I am having a strange issue with the Faces messages.
Sometimes, the <p:growl>, <p:messages> display correctly the notification after executing some method. But there are specific JSF pages where no notification is shown.
For example:
public String create() {
try {
getFacade().create(current);
JsfUtil.addSuccessMessage(ResourceBundle.getBundle("/Bundle").getString("NotaCreated"));
return prepareCreate();
} catch (Exception e) {
JsfUtil.addErrorMessage(e, ResourceBundle.getBundle("/Bundle").getString("PersistenceErrorOccured"));
return null;
}
}
The method is called in
<h:commandLink action="#{notaController.create}" value="#{bundle.CreateNotaSaveLink}"/>
And it does not show the notification. But for other entities as well as for other operations the messages are displayed correctly. This happens also in other functions, where I need feedback and it is not shown as expected.
I've been searching around and read this post and tried some of the suggested solutions, including setting the ajax=false attribute in commandButtons and commandLinks or using the scripts posted, but none of that worked for me, so I ask this question hoping that someone can help me.
Do I have to configure something to make it work correctly? I need this to get fixed by tomorrow and I don't know what else to do.
Update:
These are the JsfUtil methods:
public static void addSuccessMessage(String msg) {
FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
FacesContext.getCurrentInstance().addMessage("successInfo", facesMsg);
}
public static void addErrorMessage(Exception ex, String defaultMsg) {
String msg = ex.getLocalizedMessage();
if (msg != null && msg.length() > 0) {
addErrorMessage(msg);
} else {
addErrorMessage(defaultMsg);
}
}
This is the Create.xhtml

I had the same problem. The faces message wasn't rendering it was being lost. I tried this code and it worked.
FacesMessage facesMsg = new FacesMessage(FacesMessage.SEVERITY_INFO, msg, msg);
FacesContext context = FacesContext.getCurrentInstance();
context.getExternalContext().getFlash().setKeepMessages(true);
context.addMessage("successInfo", facesMsg);
I hope it works.

I'm using <ui:include> to load a data table (I'm using Primefaces). I want use <ui:param> in the listener into the tag <p:ajax>. I tested the code that is down, but not trigger the event onRowEdit or onRowCancel.
This is my page:
...
<ui:include src="../Componentes/tablaEditable.xhtml">
<ui:param name="columnas" value="#{tabla2FuentesHL7.dataTableColumns}" />
<ui:param name="bean" value="#{tabla2FuentesHL7.listTabla2FuenteDTO}" />
<ui:param name="aceptarEdicion" value="#{tabla2FuentesHL7.onRowEdit}" />
<ui:param name="cancelarEdicion" value="#{tabla2FuentesHL7.onRowCancel}" />
</ui:include>
...
My data table:
<ui:composition

xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:p="http://primefaces.org/ui">

</p:cellEditor>
</p:column>
</c:forEach>
<p:column style="width:32px">

</h:form>
My bean:
#ManagedBean(name = "tabla2FuentesHL7")

enter code herepublic class Tabla2FuentesHL7 {
private static final long serialVersionUID = 1L;
private List<DataTableColumn> dataTableColumns = new ArrayList<DataTableColumn>();

FacesMessage msg = new FacesMessage("Elemento modificado");

FacesContext.getCurrentInstance().addMessage(null, msg);
}
public void onCellEdit(CellEditEvent event) {
Object oldValue = event.getOldValue();
Object newValue = event.getNewValue();
if (newValue != null && !newValue.equals(oldValue)) {
FacesMessage msg = new FacesMessage(FacesMessage.SEVERITY_INFO, "Cell Changed", "Old: " + oldValue + ", New:" + newValue);
FacesContext.getCurrentInstance().addMessage(null, msg);
}
}
}
This is the error:
javax.el.PropertyNotFoundException: /Componentes/tablaEditable.xhtml #12,76 listener="#{cancelarEdicion}": /Modulos/hl7.xhtml #31,104 value="#{tabla2FuentesHL7.onRowCancel}": The class 'com.queres.xedoc.consola.componentes.Tabla2FuentesHL7' does not have the property 'onRowCancel'.
If I change this:
<p:ajax event="rowEdit" listener="#{aceptarEdicion}" />
<p:ajax event="rowEditCancel" listener="#{cancelarEdicion}" />
for this:
<p:ajax event="rowEdit" listener="#{tabla2FuentesHL7.onRowEdit}" />
<p:ajax event="rowEditCancel" listener="#{tabla2FuentesHL7.onRowCancel}" />
my code works fine, but I need a dynamic data table. Is there any way to pass a parameter to the listener?
Thanks!
The <ui:param> can only pass value expressions, not method expressions.
Better make use of the ability of EL to parameterize method names via brace [] notation. Then you can just declare the method names as plain vanilla String.
<ui:include src="../Componentes/tablaEditable.xhtml">
...
<ui:param name="beanEdicion" value="#{tabla2FuentesHL7}" />
<ui:param name="aceptarEdicion" value="onRowEdit" />
<ui:param name="cancelarEdicion" value="onRowCancel" />
</ui:include>
<p:ajax event="rowEdit" listener="#{beanEdicion[aceptarEdicion]()}" />
<p:ajax event="rowEditCancel" listener="#{beanEdicion[cancelarEdicion]()}" />
Update as per the comments, it appears to still not work in PrimeFaces 5.1 even though the related issue says that it's already fixed in 3.5. You'd basically need to reopen the issue.
In the meanwhile, you can workaround this with help of <o:methodParam> tag of JSF utility library OmniFaces. This basically converts a value expression to a method expression:
<ui:include src="../Componentes/tablaEditable.xhtml">
...
<ui:param name="aceptarEdicion" value="#{tabla2FuentesHL7.onRowEdit}" />
<ui:param name="cancelarEdicion" value="#{tabla2FuentesHL7.onRowCancel}" />
</ui:include>
<o:methodParam name="aceptarEdicionParam" value="#{aceptarEdicion}" />
<o:methodParam name="cancelarEdicionParam" value="#{cancelarEdicion}" />
...
<p:ajax event="rowEdit" listener="#{aceptarEdicionParam}" />
<p:ajax event="rowEditCancel" listener="#{cancelarEdicionParam}" />
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:

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}" />

I am using schedule component of Primefaces. I am filling it with values from database and when the user selects sth from the selectonemenu an ajax event is triggered (I tried to put just the related code, if there is sth missing pls remind me):
xhtml:
<h:outputText value="Scope :" />
<h:selectOneMenu id="scope" value="#{scheduleView.scope}">
<f:selectItems value="#{lookup.scopeCombo}"/>
<p:ajax process="scope" update="schedule, scheduleForm, scheduleFormPG" listener="#{scheduleView.changeScopeType()}"/>
</h:selectOneMenu>
<p:schedule id="schedule" value="#{scheduleView.model}" editable="true"/>
Backing bean:
#ManagedBean
#ViewScoped
public class ScheduleView implements Serializable {
#PostConstruct
public void init() {
System.out.println("Init ");
scopeChange();
}
public void scopeChange(String scope){
System.out.println("scopeChange ");
model.clear();
events = (List<Event>) commonServis.bringEverythingByCriteria(Event.class, "scope" , scope);
for(int i= 0; i<events.size();i++){
model.addEvent(new DefaultScheduleEvent(events.get(i).getAd(), events.get(i).getStartDate(),events.get(i).getEndDate()));
}
public void changeScopeType() {
System.out.println("changeScopeType ");
scopeChange (scope);
}
The output of the above code is:
Init
scopeChange
When the user changes the value in the selectonemenu:
changeScopeType
Init
scopeChange
It is supposed to go into init method just once. But after the changeScopeType function is triggered it gets into the init method and fills the schedule with unrelated data. I thought it might be related to #Postconstruct annotation but I couldn't find any related explanation. Can anyone understand the reason and offer a solution?

The problem was this line of code:

update was refreshing the whole page, instead it should've only update schedule. When I change it to:

the problem solved.
Thanks everyone for their effort.

here the same code on Pastebin but it's a bit messed up: http://pastebin.com/W0XGa0d2
and here is my back up bean:
......
public List<Domaines> initComb()
{
.....
}
public List<Domaines> init()
{
if(choixDirection==0)
{
domaines=domainesService.getAllDomaines();
}
else
{
Directions direction=directionsService.getDirections(choixDirection);
domaines=domainesService.getDirDomaines(direction);
}
return domaines;
}
public void save()
{
......
}
public void delete()
{
......
}
public void update()
{
......
}
////////////////////////////////////////////////////////// setters & getters \\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\
......
public void setCodeDirection(Integer codeDirection)
{
this.codeDirection=codeDirection;
}
public Integer getCodeDirection()
{
return codeDirection;
}
public void setNomDomaine(String nomDomaine)
{
this.nomDomaine=nomDomaine;
}
public String getNomDomaine()
{
return nomDomaine;
}
public void setNomDirecteur(String nomDirecteur)
{
this.nomDirecteur=nomDirecteur;
}
public String getNomDirecteur()
{
return nomDirecteur;
}
......
}
i posted long codes cause don't where the problem is coming from.
Your mistake is that you're doing business action in a getter method instead of an action method which is called only once. You should not do business actions in getters. JSF EL uses getters to access bean properties. EL does not cache them when they're ever called once. Getters should solely return bean properties (or at highest do some lazy loading or quick and non-intensive calculation, e.g. a simple sum like return foo + bar;), but definitely not access the database or something.
Move that job to the constructor or #PostConstruct method or any event method of the bean. In this particular case, you likely want to use #PostConstruct to preload the list with help of an #EJB and let the ajax action listener point to the same method as well. In a #ViewScoped bean, this way it's called only once during first request of the view and also called only once when you change the selection.
#PostConstruct
public void init() {
if (choixDirection == 0) {
domaines = domainesService.getAllDomaines();
} else {
Directions direction = directionsService.getDirections(choixDirection);
domaines = domainesService.getDirDomaines(direction);
}
}
public List<Domaines> getDomaines() {
return domaines;
}
and fix the view accordingly
<p:ajax process="topacteurs" listener="#{domaine.init}" update=":mainform:domainlist" />
...
<p:dataTable id="domainlist" var="e" value="#{domaine.domaines}">
