I am trying to create a page using richfaces, I created the following field
<h:inputText value="#{petTest.pet.name}"/>
faces-config:
<managed-bean>
<managed-bean-name>petTest</managed-bean-name>
<managed-bean-class>petstore.PetTest</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
managed bean:
package petstore;
public class PetTest {
private Pet pet;
public Pet getPet(){
return pet;
}
public void setPet(Pet pet){
this.pet = pet;
}
}
But I get a field and within it the literal value #{petTest.pet.name} instead of the value of the field. What am I doing wrong?
Is your h:inputText part of a h:form like this:
<h:form id="formId">
..
<h:inputText value="#{petTest.pet.name}"/>
..
</h:form>
Without a form h:inputText is not working.

I am new to primefaces and i have a problem to save my primefaces SelectManyCheckbox value to database. I am using hibernate and mysql. The sample code are give as below
My xhtml pages code is:
<h:outputText value="#{msg['elicense.examinationform.personal.classofcertificates']}"/>
<p:selectManyCheckbox id="grid" value="#{examinationFormBean.selectedClass}" layout="grid" columns="1">
<f:selectItems value="#{examinationFormBean.examinationPart}"var="className" itemLabel="#{className.name}" itemValue="#{className}" />
</p:selectManyCheckbox>
My bean is:
private String[] selectedClass;
private List<CertificateClass> examinationPart=new ArrayList<CertificateClass>();
getter()
setter()
The method where I want to save my checkbox is:
private void saveExaminationDetails()
{
examDetails.setElementaryPrinciples(); //bolean field
examDetails.setLightinig()
//no of setter
}
I am not able to find out how I will set the selected and not selected checkbox value on the method
Look at primefaces showcases: http://primefaces-rocks.appspot.com/ui/selectManyCheckbox.jsf
Selected values from examinationFormBean.examinationPart should setting in p:selectManyCheckbox attribute value and then you can used this selected list in bean method.
For your example should be something:
<p:selectManyCheckbox id="grid" value="#{examinationFormBean.selectedExaminationParts}" layout="grid" columns="1">
<f:selectItems value="#{examinationFormBean.examinationParts}" var="className" itemLabel="#{className.name}" itemValue="#{className}" />
</p:selectManyCheckbox>
And then you can use selectedExaminationParts in your saveExaminationDetails()
The p:selectManyCheckbox select values are biding a String Collection(List, ArrayList... etc) on managed bean. You just need to save each String existent on the Collection.
I will give you an example showing how you can do that:
Example:
...
#Named(value = "myBean")
#SessionScoped
public class InscricaoBean implements Serializable {
...
private List<String> selectedElemnts = new ArrayList();
//selectedElements get and set
...
On JSF you have something like:
...
<h:outputText value="#{msg['elicense.examinationform.personal.classofcertificates']}"/>
<p:selectManyCheckbox id="grid" value="#{examinationFormBean.selectedElemnts}"...>
<f:selectItems value="#{examinationFormBean.examinationPart}"var="className"
itemLabel="#{className.name}" itemValue="#{className}" />
</p:selectManyCheckbox>
...
On save method:
...
private void saveExaminationDetails()
{
for (String nameAux: selectedElemnts )
{
//you save the data here
}
}
...
Hello,
I'm putting ui:include inside h:panelGroup and rendering it dynamically when required.
The usual assumption and theory is, ManagedBean associated with the included page should not get initialized when ui:include is not rendered.
This is not happening when I use ui:repeat inside included page.
Here is a Example to repeat the Issue:
page.1.xhtml
<h:body>
<h:form>
<p:outputLabel value="#{mBeanOne.beanOnetxt}"/><br/>
</h:form>
<h:panelGroup rendered="false" layout="block">
<ui:include src="page2.xhtml"/>
</h:panelGroup>
</h:body>
MBeanOne.java
#ManagedBean
#ViewScoped
public class MBeanOne implements Serializable{
private String beanOnetxt;
public MBeanOne() {
System.out.println("MBeanOne - Constructor");
}
#PostConstruct
public void init(){
beanOnetxt = "This is Managed Bean 1";
System.out.println("MBeanOne - Postconstruct");
}
//SETTERS and GETTERS
}
page2.xhtml
<h:body>
<h:outputText value="#{mBeanTwo.beanTwotxt}"/><br/>
<ui:repeat var="var" value="#{mBeanTwo.versionList}">
<h:outputText value="#{var}"/><br/>
</ui:repeat>
</h:body>
MBeanTwo.java
#ManagedBean
#ViewScoped
public class MBeanTwo implements Serializable{
private String beanTwotxt;
private List<String> versionList;
public MBeanTwo() {
System.out.println("MBeanTwo - Constructor");
}
#PostConstruct
public void init(){
beanTwotxt = "This is Managed Bean 2";
versionList = new ArrayList<String>();
versionList.add("Playground");
versionList.add("Kestrel");
versionList.add("Merlin");
versionList.add("Tiger");
System.out.println("MBeanTwo - Postconstruct");
}
//SETTER and GETTER
}
As you can see in page1.xhtml I have use rendered="false" for h:paneGroup which encapsulates ui:include, but still MBeanTwo is getting initialized when I load page1.xhtml.
If I remove ui:repeat from page2.xhtml then MBeanTwo is not getting initialized.
Is this a bug in JSF, if so any workaround available?
Versions used and tested:
Primefaces 3.5
JSF 2.1.13 and 2.2.0-m05
The <ui:include /> piece is not relevant in your question, it could be everything done in the same view with identical behaviour.
Anyway, it seems that <ui:repeat /> tag doesn't check its parents rendered attributes before doing bean initialization. However, the mBeanTwo#getVersionList method never gets evaluated, just the managed bean is created. That could bring you to a slowdown if you perform data access when you construct your bean, but never should break your view. I'm able to reproduce the problem in Mojarra 2.1.x versions, however they have fixed it for 2.2.x latest minors.
Seems a Mojarra implementation bug rather than an expected behaviour.

I have two primefaces panel components in jsf page.I want to show some data on panels via clicking primefaces commandButton and show panel1 when page load.When clicking commandbutton,I do not want to show other panel.So I defined boolean variables in backing bean to use in visible property of panels.But it does not work.
Backing Bean:
#ManagedBean
#SessionScoped
public class Bean implements Serializable {
private boolean show;
#PostConstruct
public void init(){
this.show=true;
}
public void action_commandButton(){
this.show=false;
}
}
Jsf Page
<p:commandButton style="text-align: center;font-size:12px;"
action="#{bean.action_commandButton()}" value=""/>
<!--panel 1 -->
<p:panel visible="#{bean.show}">
<p:dataGrid>
<!-- data from datbase-->
</p:dataGrid>
</p:panel>
<!-- panel 2-->
<p:panel visible="#{!bean.show}">
<p:dataGrid>
<!-- data from datbase-->
</p:dataGrid>
</p:panel>
How to solve this problem?
Thanks in advance.
First, I show my code:
XHTML page:
<h:body>
<h:form id="ffffffffff">
<p:inputText value="#{prueba.dato}" >
<p:ajax event="keyup" process="#this" />
</p:inputText>
</h:form>
</h:body>
Bean:
#ManagedBean
#ViewScoped
public class Prueba implements Serializable {
private String dato = "ASSSS";
public String getDato() {
return dato;
}
public void setDato(String dato) {
this.dato = dato;
System.out.println("DAAAAAA: " + dato);
}
public void listener() {
System.out.println("LISTENEEEEEEEEEEEEEEEEEEEEEEEEEE");
}
}
Converter
#FacesConverter
public class SnaCarreraConverter extends SelectItemsConverter {
//CODE
}
My problem, setDato is always getting a null value. But when I modify the converter to this:
#FacesConverter(forClass=SnaCarrera.class)
adding forClass resolve my problem, I don't know why this happens. Is The inputText trying to find a Converter without add the converter property?
First of all, the SelectItemsConverter is for <f:selectItems>. The <p:inputText> is not a <f:selectItems>. So the SelectItemsConverter is useless for the <p:inputText>. See also its documentation and showcase.
Second, it's normal to give the Converter implementation an ID or a "for-class" in order to use it. Otherwise you can't refer it in the <x:inputSomething converter> attribute, or in the <f:converter> tag, or you can't auto-associate it with a certain class. This requirement is totally unrelated to the SelectItemsConverter. It's just required by standard JSF spec.
I created a simple master/detail using myfaces and richfaces. By clicking a h:commandLink in the rich:dataTable the user is able to open the detail view and edit the entity.
Now I want to create a URL that allows the user to open the detail view directly. Normally I would to this by creating an URL like /detail.jsp?id=12 - how can I achieve that with JSF?
You can construct the URL using parameters on a link control:
<h:outputLink value="reqscope.faces">
<f:param name="id" value="#{row.id}" />
<h:outputText value="link" />
</h:outputLink>
On the target page, you can read the id from the parameter map, either directly using the expression language or via a managed bean.
View:
<f:view>
id= <h:outputText value="#{param['id']}" />
<br />
id= <h:outputText value="#{lookupBean.id}" />
</f:view>
Bean:
public class LookupBean implements Serializable {
public String getId() {
FacesContext context = FacesContext.getCurrentInstance();
ExternalContext extContext = context.getExternalContext();
Map<String, String> params = extContext.getRequestParameterMap();
return params.get("id");
}
}
faces-config.xml declaration:
<managed-bean>
<managed-bean-name>lookupBean</managed-bean-name>
<managed-bean-class>reqscope.LookupBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
I use an a4j:commandlink to first pass the id of the entity I want to show details for to the detail view bean. And then I simply use document.location to navigate to the view.
<a4j:commandLink action="#{detailviewBean.setDetailID(entity.someid)}" value="#{entity.someid}" oncomplete="document.location='/app/detailview.seam'"/>
If you are using JSF 1.2, you can use f:setPropertyActionListener:
<h:commandLink action="#{reqscope.faces}">
<h:outputText value="link"/>
<f:setPropertyActionListener
value="#{id}"
target="#{lookupBean.id}"/>
</h:commandLink>
