I've the below command button and growl component:
<p:commandButton id="reservationAdd" actionListener=" {reservationBean.addReservation()}" value="Dodaj" oncomplete="PF('wdlgAddReservation').hide();" update=":frm" action="#{linkedTimelinesController.createTimeline()}">
<f:ajax execute="reservationAdd" onevent="click" listener="#{messageControler.eventAdded()}" render="dynamic"/>
</p:commandButton>
<p:growl id="msj" autoUpdate="true"/>
I'm adding a faces message as below:
#ManagedBean
public class MessageControler {
public void eventAdded(){
FacesContext.getCurrentInstance().addMessage(null,new FacesMessage(FacesMessage.SEVERITY_INFO,"Rezerwacja została dodana",null));
}
}
However, it does not show up in the growl component. How is this caused and how can I solve it?
My following minimal example works, perhaps you check the attributes of your commandButton

I have a simple example in which a JSF bean with view scope is called from different browser tabs
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

itemValue="#{item}" />
<p:commandButton value="submit" update="selectedValue" />
<p:outputLabel id="selectedValue" value="Selected item: #{testBean.item}" />
</p:panelGrid>
</h:form>
</h:body>
</html>

When I open the same page in a different browser tab, after selecting a value, I see the selected value from the other tab. I thought a view scoped bean would be created for each browser tab.
I am using Spring Boot v2.5.6, Glassfisch Jakarta Faces v2.3.17 and PrimeFaces v11.0.0
What I am doing wrong?
If I pass an expression to a composite component like
<My:myButton action="#{bean.myaction()" value="#{bean.buttText()}"
and try to use it in
<cc:implementation>
<h:commandButton actionListener="#{cc.attrs.action} value="#{cc.attrs.value}...
I get the exception "Target Unreachable, identifier 'bean' resolved to null".
But only if bean is a <ui:param name="bean" value="#{myRealBean}"/> inside a template. The error only occours with actionListener. The button text, resolved from the same bean in the same way will be shown.
This old question seems to have the same problem but no answer.
If I split the parameter to
<My:myButton bean="#{bean}" method="myaction" value="#{bean.buttText()}"
and use
<cc:implementation>
<h:commandButton actionListener="#{cc.attrs.bean[cc.attrs.method]()} ...
no error occours and everything works fine.
How can I use a function-expression in an actionListener inside a composite component, where the bean is a <ui:param?
Glassfish 4.1.1, Mojarra 2.2.12
And now, the MCVE
a bean:
package beans;
import java.io.Serializable;
import javax.faces.view.ViewScoped;
import javax.inject.Named;
#Named
#ViewScoped
public class Testbean implements Serializable {
public String getButtText() { return "Submit"; }
public void doAction() { System.out.println("Ajax was here."); }
}
a page
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:ui="http://xmlns.jcp.org/jsf/facelets" xmlns:h="http://xmlns.jcp.org/jsf/html"

<h:body>
<h:form id="testform">

</ui:include>
<ST:testButt text="#{testbean.buttText}" action="#{testbean.doAction()}"/>
<h:commandButton value="#{testbean.buttText}" actionListener="#{testbean.doAction()}"/>
</h:panelGrid>
</h:form>
</h:body>
</html>
and a template
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<ui:composition xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:ST="http://java.sun.com/jsf/composite/softeam">
<ST:testButt text="#{bean.buttText}" action="#{bean.doAction()}"/>
<h:commandButton value="#{bean.buttText}" action="#{bean.doAction()}" />
</ui:composition>
and the component
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:S="http://xmlns.jcp.org/jsf/composite" >
<S:interface>
<S:attribute name="action" method-signature="void action()"/>
<S:attribute name="text" type="java.lang.String"/>
</S:interface>
<S:implementation>
<h:commandButton style="display:inline-block"
value="#{cc.attrs.text}"
actionListener="#{cc.attrs.action}"
/>
</S:implementation>
</html>
All buttons will be shown (with the bean.buttText()) but only the second, third and fourth will call the action. The first button throws an exception when clicked.
Edit: Example reduced to JSF, no PrimeFaces components.
I need to get title of currently active tab inside my TabView. TabView is constructed with dynamic number of tabs with listener attached to "tabChanged":
<p:tabView value="#{bean.list}" var="listItem">
<p:ajax event="tabChange" listener="#{listenerBean.onChange}" />
<p:tab title="#{listItem.stringProperty}">
</p:tab>
</p:tabView>
The problem is that TabChangeEvent object received by onChange(TabChangeEvent event) always contains first tab instead of the active one.
public void onChange(TabChangeEvent event) {
event.getTab().getTitle(); //allways returns title of first tab
}
This behavior is only true for dynamic number of tabs in TabView if I define each tab explicitly, TabChangeEvent works fine.
Any suggestions? Thanks.
I use PrimeFaces 3.5 with JSF2.1 and Servlets 2.5
The following minimal example worked for my like a charm by printing the title of the tab to activate every time I click on it:

}
}
What should be the return type for getResponse and submit, and are both necessary?
When a guess is entered in either the firstForm or SecondForm, how do I echo that guess to the same webpage?
Either with ajax, and so not reloading the same page
or
loading a new page, guessResults.xhtml, for example, which echo's the guess.

I'm running facelets on Glassfish, using CDI, so am using #Named and not #ManagedBean -- some of the documentation above is more geared for #ManagedBean, but I'm not sure how much that matters.
The goal is one step better than "hello world", "hello world, your guess is " would be a good result. If there's a specific manual, I don't mind a RTFM to that specific documentation. The Oracle docs are probably the best for facelets?

outputs the submitted value to the response, along with the bird. It might make more sense to output the result to the same page, but this is sufficient.
i am trying to show a globalMessage in the main form as well as within a dialog. The message within the dialog only shows when the dialog is opened a second time.
I can't get it to work. Can anyone solve this problem? I'd really appreciate it!
