ADF 11: problem by invoking the backing bean popup

• Invoke the backing bean AM prior to the loading of the page

  I have a situation where I need to access the Module from the Application of a bean of support before any loading of the page.

  The method I currently use is:

  AppModule = ADFUtils.getApplicationModuleForDataControl ("MyAMDataControl") (MyAMImpl);

  This works very well if a page in the package that contains has been loaded first. My use case requires us to make that call until all pages in this package have been loaded (and thus AM has not yet been invoked). Any attempt to enter the AM using this method just leaves us with a null object.

  Is there a way to get around this?

  Edit: work with JDeveloper v11.1.1.6.0

  Hello

  both glued by Vinay links are no good solutions for this use case because they don't distinguish between initial and subsequent page rendering rendering (for example applications of PPR). Using the controller in the region, is really not easy to tell when the page rendered first time if you do not work with memory (stored in viewScope) flags.

  If you can, use a method call activity as proposed for the stubborn workflow. Be sure to call dispose method of a created file PageDef activities (click of mouse button allows you to create a law) fault what the method is not part of the life cycle ADF

• Create table ADF on the backing Bean page

  Hello
  I am currently able to recover and iterate/modify the data of a base of the Interior of the module of the Application manually (storing the changed data in a table). How ever I don't know how to put these data from the Module to the Application page that called? I'm assuming that I need the method that is called to return an CoreTable that would be then displayed on the page. It is the right approach and how would I go to do this?
  
  Thank you

  Hi Steve,.

  There are several ways to do this:

  -With the help of your:
  a. entity create and display objects to database tables and then add objects to view the module of the application
  b. drop the View object in the data as ADF Table control palette in the jspx page
  c. you can also drop some operations like CreateInsert(for insertion), remove, Commit, Rollback etc.
  d. If you want to perform operations on existing data, you can write a single method in AMImpl or VOImpl and modify the view object by the criteria of view running or where clause, then call this method from jspx page by exposing to the client interface

  -Programmatically binding value to table:
  a. create a method in AMImpl and return the records in the list and exposing it to the client interface
  b. Add the binding of the method in page jspx
  c. write a method in bean which return ListDataModel and link it to the value property of the table
  d. inside the bean method, call your AM method in getting the operationBinding
  e. give the list returned by the AM method to the listDataModel.setWrappedData method

  -You can prepare the entire table in the bean and then can link it to the table using the bindings property
  Among all the three ways, according to me, the first one is effective and simplest, you can choose one based on your requirement

  You get only one or the other in this task you mention. If your process definition contains "Update UD_LDAP_USR" as a name for the task, it will still work to update any field. If you want tasks to run individually on a change, rename this task as "TEMP UD_LDAP_USR updated" so it does not fire.

• Problem with invoking the Application Messages

  Hello

  I'm testing an application that adds an element of application menu in the list of messages and when clicked, displays just the old content and beneficiaries on the screen 'Compose Email'.

  That's what I did.

  public Object run(Object in_objContext)
  {
     if(in_objContext instanceof Message)
     {
      Message msgOrig = (Message)in_objContext;
      try
      {
          Message msgNew = msgOrig.reply(true,true);
  
          Invoke.invokeApplication(Invoke.APP_TYPE_MESSAGES,
              new MessageArguments(msgNew));
  
      }catch(Exception e){}
     }
     return null;
  }
  

  The problem is, there is no "Send" command in the context menu.

  Can someone help me?

  I can confirm that, but you're probably referring to my post on the other forum anyway.

  What you will find (if the memories are good) is that a message created with the Message.reply () function object doesn't have a 'Send' menu item when the envoys to the Messages app.

  However, I think you will find that the method of 'memory' works.

  What we ended up doing are creating our own processing of the Message object to generate a response object.

• ADF Mobile: How user Bind for Backing Bean UI elements

  Hello
  
  Is it possible to access UI element such as the PanelGroupLayout of the bean of ADF Mobile support? I would like to gain access to its properties and methods.
  
  Thank you

  estt wrote:
  Thank you for your response. We expect hide or show a PanelGroupLayout according to the preferences. If the user defined in the preferences, the necessary information, we will hide the Panel, show otherwise.

  You can set an attribute in your bean that contains the value 'true' or 'false' and use this attribute to the attribute that is made for your PanelGroupLayout component.

• How to use the backing bean method to show the outputtext value?

  things not clear is how init outputtext value if the bound property is not initialized.
  (the page opens but the values is null, need to call the getter before sort method)
  page view code:
  < af:outputText value = "user name: #{backingBeanScope.backing_page1.loginuser}" id = "ot11" / > "
  
  the corresponding code to support bean:
  private String loginuser.
  ...
  public String getLoginuser() {}
  return loginuser.
  }

  You need not call it yourself. Just put it on the page. When the page is rendered, it calls the method automatically.

• How to develop the Table of Backing Bean tree nodes?

  I have a requirement where I want my table to be expanded all three nodes. InitiallyExpanded = True develops alone.
  Is it possible to have all the Backing Bean nodes?
  
  Code snippet will be very useful.
  
  Thanks in advance,
  TK

  For all nodes in a treetable can be expanded, you will need to add all the rows of the disclosedRowKeySet.

  (1) create a binding for the treetable in average managed code as "treeTable.
  (2) create a CommandButton named "Expand" (under the picture of the tree) and Visible set to false and create a link to a page named expandButton & in the get accessor for the commandButton control method, call the following method:

  public RichCommandButton getExpandButton() {}
  this.expandTreeTable ();
  }

  private RowKeySet disclosedTreeRowKeySet = new RowKeySetImpl();

  private void expandTreeTable() {}
  If (this.treeTable! = null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  Model CollectionModel = (CollectionModel) treeTable.getValue ();
  JUCtrlHierBinding = treeBinding
  (JUCtrlHierBinding) model.getWrappedData ();
  JUCtrlHierNodeBinding RootNode = treeBinding.getRootNodeBinding ();
  disclosedTreeRowKeySet = treeTable.getDisclosedRowKeys ();
  If (disclosedTreeRowKeySet == null) {}
  disclosedTreeRowKeySet = new RowKeySetImpl();
  }
  List = firstLevelChildren
  rootNode.getChildren ();
  for (node JUCtrlHierNodeBinding: firstLevelChildren) {}
  List ArrayList = new ArrayList();
  List.Add (node.getRowKey ());
  disclosedTreeRowKeySet.add (list);
  expandTreeChildrenNode (node, treeTable, list);
  }
  treeTable.setDisclosedRowKeys (disclosedTreeRowKeySet);
  }
  }

  Private Sub expandTreeChildrenNode (RichTreeTable, rt,
  JUCtrlHierNodeBinding node,
  The list parentRowKey) {}
  ArrayList children = node.getChildren ();
  List rowKey;
  If (children! = null) {}
  for (int i = 0; i)< children.size();="" i++)="">
  rowKey = new ArrayList ();
  rowKey.addAll (parentRowKey);
  rowKey.add (((JUCtrlHierNodeBinding) children.get (i)) .getRowKey ());
  disclosedTreeRowKeySet.add (rowKey);
  If (((JUCtrlHierNodeBinding) (children.get (i))) .getChildren () is
  null)
  continue;
  expandTreeChildrenNode (rt,
  (JUCtrlHierNodeBinding) (node.getChildren () .get (i)),
  rowKey);

• Portlet backing bean

  Hello
  How the backing bean portlet to display the user interface for view.jspx objects? I have a table in my portlet view.jspx. I want to get the current line of the bean support. If I get the table object in backing bean, I can get it directly from backing bean.
  
  Thank you
  $N

  You must first create a java class. Save this java class in faces-config.

  Your class should look like this:

  package portlet.beans
  
  public class MyBean
  {
      private RichTable tbl;
  
      public RichTable getTbl(){return tbl;}
      public void setTbl(RichTable t){tbl = t;}
  
       public void doSubmit(ActionEvent e){
          Object o = getSelectedRow();
           //Do something
        }
  
      public Object getSelectedRow(){
         return tbl.getSelectedRowData();
      }
  }
  

  The code in your faces-config file look like

   
      myBean
      portlet.beans.MyBean
      session
    
  

  You JSPX will look something like this:

     
        ...
     
     
  

  Additional information on beans managed: http://download.oracle.com/docs/cd/E17904_01/web.1111/b31974/web_getstarted.htm#CACCFIII
  (the talkes information adfc-config, but you can apply to the faces-config. The big difference is that adfc-config is used for the purposes of the ADF and faces - config.xml is standard JSF. You cannot use adfc-config in a portlet to producer)

• [Beginner] Best practices for Backing Bean, data binding

  Hello world
  
  
  I followed a course of oracle in November ' Oracle Fusion Middleware 11g: Creating Applications with ADF I '
  
  Awesome, now I know what are the different parts of the framework.
  
  But now, I would go a little in depth.
  
  Here's a simple example
  
  Login page
  Backing Bean
  Session Bean
  Read only the View (the view selection) object
  Application module
  
  We have a user name and password in a table, but the password is encrypted in the column, in fact, is the checksum of the password.
  
  Here's what should be done.
  
  Login (username, password) Page-> proceed button-> to get the data of VO-> compare usernames-> transform password from the login page (MD5)-> compare him the password of database->
  assignment of params session bean-> redirect to Connexion2 page.
  
  Here's what I actually
  
  I have an AM listening with a java class having a doLogin (String username, String password) method with a return value of string.
  
  This method is exposed to the UI via a client interface.
  
  Here are my questions.
  
  Where can I check and turn all these params. In playback only VO via a class Java tuned, which extends ViewRowImpl or listening AM class java?
  
  And now for the session bean where I have to instantiate. I guess the Backing Bean.
  
  Wouldn't be better to call the client interface of the bean to support, then instantiate the session bean, with params from AOS, in this BackBean.
  
  I so much question that I don't know where to start. :-(
  
  Sincerely for your help.
  
  Senecaux Davis

  Hello

  If you want to keep the information for the duration of session, create a managed bean and configure it to session scope. If you need to access you can use EL directly or from Java in another managed bean (or bean backing) whereby the bean is instantiated. You can also use managed properties to pass the reference of a bean to support session bean.

  As for the location of the method, you must use a View object to query the user table just the user name. You read the encrypted password (assuming a single user entry is found) and compare it with the provided password. You return true/false value and use an OperationBinding in a bean managed to access the customer interface method through the ADF (action method) link layer

  OperationBinding operation = bindings.get ("login") (OperationBinding);
  operation.getParamsMap () .put ("username", username);
  operation.getParamsMap () .put ("passwd", pw);

  Boolean result = operation.execute ();

• Change Guide to Fusion? Creation of opening WLS for Backing Bean Code

  I noticed between the 11.1.1.1.0 and 11.1.1.2.0 Developer Guide of JDev for a subtle change to the code example for a connection programmatically in via WLS:
  
  First note '29.7.2.1 Creating connection to the Backing Bean Code' section of the 11.1.1.1.0 step 4 doLogin method():
  http://download.Oracle.com/docs/CD/E12839_01/Web.1111/b31974/adding_security.htm#BGBFJJJH
  
  Secondly, notes that same named section 30.7.2.1 6 simplified again doLogin():
  http://download.Oracle.com/docs/CD/E15523_01/Web.1111/b31974/adding_security.htm#BGBFJJJH
  
  Specifically, I note in the new 11.1.1.2.0 points out the subtle inclusion of ServletAuthentication.generateNewSessionID (request);
  
  What is what and what is the effect on my request to ADF?
  
  I ask, because we use the example of Steve Muench 129 for dynamic JDBC connections + programmatically the user connection based on the 11.1.1.1.0 notes. For some reason any code of Steve is thrown:
  oracle.jbo.InvalidObjNameException: Houston-25005: view.pageDefs_myAppPageDef object of type Binding definition of the form name is not valid.
  
  .. .when ever I add all links to my pageDef to the page that requires authentication. Go debugging it looks like the JdbcPagePhaseListener is called at a time when the definition of page files will still be initialized (well, that's a guess). This leads me to believe the 11.1.1.1.0 original method of logging via the WLS is not something properly to the connection needed by the ADF.
  
  Can someone give more information above why the doLogin() in the merger Guide method changed between versions please?
  
  With our thanks
  
  CM.

  Hi Chris,

  Wow! Your so quick that you have noticed that there is difference. :)
  I just noticed the note on the line with difference as follows:

  Line 11 ensures that the session for the session ID is changed after the user is successfully authenticated. This is necessary in order to avoid leaving the application open a session fixation attack, that would be a security breach.

  I hope someone can explain that.

  Kind regards

• Creation of backing bean.

  Hello
  
  I created a page of jspx in jdeveloper with many components of layout and faces. While exposing the design of the page, I had checked "do not expose the backing bean UI components. Now, I feel the need to expose the elements on the page to the bean packaging. I'd rather not do the getter and setter for each user interface component manually as there are a about 30 user interface elements on the page. Is it possible in jdev to put a bean in support for all components on the page?
