Calling Backing Bean Method with h:outputLink

Is there a way to call a backing bean using h:outputLink isntead of h:commandLink ?

No, you can't. You however can just let it point to a JSF page and make use of the constructor of the involved request scoped managed bean.

Hello,

the problem is.
1. before loading the page a javascript comes on which i clicked ok
2. the page gets loaded and the button is there which gets automatically clicked and the managed bean associated with prints a message on console using SOP.

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...

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 Backing Bean method from href tag in JSF. -- URGENT

Hi guys,
i am new to JSF. i want one option. how to call a backing bean method from href.

If anyone knows pls help me. Its Urgent. If u can, give me the code also.
Suggestions will be appreciated.
Thanks

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].

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 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.

Calling a backing bean method after load of fragment in adf

I needed to call a backing bean method after page load of fragment in adf.
I used the method suggested in:
https://community.oracle.com/message/11044570
only difference is im giving the if clause as:
if (refreshFlag == RegionBinding.RENDER_MODEL ) {
instead of
if (refreshFlag == RegionBinding.PREPARE_MODEL)
It was working fine, but page was not getting refreshed so used the code as mentioned in example:
public void refresh() {
          FacesContext facesContext = FacesContext.getCurrentInstance();
          String refreshpage = facesContext.getViewRoot().getViewId();
          ViewHandler viewHandler =facesContext.getApplication().getViewHandler();
          UIViewRoot viewroot = viewHandler.createView( facesContext, refreshpage);
          viewroot.setViewId(refreshpage);
          facesContext.setViewRoot(viewroot);
Now issue is once page is loaded and backing bean method is called, the refresh code refreshes the page and upon page load, refresh method is called again in recursive fashion.
please advise what to do in such scenario?
I tried to do selective refresh using some variable(also with static) but it does not help as page wont be refresh at all or page will keep refreshing recursively.

Use clientListener on the page load event
<af:document id=”d1″>
    <af:serverListener type=”onloadEvent”
                       method=”#{<managedbean name>.<method name>}”/>
    <af:clientListener method=”onLoadClient” type=”load”/>
    <af:resource type=”javascript”>
    function onLoadClient(event) {
      AdfCustomEvent.queue(event.getSource(),”onloadEvent”,{},false);
      return true;
    </af:resource>

How to call a AM method with parameters from Managed Bean?

Hi Everyone,
I have a situation where I need to call AM method (setDefaultSubInv) from Managed bean, under Value change Listner method. Here is what I am doing, I have added AM method on to the page bindings, then in bean calling this
Class[] paramTypes = { };
Object[] params = { } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
This works and able to call this method if there are no parameters. Say I have to pass a parameter to AM method setDefaultSubInv(String a), i tried calling this from the bean but throws an error
String aVal = "test";
Class[] paramTypes = {String.class };
Object[] params = {aVal } ;
invokeEL("#{bindings.setDefaultSubInv.execute}", paramTypes, params);
I am not sure this is the right way to call the method with parameters. Can anyone tell how to call a AM method with parameters from Manage bean
Thanks,
San.

Simply do the following
1- Make your Method in Client Interface.
2- Add it to Page Def.
3- Customize your Script Like the below one to Achieve your goal.
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("GetUserRoles");
operationBinding.getParamsMap().put("username", "oracle");
operationBinding.getParamsMap().put("role", "F1211");
operationBinding.getParamsMap().put("Connection", "JDBC");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
i hope it help you
thanks

How to call the backing bean method through javascript

I want to fire the event on command button and backing bean method should be invoked from javascript dynamically.
can anybody help me asap

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

Best practice for calling an AM method with parameters

Which will be the best way to call an AM method with parameters from a backing bean.
I usually use the BindingContainer to get the operation binding and then call execute function. But when the method have parameters, how to do it?
Thanks

Hi,
same:
operationBinding.getParamMap().put("argument1Name", argument1Value);
operationBinding.getParamMap().put("argument2Name", argument2Value);
operationBinding.execute();

About backing bean method's invokation

Hi,
I have a backing bean method binded to a component:
<af:selectOneChoice value="#{bindings.managerId.inputValue}"
label="Manager" valign="middle"
binding="#{backing_searchDocuments.managersList}"
valuePassThru="true" immediate="false"
rendered="#{bindings.ListManagersIterator.estimatedRowCount > 1}">
<f:selectItems value="#{bindings.managerId.items}"/>
When page refreshes component executes his binding method. But in some cases, actually when I press the commandMenuItem leading to the same page where I am it seems that it doesn't get invoked.. how can I manage the invocation of backing bean's methods? I need it invoked every time any request is made.. How to do that?

Mario,
this method is executed when the component re-draws. So anything other than a PPR request makes this binding method being called.
If PPR is used with your commandMenuItem, them make sure the PPR trigger is set to refresh the component.
I don't know what code it is that you need to execute each time, but maybe putting this on a action listener is a better idea
