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

The easiest way to finish the deal at page without modifying the class is converting the set to an array like this.

<ui:repeat value="#{myBean.mySet.toArray()}" var="_myvar">

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> getListFromSet(Set<T> set) {
  return new ArrayList<T>(set);
}

You should avoid using c:forEach; here is an article on why.
