Java autocomplete' s not working after create row on primefaces

In my application i added java autocomplete to searchitem.
This item is working good. But it s not working after create row.
i recorded video to youtube.
https://www.youtube.com/watch?v=0FM52YNsDZY
page :
<p:autoComplete id="autocomplete" dropdown="true" value="#{126Controller.tesisAuto}" var="auto"
completeMethod="#{211Controller.complete}" forceSelection="true"
itemLabel="#{auto.tesisAdi}" itemValue="#{auto}">
<f:facet name="itemtip">
<h:panelGrid columns="2" cellpadding="5">
<h:outputText value="Tesis Adı: "/>
<h:outputText value="#{auto.tesisAdi}"/>
<h:outputText value="Şeflik Adı: "/>
<h:outputText value="#{211Controller.getSeflik(auto.seflikKodu)}"/>
<h:outputText value="Adres: "/>
<h:outputText value="#{auto.adres}"/>
</h:panelGrid>
</f:facet>
<p:ajax event="itemSelect" listener="#{126Controller.itemByTesisAuto()}" update=":126ListForm:display"/>
</p:autoComplete>
Complete method:
public List<211> complete(String query) {
return autoComplete(query);
}
public List<211> autoComplete(String auto){
List<211> completed = new ArrayList<211>();
for (211 m211: this.getFacade().getTesisByYetkiIsyeriKodu(yetkiSeflik)){
if(m211.getTesisAdi().startsWith(auto.toUpperCase())){
completed.add(m211);
}
}
return completed;
}
Create method:
public void create() {
persist(PersistAction.CREATE, "Oluşturma");
if (!JsfUtil.isValidationFailed()) {
items = null; // Invalidate list of items to trigger re-query.
}
}

Primefaces ajax not working update on field datatable

I have problem with "" component in my application. I have a datatable with 2 fields editable first is an inputtext and second field is a dateInput.
Inside fields I put to update value in list but when submit it to bean not updated the values.
Below is my page.xhtml and bean.
<p:dialog id="modalNovosParametrosRecesso" header="Salvar Novos Parâmetros de Estagiário"

My Bean:
public void salvarRecessoPrimeiraParametrizacao(){
int count = 0;
final DataTable dataTable = (DataTable) FacesContext.getCurrentInstance().getViewRoot()
.findComponent(":frmFiltro:tableRegRecessoAuto");
List<OcorrenciaPonto> teste = new ArrayList<OcorrenciaPonto>();
for(OcorrenciaPonto c : (List<OcorrenciaPonto>) dataTable.getValue()){
teste.add(c);
count+=1;
}}
datatable.getValues() not get new values and yes old values that displayed in screen.

Are you using getters and setters correctly?
Have you tried to use immediate="true" on input fields?

I saw you are using <p:ajax> . I had some troubles with this. Maybe, if you change to **<f:ajax>** this must works so well.

Primefaces 3.5 SNAPSHOT datatable push (websocket) update

I'm using Mojarra, PF 3.5 SNAPSHOT, Tomcat 7.0.32 and trying to make a datatable update itself when changes have been done by other clients. I'm also using CDF beans along with MyCODI, #ViewAccessScoped.
When I was using 3.4, in-row editing (instead of in-cell editing) and standard #ConversationScoped it was working.

Your table id is staffTable not ba_staffTable

Click on row table is not working when I use AJAX

I have a very strange problem when I try to implement click on table row with AJAX. This is the JS code that I use for click on row:
//for tabs
$(document).ready(function () {
$("#tabs").tabs();
});
$(window).load(function() {
jsf.ajax.addOnEvent(function (data) {
if (data.status === "success") {
$("#tabs").tabs();
}
});
});
$("tr").not(':first').hover(
function () {
$(this).toggleClass('highlited');
// $(this).css("background","#707070");
},
function () {
$(this).toggleClass('highlited');
// $(this).css("background","");
}
);
function highlight(param) {
var row = jQuery(param).parent().parent().children();
row.toggleClass('highlited');
// row.css("background","#707070");
}
var inputs = document.getElementsByTagName("INPUT");
for (var i in inputs) {
if (inputs[i].checked) {
highlight(inputs[i]);
}
}
//for clicking on a row and opening new page
function addOnclickToDatatableRows() {
//gets all the generated rows in the html table
var trs = document.getElementById('form:dataTable').getElementsByTagName('tbody')[0]
.getElementsByTagName('tr');
//on every row, add onclick function (this is what you're looking for)
for (var i = 0; trs.length > i; i++) {
var cells = trs[i].cells;
for(var j=1; j < cells.length; j++){
cells[j].onclick = new Function("rowOnclick(this.parentElement)");
}
}
}
function rowOnclick(tr) {
var elements = tr.cells[0].childNodes;
for(var i = 0; elements.length > i; i++) {
if ((typeof elements[i].id != "undefined") && (elements[i].id.indexOf("lnkHidden") > -1)) {
//opne in a new window// window.open(elements[i].href);
location.href=elements[i].href
break;
}
}
return false;
}

When I remove the AJAX code I can successfully click on datatable row and open a new page. But when I add the AJAX code when I load the table on the first page it works, but when I switch on the second page the JS code is not working. What maybe the problem?
I also call the JS code twice - in the header and at the end of the form.

Use onmouseover.
<h:dataTable onmouseover="addOnclickToDatatableRows();">

How to highlight entire row when the checkbox is selected

I have a JSF datatable. I want to highlight the row when I select the the corresponding check box . How I must edit the JavaScript code to achieve this effect?

I can't really tell where your checkboxes are or what their names are but, I did notice you are using jQuery in your script. I created a quick little jsFiddle demo to show you what you can do with jQuery. In my example, I created a .highlight class where I set the background-color to the color I want. In jQuery, I group all of the checkboxes and attach a .change() handler to them where I toggle the highlight class on/off every click.
Check out the jsFiddle demo
HTML:
<div id="row-1"><input type="checkbox" id="chk-1" />Row 1</div>
<div id="row-2"><input type="checkbox" id="chk-2" />Row 2</div>
<div id="row-3"><input type="checkbox" id="chk-3" />Row 3</div>
<div id="row-4"><input type="checkbox" id="chk-4" />Row 4</div>
CSS:
div
{
display: block;
height: 20px;
padding: 20px;
border-bottom: dashed 1px #000;
}
input
{
margin-right: 10px;
}
.highlight
{
background-color: yellow;
}
jQuery:
$("input[type=checkbox]").on("change", function() {
var $chk = $(this),
num = $chk.attr("id").substring(4),
$row = $("#row-" + num);
$row.toggleClass("highlight");
});
Output:

Well my approach with jQuery is this :
<p:column >
<h:selectBooleanCheckbox onclick="highlight(this)" />
</p:column>
Create .highlighted class in your CSS file:
.highlighted {
background-color: red;
}
And finally actual function:
function highlight(param) {
var row = jQuery(param).parent().parent(); //children() available as well
row.toggleClass('highlighted');
}
You just get the row of the clicked checkbox and handle assigning of the CSS class. Straight and simple.
EDIT: Of course number of .parent() depends on your html elements composition. Edited the function to fit on your case, I've tried it with different composition of elements.

Here is an example of what I've done for getting Javascript to change background colors when checkboxes are checked:
<html>
<body>
<table>
<tr id="changeme1">
<td><input type="checkbox" onclick="highlight('changeme1');" /></td>
<td>Test Box</td>
</tr>
<tr id="changeme2">
<td><input type="checkbox" onclick="highlight('changeme2');" /></td>
<td>Test2</td>
</tr>
</table>
<script>
function highlight(id)
{
object = document.getElementById(id).style.backgroundColor;
if(object == "yellow")
{
document.getElementById(id).style.backgroundColor = "white";
}else{
document.getElementById(id).style.backgroundColor = "yellow";
}
}
</script>
</body>
</html>
