I'm using PrimeFaces 4.0 and Netbeans 6.9.1. I followed primefaces demo here:
DataTable Single Selection
Everything working fine expect button view. Here is my code:
Customer_list.xhtml
<p:growl id="msgs" showDetail="true" />
<h:form id="formTable">
<p:dataTable styleClass="table" id="customers" var="customer" value="#{customerBean.customer}">
<p:column>
<f:facet name="header">First Name</f:facet>
#{customer.firstName}
</p:column>
<p:column>
<f:facet name="header">Last Name</f:facet>
#{customer.lastName}
</p:column>
<p:column>
<f:facet name="header">Email</f:facet>
#{customer.email}
</p:column>
<p:column>
<f:facet name="header">DOB</f:facet>
#{customer.dob}
</p:column>
<p:column style="width:4%">
<p:commandButton id="selectButton" update=":formCreate" oncomplete="dialogCustomerCreate.show()" icon="ui-icon-search" title="Update">
<f:setPropertyActionListener value="#{customer}" target="#{customerBean.selectedCustomer}" />
</p:commandButton>
</p:column>
</p:dataTable>
</h:form>
<h:form id="formCreate">
<p:dialog header="Create New Customer" widgetVar="dialogCustomerCreate" resizable="false" id="dlgCustomerCreate"
showEffect="fade" hideEffect="explode" modal="true">
<h:panelGrid id="display" columns="2" cellpadding="4" style="margin:0 auto;">
<h:outputText value="First Name:" />

<h:outputText value="DOB:" />
<h:outputText value="#{customerBean.selectedCustomer.dob}" style="font-weight:bold"/>
</h:panelGrid>
</p:dialog>
</h:form>
customerBean.java
public class customerBean {
private List<Customer> customer;
private Customer selectedCustomer;
/** Creates a new instance of customerBean */
public customerBean() {
customer = new ArrayList<Customer>();
}
public List<Customer> getCustomer() {
CustomersDao cust_dao = new CustomersDao();
customer = cust_dao.findAll();
return customer;
}
public Customer getSelectedCustomer() {
return selectedCustomer;
}
public void setSelectedCustomer(Customer selectedCustomer) {
this.selectedCustomer = selectedCustomer;
}
}
CustomersDao.java
public class CustomersDao {
public List<Customer> findAll(){
List<Customer> list_cust = null;
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
String sql = "FROM Customer";
try{
session.beginTransaction();
list_cust = session.createQuery(sql).list();
session.beginTransaction().commit();
}catch(Exception e){
session.beginTransaction().rollback();
}
return list_cust;
}
}
Hope anyone suggest me what wrong in my code. It takes me 2 days to solve it. Thanks for reading!
You need to have a converter for your Customer class:
#FacesConverter(forClass = Customer.class)
public class CustomerConverter implements Converter {
#Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
if (value != null && !value.equals("") && !value.equals("0")) {
//find and return object from DAO
} else {
return null;
}
}
#Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
//return object id as string
}
}
1) Try removing your <h:form/>, since you're not submitting any information in that dialog;
2) Try to change your <p:commandButton update=""/> to update=":display";
3) Add process="#form" to your <p:commandButton/>;
4) If that works, i don't think you need that <h:form/>.
you did not mention the correct id for displaying popup dialog at commandButton attribute update.
<p:commandButton id="selectButton" update=":formCreate:display" oncomplete="dialogCustomerCreate.show()" icon="ui-icon-search" title="Update">
<f:setPropertyActionListener value="#{customer}" target="#{customerBean.selectedCustomer}" />
</p:commandButton>

in my xhtml i define a inputText variable from which i want to set a specific value to a specific field in my List. Every time i click confirm and debug my code the value is returned as "" (that i set in my init function). I have also tried hardcoding my inputText value to be set to dashboardFilterDialogBean.dashboardObject.texts[0] as in the only item in the list i define but still no result. I get 0 exceptions in my console
Xhtml
<p:dialog id="dashboardFilterDialog">
<h:form id="dashboard_filter_dialog_form">
<ui:repeat value="#{dashboardFilterDialogBean.dashboardObject.texts}" varStatus="loop">
<p:row>
<p:column>
<h:outputText value="Text" />
</p:column>
<p:column>
<p:inputText value="#{dashboardFilterDialogBean.dashboardObject.texts[loop.index]}" />
</p:column>
</p:row>
</ui:repeat>
</h:form>
<f:facet name="footer">
<h:form id="submit_dashboards_dialog_form">
<p:commandButton id="confirm_button" actionListener="#{dashboardFilterDialogBean.confirm()}" />
</h:form>
</f:facet>
</p:dialog>
Bean
public class DashboardFilterDialogBean {
private DashboardObject dashboardObject;
#PostConstruct
public void init() {
dashboardObject.getTexts().add("");
}
public void confirm() {
for (String txtValue : getDashboardObject().getTexts()) {
if (!txtValue.equals("")) {
...;
}
}
}
public DashboardObject getDashboardObject() {
return dashboardObject;
}
public void setDashboardObject(DashboardObject dashboardObject) {
this.dashboardObject = dashboardObject;
}
}
Object
public class DashboardObject {
private List<String> texts;
public DashboardObject() {
texts = new ArrayList<String>();
}
public List<String> getTexts() {
return texts;
}
public void setTexts(List<String> texts) {
this.texts = texts;
}
}
I've fixed my issue by adding <p:ajax event="blur" process="#this" /> into my inputText so it saves the value before i click confirm. So the end code looks like this:
<p:inputText value="#{dashboardFilterDialogBean.dashboardObject.texts[loop.index]}" />
<p:ajax event="blur" process="#this" />
</p:inputText>
This question already has an answer here:
How and when should I load the model from database for JSF dataTable
(1 answer)
Closed 1 year ago.
I have a bean that brings the list of products from the database, I can change it in onRowEdit normally, but when I do a search for the part method in the beanProd.searchProd () form it populates the datatable with related products and when I change some of them event.getObject () takes the object with an incorrect id and update incorrect product. Please HELP-ME

sorry for lack of details, it's my first post here, let's go to the details examples
all produtcts in datatable
Here are the products from the database that populate the datatable init () method with #PostConstruct annotation
When I search the form on the left with the word CREME he calls the searchProd method q populates a datatable with products that contain the word CREME
search form populate datatable search string
as you can see the datatable populated only with products containing the word CREAM
before the search I can change the product directly in the datatable normally it changes the product correctly in the database but when I do the search for a product that contains a certain word and I try to change it in the datatable it changes the product with the wrong id see before:
before
after
as you can see he should change the product with id 14 and he changes the product with id 12
wrong product changed
So, what do you think is the problem here?
Is there any way to make the change in the row along with some search filter?
I'm using JSF 2.2 and Primefaces 8.0
Sorry for my bad english.
This may happen if one of your methods updates the products list, but doesn't update the form (the view).
Start your app in the debug mode, and put a breakpoint on the setter of #{beanProd.produtos}, and find when your list is updated.
Good afternoon people! I'm trying to do an update through the datatable edit the Primefaces, but does not send the value of inputText upgraded to the bean. The process occurs almost correctly, the value is sent and updated, but the old value already loaded into datatable.
can anyone help me on this :)
Forgive my English. I do not speak or write very well ....

I think you should use other type of event, because rowEditInit is executing when you click pencil icon, and after edition when you click save icon is executing event rowEdit. Therefore try:
<p:ajax event="rowEdit" listener="#{pBean.onRowEdit}" update=":form:msgs"/>
Also forgive my English :)
Staff managed to solve. in fact the problem was in my listaprodutos get ... after entering an if and else, testing whether the product list was null, functioned normally.
The cool thing is, as a friend pointed out, always check the values passed by the network browser.

A few things: In general the action atributte is used for navigation (redirect to another page for instance). Also is better to use oncomplete beacuse it gets executed when your ajax request is completed, instead of onclick that fires the action (open the dialog in your case) in the moment when you press the button, skipping validation and such things.
If your problem was, refreshing the dialog content, with the update/process (ajax) mechanism, will be updated with your current selection if you do like the second snippet.
Does anyone know how do I show streamming tweet in .jsf page. I want to show user status directly when it comes on my page. I created backing bean named Tweet:
#Named(value = "tweet")
#Dependent
public class Tweet {
private String user;
private String status;
private String date;
And then set data when it comes in TweetBean:
#Named(value = "tweetBean")
#Dependent
public class TweetBean {
...
public void open() {
StatusListener listener = new StatusListener() {
#Override
public void onStatus(Status status) {
Tweet tweet = new Tweet();
tweet.setUser("#" + status.getUser().getName());
tweet.setStatust(status.getText());
tweet.setDate(String.valueOf(created.format(status.getCreatedAt())));
}
I am having facelet named tweets.xhtml but newly streamed tweets won't show. why? Should I use f:ajax render = "#form" or something else?
<h:body>
<h:form >
<div>
User: #{tweet.user}<br/>
Status: #{tweet.status} <br/>
Date: #{tweet.date} <br/>
</div>
</h:form>
</h:body>
I have found the solution using PrimeFaces p:poll component like so:
<h:form id="form">
<p:dataTable id="statuses"
value="#{tweetBean.statusesLinkedList}"
var="st"
sortMode="multiple"
rows="5"
paginator="true" >
<p:column headerText="Message:">
<h:outputText value="#{st.status}"/>
</p:column>
<p:column headerText="Date:" sortBy="#{st.date}">
<h:outputText value="#{st.date}"/>
</p:column>
<p:column headerText="User:">
<h:outputText value="#{st.user}"/>
</p:column>
</p:dataTable>
<p:commandButton type="submit" value="Stop"
actionListener="#{tweetBean.close()}"
ajax="false" action="index?facesredirect=true">
</p:commandButton>
<p:poll interval="3" update="statuses" />
