Phase listener buries exceptions

• Phase listener does not

  Hi Experts/Timo,
  
  I'm new in Oracle ADF. I use the JDeveloper version 11.1.2.1.
  
  For the purpose of learning, I create a custom listener phase, here are the codes.
  Problem is when I ran to the window of console page not print anything on the phases.
  
  Below codes are written in adf - settings.xml
  
  <? XML version = "1.0" encoding = "windows-1252"? >

  Not only that when I clicked on the tab overview of the ADF - settings.xml is show only the Controller Configuration icon show as a model, business, MDS, controller components and see nothing else.
  
  When I run the console window of the page doesn't print anything on the phases.
  Please suggest me what's not here and that things are missing.
  
  Hi Timo,
  
  So many times you helped me could you please give your opinion for this problem?
  
  Thanks in advance.

  What is the path to your adf file - settings.xml? It should be under /.adf/META-INF

• Call the javascript of customized phase listener method

  Hey guys,.
  I am currently integrating an ADF with another web application custom application, for this - I wrote a custom listener phase and in its afterPhase() I need to call a javascript method, which will proceed with a treatment for me. For icefaces, we have something like com.icesoft.faces.context.effects.JavascriptContext.addJavascriptCall (facesContext, jsmethod); but I couldn't find something similar here in BAA. Advice/suggestions will be appreciated!
  Thanks in advance.

• Listener phase in the subsystem deployed as BTF in Master - jdev 11.1.2.3

  Hello:
  
  We use subsystems with BTF is deployed as ADFLibs. These ADFLibs of subsystem are imported into a master app and the BTF is used as a region in the Master.
  
  I tried to create a Phase listener that displays System.out.println msgs in the subsystem which was then used as a region in the Master app.
  
  But no message to the listener of Phase appears on the console. What Miss me? The Phase listeners must be in the Master app?
  
  What happens if I wanted the listener to the subsystem just Phase? Is this possible?
  
  Here is the code for adf - settings.xml and java class that implements PagePhaseListener:
  
  <? XML version = "1.0" encoding = "UTF-8"? >

  System.out.println ("getDebugValue =" + pagePhaseEvent.getDebugValue ());
  
  
  If (pagePhaseEvent.getPhaseId () == Lifecycle.PREPARE_RENDER_ID) {}
  System.out.println ("Lifecycle.PREPARE_RENDER_ID =" + pagePhaseEvent.getDebugValue ());
  FacesContext fctx = FacesContext.getCurrentInstance ();
  String viewId = fctx.getViewRoot () .getViewId ();
  FacesMessage message = new FacesMessage ("Hello Page number" + viewId);
  fctx.addMessage (null, message);
  }

  System.out.println ("at the inside of the beforePhase =" + pagePhaseEvent.getPhaseId ());
  System.out.println ("getDebugValue =" + pagePhaseEvent.getDebugValue ());
  }
  
  }

  First, make sure that the listener of phase works in the application of the subsystem.
  Second, once the master app consumes the child app (like adflib), set the stage listener in the Web.XML (within the masterapp).

  taskflow and face-config config files are combined, but I don't think that this is the case even for web.xml.

• phases of listener invoking doubts?

  Hi experts,
  
  I wrote a method named x in the request module it will return a string. I expose this method on the client interface.
  
  I called the x method using methodaction in my jsff.
  
  OK fine.
  
  I got jsff presented inside the stubborn TF
  
  I had my jsff some tabs Panel. clicking the jsff method I wrote had to be executed.
  

  public class x implements PhaseListener {
  ....
         public void beforePhase(PhaseEvent phaseEvent) {
          
          System.out.println("Before Phase");
         
          if (phaseEvent.getPhaseId() == PhaseId.RENDER_RESPONSE)
          { 
          BindingContainer bindings = getBindings();
          OperationBinding oper = bindings.getOperationBinding("Scheme");
          Object result = oper.execute();
          System.out.println("result" + result);
          if(result.equals("P"))
          {
              advReqFlag.setDisabled(false);
              AdfFacesContext.getCurrentInstance().addPartialTarget(advReqFlag);
          }
          
          }
          
        
      }
  
  ...
  }

  but he always returns the null pointer.
  If no written after phase no exception more but never executed
  
  error is explicit. but I impossible? How can I fix?

  Follow the steps below:

  1. create your pageDef for AM MethodActionBinding method.
  2 disabled = "."
  3. run the methodactionBinding in this method of bean.

  This works... I tested it in a sample application.

• What are the steps to set a listener to phase in JSF 1.1?

  Hi all...
  
  The implementation of a listener of the JSF 1.2 page (the one that comes with JDeveloper 11 g) is very simple, you implement the methods getPhaseID, beforePhase, afterPhase, and then add the class in the JSF configuration file. It works like charm.
  
  However, to do the same thing with JDeveloper 10.1.3.4 (it comes with JSF 1.1) never works... so I was wondering... Am I missing something? What are the correct steps to do this?
  
  Thanks in advance.

  Mustafa,

  Step 1: Create a phase listener
  Step 2: Enter in the faces-config file. XML

  [url http://balusc.blogspot.com/2006/09/debug-jsf-lifecycle.html] This is an old post that shows the steps (and then goes to show how use a listener of the specific phase to help gain a better understanding of the life cycle JSF).

• Phase problem event

  Hello

  I use jdeveloper Studio Edition Version 11.1.1.7.0,

  When I implemented the following code of the page does not not to any action.

  the code is:

  {} public void phaseEventFun (PhaseEvent phaseEvent)

  ExternalContext ectx =

  FacesContext.getCurrentInstance () .getExternalContext ();

  HttpServletResponse response = (HttpServletResponse) ectx.getResponse ();

  response.setHeader ("Cache-Control",

  "no-cache, no-store, must-revalidate");

  response.setHeader ("Pragma", "non-cache" "");

  response.setDateHeader ("Expires", 0);

  }

  anyone can give an answer, please

  Thank you.

  First, you must run the code in phase RENDER_RESPONSE (and not in all phases).

  Second, we know not if it is 'after' or 'before' phase listener (it should be forward phase)

  And third, phase listener is not good place to control caching (you must use servlet filter, or put a few proxy (like apache or nginx) and control the http headers it)

• Process Validations phase?

  Hello world

  It is said that in this phase the local values of the components are validated by treating all of the validators on the component.

  What validators will deal with this phase. Please give a few examples.

  Processes validations: the local values of the components are converted from the input type for the underlying data type. If the converter fails, this phase continues until the end (all the other converters, validators, and required controls are run), but in the end, breaks the phase lifecycle Render Response.

  If there is no failure, the http://www.blogger.com/blogger.g?blogID=294172151396534006required attribute on the element is checked. If the value is true and the associated field contains a value, then the associated validators are run. If the value is true and there is no value in field, this phase ends (all remaining validators are run), but the life cycle passes Render Response phase. If the value is false , the phase is completed, except if no value is entered, which case no validation is performed. For more information on the conversion and validation

  see this article

• Cannot find tag event listener in the nucleus of all JSF component category

  Hello
  In jdev 11.1.2.3,.
  
  I can't find the event listener tag in the category compenent of basis of the JSF component in the component palette.
  There are tags as a listner:
  -Action listener;
  -Phase listener;
  -Set Action listener property;
  -Listener value changes;
  
  Is there something wrong?
  Thank you!

  In the component palette, you can see a search field on the top of the palette. Hit and type of event in this entry. You get the 'event' as a result?
  Otherwise, open the project properties and open the node of "JSP tag libraries. Check who the library "JSF Core 2.0"in the section "Distributed libraries".

• Popup + before the stage listener + problem commandlink

  All,
  
  I have a phase listener configured on a page to open a popup and it works fairly well, i.e. the popup is open when the page is loaded. Now, I want to show the popup even when the user clicks on the commandLink. So I configured the commandLink to have a showPopupbehaviour as his child. The question is when I click on the order link that the popup is not opening. However if I remove the call to forward phase listener (), the popup is get called from the command link.
  
  Please advice what's wrong in this case? Ideally both should work independently.
  I tried to address the immediate and automatic submit also but no effect.
  
  thnks
  11.1.1.5 Jdev

  Hello

  using af: showPopupBehavior issues a request to the server, which then also is treated by your phase listener. Add some logic to your phase listener for does not work when you press the command button. You can for example define the command button on partialSubmit = true and then check if the request is a partial request AdfContext.getCurrentInstance () .isPartialRequest (facesContext) in this way the listener of phase opens the popup when a page loades but is no longer after.

• Get the values of default table row when the page loads

  Hello

  I am running JDev 11.1.1.7. We have a page that contains two tables in a relationship of the master / detail of nickname. We can do a real master ADF / detail with view items related because the query for the 2nd table is complex and works best when queries with binding settings. The View object for the 2nd table has a request with 2 link params as it can get in the first table. Thus, when a line is selected in the first table we want to execute ExecuteWithParams on the object from view of the table 2. We do it in the Bean managed for the page in a method that is the selection to the first table listener. It works fine except when the page initially loads, the first line is selected by default. When the default value is selected the selection listener is not triggered.

  I've seen the suggestion of not having a line selected by default when the page loads by removing the value selectedRowKeys on the table. However, we do not want that the 1st row of the table secondary master to be selected by default and we as the table of detail to show the correct corresponding lines.

  Steve

  Steve,

  Not really sure when you say that the 2nd table is complex and may not use the master detail. If the settings link in the parent table, you can set the ViewLink accordingly and it should work, right?

  In any case, if you're after the execution of methods on the loading of the page, you will find the links below.

  If it's a working group, you can add a methodCall as activity by default and UTF, you can use phase listener (if listener server does not).

• How to prevent the login page in the same browser when the user is already authenticated

  Hello

  I use Jdev 11.1.1.6 with ADF implemented in my application security.

  I have Login.jspx that redirects the user to Home.jspx on a successful authentication. The user can either enter the URL of the Home Page or Login.

  Please consider the following scenarios:

  (a) the user is not authenticated in the current browser session

  (a.1) if the user enters the URL of the home page and the login page is displayed and redirected to the homepage on authentication

  (a.2) if the user enters the login page URL, then the login page is displayed and redirected to the homepage on authentication

  (b) the user is already authenticated in the current browser session, a new tab opens and

  (b.1) if the user enters the URL of the homepage then it shows directly the (already authenticated) Homepage

  (b.2) if the user enters Login URL then connect a page appears - This is the issue, it should either user to the homepage or invalidate the existing session and let users to proceed again.

  How do I get there? Any help is appreciated.

  Thank you

  JAI

  Hello

  the authentication check must be in a phase listener or servlet filter. If you use a phase listener and the homepage and login have a link associated with the ADF (PageDef file) then in the phase AFTER RESTORE_VIEW, you can use AdfContext.getCurrent () .getSecurityContext () .isAuthenticated () to tell if a user is authenticated or not.

• ADF taskflow with not get every page refresh

  Experts,

  We have created a portal WebCenter ADF application.  The ADF taskflow with 3 pages on this subject.

  1. first page includes a data control that uses a session bean method that calls an external Web service.

  2. second page has a feature to view the details of a record that is selected on the first page.

  3. third page has a function to download a file.

  
  

  The user navigates and downloads a file, we redirecting them to the first page where the control data must display the list of issues.  The problem is that after adding a new record, and his return to the control of data page (which is a list of records), the newly added drive does not appear.  The only way to view seems at this point to ask the user to shut down and log in to the system and reactivate the workflow.

  
  

  We have a phase listener to clean the cache, in the hope that it could solve the problem.  But it does not.

  
  

  Any ideas or advice on how to automatically refresh the data in control when the user navigates to this page?

  
  

  Thanks in advance.

  Sam.
  

  In the links page, verify all conditions of discount on the data control.

• method of appeal as soon as the user is connected to the webcenter Portal

  Hello

  What would be the best place to call a java method as soon as the user is authenticated (connected) - before first connected page.

  I need to pick up the profile of the user to the ldap server.

  I use this bean OOB for login - oracle.webcenter.security.view.login.LoginBackingBean

  Thank you.

  Hello.

  ADF Phase listener uses are common in ADF, and WebCenter portal projects. You need to implement carefully for performance stuff.

  In our case we have implemented something like

  public void beforePhase(PagePhaseEvent pagePhaseEvent) {
          if (pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_MODEL_ID){
              UserBean user = (UserBean)ADFContext.getCurrent().getExpressionEvaluator().evaluate("#{c_i_p_b_userBean}");
              // Only if user information weren't loaded
              if (user != null && user.getUserPrincipalName() == null) {
              // Only if the users is really authenticated
                  if (ADFContext.getCurrent().getSecurityContext().isAuthenticated()) {
                      // Fill User attributes in the scoped variable
                      LDAPUtil ldapUtil = new LDAPUtil();
                      String userName = ADFContext.getCurrent().getSecurityContext().getUserName();
                      ldapUtil.getUserBasicAttributes(userName,user);
                  }
              }
          }
      }
  

  By running this code before PREPARE_MODEL_ID will mean that only will be implemented during the first page of loading time (not in the PPR requests).

  It does not affect performance.

  I hope this help you.

  Kind regards.

  For that I have referred to the metalink Note ID 1103163.1 is suggested here problems running autoconfig on db level
  and found that
  * # $Header: adcvm.sh 120.3.12010000.2 2008/09/23 05:30:32 rdamodar ship *.
  * # $Header: 120.15 adbldxml.pl 12/03/2008-17:10:12 subhroy ship $*.
  Instead of (should according to the note ID 1103163)
  adcvm.sh 120.3.12010000.5
  adbldxml.pl 120.15.12010000.5
  
  so I try to apply the Patch
  patch 8919489 R12. T2K. B.Delta.3
  patch 9852070 R12.TXK.B
  
  But since Installation of the EBS r12 is 40%... then apply the Patch AD is not possible because there is just no App_TOP or is not entirely created yet.
  
  Could someone please tell what is the workaround here.
  
  
  Thank you

  Please re - check again...
  Linux 6 is not registered with DB 11.1.0.7
  Linux 6 is certified with EBS R12.1.1
  .
  If you want tobe on Linux6...
  .. then to have DB 11.2.0.3 first, then plan to have EBS R12.1.3 installation on top of the DB 11.2.0.3
