[SOLVED] .jspx call from Backing bean

Hi,
I have a Button and after button click buttonAction() action is called. Now there I want:
if(condition == true){
zzz.jspx show
else{
something...
Thanks
Dan

Hi,
If buttonAction() method return String (not ActionListener ) that represent outcome (navigation rule) in faces-config.xml (or adfc-config.xml) you simple return navigation outcome.
public String buttonAction() {
if(condition == true){
return "navigateToPage1";
else{
something...
}In faces-config.xml you can define "navigateToPage1" as outcome.

Clarification on application method calls from backing bean.

Hi Experts ,
In our application we are using two different ways to call application module methods from backing bean.
allication module method name : addRowValidUnitInfo
it has 2 parameters serialNumber,modelNumber
1.
BindingContainer bindings1 =
BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding serialModelDetails =
bindings1.getOperationBinding("addRowValidUnitInfo");
serialModelDetails.getParamsMap().put("serialNumber",
serialNumber.getValue().toString());
serialModelDetails.getParamsMap().put("modelNumber",
modelNumber.getValue().toString());
serialModelDetails.execute();
String result =serialModelDetails.getResult().toString();
2.
EWarrantyAdminModule appModule =(EWarrantyAdminModule)
Configuration.createRootApplicationModule(amDef,config);
try {
String result = appModule.addRowValidUnitInfo(serialNumber.getValue().toString(), modelNumber.getValue().toString());
} catch (Exception e) {
finally {
Configuration.releaseRootApplicationModule(appModule,true);
Can any one tell me which one gives best performance and which one should be used in which situations.
For me both are working fine but just want to know whcih is the best practice and which gives best performance.
Regards
Gayaz

The approach 1 is the right way.
Reasons:
1) With Approach 2 - you are creating new ApplicationModule on the fly and release it at the end of the request. If you are invoking multiple method calls, you need to the same for each & every call.
This is not reusing the existing application module.
2) If the use cases which does calls for maintaining state across requests from the same client - across the application flow, Approach 2 cannot be used.
Read this blog post from Jobinesh (which indirectly distinguishes both these approaches).

Calling function from Backing Bean or JSP page

We are on Jdeveloper 10.1.3.3.0, ADF Faces, JSF Faces .., Currently there is a function call from Javascript event (onmouseover) in the JSP page. I want to call this function from a backing bean or JSP page, as I have to pass some values to this function.
For Ex., I have a function call like return submit('A','B','Test'); on the Javascript event (onmouseover) in jsp page. I want to remove this function from the javascript event and call from backing bean or jsp page to pass some values into the submit() function. I appreciate if anyone can give some example of how to call this function from backing bean or jsp page in the <SCRIPT> or <SCRIPTLET>
Thanks,
Ram

A use case would be helpful so that we can get a better idea of what you want to do.
As a general rule, there is no way to call a client side Javascript function from a backing bean, which is server side. However, there are ways to inject information from a backing bean into your Javascript call. For instance, I have an application that uses Google Maps API. It has an onload call to a Javascript function that builds the map and designates it's center point. The center point comes from a backing bean as latitude and longitude properties. So here is my body tag:
<afh:body onload="initialize(#{backing_searchResults.latitude},#{backing_searchResults.longitude},#{searchCriteria.distance})"
onunload="GUnload()">onload calls the Javascript function called initialize, and passes the latitude, longitude, and distance from the bean. Is the function really being called from my backing bean? No - the parameters are hard coded into the onload event code when the page is rendered. Does it do the job? Sure it does.

Is it recommended to instantiate Model object from Backing Bean

Wondering what are the best practices in developing JSF,Spring, Hibernate application.
Appfuse/Equinox example instantiate Model Object i.e. POJO in the Backing bean. Here is the snippet
UserForm.java (Backing Bean)
public class UserForm {
public User user = new User();
public UserManager mgr;
// Getter & Setter methods for user & mgr
//Persistence
public String save() {
mgr.saveUser(getUser());
addMessage("user.saved", getUser().getFullName());
return "success";
I undertand the purpose of having UserManager defined in backing bean but wondering why do we need to have Model (i.e. User) defined in backing bean . Is this a best practice?
Is it recommended to populate model object with data in the backing bean and then call for business methods like mgr.saveUser(getUser());
Regards
Bansi

Here is some more info
UserForm is a JSF managed bean,
User is a hibernate mapped POJO, and
UserManager is manager class in Spring
I am wondering about perfomance issues i.e. making DB calls from backing bean getters or setters. DB calls can mean a performance hit, and JSF will call the getters and setters multiple times per page request (which means you'll be doing multiple DB calls).

Hi,
to call the bean, use the EL in Java and reference #{backingBeanScope.mapBean.initMap} as a method expression. If you try and access the bean directly then chances are that the instance is not available. Using EL from Java always guarantees this

How to call popup from backing bean

Hi,
I have an application under jdev 11.1.1.1.0
I am using the explorer template.
I have my popups in one page and from another page i need to call these popups.
I cannot use the <af:showPopupBehavior> because i am using the <af:setActionListener> in my command button.
So in the action attribute I called my backing bean
public String showDelBoxPopup() {
   FacesContext context = FacesContext.getCurrentInstance();
   ExtendedRenderKitService extRenderKitSrvc =
     Service.getRenderKitService(context,ExtendedRenderKitService.class);
   extRenderKitSrvc.addScript(context,"AdfPage.PAGE.findComponent('delBoxPopup').show()");
   return null;
}But i always receive a null error.
How can i call a popup in one page from another page using backing bean.
Thank you in advance.
Emile BITAR

Hi,
You can use <af:setActionListener> with <af:showPopupBehavior>, if you set triggerType="click" on the showPopupBehavior and contentDelivery="lazyUncached" on the popup to ensure the popup will be raised after setActionListener.
I also don't understand what you mean by calling the popup from another page (is that page included as a region?), but if you say it works then your other option could be to bind the popup to the backing bean and use popup.getClientId() in your javascript.
String script = "var popup = AdfPage.PAGE.findComponent(\"" + popup.getClientId(fc) + "\"); popup.show();";Pedja

Can we call a javascript function from backing bean class?

I have a requirement. In a multiselect table, when users selects some rows and clicks a button. Depending upon some condition, an alert box should appear with 2 buttons 'Yes' and 'No'. On clicking yes, certain field values in the selected rows of table should change. On clicking no, the alert box should close. As far as i know alert box can be done only in JS.
Please help me, if a javascript function can be called in backing bean method or suggest some way where alert boxes can appear through ADF.

I need to go back to the backing bean as i need to iterate through each selected row of the table in a method( method written for command button) and then if atleast one of the selected rows has job field='Manager', then an alert box needs to be displayed. If none of the rows have job field as 'manager', alert box should not be displayed.
If I write the function for onclick, i cannot iterate through the selected rows of the table in JS function.
Please suggest a way to do this.

Display values on new window from backing bean HashMap

Hi,
I need to open a new window when user clicks on some link from the current page. New window will display few values which are set once the link is clicked.
I have created a bounded task flow with a jspx page added into the task flow. This jspx page contains a jsff page. While clicking on the link, I have called backing bean method which will create and set a HashMap containing key-value set which is used to display on new window.
New window is created by javascript. And I am not able to get HashMap values which are set by bakingbean method.
Is there anyway to solve this?
Code:-
Backing Bean method to open new window
private void launchWindow () {
FacesContext facesContext = FacesContext.getCurrentInstance();
// Taskflow parameters map
Map <String, Object> params = new HashMap <String, Object> ();
// Get taskflow URL to be opened in new window.
String taskflowURL = ControllerContext.getInstance ().getTaskFlowURL (false, new TaskFlowId (
AppsConstants.DESCRIPTION_TASKFLOW_DOCUMENT,
AppsConstants.DESCRIPTION_TASKFLOW_ID), params);
taskflowURL = taskflowURL.replaceAll("%2F", "/");
ExtendedRenderKitService erks = Service.getRenderKitService (FacesContext.getCurrentInstance (), ExtendedRenderKitService.class);
String jsScriptWindowOpne = "window.open(\"" + taskflowURL + "\", \"" + resourceBundleMapper.getString (AppsConstants.LBL_NOTI_DESC_NEW_WINDOW_TITLE) + "\");";
try {
erks.addScript (FacesContext.getCurrentInstance(), jsScriptWindowOpne);
} catch (Exception e) {
logger.log (Level.SEVERE, "Exception while adding javascript to open a new window in ExtendedRenderKitService object. " + e);
New window jsff page
<af:outputText value="#{backingBeanScope.notification.notificationDescriptionMap}" />
Output
I want to get values from this HashMap, to test the size/content of this Map, I have printed this Map.

Hi,
Yes its possible..
A simple google search gave me this Result.
Betw:
you can also open taskflow as popup in your page(inline popup) instead of opening the taskflow in other browser window.

How to show popup from backing bean code immediately?

Hi,
I'm using JDeveloper 11.1.2.1.0 and have problems with showing popups. I have a button with an action on my page and a method in backing bean.
I want to rise up few popups from this method in backing bean (for example just an anouncement that something will happen) or a dialog
(for example a question if you want to continue).
I understand how to get a dialog response to deal with it in code, but the problem is that the popup doesn't show up immediately, but only when
this method called on button finishes. I'd like to handle dialog responses in the middle of the action and then the code to continue with the execution.
Here is my backing bean code:
private RichPopup popup;
public String test() {
//Some code...
RichPopup.PopupHints hints = new RichPopup.PopupHints();
popup.show(hints);
//Here is the place for code which I want to be executed after popup closes,
//but is executed before the popup shows...
return null;
And here is part of my jssf:
<af:commandButton text="Test" id="cb1"
action="#{popupBean.test}"/>
<af:popup id="popup" binding="#{popupBean.popup}">
<af:dialog id="dialog" type="yesNo"
title="Dialog"
dialogListener="#{popupBean.onDialogAction}"
binding="#{popupBean.dialog}" clientComponent="true">
<af:outputText value="Do you want to continue?" id="ot1"/>
<af:clientListener method="onDialogCancel" type="dialog"/>
<af:serverListener type="DialogCancelHandlerEvent" method="#{popupBean.onDialogCancel}"/>
</af:dialog>
</af:popup>
Can someone give me some answer how to show the popup from backing bean code immediately?
Thanks in advance,
Tina

If you want to execute code after popup closes, then put this code in PopupCanceledListener or in DialogListener(you can't block method execution).

Few basic doubts about accessing AM from backing bean class

Hi ADF experts,
I have just started working in ADF Faces.I made a sample search page.My page is attached to a managed backing bean. I have attached command button on my page to a custom method in backing bean class.
So on, click of button this method is called in backing bean.Now, i have few doubts:
1)How to get values of various UI beans in this event code?
2)I am accesing AM , in my method with this code:
FacesContext facesContext = FacesContext.getCurrentInstance();
ExternalContext extContext = facesContext.getExternalContext();
Application app = facesContext.getApplication();
DCBindingContainer binding = (DCBindingContainer)app.getVariableResolver().resolveVariable(facesContext, "bindings");
//Accessing AM
ApplicationModule am = binding.getDataControl().getApplicationModule();
iS this correct ?
3) After getting handle of am how to call my custom method in AM Class?there was "invokeMethod" API in application module class in OAF, is there any such method here?
Please help me.
--ADF learner.

Thanks for ur response Frank, actually I am from OA Framework back ground.It would be great if help us a little with ur valuble thoughts.
OA Framework also uses bc4j in model layer of framework. We have a requirement where our existing developers from OA Framework have to move to ADF to make a new application where time lines are quite strict.If this would not be possible we will switch to plain jsp and jdbc,but our tech experts say ADF Faces is the best tech.
In OA Framework, Application Module is key class for all busiess logic and Controller is used for page navigation. So, I m just trying to find the same similarity , where we write we add all event codes in custom action methods in the backing bean class of page, which we consider equivalent to process form request method in Controller class of OAF.
But there are two things, I still want to know:
1)While page render, how to call specific AM methods(like setting where clause of certain VOs)
2)In action methods, the way i described(I found that in one thread only)to access AM, what is wrong in that?Also, I went through
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
where coule of examples use similar approach to access AM from backing bean class and call custom methods of AM(Doing various, deletes etc from VOs).
3)In these methods can we set any property of beans on the page, I am asking because in OAF, generally we use PPR for js alternatives.But all properties of beans cannot be set in post event.
Thanks and Regards

Web services and ADF 11g- get Result from backing bean

I'm executing an action from backing bean (call Web service that returns complex data types)
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("unesiPonudu");
Object result = operationBinding.execute();
result is instance of oracle.adf.model.adapter.dataformat.XMLHandler$DataCollection but DataCollection is not accessible.
How to get results from method?
Tnx,
Andreja

Hi,
there should be a result iterator in the Executables section which cotnains the result. If not, create it from the WS result entry in the DC palette. Once this iterator gets updated, you get the data from this iterator as it would be the case of a table accesses the WS

Opening new browser window from backing bean

Is it possible to open new window from backing bean?
Regards, Simy

quite sure its not possibleIt is possible !! But a fifferent way of doint it!
I assume this is what you want ! on click of a button you want to go to the backing bean and come back with the new page on a new window !!
Do the following! On click of a button, call a javascript method which does the following
window.open('/jsf/somepage.jsf',.....)In the constructor of the backing bean, do the backend processing and set the fields of teh backing bean. And when the page gets rendered its as good as what you want...

How to reset RichSelectOneChoice in JSF form from backing bean method?

resetValue() is not working in this case. So any other method to reset from backing bean?

Did you store the component instance on a bean by selecting a “Binding” property of the “RichSelectOneChoice” component?
yourPage.jspx:
   <af:selectOneChoice
binding="#{myBean._selectOneChoice}">
</af:selectOneChoice>myBean.java:
    private RichSelectOneChoice _selectOneChoice;
    public void set_selectOneChoice(RichSelectOneChoice _selectOneChoice) {
        this._selectOneChoice = _selectOneChoice;
    public RichSelectOneChoice get_selectOneChoice() {
        return _selectOneChoice;
    private void rerenderSelectOneChoice() {
        AdfFacesContext.getCurrentInstance().addPartialTarget(this._selectOneChoice);
}

Set label of adf command button from backing bean

How can we set the label of a command button from a backing bean using EL?
Is it : <af: commandButton text="#{bindings.email.label}" action.....

hi,
create one string and generate accessor for it.
then in jspx, like this
text="#{PrintData.label}"
you can have the label in this way from backing bean.
private String label;
public void setLabel(String label)
this.label = label;
public String getLabel()
label = "test";
return label;
or else, through binding property of the command button, you can set it in the backing bean.
hope this is useful for you.
