I would like to have different messages on different message components, but unfortunately message always display on both message components.

public String callMsg001() {
FacesContext.getCurrentInstance().addMessage("msg001",
new FacesMessage(FacesMessage.SEVERITY_INFO, "This is msg001", null));
return null;
}
public String callMsg002() {
FacesContext.getCurrentInstance().addMessage("msg002",
new FacesMessage(FacesMessage.SEVERITY_INFO, "This is msg002", null));
return null;

Due to UI layout issue, I have to separate inputs into multiple form. How to submit JSF ajax with inputs from multiple forms?
Based on sample code below, how to get form1 input1 value when click on the Ajax Call button in form2?

I have a problem with CDI scope.
I have a bean with conversation scoped, ClientController, where I have client and phone object to be push in a service order. When I register a new client, I can push one or more phones to this client. For this, I have used conversation scope. However each request to push a new phone to my client is executing the #PostContruct method, doing the bean lose its state, even I am giving begin on the conversation when I push the first phone.
At first, I guess the problem was the bean configuration, but when I removed the template that was declared on the client page, the application works correct. This template use a bean with session scope, to control the page language by the user choice.
Next has my code, and you can follow my code on github repository by this link https://github.com/mcqueide/service-order.

I am pretty convinced that you are running into one of the following problems:
Conversation ends
try to play with some #PreDestroy methods to see when does the conversation vanish
make sure you do not end() conversations earlier (checking your code that would mean calling save/update)
New conversation is created every time you add phone (this is most likely the cause)
when you want another request to be associated with your running conversation, you need to make use of conversation ID (propagate it)
note that you can obtain the ID by calling conversation.getId()
to verify this, check that your URL contains the given conversation ID
also note that if you every time create a new Conversation, the old long-running ones are still hanging in there
Propagation of Conversation is done by appending a cid (conversation ID) to the request URL. Here is a quote from CDI spec (which I suggest you read) explaining when is conversation propagated automatically:
If the current Servlet request is a JSF request, and the conversation is in long-running state, it is propagated according to the following rules:
The long-running conversation context associated with a request that renders a JSF view is automatically propagated to any faces request (JSF form submission) that originates from that rendered page.
The long-running conversation context associated with a request that results in a JSF redirect (a redirect resulting from a navigation rule or JSF NavigationHandler) is automatically propagated to the resulting non-faces request, and to any other subsequent request to the same URL. This is accomplished via use of a request parameter named cid containing the unique identifier of the conversation.
I could resolved this with this:
<f:metadata>
<f:event listener="#{clientController.initConversation()}" type="preRenderView" />
</f:metadata>
Now when my page is render, I have my cid on my post action. But I don’t know if it is the better way to resolve this, because I want to transform my transaction in long-running just when the user click to add a phone, so if someone has a better idea, share please.
I'm trying to figure out how to open a dialog box when an element in a pie chart is clicked. I'm new to Primefaces, so most of what I've found in searches are more complex examples than what I'm trying to accomplish. The dialog box is opened using the Dialog Framework. I've been able to open the dialog via a command button no problem, so I'm pretty sure the problem isn't with the dialog itself.
Here's the initial page:

in my JSF2 app I have screens composed with :
Header
Body
In the header I have a combo list. At each change in value in the combo list I have an Ajax request that updates the data in the Body. So far everything is working properly. Now the home screen's structure should be change when the value of combo list change. To do this I have :
1 ManagedBean HomeBean that manage the home
1 ManagedBean HeaderBean that manage the header
2 object HomeScreen1.java and HomeScreen2.java that allows me to valued data from each screen
2 services HomeScreen1Loader.java and HomeScreen2Loader.java that manage loading of each type of screen
1 template home.xhtml
2 fichier home1.xhtml et home2.xhtml
When I log in to the application, I get the good page corresponding (Element type 1 => home page 1). But when I select a type 2 item, the actionListener methode is execute, ManagedBean's data was updated (for type 2 screen) , but the page does not updated. What do you do ?

I found the solution, the problem came to the ManagedBean ContextBean's templateHomeName attribute that was not properly valued. I added in loader.load(homeScreen1) and refresh and everything it's ok. I should upgrade my JSF version : 2.1.0-b11 to 2.1.26 because I had an error when refresh.
I am having trouble adding a p:remoteCommand to a form. It looks something like:

Here is the bean code:
package de.example.beans;
import java.io.Serializable;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.ViewScoped;
import javax.faces.event.ComponentSystemEvent;
import javax.faces.validator.ValidatorException;
import org.apache.log4j.Logger;
#ViewScoped
#ManagedBean
public class ResetBean implements Serializable
{
private static final long serialVersionUID = 7282752623428425109L;
private static final Logger log = Logger.getLogger(ResetBean.class);
protected String headline = null;
protected String message = null;
public ResetBean() {
log.error("ResetBean");
}
#PostConstruct
public void postConstruct() {
log.error("postConstruct");
}
#PreDestroy
public void preDestroy() {
log.error("preDestroy");
}
public void resetAction() {
log.error("resetAction");
headline = null;
message = null;
}
public void submitAction() {
log.error("submitAction headline="+headline+" message="+message);
}
public void validateForm(ComponentSystemEvent event) throws ValidatorException {
log.error("validateForm");
}
public String getHeadline() {
return headline;
}
public void setHeadline(String headline) {
this.headline = headline;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
Both the h:command button and the p:remoteCommand execute the same action in the same fashion. The difference is, that the h:command button responds to a mouse click, while the ESC key triggers the p:remoteCommand via javascript on using ESC key.
The problem is, that the route via p:remoteCommand seems to destroy the backing bean somehow (the bean is #ViewScoped). The #PreDestroy annotated method is never called, however: the next action on the page after using the p:remoteCommand forces the component to be created from scratch! Default constructor and #PostConstruct are called. Naturally some important parameters are missing now and the whole view gets shot to hell.
Any idea what is happening? Why the difference between p:remoteCommmand and h:commandButton in this instance? Any chance of working around the problem?
I could reproduce the problem. In my case and maybe the same case here (question provides only 'sample' code, not real one) it was caused by nested forms template->page.
If you have a ui:composition template or something similar to that, at the end of the generated HTML on client side it may creates nested forms like this:
<h:form>
...
<h:form>
...
</h:form>
...
</h:form>
which is invalid HTML code.
Remove unnecessary forms or reorganize code and test again. It should not call #postConstruct method when p:remoteCommand is called through JavaScript
