I have a view that display a list of users, from this view I can go to another view of "details" of any selected user. In the details view I need to select some values from 2 select list and then in the backed bean take these values, and add them to an user to finally store (update) the user in the database. These are my methods in the "user Bean".
With this method I get the user id from the "list of users view" and retrieve the user from the database to display its info on the details view.
public void getParam(){
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
//Obtener parametros del request
Map<String, String> parameterMap = (Map<String, String>) externalContext.getRequestParameterMap();
Long param = Long.valueOf(parameterMap.get("id_usuario"));
System.out.println(param);
this.setU(controlador.getUser(param));
}
With this method I set the values from the select list to an object and then I add this object to the user, finally I save it on the database.
public void setPrivilegio(){
System.out.println("hola");
Privilegio pri=new Privilegio();
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
//Obtener parametros del request
Map parameterMap = externalContext.getRequestParameterMap();
Agrupacion agrupacion= (Agrupacion)parameterMap.get("agrup");
System.out.println(agrupacion.getNombre());
Rol rol = (Rol)parameterMap.get("rols");
System.out.println(rol.getNombre());
System.out.println(""+rol.getNombre()+" "+agrupacion.getNombre());
pri.setRol(rol);
pri.setAgrupacion(agrupacion);
pri.setActive(true);
this.getU().addPrivilegio(pri);
controlador.saveUsuario(this.getU());
}
This is my view:

When I click on my commandbutton called "Asignar" that calls the method setPrivilegio(), I get this error:
java.lang.NumberFormatException: null
at java.lang.Long.parseLong(Long.java:404)
at java.lang.Long.valueOf(Long.java:540)
at cl.uchile.sti.bean.UsuarioBean.getParam(UsuarioBean.java:114)
The tables in the view shows all the info, but when I want to call the method that add the selected items to the user and save it on the database (setPrivilegio) I get this error.
How is this caused and how can I solve it?
This is my full "user bean":

Bad getter!
public Usuario getU() {
getParam();
return u;
}
The getter above is a very bad idea. You've said it yourself that the variable makes it into the usuario backing bean(this I doubt). It is just plain wrong to perform business logic inside a getter because of inconsistencies (like you're experiencing) and the fact that the getter is called multiple times during a request. There are more elegant and cleaner ways to pass and initialise parameters between JSF pages.
private Usuario u=new Usuario(); is also a bad idea. Why is this necessary when you have
this.setU(controlador.getUser(param));
All that should happen inside your #PostConstructor
#PostConstruct
public void init() {
controlador=new usuarioController();
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext externalContext = facesContext.getExternalContext();
//Obtener parametros del request
Map<String, String> parameterMap = (Map<String, String>) externalContext.getRequestParameterMap();
Long param = Long.valueOf(parameterMap.get("id_usuario"));
System.out.println(param);
this.setU(controlador.getUser(param));
}
The getter should just be plain
public Usuario getU() {
return u;
}
The cause of this error is that parameterMap.get("id_usuario") is null. You should investigate how you pass this parameter from the UI to the backing bean.

You need to set the rowKey attribute on the <p:dataTable/> to properly enable row selection. The rowKey attribute should be set to a unique identifier for the entity in your datatable, like the primary key attribute. From your sample, it'll look something like:
<p:dataTable value="#{userManagedBean.dataModel}" rowKey="#{user.userId}" var="user" pagination="true" rows="5" selection="#{userManagedBean.selectedUser}" selectionMode="single">
I am using #ViewScoped Bean for small CRUD application I have a edit and view page but when I click buttons (edit) it will render edit form. After edit form appears the save button or cancel button does not call the function but renders the whole page. The actionListener's function is not called at all and everthing is initialized. Is something wrong with my bean and page?? I am using JSF 2 with richfaces and facelet.

In ViewScope, once the view is built, for example form.xhtml, its data will last as long you do not go away from this view. To stay in the same view you should call methods that has return type void (which are usually used in actionListener property) or return null, in case of returning an outcome for navigation.
Method expression
In your case your methods are void but instead of passing it to the action listener you're calling it in the view.
Try changing similar code like this:
<a4j:commandButton value="SAVE" actionListener="#{legendbean.saveLegend()}" render="mainPnl"/>
To this:
<a4j:commandButton value="SAVE" actionListener="#{legendbean.saveLegend}" render="mainPnl"/>
As actionListener property already expects a method expression.
Form inside dataTable
Also I noticed you have a form inside your dataTable. That could lead to strange behavior because your form has an id it will be repeated in the resulting page. For that you should try placing the form outside the dataTable.
Even better you could have only one form enclosing the entire code as nested forms are invalid HTML code.
I would suggest you check your legendTemplate.xhtml against nested forms too.
Bean construction
In order to initialize your bean state it is recommended to use a #PostContruct method instead of the bean constructor.
Try changing from this:
public LegendController() {
legendDTO = new LegendDTO();
legendDTO.getList().add(new Legend());
}
To this:
#PostConstruct
public void reset() {
legendDTO = new LegendDTO();
legendDTO.getList().add(new Legend());
}
And delete your constructor.
Your bean data should be kept as long as you're in the same view (aka .xhtml page).
I hope it helps.
I am having the same problem. I don't think the answers above really address the question. He is not having a problem as a result of submitting any forms - pressing those buttons themselves results in the whole page re-rendering, which means that the reference to the view state is already gone before the button is pressed. This is what I am observing as well. For me, it only happens when there are a lot of large search results, and simply re-submitting the same search I just did re-renders the page (without executing the search). I believe the problem has to do with a limit on the amount of data that can be passed to the server in a form: in view scope, all of the data is serialized and passed around in one long hidden value as a value in the form. If that value is too long the server won't accept it and, therefore, will not remember the previous state.
I know this is not definitive, but this is only thread out there on this problem I can find so I hope it helps shed light for others or inspires better information. If you have something more definitive please let us know.
Edit: I am convinced now that this was the problem. My model bean had a reference to a file blob. Once I replaced that reference with a boolean (only needed to know if it existed) the problem went away. Try passing around references to your DTOs/DAOs instead of the objects themselves, or mark them as "transient" where you don't need them to persist. Or, if possible, lighten the objects as I did.
Did you try to return null for functions saveLegend() and cancel() instead of returning empty string?
public String saveLegend() {
---------
return null;
}
public String cancel() {
----------
return null;
}
Return can also be void for ajax request. But if I remember it correctly for richfaces returning null is the only solution. Give it a try. :)
The cancel() works as it reinitialize the bean.
As answered by Bento you cannot pass values using actionListener. Use action instead.

There is something i'm doing wrong?
its because of the attribute type="button" which is not firing the actionlistener.
when you declare this attribute (type="button") its not a p:commandButton anymore.
type="button" is push button purposes, it does not do any action or submit the form
try to remove type="button" attribute. it'd fire the actionlistener.
<p:commandButton id="cbViewExcluir"
image="ui-icon-circle-close"
onclick="dlgExcluir.show()"
title="Excluir"
update=":frmExcluir">
<!-- This is not working properly -->
<f:setPropertyActionListener value="#{atual}" target="# {publicoBean.publicoSelecionado}" />
</p:commandButton>
lemme know if this helps :)
I have a data table that will display a detail dialog on row select event. However, the dialog does not show any values of the selected object. I can see that the selected object is properly set during debug session.
The table consists of rows of students and it is suppose to display a popup dialog showing detailed information on row selection event.
The StudentBean:
#Named(value = "studentBean")
#SessionScoped
public class StudentBean {
#Inject
private UserFacade userFacade;
private List<User> studentList;
private User selectedStudent;
public StudentBean() {
}
#PostConstruct
public void init() {
studentList = userFacade.findAll();
}
public List<User> getStudentList() {
return studentList;
}
public void setStudentList(List<User> studentList) {
this.studentList = studentList;
}
public User getSelectedStudent() {
return selectedStudent;
}
public void setSelectedStudent(User student) {
this.selectedStudent = student;
}
public void onRowSelect(SelectEvent event) {
}
public void onRowUnselect(UnselectEvent event) {
//FacesMessage msg = new FacesMessage("Student Unselected", ((User) event.getObject()).getFirstName());
//FacesContext.getCurrentInstance().addMessage("messages", msg);
}
}

I'm following the Car data table example from the Primefaces Showcase page. It seems so simple there but I can't seem to display the selectedStudent information no matter what I do. The dialog shows up fine but the firstName and lastName values are empty.
I tried the following:
Putting the dialog into another form
Use process="#form"
Use process=":studentForm:studentDetail"
What am I doing wrong?
Primefaces 3.3.1,
Glassfish 3.1.2
I removed global="true" immediate="true", unused listeners
from p:ajax, synchronized rowKey="#{student.id}"
with expression from "Student ID" column and populated
studentList inside #PostConstruct init() function not knowing how yours userFacade code is, and it works.
I have one datatable created with a PrimeFaces 3.3 datatable. This table is populated from a database.
On a row selection, I populate similar fields for editing. Once edited, I want to write to the db. Similarly, I want to be able to create a new record in text items and once the user saves it the datatable to be refreshed.
Data selection works fine, however, when I cant figure out way for add/edit/delete, different errors come with different approach and I have tried all methods I could find on Google. These errors are some time logical errors and some times nullpointerexception or class initiation errors. I have tried over a dozen examples available on net for jtable + crud but seems nothing works fine for me.
For example, data is displayed in data table and instant selection in the text fields is also done but when i click add button, nothing happens, I expect fields in 'edit properties' panel to be cleared, sometimes I get a NullPointerException, even if I modify values in text items and press save, values are not written. When I debugged, I found error coming in em.getTransaction().begin line.
If I use em.joinTransaction it again throws an error on the commit statement. Since I am new to Java EE I think I am making some terrible mistakes.
I will appreciate if some one can give some example of a similar scenario: jtable + bound fields + add / edit / delete operations.
