I have a datatable which has add edit delete and filter operations.
All the operations are working fine on the database but the datatable is not updating correctly after an add operation.
It is updated correctly after the 1st add operation.
when I add 2nd row the datatable is updated but the row which was added first is replaced with the row which was added 2nd but in the db they are updated correctly.
similarly when I add a 3rd row the 1st row is replaced with the 3rd row.
Software stack used in the CRUD dataTable application are :- PrimeFace 3.4.2,JSF 2.1,NetBeans 7.2.1,Java 1.6.0_37 GlassFish 3.1.x,MySql 5.x
This is my code.

I have primefaces command button multiple update problem. Command button is inside a form and datatable is not.
I have tried:
update=":datalist1,form1"
update=":datalist1 form1"
update="datalist1 form1"
update=":#{p:component('datalist1')},form1"
form1 updates every time but still dattable does not update
Version info:
primefaces: 5.3
jsf: org.glassfish 2.3.0-m04
spring: 4.2.3
and I use cdi for controller beans

I have researched about primefaces command button update but all advices did not worked for me. Thank you in advance
It seems to me that the newly created personel it never added to the list. So you must for example say
personels.add(personel);
or
personels=personelService.findAll();
in createPersonel(), or set personels to null and do a lazy load in getPersonels().
I have a table p:dataTable. When I select an item, it's refresh another p:dataTable with associed values.
It's works fine. But when I select an item in the second table, the page (xhtml) don't get the value from the bean.
In debug mode I see that the value is updated on bean, but acessing #{bean.value} is always null.
Where is the codes:
<h:form id="form">

I'd say you just need to update the dialogs content from the p:ajax in the second table - just as you update the second datatable, when you select in the first.
So add id="dialog" to the dialog, and make the p:ajax in the second table
<p:ajax event="rowSelect" listener="#{alunos.onRowSelectDisciplina}" update=":form:dialog" oncomplete="PF('dDialog').show()" />
Or omit the new id and just do update=":form:detail".
I am currently developing an application with JPA2, Spring 3, MyFaces 2.1 and Primefaces 4.0 RC1.
I developed a simple page with one datatable using pagination feature of primefaces, but when I click on page number (bottom or header), it simply doesn't work. No exception or javascript error is shown.
I've tested both in Chrome and Firefox. Same problem.
Here my code:
#ManagedBean
#ViewScoped
public class MeusCelularesTitularMB extends AbstractMB implements Serializable {
private static final long serialVersionUID = 5446365969371398743L;
private static final Logger logger = LogManager.getLogger(MeusCelularesTitularMB.class);
private CadastroGeral loggedUser;
private List<LinhaCelularTitular> listaCelularesTitular;
#PostConstruct
public void init() {
try {
this.loggedUser = getCadastroGeralService().loadUser(getAuthenticatedUser());
this.listarMeusCelularesTitular();
} catch (ServiceException e) {
logger.error("Erro ao consultar banco de dados", e);
throw new RuntimeException(e);
}
}
private void listarMeusCelularesTitular() {
try {
this.listaCelularesTitular = getLinhaCelularTitularSevice().getLinhasCelularesPorReponsavel(this.loggedUser.getMatricula());
} catch (ServiceException e) {
logger.error("Erro ao consultar banco de dados", e);
throw new RuntimeException(e);
}
}
private static CadastroGeralService getCadastroGeralService() {
return Faces.evaluateExpressionGet("#{cadastroGeralService}");
}
private static LinhaCelularTitularService getLinhaCelularTitularSevice() {
return Faces.evaluateExpressionGet("#{linhaCelularTitularService}");
}
public List<LinhaCelularTitular> getListaCelularesTitular() {
return listaCelularesTitular;
}
public void setListaCelularesTitular(List<LinhaCelularTitular> listaCelularesTitular) {
this.listaCelularesTitular = listaCelularesTitular;
}
}

If you need some more information, please let me know.
Found the solution! Thanks to #XtremeBiker for the hints.
The <p:ajaxStatus onstart="statusDialog.show();" onsuccess="statusDialog.hide();"/> is referencing a dialog box that I forgot to add in the XHTML. So I added the code below and it worked.
<p:dialog modal="true"
widgetVar="statusDialog"
header="Aguarde..."
draggable="false"
closable="false"
resizable="false"
width="245"
height="25" >
<div align="center">
<p:graphicImage value="/resources/images/ajax-loader.gif" />
</div>
</p:dialog>
I use this code to block screen when a ajax request is processing.
Thanks again.
i have these simple pages:
list.xhtml
<h:form id="form">
<h:dataTable value="#{testBean.model}" var="elem">
<h:column>
<f:facet name="header">code</f:facet>
#{elem.code}
</h:column>
<h:column>
<f:facet name="header">description</f:facet>
#{elem.description}
</h:column>
<h:column>
<f:facet name="header">action</f:facet>
<h:commandButton action="#{testBean.edit(elem)}" value="edit"/>
</h:column>
</h:dataTable>
</h:form>
edit.xhtml
<h:form id="form">
<h:panelGrid columns="2">
<h:outputLabel value="code"/>
<h:inputText value="#{testBean.selection.code}"/>
<h:outputLabel value="description"/>
<h:inputText value="#{testBean.selection.description}"/>
</h:panelGrid>
<h:commandButton action="#{testBean.update}" value="update"/>
</h:form>
and this bean:
#ManagedBean
public class TestBean implements Serializable
{
private static final long serialVersionUID = 1L;
#EJB
private PersistenceService service;
private Object selection;
private List<UnitType> model;
#PostConstruct
public void init()
{
model = service.findAll(UnitType.class);
}
public String edit(Object object)
{
System.out.println(Tracer.current(object));
setSelection(object);
return "edit";
}
public String update()
{
System.out.println(Tracer.current(selection));
return "list";
}
// getters and setters
}
so the table is rendered, when i click one of the "edit" buttons it navigates to "edit.jsf" showing filled input,
but when i click the "update" buttons it gives me this error:
javax.el.PropertyNotFoundException: /test2/edit.xhtml #27,54 value="#{testBean.selection.code}": Target Unreachable, 'null' returned null
note that i know how to implement a #ViewScoped interface to manage CRUD operations, but this is a simple proof of concept that i need to better understand JSF lifecycle.
so i want "testBean" to be #RequestScoped
UPDATE trying with f:viewParam, still not understanding...

if i press "edit" button it goes to edit page, but selection is null and no message is showed.
if i press "edit2" button it goes to edit page, but selection is null, showing required message and the url is edit.jsf?entity=
what am i doing wrong?
As my understand, when your second request come to testBean, selection Object is null. If you run this with session bean you may not get this error.
The way I see it, there's no clean way to achieve what you want.
I'll suggest you simply pass around an Id attr between requests as a simple request parameter. So in your post constructor, check if the parameter value is set and based on that, perform a look in your persistence layer.
Alternatively, using the setup you already have, bind the:
<h:inputText value="#{testBean.selection.code}"/>
component to your backing bean and call getValue() on it when necessary. Either way, still untidy.
If you find any other way, please let us know.
Finally I found a way: data will be in a long scope, bean in short.
Note that this is just a proof of concept, not a real use case. And be aware, when dealing with #RequestScope beans, of PrimeFaces lazy DataTable model scope

Im using primefaces version 3.1.1, Mojarra 2.1.3, Netbeans 7.0.1, Glassfish Server 3.1.
My test application is using a facelet template with top, left, content, right and bottom layout with raw divs and css. After user logs in with container managed jdbcrealm, they will be presented with the main index.html which use the said template.
I put a navigation menu on the left panel which will subsequently update center panel content with ajax upon clicking menuitem. The center panel will be updated dynamically in <ui:include> by using sessionScoped NavigationBean.
In one of the page clientList.xhtml, I put a <p:dataTable> with a button to view the detail by popping up a <p:dialog>. Im using a viewCoped bean to hold the data list displayed on the dataTable.
The problem is, when I click on the button to select a row in the last colum of every row, the dialog does not appear at all, and my p:ajaxStatus gif image kept on rolling unendingly. When I debug the program with netbeans, I notice the constructor is called again and the previous instance is gone after clicking the button.
This is my index.xhtml using facelets template.

This is my Backing Bean.

The backingBean is reinitialized the first time I click on the view detail commandButton in the last column of the dataTable in clienList.xhtml. And the dialog does not display at all. But after pressing F5. The dialog can be displayed but without any content, the only thing displayed in the dialog is the label outputText but not the bean values, they are empty. Sorry for newbie question. I will be extremely glad if anyone could advise what im doing is wrong, and maybe a little advise on the navigation and whether my strategy of displaying everything in index.xhtml (so I only have 1 view id all the time which is index.xhtml, right?) is right.
This may be the issue with your PrimeFaces dialog that you have an h:form surrounding the p:dialog. I have noticed the PrimeFaces dialog does not work properly when a child of a form element.
Try placing this dialog form inside of the contents of the dialog.
<p:dialog id="clientDialog" header="Client Detail" widgetVar="clientDialog" resizable="false" showEffect="explode" hideEffect="explode">
<h:form id="formdialog" prependId="false">
<h:panelGrid id="display" columns="2" cellpadding="4">
