are iterating over and if it compile time or not. So if that is the case then you CAN use `c:forEach`.

Yes if you know what you are doing, then you can use `c:forEach`, but I read your post as that `you should consider using c:forEach`, and this is not the case. Better using `ui:repeat` to avoid problems

Answer 2

+5 A:

No the ui:repeat does not support Set. Nor does h:dataTable.

You should return a List from the Set, and use that instead.

public List<T> getListAsSet(Set<T> set) {
  return new ArrayList<T>(set);
}

You should avoid using c:forEach. Why can be read here
