Calling a bean method on select of Combo box item

Hi
On select of Combo box item in a form, text fields in the same form should be populated
dynamically.Is it possible to call a bean method which does this,by calling onSelect() method
of combo box ?
Thanks in advance,
Sridevi

Uff, sorry!
I ment that you write some code for the "onSelect" event which sends a request to the server with the selected value: onSelect="self.location.href='<%= request.getRequestURI()%>?selectedVal= ' + this.selectedIndex;"

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() ...

Use an ajaxical JSF framework, for example Ajax4jsf (part of RichFaces).
But why don´t you just use the constructor of the bean class to do some stuff prior to page loading?

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...

af:fileDownloadActionListener not calling the bean method

Hello,
I am using Jdev 11.1.1.6.
I have a page where user can generate the report and download it. I am using <af:fileDownloadActionListener> for this on my jsff (implemented as region using BTF).
The commandbutton with <af:fileDownloadActionListener> is calling a backing bean method. When user clicks the "Print" button, it is supposed to generate the report and allow user to download it.
The issue here is that the control never goes to bean method after button press. The browser keeps showing busy but no control passed to bean method. Interestingly, after you close the browser, it immediately goes to bean method.
I have tried waiting for long time (some times 15-20 min) but it never goes there during execution.
What could be going wrong here?
Code snippet from my jsff:
<af:commandButton id="cb1"
                  textAndAccessKey="Print"
                  partialSubmit="false"
                  clientComponent="true">
               <af:fileDownloadActionListener method="#{someMethod}"
                                              filename="#{someName}"/>
</af:commandButton>This is really frustrating as I have no clue what is going wrong here. The similar code works in other page but not here.
I would highly appreciate help here.
Thanks,
Jai

Like I said, it is working fine on my other pages and I tried on new page, just like yours, and it worked. It is not working where I need it.
I know the issue is somewhere with my page [child or parent, explained later] and I am looking for help on finding the root cause. Some direction/tip which I can follow and figure out the issue.
Other buttons are working fine on the page but <af:fileDownloadActionListener> does not work. The page seems to go in loop as it keeps printing generic messages that are generally printed when page is submitted.
This will continue until you close the page/browser and then the control goes to bean method.
Let me explain page structure:
My application is based on UIShell and is basically based one page application. Every page (jsff) is implemented as region using BTF. When user clicks on menu, MainPage is opened. This MainPage represents main structure using layout components like panelGroupLayout, panelTabbed, showDetailItem etc. These layout components contains <af:region> implemented using BTF.
The MainPage which has this issue is large page with almost 100+ BTF af:regions implemented under panelTabbed+showDetailItem combination.
<af:fileDownloadActionListener> has been implemented on one of the <af:region>, which is part of this MainPage.
Few Observations:
1. If I move this button [with <af:fileDownloadActionListener>] to any of the af:region under current MainPage then it does not work.
2. If I move this button [with <af:fileDownloadActionListener>] to any independent page or any <af:region> which is part of some other MainPage, then it works.
3. Other MainPage where it is working fine is also a fairly large page with almost 150+ BTF af:regions
4. All our MainPages are based on template, so there is very high level of consistency in behavior and other handlings.
For whatever reason, it is not working on my current page and I would highly appreciate any input based on above info [or otherwise] to find a root cause for this issue.
If I need to debug, where should I start? What could be causing that looping behavior, specially with <af:fileDownloadActionListener>.
Thanks,
Jai

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();
    }

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.
John

How to call Backing Bean method from href tag in JSF. -- URGENT

Hi guys,

You can make use of the constructor of the backing bean or the @PostConstruct annotation if you want to use managed properties.
