JSF 2.0-2.3 Progress of Iterable/Map support in UIData/UIRepeat (OmniFaces support via utility functions)

Support for the Map interface in UIData and UIRepeat, by Arjan Tijms

Convert a Iterable<E> to a List<E>

Convert a Map<K, V> to a List<Map.Entry<K, V>>

Convert a Set<E> to a List<E>

Iterating in UIData (e.g. <h:dataTable>)

JSF 2.0/2.1

- supports the List, native array and JSF specific DataModel as input for its value binding

- for Iterable (e.g. Queue, Set) you can use the OmniFaces function, of:iterableToList().

- for Set only (especially useful to Hibernate/JPA users, who are usually using the Set collections for entity relationships)
  you can use the OmniFaces function, of:setToList().

- if EL 2.2 is available, for Iterable, you can use toArray() (e.g. #{fooBean.fooIterable.toArray()}).

- for Map you can use the OmniFaces function, of:mapToList().

- if EL 2.2 is available, for Map, you can use toArray() (e.g. #{fooBean.fooMap.entrySet().toArray()} or #{fooBean.fooMap.keySet().toArray()}
  or #{fooBean.fooMap.values().toArray()}).

JSF 2.2                                                                                          

- supports the List, native array and JSF specific DataModel as input for its value binding

- you can use directly the Iterable (e.g. Set, Queue)

- for Map you can use the OmniFaces function, of:mapToList().

- since Iterable is directly supported, you can use  it as #{fooBean.fooMap.entrySet()} or #{fooBean.fooMap.keySet()}or #{fooBean.fooMap.values()}

JSF 2.3                                                                                          

- supports the List, native array and JSF specific DataModel as input for its value binding

- you can use directly the Iterable (e.g. Set, Queue)

- you can use Map directly

<h:dataTable value="#{fooBean.fooMap}" var="t">

 #{t.key} #{t.value}

</h:dataTable>
