I am developing small web app using JSF/PrimeFaces. I am able to call bean from web, however, I am unable to return web. This is what I have:
requestLeave.xhtml
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:p="http://primefaces.org/ui"
xmlns:f="http://java.sun.com/jsf/core">
<h:head>
<title>Request leave</title>
</h:head>
<h:body>
<script language="javascript">
var today = new Date();
document.write(today);
</script>
<h:form id="form" >
<h:panelGrid id= "grid" columns="2" cellpadding="5">
<f:facet name="header">
<p:messages id="msgs" />
</f:facet>
<h:outputLabel for="title" value="Leave Title:" style="font-weight:bold" />
<p:inputText value="#{requestLeave.titleLeave}" required="true" requiredMessage="title is required." />
<h:outputLabel for="type" value="Type:" style="font-weight:bold" />
<p:inputText value="#{requestLeave.typeLeave}" required="true" requiredMessage="type is required." />
<p:commandButton value="Submit" actionListener="#{requestLeave.buttonAction}" />
</h:panelGrid>
</h:form>
</h:body>
</html>
RequestLeave.java
import javax.faces.bean.ManagedBean;
#ManagedBean
public class RequestLeave {
private String titleLeave;
private String typeLeave;
public String getTitleLeave() {
return titleLeave;
}
public void setTitleLeave(String titleLeave) {
this.titleLeave = titleLeave;
}
public String getTypeLeave() {
return typeLeave;
}
public void setTypeLeave(String typeLeave) {
this.typeLeave = typeLeave;
}
public String buttonAction() {
System.out.println("leave title " + titleLeave);
System.out.println("leave type " + typeLeave);
return ("index.jsp");
}
}
With this, I cannot return to index.jsp. Can anyone help me? Thanks in advance.
Change the actionListener attribute to action:
<p:commandButton value="Submit" action="#{requestLeave.buttonAction}" />
More info:
Differences between action and actionListener?

hello i was testing out the example given on the official primefaces website an i noticed that my <p:commandButton> does not work well in that once i click it to update a value, it stays highlighted and cannot be clicked again to update the value again. Here is the xhtml file:
<?xml version="1.0" encoding="UTF-8"?>

<p:spinner id="ajaxSpinner" value="#{spinnerView.number5}">
<p:ajax update="ajaxSpinnerValue" process="#this" />
</p:spinner>
<h:outputText id="ajaxSpinnerValue" value="#{spinnerView.number5}" style="padding-left: 10px" />
</p:outputPanel>
</h:panelGrid>
<p:commandButton value="Submit" update="display" oncomplete="PF('dlg').show()" />
<p:dialog header="Values" widgetVar="dlg" showEffect="fold" hideEffect="fold">
<h:panelGrid id="display" columns="2" cellpadding="5">
<h:outputText value="Value 1: " />
<h:outputText value="#{spinnerView.number1}" />
<h:outputText value="Value 2: " />
<h:outputText value="#{spinnerView.number2}" />
<h:outputText value="Value 3: " />
<h:outputText value="#{spinnerView.number3}" />
<h:outputText value="Value 4: " />
<h:outputText value="#{spinnerView.number4}" />
<h:outputText value="Value 5: " />
<h:outputText value="#{spinnerView.number5}" />
</h:panelGrid>
</p:dialog>
</h:form>
</html>
And this is the managed bean:
package uk.soton.lostatnight;
import javax.faces.bean.ManagedBean;
#ManagedBean
public class SpinnerView {
private int number1;
private double number2;
private int number3;
private int number4;
private int number5;
public int getNumber1() {
return number1;
}
public void setNumber1(int number1) {
this.number1 = number1;
}
public double getNumber2() {
return number2;
}
public void setNumber2(double number2) {
this.number2 = number2;
}
public int getNumber3() {
return number3;
}
public void setNumber3(int number3) {
this.number3 = number3;
}
public int getNumber4() {
return number4;
}
public void setNumber4(int number4) {
this.number4 = number4;
}
public int getNumber5() {
return number5;
}
public void setNumber5(int number5) {
this.number5 = number5;
}
}
I find this weird so does anyone have any solutions to this problem or is it the cause of something else like the web or pom.xml files and if so how can i fix this?
This question already has answers here:
How to dynamically add JSF components
(3 answers)
Closed 7 years ago.
I am doing dynamic textbox for request name and the value but when I click the add button on my .xhtml file it is always on size of 1. I want to get the current size of the List then add another blank object.
HomepageBean.java
#ManagedBean
public class HomepageBean {
private String url;
private String portNumber;
private List<RequestParameter> requestParameterList = new ArrayList<>();
public List<RequestParameter> getRequestParameterList() {
return requestParameterList;
}
public void setRequestParameterList(List<RequestParameter> requestParameterList) {
this.requestParameterList = requestParameterList;
}
/**
* #return the url
*/
public String getUrl() {
return url;
}
/**
* #param url the url to set
*/
public void setUrl(String url) {
this.url = url;
}
/**
* #return the portNumber
*/
public String getPortNumber() {
return portNumber;
}
/**
* #param portNumber the portNumber to set
*/
public void setPortNumber(String portNumber) {
this.portNumber = portNumber;
}
public void addRequestParameter(List<RequestParameter> requestParameters){
System.out.println("size: " + requestParameterList.size());
RequestParameter requestParameter = new RequestParameter();
requestParameters.add(requestParameter);
System.out.println("size: " + requestParameterList.size());
this.setRequestParameterList(requestParameters);
}
public void removeRequestParameter(RequestParameter requestParameter){
requestParameterList.remove(requestParameter);
}
}
and this is my .xhtml file which iterates the value of List from the bean
index.xhtml

Well I think your size is always 1 because in your addRequestParameter method you add only one element. Clicking next time this button you create new request and new empty list is created. You have to store your older objects somewhere (e.g. database).
When I click on the button New <p:commandButton actionListener="#{ecritureCtrl.newLine}" value="New" update="dataTableSaisiePiece" oncomplete="addRowOnComplete()" ajax="true"/>, a new row is added to my dataTable on only the first click and the page is refreshed. Several cliques except the first were not refreshes the dataTable. So to see my newly added rows, I use the F5 key to refresh my page. Certainly my update="dataTableSaisiePiece" not work or only works rather the first click.
Here is my page home.xhtml :

I'm starting to use JSF with primefaces library over an Hibernate project. I've tried to use wizard component to manage a form but, when I click any of the buttons in the wizard, I get the following warning and the action listener is not invoked.
I think the problem is that, in the wizard there are some p:commandButton because when I use h:commandButton, everything works. Could someine explain in what way primefaces commandButton ih different from the standard one, and how could I face this problem? What's different in the rendering process?
Thanks for your help!
Here's the warning:

try {

public void setTraduttore(Traduttore traduttore) {
this.traduttore = traduttore;
}
public InfoTraduttore getInfo() {
return info;
}
public void setInfo(InfoTraduttore info) {
this.info = info;
}
}
For the declaration of the bean I've tried both with the annotation #Managed bean and the faces-config file.
Here's my definition:
<managed-bean>
<managed-bean-name>traduttoreBean</managed-bean-name>
<managed-bean-class>guiBeans.TraduttoreBean</managed-bean-class>
<managed-bean-scope>view</managed-bean-scope>
</managed-bean>
Answer provided by comment:
The problem was that Trinidad libraries were in conflict with
Primefaces. Solved removing Trinidad libraries.
I'm having a problem when I include dynamically a page with <ui:include>, the action and actionlistener associated with the <p:commandButton> component is not being invoked.
I've tried to remove the tag <h:form> from the included page but the problem persists.What can I do to solve this problem?
