You can make use of the constructor of the backing bean or the @PostConstruct annotation if you want to use managed properties.
You may get some ideas out of this: [http://balusc.blogspot.com/2006/06/communication-in-jsf.html].

How to call Backing bean method from JS

I want to call commandlink action from JS,
I'm trying document.getElementById('formPageInfo:btnCreateQuote').click() in javascript.
But it is not working any ideas around?
Code is for commandlink : <h:commandLink action="#{ManagedController.businessListActions.createNewQuote}" accesskey="C" title="Start Quote" id="btnCreateQuote"> <h:outputText value="Start Quote" /></h:commandLink>
Any help/Suggestions around?

I think that not exist a specific way to do it with jsf. Maybe you should ask in other forum more related with javascript, as a tip, if you can use jQuery in your environment, jQuery.trigger() can simulate a click on a button or command link. I have used it with a h:commnadLink and worked fine.

Hi,
this gonna be a hack, but here's how it could work
- you create a Servlet that accesses the FacesContext to obtain a managed bean
- you issue a XmlHttpRequest from the button to your servlet to obtain the payload
- show the retrieved values in your HTML
see http://www.thoughtsabout.net/blog/archives/000033.html for the middle part

Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component. I.e., I would like to take an action when a user clicks in a column in a datatable.

How to call backing bean method when user tabs out of af:inputListOfValues field

Hi,
I am using jdev 11.1.2.4.
I want to call a backing bean method based on the value selected in the af:inputListOfValues field.
The requirement is similar as Frank Nimphius-Oracle has demonstrated here https://blogs.oracle.com/jdevotnharvest/entry/how_to_notify_the_server but with Input List of Values component.
The fields I want to call method from is
<af:inputListOfValues id="appealNameId"
                      popupTitle="Search and Select: #{bindings.AppealName.hints.label}"
                      value="#{bindings.AppealName.inputValue}"
                      label="#{bindings.AppealName.hints.label}"
                      model="#{bindings.AppealName.listOfValuesModel}"
                      required="#{bindings.AppealName.hints.mandatory}"
                      columns="#{bindings.AppealName.hints.displayWidth}"
                      shortDesc="#{bindings.AppealName.hints.tooltip}"
                      binding="#{backingBeanScope.backing_Donation.appealNameId}"
                      autoSubmit="true" clientComponent="false">
                      <f:validator binding="#{bindings.AppealName.validator}"/>
                      <af:autoSuggestBehavior suggestedItems="#{backingBeanScope.backing_Donation.onSuggestAppeal}"/>
                      <af:clientListener method="onBlurTxtField" type="blur"/>
</af:inputListOfValues>
<af:serverListener type="onBlurNotifyServer"
                   method="#{backingBeanScope.backing_Donation.onBlurNotify}"/>
as you can see, af:serverListener is outside the af:inputListOfValues which probably is the reason its not executing this method?
public void onBlurNotify(ClientEvent clientEvent) {
   // get a hold of the input text component
   RichSelectOneChoice inputTxt = (RichSelectOneChoice) clientEvent.getComponent();
   //do some work on it here (e.g. manipulating its readOnly state)
   //Get access to the payload
   Map parameters = clientEvent.getParameters();
   System.out.println("SubmittedValue = "+parameters.get("submittedValue"));
   System.out.println("LocalValue = "+parameters.get("localValue"));
I've tried to put serverListener tag inside the <af:inputListOfValues> but getting below error
"Server Listener is not valid child of Input List of Values"
any ideas please?
thanks

As first, check to see that you are using correct type for af:serverListener (thet one you are queue in the javaScript onBlurTxtField function)
If still does not work, go to directly to the page source code, and put af:serverListener "by hand", as a child for af:inputListOfValues.
Because it is possible that these messages are false alarm...

Calling backing bean method from HttpSessionListener

Hi,
I am detecting session expiration through HttpSessionListener's sessionDestroyed() method. I have a logout() method in my backing bean which does all the session clean up. If the user clicks the logout link, then I call the logout method and do the clean up. But when the user closes the browser, then I believe that the HttpSessionListener's sessionDestroyed() method will be called. How do I call the logout() method of my backing bean from from sessionDestroyed() method of HttpSessionListener.

I did as you said, but the finalize method is never called. I can see the session timing out and sessionDestroyed() method being called, but not the finalize() method. Here is the code for sessionDestroyed()
    public void sessionDestroyed(HttpSessionEvent sessionEvent){
        System.out.println("Session Destroyed Called");
        HttpSession session = sessionEvent.getSession();
        session.invalidate();
        System.gc();
    }and for finalize()
    public void finalize() throws Throwable{
        System.out.println("In Finalize Method");
        FacesContext ctx = FacesContext.getCurrentInstance();
        Object requestObject = ctx.getApplication().getVariableResolver().
                               resolveVariable(ctx, "databaseCon");
        DatabaseCon databaseCon = (DatabaseCon) requestObject;
        Connection con = databaseCon.getConnection();
        String sql = "DELETE FROM TEMP WHERE EX_ID = ?";
        PreparedStatement pstmt = con.prepareStatement(sql);
        pstmt.setInt(1,this.getExId());
        pstmt.executeUpdate();
        super.finalize();
    }

How to call jpf controller method from javascript

Can any one help me how to call pageflow controller method from JavaScript.\
Thanks.

Accessing a particular pageflow method from Javascript is directly not possible unless we do some real funky coding in specifying document.myForm.action = xyz...Heres what I tried and it did not work as expected: I found another workaround that I will share with you.
1. In my jsp file when I click a button a call a JavaScript that calls the method that I want in pageflow like this: My method got invoked BUT when that method forwards the jsp, it lost the portal context. I saw my returned jsp only on the browser instead of seeing it inside the portlet on the page of a portal. I just see contents of jsp on full browser screen. I checked the url. This does make the sense. I do not see the url where I will have like test1.portal?_pageLabe=xxx&portlet details etc etc. So this bottom approach will notwork.
document.getElementById("batchForm").action = "/portlets/com/hid/iod/Batches/holdBatch"; // here if you give like test1.portal/pagelable value like complete url...it may work...but not suggested/recommended....
document.getElementById("batchForm").submit;
2. I achieved my requirement using a hidden variable inside my netui:form tag in the jsp. Say for example, I have 3 buttons and all of them should call their own action methods like create, update, delete on pageflow side. But I want these to be called through javascript say for example to do some validation. (I have diff usecase though). So I created a hidden field like ACTION_NAME. I have 3 javascript functions create(), update() etc. These javascripts are called onclick() for these buttons. In thse functions first I set unique value to this hiddent field appropriately. Then submit the form. Note that all 3 buttons now go to same common action in the JPF. The code is like this.
document.getElementById("ACTION_NAME").value = "UPDATE";
document.getElementById("batchForm").submit.
Inside the pageflow common method, I retriev this hidden field value and based on its value, I call one of the above 3 methods in pageflow. This works for me. There may be better solution.
3. Another usecase that I want to share and may be help others also. Most of the time very common usecase is, when we select a item in a drop bos or netui:select, we want to invoke the pageflow action. Say we have 2 dropdown boxes with States and Cities. Anytime States select box is changed, it should go back to server and get new list of Cities for that state. (We can get both states and cities and do all string tokenizer on jsp itself. But inreality as per business needs, we do have to go to server to get dynamic values. Here is the code snippet that I use and it works for all my select boxes onChange event.
This entire lines of code should do what we want.
<netui:anchor action="selectArticleChanged" formSubmit="true" tagId="selectPropertyAction"/>
<netui:select onChange="document.getElementById(lookupIdByTagId('selectPropertyAction',this )).onclick();" dataSource="pageFlow.selectedArticleId" >
<c:forEach items="${requestScope.ALL_ARTICLE}" var="eachArticle">
<%-- workshop:varType="com.hid.iod.forms.IoDProfileArticleRelForm" --%>
<netui:selectOption value="${eachArticle.articleIdAsString}">${eachArticle.articleItemName}</netui:selectOption>
</c:forEach>
</netui:select>
See if you can build along those above lines of code. Any other simpler approches are highly welcome.
Thanks

ADF Faces Declarative Component onLoad event call Backing Bean Method

Hello.
We are trying to implement a declarative component, that will be used as Flex Fields for our application, ie, the components will be created dynamically through a database configuration, and who is responsible for organizing and creating the components, is the declarative components, and its own backing bean.
The declarative component, will receive a List of custom components, and with this list it is possible to create the components dynamically. We want the components to be created as soon as the page is loaded. The developer could place this declarative component in any region of his page, and even in another tab if he wishes. The problem is, that we cannot register a load event in the declarative component, since it doesn't have a document Object, to call the declarative components backing bean method that is responsible for creating components.
How could we simulate the onLoad (of the declarative components) so that the backing bean method (responsible for creating component, and putting it in the view tree) could be called ?
I've tried with a RENDER_RESPONSE phaseListener, but the beforePhase has no objects in the tree, and the afterPhase has already rendered to the client.
Any ideas on how to achieve this ?
Thanks a lot.
Regards,
John

Hi Frank, thanks for the response.
I'm curious about the dynamic declarative component. Any place I could check it out ?
Back to my scenario. I'll try to be more clear to what we need!
We have to have dynamic creation of components, based on a database configuration. This will allow our customers to have custom flex fields, without the need of us developing custom pages for each customer.
One solution we are trying out, is the declarative component. Why ? Because the developer (when developing the page), knows that this specific page, is possible of customization by the client (custom flex fields). With this, the developer would choose where on his page the custom flex fields will be placed. Note that at this point (design time), no component (input, buttrons, etc) is created. The idea of the declarative component, is just so the Developer knows where he wants the custom fields placed in his page (a tab, below the form fields, in a another panel group, and so on). The declarative component, has only a container, PanelFormLayout, and no other component.
What we want, is a way of calling our managed bean (the managed bean of the declarative component, that now I did configure it in the adfc-config.xml file , thanks for the tip) method, that's responsible for creating the custom components. The declarative component, receives a list of all the custom fields that needs to be created, at design time, through an attribute. The developer is responsible for setting this list when he drags the declarative component on his page.
Now that I've put the declarative components managed bean in the adfc-config.xml file, the @PostConstruct is called correctly, but I still have a problem. At this moment (postContstruct call), my component PanelFormLayout (that is binded to the managed bean), is null. So I cannot add any component to the PanelFormLayout.
Am I way out of line here Frank ?
Really appreciate your comments.
Thanks a lot.

How to call a bean method through a javascript function

I dont discover any problems calling the bean method in this maner:
<%= helpdesk.data() %>
But, when I use a Button Onclick= to call the script function and which then is going call my bean method
an error on the page is reported!
I have include som code which gives you the idea of what Iam searching for. And is it possible to call
the bean method without doing from a new jsp page?
If you have any suggestions to why it doesnt work, please let me know.
I use Apache Tomcat 4.0
Best regards Micah.
<jsp:useBean id='helpdesk' scope='application'
class='helpdesk.testdb'/>
<html>
<head>
<script language="javascript">
function broadcast()
helpdesk.data();
</script>
</head>
<body>
<input type="button" value="Broadcast" onclick= broadcast()>
</body>
</html>

It's actually quite simple:
Beans run server-side
Javascript runs client-side
So you will never be able to run server-side-code thru the client...

How to call a bean method in the faces-config file?

Hi,
I would like in my menu to call the method of a bean (it initialize some properties before opening the page) instead of opening directly the page, by I can't find how to do that.
I tried :
<managed-property>
<property-name>viewId</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
And :
<managed-property>
<property-name>outcome</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
With no success...
Can someone help me?
Thank you and merry christmas !

Hi,
a managed property only gives you a anlde to a bean or property, it doesn't execute it. To execute a bean, you can use a custom JSF PhaseListener that calls a bean method. The reference to the bean is achieve through value binding
ValueBinding vb = FacesContect.getCurrentInstance().getApplication().createValueBinding("Name of Managed Bean);
TypeOfBean theBean =(TypeOfBean) vb.getValue(FacesContext.getCurrentInstance());
.... theBean.theMethod() ...

***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

How to call a set method from within a constructor

Hello,
I want to be able to call a set method from within a Scanner, to be used as the argument to pass to the Scanner (from a source file). Here's what i tried:
private void openFiles()
        input = new Scanner( setSource );
    and here is the set method:
public String setSource( String in )
        source = in;
        return source;
    }obviously there will be more code in this method but i'm trying to tackle one problem at a time. Thanks in advance..

The "String in" declaration says: "Nobody may ever invoke setSource() without specifying a certain String. The content of the String is known at run-time only."
In no place in your code you say the compiler: "I want the 'in' variable (actually, parameter) of method setSource() to contain the first arg which is passed to the application".
This is exactly the same mechanism allowing you to write "new Scanner" with something inside the two parentheses.
