• ADF 11: problem by invoking the backing bean popup

  Hi all
  
  Using Jdeveloper 11.1.1.2.0.
  
  I use dynamic areas in my project. I am able to open the pop-up window of backing bean
  using following code: -.
  
  
  FacesContext facesContext = FacesContext.getCurrentInstance ();
  ExtendedRenderKitService service = Service.getRenderKitService (facesContext, ExtendedRenderKitService.class);
  service.addScript (facesContext, "AdfPage.PAGE.findComponent('pt1:ir1:1:rs_popupCreateApp').show ()");
  
  
  But the problem here is that "* 1 * ' in the ' pt1:ir1: * 1 *: rs_popupCreateApp" continues to change to * "0" or "3." So I have to change the code in backing bean giving pt1:ir1: * 0 *: rs_popupCreateApp or pt1:ir1: * 3 *: rs_popupCreateApp respectively. Problem here is that the source component of the (which invokes the popup) is a declarative resuable component of the button, and so I can't even add af:showPopupBehavior in that. Id of the source component run-time is 'pt1:ir1:1:rs_ort1:ox_tb_cb3', where the id of the target component is "pt1:ir1:1:rs_popupCreateApp".
  
  Please suggest code should I put in my two cents support this popup will appear each time, even the id of the target component is changed at the time of pt1:ir1: * 1 *: rs_popupCreateApp to pt1:ir1: * 0 *: rs_popupCreateApp or pt1:ir1: * 3 *: rs_popupCreateApp.
  
  Thank you

  Bind the component to your backing bean and use component.*getClientId () * instead of hard coding the component id.

• How to get the current value of db in backing bean

  Hello
  
  I use jdeveloper 11.1.2.3.0
  
  I would like to know how I could access the old value of an attribute in backing bean.
  I know I can get it in terms of EntityImpl with the getPostedAttribute function,
  but as I see that I'm not allowed to access this function in the ViewImpl.
  I get this error:
  Error (151,33): getPostedAttribute (int) has protected access to oracle.jbo.server.EntityImpl.
  
  Could you help her?
  What is the right way to get the current value on db in backing bean?
  
  Thank you very much!

  You can add a transitional attribute to the entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

• Get the value of the bind variable in backing bean class VO Impl

  Hello
  
  I have a VO that includes a bind "pOrgId" variable, the VO has a java VO Impl class that includes:
  
  /**
  * Returns the value of the variable to pOrgId.
  value of the variable * @return for pOrgId
  */
  public {getpOrgId() number
  return (Number) ensureVariableManager () .getVariableValue ("pOrgId");
  }
  
  So it is possible to obtain the value is concluded by the binding variable using this class in a backing bean? (I tried to import the VOImpl class in the bean to support, but getpOrgId is not available?).
  
  (JDEV 11.1.2.3.0)
  
  Concerning
  Carl

  Hello

  When you create a ViewObjectImpl class, none of these options is to generate the getter/setter for bind variable. Create a client class interface and expose the get method for the variable binding. Now, you can reference the method since a binding method in the ADF, which you then access a managed bean by calling

    BindingContext bctx = BindingContext.getCurrent();
    BindingContainer bindings = bctx.getCurrentBindingsEntry();
    OperationBinding oper = (OperationBinding) bindings.get("name of the method binding");
    Object returnVal = oper.execute();

• Is it possible to call a custom method in the App Module to a backing bean?

  I would like to know if a custom in the App Module method can be called from inside of a pod of support.
  I don't know if it is logically just call, to a backing bean, a custom in the App Module method. But I would like to know if this is necessary or if it is possible.

  Hello..
  Yes it is possible. You must add this interface method customer of AppModule.Now you can see this method in data Controls(Refresh the data control). To call this method using bean, should be added as an action method links (click on links > + > methodAction > and create the binding of the action).
  Now, you can call this method in the bean class.

• 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)),

• The difference by calling an application to a backing bean module

  Hello everyone!
  
  
  I do not understand exactly, where is the difference by calling an application of a bean of the following support module.
  
  Example 1

  FacesContext context = FacesContext.getCurrentInstance();
  ValueBinding vb = context.getApplication().createValueBinding("#{data}");
  BindingContext bc = (BindingContext)vb.getValue(context);
  DCDataControl dc = bc.findDataControl("AppModuleDataControl");
  AppModuleImpl appModule = (AppModuleImpl)dc.getDataProvider();

  Example 2

  String amDef = "model.services.AppModule";
  String config = "AppModuleLocal";
  AppModuleImpl appModule = (AppModuleImpl)Configuration.createRootApplicationModule(amDef, config);

  Example 3 (same as example 1?)

  String EL = "#{data.AppModuleDataControl.dataProvider}";
  FacesContext fc = FacesContext.getCurrentInstance();
  ValueBinding vb = fc.getApplication().createValueBinding(EL);
  AppModuleImpl appModule = (AppModuleImpl)vb.getValue(fc);

  Please can someone explain, the three examples do? What kind of example is best to call an application-module to a backing bean method?
  
  
  Thanks and greetings
  Majo
  
  Edit: I use ADF BC 10g in JDev10 :)

  Hello

  BindingContext bctx = DCUtil.getBindingContext (request);

  There is nothing else that #{data}. Best is to always access #{bindings} El to get a handle to the binding object. This way you can be sure that the object exists and is instantiated.

  DCBindingContainer links =... solve #{bindings}
  BindingContext bctx = bindings.getBindingContext ();
  Control of DCDataControl = bctx.findDataControl ("Name");
  ApplicationModule m = control.getDataProvider () (ApplicationModule);

• Invoking the CreateInsert of a managed bean

  Hi all
  
  I'm trying to call a CreateInsert operation on a view of a method object in a managed bean. The method is assigned as the actionListener for a toolbar button. For this, I modified the file xxxPageDef.xml with the wizard, who introduced something like this:
  
  & lt; action = "CommercialReferenceVO1Iterator" id = "CreateInsertPepe" IterBinding
  InstanceName = "DesignRequestAMDataControl.CommercialReferenceVO1"
  DataControl = "DesignRequestAMDataControl" RequiresUpdateModel = "true".
  Action = "createInsertRow" / & gt;
  & lt; / code & gt;
  
  I invoke the method using the EL from Steve Muench class as follows:
  
  EL.invokeMethod ("#bindings. CreateInsertPepe.execute', null (class), null);
  
  I do something appropriate? Because the truth is, it does not work :)
  
  What I really need, is create and insert a new row into an object of the detail view, and then change the tab currently selected programmatically to display the edit page for the new line.
  
  I hope that my question is at least some logic...
  
  Thank you!
  
  Juan Manuel

  Try this code in your method of action/actionListener managed bean:

  OperationBinding createInsertOp = (OperationBinding)getBindings().get("CreateInsertPepe");
  createInsertOp.execute();
  

  The code only inserts the line. Programatically displaying the edit page for the new line it is something else. If my suggestion is to execute the code inserts really the only line. If its ok, then just add the code that automatiaclly displays the edit page. In this way we can isolate the problem.

  Make sure the CommercialReferenceVO1Iterator is in the iterator header for the CreateInsert to work on a ViewObject detail.

  Another thing is that in your pagedef, I noticed the action links, the 'Action' attribute has the value "createInsertRow". You use charger 11 g? I don't know if its new in 11g but I use ADF 10 g and the attributes of 'Action' have numeric values, where a CreateInsert operation would have an Action = "40".

  Best regards

• 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.

• 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
  
  
  
  Steve

  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

• Manage the editable elements to read only by Backing Bean!

  Hello
  
  Updating JDeveloper/ADF 11 g 2
  
  I find that how to handle the editable by any listener action elements against button/link/object such solution.
  
  Details:_
  
  Suppose I have a table EMP VO entry form and want to show as read that during the form load, but when I will enter / click on a button (created manually) to change all items will be changed to edit. and after the present and commit files then everything appears as read-only.
  
  I want to manage read and editable only receding from class / listener of the action to change the button (created manually) . Is this possible? If possible, please give me such a solution.
  
  Please help me.

  OK, here you go:
  Code of the bean (put the bean in the flowrate of session or page range):

  package demo.clickenable;
  
  import javax.faces.event.ActionEvent;
  
  import oracle.adf.view.rich.component.rich.input.RichInputText;
  
  public class ClickEnableBean
  {
      Boolean enable = Boolean.TRUE;
  
      public ClickEnableBean()

      public void setEnable(Boolean aEnable)
      {
          this.enable = aEnable;
      }
  
      public Boolean getEnable()
      {
          return enable;
      }
  
      public void flipEnable(ActionEvent actionEvent)
      {
          if (getEnable().booleanValue())
              setEnable(Boolean.FALSE);
          else
              setEnable(Boolean.TRUE);
      }
  }
  

  JSPX page:

  The real work is done by a partial trigger button (id = box). This trigger is used to update the panelGroupLayout now the text input fields that are enabled/disabled via the Boolean value of the bean. Each click on the button toggles the Boolean value and updates the page.

• How the value of variable Page of Backing Bean

  Hi all

  New on ADF trying to access page variable value to a BackingBean (scope wonders).

  I tried this approach but does not work, I do not know how to solve.

  My ADF page is filled by a VO.

  It is the ADF page code:

  < af:panelLabelAndMessage label = "Name" id = "plam8" >

  < af:outputText value = "#{bindings." Name.inputValue}"id ="ot7">

  < / af:outputText >

  < / af:panelLabelAndMessage >

  < af:panelLabelAndMessage label = 'Start Date' id = 'plam8' >

  < af:outputText value = "#{detailBean.startDate.inputValue}" id = "ot8" / > "

  < / af:panelLabelAndMessage >

  This is the piece of my BackingBean where I need to read my element value and the format in right way and then push it down on the page of the ADF:

  private String startDate;

  public String getStartDate() {}

  StartDateXD = (Date) resolveExpression("#{pageFlowScope.startDate}");

  If (startDateXD ! = null) {}

  In the date format = new Date (startDateXD. getTime());

  SimpleDateFormat newFormat = new SimpleDateFormat("dd/MM/yyyy");

  startDate = newFormat.format (formatted);

  }

  Return dataSds;

  }

  Is someone coulfd help me?

  Thanks for your help.

  Fairlie

  Yes, you can use af:convertNumber to convert currency. Check Ashish Awasthi (Jdev/ADF) Blog: change of af: convertNumber Format according to the regional settings - Oracle ADF for a sample.
