Here's my XHTML code:
<h:selectOneMenu id="combo" value="#{TeamsHinzufuegenBean.selectedLeagueId}">
<f:selectItems value="#{TeamsHinzufuegenBean.leagues}"
var="league" itemValue="#{league.id}"
itemLabel="#{league.name}"/>
</h:selectOneMenu>
And my bean:
#ManagedBean(name = "TeamsHinzufuegenBean")
#ViewScoped
public class TeamsHinzufügenBean implements Serializable{
private static final long serialVersionUID = 1L;
private List<League> leagues;
private ArrayList<Team> teams = new ArrayList<Team>();
private String teamname;
private int selectedLeagueId=1;
#PostConstruct
public void init() {
leagues = Database.getInstance().getAllLeagues();
for(League l : leagues)
System.out.println(l);
}
public List<League> getLeagues() {
return leagues;
}
public void setLeagues(List<League> leagues) {
this.leagues = leagues;
}
public int getSelectedLeagueId() {
return selectedLeagueId;
}
public void setSelectedLeagueId(int selectedLeagueId) {
this.selectedLeagueId = selectedLeagueId;
}
public ArrayList<Team> getTeams() {
return teams;
}
public void setTeams(ArrayList<Team> teams) {
this.teams = teams;
}
public String getTeamname() {
return teamname;
}
public void setTeamname(String teamname) {
this.teamname = teamname;
}
}
The league-class has an attribute id but if I output the value of selectedLeagueId, it is always 0.
Check if getAllLeagues() contains objects that have an id and that it is correctly set

I have two selectOneMenu one update the other, but the second one do not update its value, and still remains with the first value, despite in any code, this two variables are equal so themselves. Even the valueEventChangeListener returns the estados_eam value. Thanks guys, any help will be very appreciate. Best regards.

There are two solutions:
Update the menu in the listener method in the bean by adding this line:
RequestContext.getCurrentInstance().update("municipios_eam");
Use a p:remoteCommand to update the 2nd menu, so instead of:
<p:ajax listener="#{municipiosMB.handleEstadosChange}" update="municipios_eam"/>
use:
//the remoteCommand should be placed before the first menu
<p:remoteCommand name="updateMuncipios_eam" update="municipios_eam"/>
<h:outputText value="ESTADO:" />
//some more code
<p:ajax listener="#{municipiosMB.handleEstadosChange}" oncomplete="updateMuncipios_eam()/>
my problem is that i can not access to my model's attributs in the dynaForm.
(i'm using spring jsf primfaces).
picture of my xhtml where i have the problem
thank you for help.
here is my code
public class Colonne {
private String nomColonne;
private String typeColonne;
private int index;
public int getIndex() {
return index;
}
public void setIndex(int index) {
this.index = index;
}
public Colonne() {
super();
}
public Colonne(String nomColonne, String typeColonne, int i) {
super();
this.nomColonne = nomColonne;
this.typeColonne = typeColonne;
this.index=i;
}
public String getNomColonne() {
return nomColonne;
}
public void setNomColonne(String nomColonne) {
this.nomColonne = nomColonne;
}
public String getTypeColonne() {
return typeColonne;
}
public void setTypeColonne(String typeColonne) {
this.typeColonne = typeColonne;
}
}
here is my managedBean
public class MonBean implements Serializable{
private static final long serialVersionUID = -5773011533863117274L;
private GestionTableImpl gestionTable;
private Table table;
private DynaFormModel model;
public static long getSerialversionuid() {
return serialVersionUID;
}
public DynaFormModel initialize() {
System.out.println("1");
model = new DynaFormModel();
Colonne col = new Colonne("a","b",0 );
DynaFormRow row = model.createRegularRow();
row.addControl(col, "columnName");
row.addControl(col, "columnType");
row.addControl(col, "add");
col = new Colonne("c","d",1 );
row = model.createRegularRow();
row.addControl(col, "columnName");
row.addControl(col, "columnType");
row.addControl(col, "add");
col = new Colonne("e","f", 2);
row = model.createRegularRow();
row.addControl(col, "columnName");
row.addControl(col, "columnType");
row.addControl(col, "add");
return model;
}
public DynaFormModel getModel() {
return model;
}
public void setModel(DynaFormModel model) {
this.model = model;
}
public Table getTable() {
return table;
}
public void setTable(Table table) {
this.table = table;
}
}
You are assigning #{monBean.initialize()} to dynaForm value attribute, use #{monbean.model} instead.
Also, you have to change initialize method of MonBean class to return void, and annotate this method with #PostConstruct.
This way it won't fail when executing and your IDE wn't complain about it.
In my xhtml there are 3 input field which calculate remaining day of two <p:calendar> dates. In next step I want to store calculated remaining day to MY DB.
<p:dataTable styleClass="vtable" editable="true" var="user"
editMode="cell" value="#{userBean.employeeList}">
<p:column styleClass="columntd" headerText="#{text['user.startedDate']}">
<p:calendar widgetVar="fromCal" value="#{vacationBean.vacation.beginDate}">
<p:ajax event="dateSelect" listener="#{dayDiffBean.fromSelected}"
update="diff" />
</p:calendar>
</p:column>
<p:column styleClass="columntd"
headerText="#{text['user.finishedDate']}">
<p:calendar widgetVar="toCal" value="#{vacationBean.vacation.endDate}">
<p:ajax event="dateSelect" listener="#{dayDiffBean.toSelected}"
update="diff" />
</p:calendar>
</p:column>
<p:column styleClass="columntd"
headerText="#{text['employee.remainingdays']}">
<p:inputText id="diff" styleClass="daysNumber"
value="#{dayDiffBean.diff}" />
</p:column>
</p:dataTable>
<h:commandButton styleClass="sndbutton1"
value="#{text['employee.send']}" action="#{vacationBean.addVac}"/>
I used value="#{dayDiffBean.diff} to get remaining day and now I also want to use my vacationbean to store remaingday to my db using like this : value="#{vacationBean.vacation.balanceDay}"
But I cant use 2 value in inputtext field like this:
<p:inputText value="dayDiffBean.diff" value1="vacationBean.vacation.balanceDay">
How can i solve this problem?
This is my vacation bean code:
#ManagedBean(name="vacationBean")
#ViewScoped
public class VacationBean implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private Date vEndDate;
private boolean selected;
private Date vStartDate;
private Date createdDate;
private String isNobody;
Requestrelax vacation;
Employee e;
Calendar javaCalendar = null;
private short balanceDay;
#EJB
VacationLocal vacations;
#ManagedProperty(value="#{loginBean.userId}")
Integer userId;
#EJB
EmployeesLocal employees;
#PostConstruct
public void init(){
System.out.println("0");
//System.out.println("STATrtsg >> . "+ diff.getDiff());
vacation=new Requestrelax();
e=employees.getEmployee(userId);
vacation.setEmployee(e);
System.out.println("balanday is:"+balanceDay);
}
public void addVac(){
System.out.println("1");
javaCalendar = Calendar.getInstance();
Date currenDate=Calendar.getInstance().getTime();
vacation.setCreatedDate(currenDate);
vacation.setBalanceDay(balanceDay);
vacations.addEmployeeVacation(vacation);
}
public Integer getUserId() {
return userId;
}
public void setUserId(Integer userId) {
this.userId = userId;
}
public Employee getE() {
return e;
}
public void setE(Employee e) {
this.e = e;
}
public Requestrelax getVacation() {
return vacation;
}
public void setVacation(Requestrelax vacation) {
this.vacation = vacation;
}
public Date getvEndDate() {
return vEndDate;
}
public void setvEndDate(Date vEndDate) {
this.vEndDate = vEndDate;
}
public Date getvStartDate() {
return vStartDate;
}
public void setvStartDate(Date vStartDate) {
this.vStartDate = vStartDate;
}
public short getBalanceDay() {
return balanceDay;
}
public void setBalanceDay(short balanceDay) {
this.balanceDay = balanceDay;
}
public Date getCreatedDate() {
return createdDate;
}
public void setCreatedDate(Date createdDate) {
this.createdDate = createdDate;
}
public String getIsNobody() {
return isNobody;
}
public void setIsNobody(String isNobody) {
this.isNobody = isNobody;
}
}
And daydiffbean code :
#ManagedBean(name="dayDiffBean")
#SessionScoped
public class DayDiffBean implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private Date from;
private Date to;
private String diff="";
private final long oneDay=1000*60*60*24;
public void fromSelected(SelectEvent event){
from=(Date) event.getObject();
calDiff();
}
public void toSelected(SelectEvent event){
to=(Date) event.getObject();
calDiff();
}
public void calDiff(){
if(from==null||to==null){
diff="N/A";
return;
}
diff=(to.getTime()-from.getTime())/oneDay+"";
}
public String getDiff() {
return diff;
}
public void setDiff(String diff) {
this.diff = diff;
}
public void setFrom(Date from) {
this.from = from;
}
public Date getFrom() {
return from;
}
public Date getTo() {
return to;
}
public void setTo(Date to) {
this.to = to;
}
}
From the code, one way to add balanceDay to your vacationBean is by passing the diff string as a parameter to addVac() method (notice action in the second line):
<h:commandButton styleClass="sndbutton1" value="#{text['employee.send']}"
action="#{vacationBean.addVac(dayDiffBean.diff)}"/>
Then, for your VacationBean.addVac():
// 'diff' is now being passed in as a parameter
public void addVac(String diff) {
System.out.println("1");
javaCalendar = Calendar.getInstance();
Date currenDate=Calendar.getInstance().getTime();
vacation.setCreatedDate(currenDate);
vacation.setBalanceDay(balanceDay);
// UPDATED
// so now you can set balanceDay
setBalanceDay(Short.parseShort(diff));
vacations.addEmployeeVacation(vacation);
}
I'm new to JSF, and stuck in a problem.
I have a selectOneMenu for displaying the list of countries. When the user selects one of the country, there's another selectOneMenu having the cities (=regions in my case) should be auto-populated.
I tried several iterations for doing the same but didn't help.
Please let me know if anything else is also needed to help me. Would really appreciate it.
UPDATE:
Here's the code after adding listener:
<p:outputLabel for="countryRegistration">#{msg['country']}:</p:outputLabel>
<p:selectOneMenu id="countryRegistration" value="#{mbcActor.geoData.country}" style="width:120px;" >
<f:attribute name="country" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCountry']}" itemValue=""/>
<f:selectItems value="#{geoLists.countryList}" var="country" itemLabel="#{country.name}"/>
<p:ajax listener="#{mbcActor.geoData.updateRegions}" render="cityRegistration"/>
</p:selectOneMenu>
<p:message for="countryRegistration"/>
<p:outputLabel for="cityRegistration">#{msg['city']}:</p:outputLabel>
<p:selectOneMenu id="cityRegistration" value="#{mbcActor.geoData.region}" style="width:120px;">
<f:attribute name="regions" value="java.util.List" />
<f:converter converterId="ViewScopedObjectConverter"/>
<f:selectItem itemLabel="#{msg['selectCity']}" itemValue=""/>
<!--<f:selectItems value="#{geoLists.regionForCountry}" var="region" itemLabel="#{region.name}"/>-->
<f:selectItems value="#{geoLists.getRegionForCountry(country)}" var="region" itemLabel="#{region.description}"/>
</p:selectOneMenu>
<p:message for="cityRegistration"/>
But it says:

Your <p:ajax> tag uses the render attribute, which isn't predefined. The attribute you want is update.
supposing that registrationHelper.newActor is an instance of of a Managed Bean, I think it's probably not initialized. Why don't you make sure it is, by creating it on RegistrationHelper's PostConstruct, or even get it through a method like
public AbstractActor createNewActor() {
newActor = new AbstractActor();
return newActor;
}
<ui:param name="mbcActor" value="#{registrationHelper.createNewActor}"/>
I am displaying a ProductList, which is made up of Product objects. The Product has attributes of type int, string, string, and int. The data is being pulled from the database and I build a ProductList. The data is in the database, I can see it, but when I display the table, the table shows 0's for the 2 int columns, and blanks in the String columns. Here is the ProductList:
#ManagedBean
public class ProductList {
private ArrayList<Product> allProducts;
public ProductList(){
allProducts = DatabaseConnector.getAllProducts();
}
public ArrayList<Product> getAllProducts(){
return allProducts;
}
public void setAllProducts(ArrayList<Product> allProducts){
this.allProducts = allProducts;
}
}
And here is the Product bean:
#ManagedBean
public class Product {
private int id;
private String productName;
private String description;
private int quantity;
public Product() {
}
public void setId(int id) {
this.id = id;
}
public void setProductName(String productName) {
this.productName = productName;
}
public void setDescription(String description) {
this.description = description;
}
public void setQuantity(int quantity) {
this.quantity = quantity;
}
public int getId() {
return id;
}
public String getProductName() {
return productName;
}
public String getDescription() {
return description;
}
public int getQuantity() {
return quantity;
}
}
Should I change the scope of the beans?
Add scope annotation to your bean , for example #RequestScoped or #ViewScoped
otherwise it will be the default scope which is #NoneScoped
