a4j:commandButton Back end bean method is not invoked on click event.

I am using below code. It seems back end bean method is not called when I click commandbutton. I think it has some thing to with rendering.

Every thing works perfectly. But when I click command button "#{testPropertyRefreshHelper.updatePropertyFileContentInRemoteServer}" backing bean method is not invoked. Other componenets are working properly.

try what the linked article says: make your bean session scoped.
NOTE: when working with Ajax I tend to make the backing bean session scoped to have less issues with partial updates and such. If you use JSF 2.0 you could make it view scoped to get the same result.

..this method should be invoked from the event-dispatching thread?

I see this (the title that is) in every single Java demo/example program on this (Sun's) site. However, I just tend to
public static void main(String[] args){
   new whateverTheClassIsCalled();
}And I've seen this approach on other sites and other example programs.
So what exactly is better about this;
    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
    }where createAndShowGUI() sets and packs the frame. I just do all this in the class constructor (when it's a JFrame!)
So what does all this thread dispatching stuff mean, why should I use it etc etc.
tia.

Is it just me? For some reason it rubs me the wrong way that swing isn't thread safe. From what I've read, my understanding is that its safe to modify swing components from other threads as long as they haven't asked to be painted. If you don't do paint(), pack() or setVisible(true) until the end of your initialization, you will be safe.
The reason for not being thread safe is almost certainly performance. Swing is slow enough as it is. Since the vast majority of Swing activity takes place in response to events and thus is on the EDT, there usually isn't a problem.
This is a serious nuisance in network and database programs where multiple threads are used. I end up using invokeLater a lot in those cases, but never for initialization. Sun has only started to recomment that recently.
Note that the fireXXX methods do not put the event on the EDT, these simply create Event objects and send them to Listeners. If they are executed off the EDT the Listeners will get called off the EDT.

Using more than one component to a back end bean

I have to ask,
if i use a component more than once on a page eg
                    <tr:panelGroupLayout>
                         <tr:selectOneChoice id="HPIDesc" label="HPI Description" value="#{iPISelectBean.selectValue}" >
                              <f:selectItems value="#{iPISelectBean.scenarioItemDescSelectItems}"/>
                              <f:attribute name="scenarioItemType" value="HPI"/>
                         </tr:selectOneChoice>
                         <tr:selectOneChoice id="UnEmploymentDesc" label="Unemployment Description" value="#{iPISelectBean.selectValue}">
                              <f:selectItems value="#{iPISelectBean.scenarioItemDescSelectItems}"/>
                              <f:attribute name="scenarioItemType" value="UNEMPLOYMENT"/>
                         </tr:selectOneChoice>
                         <tr:selectOneChoice id="ZeroDesc" label="Zero Description" value="#{iPISelectBean.selectValue}">
                              <f:selectItems value="#{iPISelectBean.scenarioItemDescSelectItems}"/>
                              <f:attribute name="scenarioItemType" value="ZERO"/>
                         </tr:selectOneChoice>
                    </tr:panelGroupLayout>     1. is that possible, or a good practice
2. can I get attribute values for the components in the backend bean.
Please help..!!

you need to do a join, there's no other way you can do it. What about using rownum to join the tables
select a.col1, b.col2, a.col1/b.col2 col3
from
(select col1,rownum r1
from table1) a,
(select col2,rownum r2
from table2) b
where a.r1 = b.r2
I think this would work. If you play with it more maybe you can even make it easier and more efficient

I am using a valueChangeListener attribute with <h:selectOneListbox>. As i am using onChange, the form is getting submitted but the associated backing bean method is not getting invoked.

       } This songInformation() method is not getting invoked.
Please help.

I never say to put every bean in session scope.
I recommend that the following beans are in session scope:
(1) the value property of h:dataTable
(2) the value property of f:selectItems
(3) the rendered property
They are evaluated before Update Model Values phase.

How to call the backing bean method through javascript

Hi
I have a command button associated with actionListener . Action Listener method associated with backing bean methods.
I want to fire the event on command button and backing bean method should be invoked from javascript dynamically.
can anybody help me asap

JSF<h:form id="formId">
<h:commandButton id="buttonId" value="submit" actionListener="#{myBean.action}" />
</h:form>JSdocument.getElementById('formId:buttonId').click();

***How to Invoke backing bean method by DOUBLE-CLICK the table ROW!!***

Hi,
How can I collect the selected row value & navigate to next page by DOUBLE-CLICK the result table row.
My application got searchResult page where I am displaying the list of user in result table. Then selecting any one row and navigating to master details page by clicking the continue button. Button Action method will collect the selected row userID which I am forwarding to the masterDetails page.
Same functionality I want to do by double click the row instead of clicking the button!!. I want to trigger the backing bean method if the user double click the row basically. Please help me in this how to do this?
Current button action method:
*public String userSelected() {*
FacesCtrlHierNodeBinding binding = (FacesCtrlHierNodeBinding) searchResultTable.getSelectedRowData();
currentRow = binding.getRow();
selectedNetID = (String) currentRow.getAttribute("netid");
System.out.println("selectedNetID -->"+selectedNetID);
requestContext.getPageFlowScope().put("netid",selectedNetID);
return "continue";
*}*

Puthanampatti ,
Yes, I am using the same. Below is my code. I am trying to get the object of the MAIN jspx page region (where I am displaying the fragments) and refresh the one. But cant able to get the object for the region it is returning null. without refresh seems the navigation wont work.
public void doDbClick(ClientEvent clientEvent) {
FacesCtrlHierNodeBinding binding = (FacesCtrlHierNodeBinding) searchResultTable.getSelectedRowData();
currentRow = binding.getRow();
selectedNetID = (String) currentRow.getAttribute("netid");
System.out.println("selectedNetID -->"+selectedNetID);
requestContext.getPageFlowScope().put("netid",selectedNetID);
try{
FacesContext facesCtx = FacesContext.getCurrentInstance();
NavigationHandler nh = facesCtx.getApplication().getNavigationHandler();
nh.handleNavigation(facesCtx, "", "continue");
System.out.println("region obj -->" +facesCtx.getViewRoot().findComponent("advse1"));
// Refresh the current region; advse1 is the id of the region component inside jspx page
AdfFacesContext.getCurrentInstance().addPartialTarget(facesCtx.getViewRoot().findComponent("advse1"));
catch(Exception e){
System.out.println("Error is: " +e);
Is this correct coding to get the region object?? actually the "result table" and "Master details" are 2 different fragments which are linked with task-flow and the task flow is part of main jspx page as a region. I am using that region ID to get the obj, but cant able to get so....!!! any idea

Action / actionListener in h:commandButton with managed beans

I have a problem with a backing bean whose method is not invoked when i click it. I've seen some posts on here about this yet, I still don't understand what I am doing wrong, if anything.
Some context...I've modeled my application after 'jcatalog' from this article:
http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html . It's simpler than the article -- I'm not using Spring/Hibernate and the persistence is the file system. For each business object (Resource), there's a backing bean (ResourceBean).
In short, I can't get the backing bean to respond to the button event for 'Add' bound to addAction. This is just like the jcatalog 'createProduct' impl -- which doesn't use the (FacesEvent fe ) approach.
Anyway, I would appreciate anyone's help to get past this.

Hey, anyway, have you note your jsp reference to the backing bean begins with a lowercase letter, and your backing bean class name begins with an uppercase letter?? I think that's it... I think, cause I'm too unexperienced in JSF.... Bye!!

Hi
there are following things you can do
1. log on to your SAP Router
2. check entries in SAPRoutab.
3. Telnet SAPSERV2 (Sap responding server) (Tcode oss1 will give you details of which SAP serve you are connecting ) on port 3299
4. if you are able to telnet SAPserve from your Router server then raise the call to SAP and ask whether they can reach your saprouter or not
5. check /etc/services files and check for service 3299 defined or not
6. telnet local Router server with port 3299
7 try to download Sap Note from SNOTE in you solman system.
all the best
Regards
Dishant.

Using bean methods within JSP declaration

Is it true that bean methods will not work in JSP Methods ?
For example:
// get the bean
<jsp:useBean id="FormValidate" scope="session" class="fsm.frontendCtr.FormValidate" />
// build a new method in jsp
<%!
boolean validate(HttpServletRequest req, String submitFlag) {
FormValidate.checkMandatory("ADRNACHNAME");
%>ServletExec return:
Undefined Variable or class name: FormValidate
If i use the bean Methods outside the method it worx.
Is there a trick with which I can use BeanMethods in a JSP Method?

ValueChangeListener not invoked inside h:dataTable h:inpuText

Hi,
I'm creating a simple dataTable with an inputText in each row. Each inputText has a valueChangeListener that is never invoked.
Does anyone know why this is happening ?
Thanks in advance,
- Juan

Thanks for your answer.
First option is excluded.
Third option also, because we are using RichFaces dataTable components.
You are saying that getter method for dataTable value attribute needs to return exactly the same object list which was returned in the request before when the list was populated for the first time, in order for commandButton in dataTable action method to be invoked, right?
In my case loading managed bean fields in constructor is excluded, because we are using EJB dependency injection, so our EJB's from which we are getting data aren't available in managed bean constructors. They are available in other methods. That leaves me to the field initialization in dataTable value getter method, when the list is populated for the first time. Which is the most elegant way to preserve this list between requests, and retrieve this list in later requests? Is saving object list in FacesContext session possible solution?

Closing the JWS Applet: shutdown hook is not invoked

Windows 2000, Java Web Start 1.4.2_05
I am running my applet with Java Web Start.
If I close the JWS Applet window by clicking the upper right "X" button, the applet is being shut down.
I want to perform a task like showing a warning message, before the applet disappears, but even if I implement the "Shutdown Hook", the according methods are not invoked by JWS.
Does anybody know, how I can prevent the JWS window from being closed without notifying my applet?

Another idea: Is it perhaps possible to disable/remove the "X" button from the JWS applet window?

Backing Bean method not invoked - h:selectOneRadio

Hi,
I am trying to invoke a method in the backing bean when a radio button is selected, but for some reasons the method is not getting invoked, any idea why is it so? copying the code for reference.
I have a command button in this jsp which when clicked is fetching the records(from the backing bean) perfectly and a radio button for each of the record so user can select any one of the records listed.

}Thanks in Advance

The valueChangeListener runs at the server side. You need to submit the form to the server side to invoke the valueChangeListener. There is no client side magic like Javascript.
To submit the parent form on change of the dropdown, just add the following attribute with a piece of Javascript to the h:selectOneMenu:onchange="this.form.submit()"

a4j:commandButton Back end bean method is not invoked on click event.
