I'm wondering if is it possible to change the value of an attribute
I tried this but it does not work:
<p:menuitem value="ADD" action="#{a.setA2("NewA2Value")}"/>
Assume that I have this #ManagedBean class:
#ManagedBean
public class A {
private String a1;
private String a2;
public A() {
}
public void setA1(String a1) {
this.a1 = a1;
}
public void setA2(String a2) {
this.a2 = a2;
}
public String getA1() {
return a1;
}
public String getA2() {
return a2;
}
}
You have some options here.
Method expression
f:setPropertyActionListener
f:atribute
f:param
Take a look to this: http://www.mkyong.com/jsf2/4-ways-to-pass-parameter-from-jsf-page-to-backing-bean/
Example with f:setPropertyActionListener
<p:menuitem value="ADD" action="#{a.myAction}">
<f:setPropertyActionListener target="#{a.a1}" value="myValue" />
<f:setPropertyActionListener target="#{a.a2}" value="myValue2" />
</p:menuitem>
Don't forget the h:form
And your action should looks like this.
public String myAction() {
//String value = this.a1;
//String value2 = this.a2;
//You have to return the viewId for the navigation, or null
}
or
public void myAction() {
//String value = this.a1;
//String value2 = this.a2;
}

I am using PrimeFaces DataTable with Radiobuttons inside a one wizard tab. Is possible to somehow set Radiobuttons like required?
User shouldn't go to the next wizard tab until he will choose one option in DataTable with Radiobuttons.
Or have you any ideas how to resolve this problem? Thanks for any replies!
JSP page
<p:tab id="test" title="Test">
<p:panel header="Term page">
<p:dataTable id="collection" value="#{register.dataList}" var="dl" rowKey="#{dl.c_id}" selection="#{register.selectedTerm}"">
<p:column selectionMode="single" style="width:2%" />
<p:column>
#{dl.c_id}
</p:column>
</p:dataTable>
</p:panel>
</p:tab>
You can check for data selection in flowListener of <p:wizard> tag that is triggered when next/previous buttons are clicked and conditionally add FacesMessage:
public String onFlowProcess(FlowEvent event) {
String current = event.getOldStep();
String next = event.getNewStep();
boolean proceed = true;
if(current.equals("first") && next.equals("second") && (selectedData == null)) {
//proceed only when data was selected and user is moving to the next step
FacesMessage facesMessage = new FacesMessage("You need to make a selection in a datatable to proceed!");
FacesContext.getCurrentInstance().addMessage("form:selection", facesMessage);
proceed = false;
}
return proceed ? next : current;
}
The full example is provided below.
The view:
<h:form id="form">
<p:wizard widgetVar="wiz" flowListener="#{q16439053Bean.onFlowProcess}">
<p:tab id="first" title="First">
<p:message for="selection"/>
<p:panel id="selection" header="Term page">
<p:dataTable id="collection" value="#{q16439053Bean.list}" var="data" rowKey="#{data.name}" selection="#{q16439053Bean.selectedData}">
<p:column selectionMode="single" style="width:2%" />
<p:column>
#{data.name}
</p:column>
</p:dataTable>
</p:panel>
</p:tab>

I filled my rightList of the PickList with Objects from a web service, but when i select some elements, i want to get these elements in myManagedBean, because i'll affect them to an Object.
JSF :

Converter :

public class CmpltsTitresConcerter implements Converter {

public Object getAsObject(FacesContext context, UIComponent component,
String value){
ComplementsDispoSortieDTO cmpltSelect = null;
cmpltSelect.setCdComplement(Long.parseLong(value));
return cmpltSelect;
}
public String getAsString(FacesContext arg0, UIComponent arg1, Object obj) {
return String.valueOf(((ComplementsDispoSortieDTO) obj).getCdComplement());
}
}
Any help is greatly apprectiated!
Roughtly you need 3 things :
Custom converter for your object (Object to String, String to Object)
Getter/Setter with the List of your Objects choices
Getter/Setter with the List of your Objects selected
Everything is perfectly described here : RichFaces Showcase - pickList
EDIT :
Adding this should fix your problem :
<rich:pickList ...>
<f:converter converterId="cmpltsTitresConcerter" />
</rich:pickList>
also the converter property in <f:selectItems /> is not valid : f:selectItems
EDIT :
You should modify your converter like that to remove converting exceptions :
#FacesConverter(value="cmpltsTitresConcerter")
public class CmpltsTitresConcerter implements Converter
{
public Object getAsObject(FacesContext context, UIComponent component, String value)
{
ComplementsDispoSortieDTO cmpltSelect = null;
if(value != null)
{
cmpltSelect = new ComplementsDispoSortieDTO();
cmpltSelect.setCdComplement(Long.parseLong(value));
}
return cmpltSelect;
}
public String getAsString(FacesContext arg0, UIComponent arg1, Object obj)
{
String result = null;
if(obj != null)
{
result = String.valueOf(((ComplementsDispoSortieDTO) obj).getCdComplement());
}
return result;
}
}
Your selected objects are bound to the value attribute which must have a getter and setter.
I've got a simple composite component which has to render a inputText. When a put the value and press commandButton the follow exception is throw:
java.lang.IllegalArgumentException: Cannot convert 1 of type class java.lang.String to class sample.entity.Product
When i use h:inputText instead d:myInputText it's work fine.
Is possible use a FacesConverter and attribute forClass for composite component? I do not like to use converter attribute or converterId of tag f:converter.
Anybody help me?

I use Mojarra 2.1.14, Glassfish 3.1 and CDI.
Best regards.
I was able to reproduce it in Mojarra 2.1.14. This is a bug in Mojarra. It works fine in MyFaces 2.1.9. I've reported it to Mojarra guys as issue 2568. In the meanwhile, there's not really another option than explicitly specifying a <f:converter for> in the client or moving to MyFaces (which has its own set of specific quirks/issues as well though).
Using jsf I want to edit a employee profile, when user will click on any particular datatable row,then
I am able to get all that deatils of selected patient in an
arraylist. Now I want to set all the attritbutes in arraylist to
page1.xhtml backingbean , so When user will select a particular row,
he will navigate to page1.xhtml where he will get all these fields in
the form set already by arraylist attributes.
I am trying in this way.
> page1.xhtml
<h:outputLabel value="Name" />
<p:inputText id="name1" value="#{employeeBB.emp.name}" >
</p:inputText>
<h:outputLabel value="age" />
<p:inputText id="ag" value="#{employeeBB.emp.age}" >
</p:inputText>
<h:outputLabel value="code" />
<p:inputText id="code1" value="#{employeeBB.emp.code}" >
</p:inputText>

for(int i=0;i<empList.size();i++){
String name=empList.get(i).getName();
String age=empList.get(i).getAge();
String code=empList.get(i).getCode();
Employee e=new Employee();
e.setName(name);
e.setAge(age);
e.setCode(code);
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e); // now according to my logic object e will set to emp object of Employee, and
// that means all these values name ,agem and code will be set to my page1.xhtml and I will be able to see it.
}
}
But I am unable to get pag1.xhtml with filled values.
Show me the way.
The reason for it not being shown is that you are setting values in a object which you are creating
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e);
JSF lifecycle doens't know about this object and everytime you are seeing blank.
In AddEmployeeBB add this
#ManagedProperty(value="employeeBB")
private EmployeeBB employeeBB = null; // create getter setter for this
then instead of this :
EmployeeBB obj1=new EmployeeBB();
obj1.setEmp(e);
Use this:
this.employeeBB.setEmp(e);
I am facing an issue with <s:hidden /> The value is not populated.
<s:hidden name="objectName.stringName" /> works.
<s:hidden name="stringName" /> doesn't. I have getters and setters and I tried in debug mode. The getter function is called.
I also tried <s:hidden name="stringName" value="%{stringName}"/> But it did not work.
Could someone please provide any solution to this behaviour ?
