I try to folow exemple from primefaces site .using Dialog Framework - Basic
<p:commandButton value="Options" icon="ui-icon-extlink" action="#{dialogBean.viewCarsCustomized}" />
Bean DialogBean
public class DialogBean {
public String viewCarsCustomized() {
return "dialog:viewCars?modal=true";
}

it is not working,I try to do like this .but every time error
Impossible de trouver un cas de navigation correspondant depuis l'ID

}
But When I do like this the page returend but not as I like
public String viewComposant(){
return "/pagess/pagesComposant/AjoutC.jsf";
}
3.5 version of primefaces
The dialog: navigation outcome prefix from "Dialog Framework" is introduced in PrimeFaces 4.0 and don't work in older versions.
So, you've 2 options:
Upgrade to PrimeFaces 4.0 (note: it's currently still in beta)
Use the "old" approach of dialogWidgetVar.show() in JavaScript or visible="#{someCondition} in JSF. See also the <p:dialog> examples in PrimeFaces showcase.
Update: as per the comment, here's how you could use it with widgetVar approach in JS:
<p:button value="Open dialog" onclick="w_dialog.show(); return false;" />
<p:dialog widgetVar="w_dialog">
<p>Dialog's content.</p>
<p:dialog>
And here's how you could use the visible approach in JSF:
<h:form>
<p:commandButton value="Open dialog" action="#{bean.showDialog}" update=":dialog" />
</h:form>
<p:dialog id="dialog" visible="#{bean.showDialog}">
<p>Dialog's content.</p>
<p:dialog>
with
private boolean showDialog;
public void showDialog() {
showDialog = true;
}
public boolean isShowDialog() {
return showDialog;
}
You can if necessary move <p:dialog> into an include file which you include by <ui:include>.

The p:datatable work fine in standalone but does not work with this situation:
(I am using Primefaces 6.1 and mojarra 2.2.9)
index.xhtml code:
<h:body>
<ui:decorate template="/main.xhtml">
<ui:define name="wrapper">
<c:if test="#{not empty param['action']}">
<ui:include src="/templates/param['action'].xhtml" />
</c:if>
</ui:define>
</ui:decorate>
</h:body>
The value of param['action'] is wrapper.xhtml code:
<body>
<ui:composition>
<h:form>
<p:dataTable var="menu" value="#{customerBean.listMenu}"
rowKey="#{menu.menuId}" selectionMode="single">
<f:facet name="header">
TEST
</f:facet>
<p:column headerText="Id" sortBy="#{menu.menuId}">
<h:outputText value="#{menu.menuId}" />
</p:column>
<p:column headerText="Action" sortBy="#{menu.name}">
<h:outputText value="#{menu.name}" />
</p:column>
</p:dataTable>
</h:form>
</ui:composition>
</body>
The java code:
#ManagedBean(name="customerBean")
#RequestScoped
public class CustomerBean {
#ManagedProperty("#{listMenu}")
private List<Test> listMenu;
#PostConstruct
public void init(){
listMenu = new ArrayList<Test>();
listMenu.add(new Test("123","Test","A1"));
listMenu.add(new Test("124","Test2","A12"));
listMenu.add(new Test("125","Test3","A13"));
}
public List<Test> getListMenu() {
if(listMenu == null){
init();
}
return listMenu;
}
public void setListMenu(List<Test> listMenu) {
this.listMenu = listMenu;
}
}
When I remove <c:if test="#{not empty param['action']}"> and hard-coded /templates/wrapper.xhtml, it works fine.
Is there any missing steps?
Any suggestions would be appreciated, thank you for reading.
I don't know why but when I replace <c:if test="#{not empty param['action']}"> by p:panel, It works fine!
I have a p:dataTable and the selected value is throwing null pointer when Im tring to get it,this situation is after put the datatable inside a modal p:dialog, but if remove the modal atribute works fine.
PD:the modal p:dialog was behid the overlay like this question
Primefaces - AjaxStatus - Dialog is behind the overlay
the answer is not working for me, because Im using primefaces 5.1, so I have to use appendTo="#(body)"
I don´t know if that is important for my problem.
Resume: the null pointer exist if the p:dialog is modal.
Here is my code

You append your <p:dialog> to the body of the html page(see appendTo attribute), as a result it is not included in any <h:form>.
This could be a problem for your <p:dataTable>
Could you place your <h:form id="panotation"> inside of your <p:dialog> and not outside ?
I generated a Primefaces based CRUD website starting from JPA Entities with netbeans and after adjusting the Update dialog to fit my needs I am experiencing several problems. The domain Model is quite easy: I have an entity Invitation which contains several Guests.
#Entity
public class Invitation implements Serializable {
...
#OneToMany(cascade = CascadeType.ALL, orphanRemoval = true, mappedBy = "invitationId")
private List<Guest> guestList;
public List<Guest> getGuestList() {
return guestList;
}
...
}
I have an overview page (list.xhtml) where all the invitations are listed and the user can pick one to edit it.

And the Controller
#SessionScoped
#Named
public class InvitationController implements Serializable {
private Invitation selected; //with getter and setter
}
Now, I think my problem should be in the combination of p:dialog and h:form.
The original generated version of edit.xhtml had the form InvitationEditForm nested within the dialog and not the contrary as I posted above. The problem with that was after clicking editButton the dialog was loaded, but the dataTable was always filled with guests of the first Invitation I selected in my session (more strangely, suppose the first invitation in the session had just a guest A: after selecting an Invitation with 2 guests B and C I got A and B displayed). As the controller was returning the right guestList(), I supposed there was a problem with update and inverting form and display solved this problem..
Unfortunately this didn't solve all the problems, as now the actionListener for addGuestButton and deleteGuestButton doesn't get invoked anymore..
I am really confused: can you please help me to fix my code? Thanks in advance!
I have got some problems with my JSF page, and (probably) with backing bean. I have got own template and I fill the content area with some pages. I have got search page with commandbutton and I would like to get data from database (JPA) and than fill the datatable.
Look at my searchpeople.xhtml:
<ui:composition xmlns:ui="http://java.sun.com/jsf/facelets"
template="template.xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:f="http://java.sun.com/jsf/core">
<ui:define name="content">
<h:form id="sampleform">
<p:accordionPanel activeIndex="-1" id="accordingpanle">
<p:tab title="User options" >
<p:growl id="growl" showDetail="true" showSummary="true"/>
<p:commandButton id="searchbutton" action="#{mb_person.search}" value="Szukaj" update="personsearchresulttable" />
</p:tab>
</p:accordionPanel>
<p:dataTable id="personsearchresulttable" var="person" value="#{mb_person.people}" widgetVar="personTable" style="margin-top: 10px" >
<p:column headerText="Id" style="width:10%">
<h:outputText value="#{person.id}" />
</p:column>
<p:column headerText="Name" style="width:20%">
<h:outputText value="#{person.name}" />
</p:column>
<p:column headerText="Surname" style="width:20%">
<h:outputText value="#{person.surname}" />
</p:column>
<p:column headerText="Company">
<h:outputText value="#{person.companyName}" />
</p:column>
<p:column style="width:4%" headerText="Open">
<h:link outcome="persondetails" value="Open">
<!--<f:param name="personid" value="#{person.id}"/>-->
<f:param name="personid" value="10076"/>
</h:link>
</p:column>
</p:dataTable>
</h:form>
</ui:define>
</ui:composition>
And my backingbean with EJB injection.
#ManagedBean(name="mb_person")
public class MB_Person implements Serializable{
#EJB
private PersonFacade personFacade;
private List<PersonAndCompany> people = new ArrayList<PersonAndCompany>();
public MB_Person() {
}
public List<PersonAndCompany> getPeople() {
return people;
}
public void setPeople(List<PersonAndCompany> people) {
this.people = people;
}
public void search() {
int[] range = {0,5};
setPeople(personFacade.findPersonWithMoreThanXProjects(20));
setPeople(personFacade.findPersonAndCompanyName(range));
for(PersonAndCompany p:people){
System.out.println(p.getName());
}
}
public String goToPersonDatailPage(int id){
return "persondetails.jsf?personid="+id;
}
}
I tried small test and printout all data in method search and I received good results.
Someone can help me how to update dataTable using ajax? In this form I have got an exception
Cannot find component with identifier "personsearchresulttable" referenced from "sampleform:accordingpanle:searchbutton".
Relative client IDs are searched relative to parent NamingContainer component. The <p:accordionPanel> is by itself a NamingContainer. So the relative client ID personsearchresulttable would be searched inside the context of the <p:accordionPanel>. However, it's actually outside the panel, inside the <h:form>.
You need to change the relative client ID to be an absolute client ID.
update=":sampleform:personsearchresulttable"

i have an init() function that returns a list of Domaines needed to populate a datatable, each row of this datatable have two commandlinks one for edit and another for delete, so when i press the edit command link a dialog window apear showing the Domaine information whith the possibility of editing (there is another dialog for adding new domaines), so the problem is when i press edit the init function is called 8 times then the attributes of the adding dialog are setted (even if there is no relation between the thee edit command link and the adding dialog window) after the init function is called again 4 times. i don't understand wh.

i posted long codes cause don't where the problem is coming from.
Your mistake is that you're doing business action in a getter method instead of an action method which is called only once. You should not do business actions in getters. JSF EL uses getters to access bean properties. EL does not cache them when they're ever called once. Getters should solely return bean properties (or at highest do some lazy loading or quick and non-intensive calculation, e.g. a simple sum like return foo + bar;), but definitely not access the database or something.
Move that job to the constructor or #PostConstruct method or any event method of the bean. In this particular case, you likely want to use #PostConstruct to preload the list with help of an #EJB and let the ajax action listener point to the same method as well. In a #ViewScoped bean, this way it's called only once during first request of the view and also called only once when you change the selection.
#PostConstruct
public void init() {
if (choixDirection == 0) {
domaines = domainesService.getAllDomaines();
} else {
Directions direction = directionsService.getDirections(choixDirection);
domaines = domainesService.getDirDomaines(direction);
}
}
public List<Domaines> getDomaines() {
