Thank you very much.
Yes its spanish please bear with me!
Equipos == Teams;
Partidos == Matches;
Campeonatos == Championships;
This exception is related to the view, not to the model. The exception is telling that you've set a component ID with the value partidosPK.idEquipo like as follows:
<h:someComponent id="partidosPK.idEquipo">
However, this ID is illegal as per the rules. It contains a dot .. Remove it or replace by _ or -. The rules are the same as for the HTML/CSS identifiers.
In CSS, identifiers (including element names, classes, and IDs in selectors) can contain only the characters [a-zA-Z0-9] and ISO 10646 characters U+00A1 and higher, plus the hyphen (-) and the underscore (_); they cannot start with a digit, or a hyphen followed by a digit.

How to populate options of h:selectOneMenu from database?
(5 answers)
Closed 7 years ago.
I have two tables into database: Book and Category. Now I want to make page where user can add books into Book table, but with selecting appropriate category from Category table.
I can add book into table but I can not save value category in Book table.
[
As you can see category from Book table is Foreign key with category_id from Category table.
Here are model classes:
Book model
#Entity
#Table(name = "book")

public void setBookId(Integer bookId) {
this.bookId = bookId;
}
public String getName() {

public void setName(String name) {

return false;
}
return true;

this.categoryId = categoryId;

public void setCategoryId(Integer categoryId) {

Now I have JSF page where I add bookes to database. I have dropdown lists that loads categories into it. User should select one category and save book to table.
This is code from JSF addBook page.
<p:layoutUnit position="center">
<h:form>
<p:inputText value="#{bookBean.name}" a:placeholder="Ime knjige"></p:inputText><br/>
<p:inputText value="#{bookBean.description}" a:placeholder="Opis knjige"></p:inputText><br/>
<p:selectOneMenu value="#{bookBean.category}">
<f:selectItems value="#{categoryBean.allCategories}" var="c"
itemLabel="#{c.name}" itemValue="#{c.categoryId}"/>
</p:selectOneMenu>
<b/><b/>
<p:commandButton value="Dodaj knjigu" action="#{bookBean.addBook()}"/>
</h:form>
</p:layoutUnit>
As you can see I use selectOneMenu with value bookBean.category and then I am not sure what I need to set as value in selectItems.
This is BookBean code:
#ManagedBean
#ApplicationScoped
public class BookBean {
String name;
String description;
int categoryId;
Category category;
#Inject
public BookEJB bookEJB;
public void addBook(){
Book book = new Book();
book.setName(name);
book.setDescription(description);
book.setCategory(category);
bookEJB.addBook(book);
}
public List<Book> getAllBooks(){
return bookEJB.getAll();
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public int getCategoryId() {
return categoryId;
}
public void setCategoryId(int categoryId) {
this.categoryId = categoryId;
}
public Category getCategory() {
return category;
}
public void setCategory(Category category) {
this.category = category;
}
public BookEJB getBookEJB() {
return bookEJB;
}
public void setBookEJB(BookEJB bookEJB) {
this.bookEJB = bookEJB;
}
}
Try this :
<f:selectItems value="#{categoryBean.allCategories}" var="c"
itemLabel="#{c.name}" itemValue="#{c}"/>
Listed item name would be category name and category will be assigned to bookBean.category and this can be set as book category and persisted.
Hope this helps.
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}"/>
My web application is a CRUD web application based on JSF 2.0 / JPA using Java EE 5 and JDK 1.6. Running on Glassfish 3.1. The IDE is Netbeans 7.0. (I do not use EJB, nor CDI).
THE PROBLEM
What I can achieve now is perform CRUD on my entities. Which is fine. For each entity I have:
List.xhtml (LIsting all Datamodel items for that entity in datatable)
Create.xhtml (A form to create a new item)
View.xhtml (a form to view an item)
Edit.xhtml (a form to edit an item)
Structure
entities package: entities.
jpa.controllers package: JPA controllers (Javax persistence..).
jsf package: a managed bean for each entity (session Scoped).
But the main problem is parent-leaf navigation. I want my webapp to do the same thing as the Demo application Agile ScrumToys that comes along shipped with Netbeans 7.0. or the demo webapp from SpringFuse, otherwise :
E.G: When you display a list of WRITERS in a you have the last <h:column> where you put three <h:commandLink /> for editing, viewing and deleting the selected row.
What I intend to do is to add another in the same column that allows me to view a collection of child objects related to that selected row.
Hence, I want to show the list of BOOKS written by a given WRITER.
WRITER 1 ---------- * BOOK (one-to-many) relationship.
When the user clicks on the
<h:commandButton action="#{someManagedBean.showBooksForWriter}" value="#{i18n.listBooks}" /> it forwards him to the /book/List.xhtml (list of the selected WRITEr row should appear). And so on, from the book datatable, from a given row, I click on <h:commandLink action="#{someManagedBean.showReferencesForBook}" value="List of Book References"/> to get the list of references for the given book.
A given hint by #Matt was to use a method in the book managed bean:
public showBooksForWriter(Writer writer) {
// TODO: get the selected writer
// Get the list of books for the selected writer
return "/book/List"; // Outcome
}
And in the view :
<h:datatable value="#{writerController.items}" var="w">
.....
<h:column>
<h:commandButton action="#{bookController.showBooksForWriter(w}" value="Show Books For Writer"/>
</h:column>
....
</h:datatable>
But I could not figure how to (DataModel is driving mad). So if anyone could help! It would be very appreciated!
Below is my code

Hi All
i wonder how to select between many to one relational
i have two table Sub_category and Items
sub category is own of relational, it contain list of Items
Two class follow:
#Entity
#Table(name = "item")
#NamedQueries({
#NamedQuery(name = "Items.findAll", query = "SELECT i FROM Items i"),

#NamedQuery(name = "Items.findByItemDescribe", query = "SELECT i FROM Items i WHERE i.itemDescribe = :itemDescribe"),
#NamedQuery(name = "Items.findByImg", query = "SELECT i FROM Items i WHERE i.img = :img"),
#NamedQuery(name = "Items.findByInstock", query = "SELECT i FROM Items i WHERE i.instock = :instock"),

i have stateless bean for handle subcat such as:
#Stateless
#LocalBean
public class SubCatDAO {
#PersistenceContext(unitName = "mcGrawLibPro-ejbPU")
private EntityManager em;
public List<SubCat> retrieveAllSubCat(){
return em.createNamedQuery("SubCat.findAll").getResultList();
}
public SubCat updateSubCat(SubCat sc){
return em.merge(sc);
}
public void deleteSubCat(SubCat sc){
em.remove(em.merge(sc));
}
public SubCat addSubCat(SubCat sc){
em.persist(sc);
return sc;
}
public void persist(Object object) {
em.persist(object);
}
public List<Category> retrieveAllCat(){
return em.createNamedQuery("Category.findAll").getResultList();
}
public List<Items> getAllItemsSubCat(SubCat sub){
em.refresh(em.merge(sub));
List<Items> items = sub.getItemList();
ArrayList<Items> toReturn = new ArrayList<Items>(items.size());
for(Items iItem : items){
toReturn.add(iItem);
}
return toReturn;
}
// Add business logic below. (Right-click in editor and choose
// "Insert Code > Add Business Method")
}
as you can see in stateless bean of subcat , i have written one method return List
and in JSF Managed Bean of subcat i write one method return List to view (JSF)
such as:
public List<Items> getAllItemsSub(){
return subCatDAO.getAllItemsSubCat(sub);
}
(subCatDAO is Stateless bean)
also in JSF Managened Bean of subcat i inital subcat follow:
public BeanConstructor(){
sub = new SubCat(1);
}
my problem is in view (JSF ) i was print list of items to show to user , but i can't get anything,i just see blank,
my code sample :
<h:ouputText value="#{bean.allItemSub.itemid}"/>
when i print bean.allItemSub it return [] <===
why it empty?
I don't really understand your implementation of the getAllItemsSubCat(SubCat sub) method in your EJB. I would rewrite it like this.
First, add a named query to find Items for given a SubCategory:
#NamedQuery(name = "Items.findBySubCat",
query = "SELECT i FROM Items i WHERE i.subCat = :subCat")
And rewrite the EJB method as follow:
public List<Items> getAllItemsSubCat(SubCat sub){
return em.createNamedQuery("Items.findBySubCat").setParameter("subCat", sub)
.getResultList();
}
Then, activate SQL logging (at the JPA provider level) to make sure the method actually returns something.
