Poll with ajax in ManagedBean of @ApplicationScope


Poll with ajax in ManagedBean of @ApplicationScope

seems to work fine The submits/processes by default the entire form as in . Including the current slider value. You should have noticed it by an unnecessary set method call. Every open view submits its own current slider value during the poll. That's why every open view only gets to see its own slider value (leaving race conditions outside consideration when there are "many" open views).
Tell to only process itself, not the entire form.
code :
<p:poll process="@this" ... />

AJAX Polling Frequency - To long poll or not to long poll?

AJAX Polling Frequency - To long poll or not to long poll?

around this issue Long polling will scale better (i.e. less server load) than polling, while giving much better response times.
If your recipient polls, the average journey time of a message will be half your poll interval.

help you fix your problem You're apparently trying to access it in the constructor of the parent bean. This is indeed not possible. The managed properties are injected after construction.
code :
ParentBean parentBean = new ParentBean(); // Constructor invoked.
parentBean.setChildBean(new ChildBean()); // Managed property set.
@ManagedProperty("#{childBean}")
private ChildBean childBean;

@PostConstruct
public void init() {
    System.out.println(childBean); // Not null.
}

hop of those help? It seems that you've managed to get your setTimeout delay argument written in the wrong place.
code :
$(document).ready(function() {
  (function poll() {
    setTimeout(function() {
        $.ajax({
            url: "/project1/api/getAllUsers",
            type: "GET",
            success: function(data) {
                console.log("polling");
            },
            dataType: "json",
            complete: poll,
            timeout: 5000
        }) //, 5000  <-- oops.
    }, 5000); // <-- should be here instead
  })();
});​
setTimeout(function () {
    $.ajax(), 5000
})
setTimeout(function () {
    $.ajax();
}, 5000)

I hope this helps you . why i see this error message "( ! ) Notice: Undefined index: poll in D:\wamp\www\poll\poll.php on line 6" in the ajax when i try to poll .. i have two files , Change line 6 of poll.php from:
code :
if(!$_POST['poll'] || !$_POST['pollid']){
if(!isset($_POST['poll']) || !isset($_POST['pollid'])){
if($_GET["result"]==1 || $_COOKIE["voted".$poll_id]=='yes'){
if((isset($_GET["result"]) && $_GET["result"] == 1) || (isset($_COOKIE["voted"  .$poll_id]) && $_COOKIE["voted" . $poll_id] == 'yes')){
Ajax voting poll works directly, but not through a second ajax call

around this issue I guess the problem is the $(function() {...}); call, which is essentially a shortcut for $(document).ready(function() {...});. When you change the DOM using your Ajax call, the document ready event not fired, so your event handlers won't bind.
Using Event Delegation, you could try $('body').on('submit', '#votePoll', function() {...}); in your index.php instead of your event handler in poll.php. This should bind your event handler to all current and future #votePoll elements inside the body.
