Get component Id in managed bean

Hi experts,
I am going to ask a foolish question, but since i'm a newbie i hope you'll forgive me .
I am using JDev version: 11.1.2.3.0. My question is: Is it possible to get a component id inside a managed bean? By components i mean, buttons or menu items. The scenario i would like to create is this:
I am using JasperReports to generate some required reports. I would like to do something like having a Menu with different items. By clicking each one of them, set a string in the managed bean i'm using to generate the reports (actually the string would be the name of the jrxml file i am going to load). And this string would get it's value based on which menu item is selected.
Is it possible to do such a thing? Or may be some other way would be more suitable?
Thank you in advance!

MenuRenderer is a class that renders the current value of
UISelectOne or UISelectMany component as a list of
menu options and makes use of getId.

Re:How to get the vo from managed bean

Hi all,

Thanks,

So you're not using ADF BC at all, right ?
From JSF point of view, it does not matter how you provide UI control values.
What you can do, for example, is to use pure JDBC in order to get and display the database values.
What you need in your backing bean, is appropriate properties (setter/getter method pairs).
In the getter, you can obtain DB values by using JDBC

Changing row selection of a af:table component in a managed bean

Hi,
how can ich programmatically change the selected row of a <af:table> component within a managed bean class?
I have a table which depends on the date settings of a <dvt:timeSelector> of a <dvt:lineGraph> component. Now when the timeSelector is moved to new dates the table should be refreshed by executing the query for the table again with the new dates. The problem is when the query of the table's view object is executed again the first row will be automatically selected after executing.
Now I want to achieve that the last row I have selected will be selected again after moving the time selector.
I searched already in the OTN Discussion Forum but didn't find a fitting solution.
Thanks in advance!

The problem is that executing the query moves the current roe to the first one.
What you can do is to save the current row (its pk), execute the query and then set the current row to the pk of the saved selected one. Set the table attribute displayRow="selected" and set the selected row of the table to the now current row.
One problem is that you have to be sure the last selected row is still in the record set of the new query result.
Here are some pointers with code:

Is there any method to get page name in managed bean? jsf2.0

Please help. Want to get page name in managed bean (application scoped). Page invoke bean through actionListener method.
Thanks in advance.

So, two solutions:
FacesContext.getCurrentInstance().getViewRoot().getViewId() - actual page
FacesContext.getCurrentInstance().getExternalContext().getRequestHeaderMap().get("referer") - url in browser

Why a getter method of a managed bean WILL be called multiple times

Why a getter method of a managed bean WILL be called multiple times during the JSF lifecycle?Why this designed?

This is by design indeed. Each step in the JSF lifecycle can call a getter to get the required information.

How to get ADF UI Component value in managed bean

JDev version 11.1.1.1.3.0
I have written a managed bean method and calling that method on valueChangeEvent of a Select boolean Checkbox ADF Component.
I want to retreive the value of some other component located in the same page as the checkbox. I need the value of the component into the manged bean. I know how to get the value of the checkbox eg:
public void selectCheckBoxListener(ValueChangeEvent evt){
boolean selectedValue = (Boolean)evt.getNewValue();
String oldvalue = (String)evt.getOldValue();
How can I access the value of an input text component in the above managed bean ? Can someone help on this?

Hi Sackam,
String selectedRowId = (String)(evt.getComponent().findComponent("rowId")).getAttributes().get("value");
The above coding will work fine
but wht u have specified rowId???? whether the "value" field is inside a af:table????? if so i have doubt on the above code's working.....

Can't get JSF to access managed bean methods from web page

I'm using NetBeans 6.7.1 and Glassfish v2.1
Having problems here can somebody please help? It is really
frustrating because I have written apps like this before in fact I
used one as a model to create an even simpler app and still can't get
it to work. I ran it through the debugger and it stops in the
constructor so it looks like the bean object is being created, but the
setUid method and the testit method are not being entered when I click
on the enter commandbutton. Can somebody PLEASE give me an idea as to
what might be going on? I am totally stumped and this is holding up
some important work I need to get done. Any help would be greatly
appreciated:

How to access backing bean of a xml component , in a managed bean of ADF

Hi,
We wrote a xml component in JSF and this component is used in ADF project by including the component as jar .
In a master detail page , we need to update the value of the xml component, when the master row is changed. How to do this.
We are trying to do this by accessing the backing bean of the xml component in ADF project's managed bean. So when ever the row changes, we can access the managed bean in ADF and then can set the value of the xml component by accessing it's backing bean
But i can't access the backing bean instance of the xml component in the ADF managed bean. Could you let me know how to do this. Thanks .

Thanks for the response Shay. The xml component is added as a custom component , with a separate faces-config.xml file . This component is added to ADF project as a jar with a custom tag.
In the ADF project , i'm having different managed beans and i can access them from a different managed bean.
The issue is, i can't access the added custom component's backing bean which is available from a different jar , defined in a separate faces-config.xml file . This backing bean is defined with request scope.

How to call partial trigger on JSFF component from separate managed bean?

Guys and Gals,
Using JDev 11.1.1.2.0. Looked on the forums and google. Initial results aren't so great.
Is it possible to call a PPR on a JSFF component from a separate managed bean? It seems calling the FacesContext in this instance calls the root JSPX, which only contains one child: the RichDocument.
      UIComponent component =
         FacesContext.getCurrentInstance().getViewRoot().findComponent("pc1:table1");
      if (component != null)
         AdfFacesContext context = AdfFacesContext.getCurrentInstance();
         context.addPartialTarget(component);
      System.out.println(FacesContext.getCurrentInstance().getViewRoot().getChildCount());Returns 1 :(
Ideas for a workaround?

Thanks! Joonas, you've been a great help.
The code on the page you referenced was close, but the code on a page referenced in the user comments was even better:
http://www.jroller.com/mert/entry/how_to_find_a_uicomponent
My region is located in a facet, which the page you posted doesn't quite cover, but the page above fixed that. Here's the fix below:
In Managed Bean
      // search for the region ID (or task flow) in the base page
      UIComponent base = jsfUtils.findComponentInRoot("dynamicRegion");
      // now find component ID from within that region
      UIComponent partTable = jsfUtils.findComponent(base, "partTable");
      // call PPR on your found component
      AdfFacesContext.getCurrentInstance().addPartialTarget(partTable);In JSFUtils utility class
   // used to locate region. Could also find any component
   // located in the base ViewRoot()
   public static UIComponent findComponentInRoot(String id) {
    UIComponent component = null;
    FacesContext facesContext = FacesContext.getCurrentInstance();
    if (facesContext != null) {
      UIComponent root = facesContext.getViewRoot();
      component = findComponent(root, id);
    return component;
    // Recursive method which finds your component within JSFF
    // regardless of facet or other UIComponents which may have children
public static UIComponent findComponent(UIComponent base, String id) {
    if (id.equals(base.getId()))
      return base;
    UIComponent kid = null;
    UIComponent result = null;
    Iterator kids = base.getFacetsAndChildren();
    while (kids.hasNext() && (result == null)) {
      kid = (UIComponent) kids.next();
      if (id.equals(kid.getId())) {
        result = kid;
        break;
      result = findComponent(kid, id);
      if (result != null) {
        break;
    return result;
}Good stuff to know!

Error while opening a popup from managed bean

Hi,
I am trying to open a popup from bean, after another popup is closed. When I open the second popup either through ActionListener(on first popup button) or DialogListener(on first popup), I am getting the below error on browser status bar(!); and the second popup doesn't open. There is no error in the log.
*'AdfPage.PAGE.findComponent(...)' is null or not an object.*
Although the popup id is there on the jspx page.
<af:popup id="confirmationStatus" binding="#{MyBean1.confirmationStatus}">
<af:dialog cancelVisible="false"
closeIconVisible="false" binding="#{MyBean1.d2}"
title="Appointment Confirmation Status">
<af:outputText value="Appointment is successfully confirmed"/>
</af:dialog>
</af:popup>
public void confirmAppointment_dialogListener(DialogEvent dialogEvent) {
FacesContext context = FacesContext.getCurrentInstance();
ExtendedRenderKitService service = Service.getRenderKitService(context, ExtendedRenderKitService.class);
String popupId = "confirmationStatus";
service.addScript(context,"AdfPage.PAGE.findComponent('" + popupId + "').show();");
Please tell me why my popup is not getting open from the managed bean and I am getting an error in below line.
service.addScript(context,"AdfPage.PAGE.findComponent('" + popupId + "').show();");

To find out the right address of a component related to an other component, open your page select the component you want to add a partial trigger, go to the partial trigger property, select the down arrow at the right end and select 'Edit'. Now look for the popup in the component tree shown on the left side. When you have found the popup shuffle it the the selected side and click OK. The string you see in the field is the full address of the popup related to he component you've selected. Try the string you see there in your bean code. Remove the string from the partial trigger property, it's just to get the correct path.
One other thing to check is that your popup has the ClientComponent property set to true.
Next thing to try, is to use AdfPage.PAGE.findComponentByAbsoluteId(...)

ADF Faces: Managed Beans

Hi All,
I have a situation where i need to pass the value to managed bean at runtime which inturn changes the values of menubar,menulist please can any one help me out.
Regards
Manasa Chanda

What you probably want to do is expose the menubar.menulist component to your managed bean. This is fairly easy to do by editing the "Binding" property of the component. This will let you specify a Managed Bean, and a Property, or you can press a New button to create the bean, and/or the Property. Once you've exposed the component, the properties of the component are available through EL, including being able to change those properties from other components.
