The create method call in managed beans

• a class of EOImpl create() method call

  How do I pass and AttributeList to the create of an EOImpl class method if the method is not called directly? Is it true that when you call vo.createRow (), the create() method is called automatically? If so, vo.createRow () accepts no arguments.

  Just set the values of attribute in line with VO, and it would automatically create in the EO line.

  row.setAttribute ("AttributeName", value);

  In case you have typecasted your line to the voRowImpl type, you can do it like this:
  Row.Set(value);

  Please don't bother about how values are themselves defined in the EO (if your goal is to get the functionality and not the technology).

  // get the binding container
  BindingContainer bindings = BindingContext.getCurrent().getCurrentBindingsEntry();
  
  // get an ADF attributevalue from the ADF page definitions

• [ADF, JDev12.1.3] How to display a gif of loading during the loading of the af: table (through the ExecuteWithParams method call)?

  Hallo,

  in the fragment of my page, I created an af:table you drag an instance of VO for the data control; I also have a search button by dragging the operation ExecuteWithParams of the same instance of VO.

  I double clicked on the serach button to create the searchButton_action method in the bean calling the ExecuteWithParams operation after you have made a few operations.

  Next to the button, I put a table whose source is a gif of "load".

  I would like to make visible the gif while research is underway and make it invisible when the search is complete.
  

  
  

  In the beginning, I followed this approach.
  

  In the searchButton_action, I wrote the code to set the visible of the image property.

  But it did not work because the gif never appears. I also tried to set the property PartialTriggers of the image with the ID of the button table and search.
  

    public String searchButton_action() {
      RichActiveImage imgSearch = (RichActiveImage) FacesUtils.findComponent("ImgSearch");
      imgSearch.setVisible(true);
      AdfFacesContext.getCurrentInstance().addPartialTarget(imgSearch);
      // ...
      OperationBinding operationBinding = BindingsUtils.getBindings().getOperationBinding("MyVOInstanceExecuteWithParams");
      // ...
      imgSearch.setVisible(false);
      AdfFacesContext.getCurrentInstance().addPartialTarget(imgSearch);
      // ...
    }
  

  Then I tried with another approach which is to set the Visible property using the value off of the search button which is #{! links.} MyVOInstanceExecuteWithParams.enabled}

  But also, this approach has not worked.

  I also tried to set the property PartialTriggers of the image with the ID of the button table and search.

  What's not in my efforts? You could you kindly help me to solve the problem?

  Thank you

  Federico

  PS

  FacesUtils.findComponent is a method that retrieves the item passed as param. It works well since I used it several more times in my application.

  Your approach may not work add there is only a single thread of UI work. Your trigger reached the component when the execute with Péan has finished its work.

  For your use case there are a few solutions combining JavaScript and client-server events showing a window as long as the operation is running. Read https://blogs.oracle.com/groundside/entry/notification_during_long_running_transactions for all the info.

• The same method works OK a bean, cause of error in another

  For the experienced:
  
  I use JDeveloper 10.1.3.4 and the backup of a page bean, to get an instance of a module application I do this way:
  

      public ZBOVStaffModuleImpl getZBOVStaffAm() {
          FacesContext fc = FacesContext.getCurrentInstance();
          ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
          BindingContext bc = (BindingContext)vb.getValue(fc);
          DCDataControl dc = bc.findDataControl("ZBOVStaffModuleDataControl");
          ApplicationModule am = (ApplicationModule)dc.getDataProvider();
          return (ZBOVStaffModuleImpl)am;
      }
  
      public String commandButton1_action() {
          ZBOVStaffModuleImpl zbovStaffModule = getZBOVStaffAm();
          // ... lines omitted
          return null;
      }

  Before you add only one line in the commandButton action method, it can be called and clicked commandButton1 without causing any problems. Now, simply by adding a line that calls the getZBOVStaffAm() method when you click commandButton1, I got the error in the browser:
  

  javax.faces.FacesException: #{staffLogin.commandButton1_action}: javax.faces.el.EvaluationException: java.lang.NullPointerException

  I removed the line in the commandButton1_action() method and copied the lines of the getZBOVStaffAm() to the commandButton1_action() method method, one line at a time and run the pages and found that when this last line shown here is added, the error has been spilled in the browser:
  

      public String commandButton1_action() {
          FacesContext fc = FacesContext.getCurrentInstance();
          ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
          BindingContext bc = (BindingContext)vb.getValue(fc);
          DCDataControl dc = bc.findDataControl("ZBOVStaffModuleDataControl");
          ApplicationModule am = (ApplicationModule)dc.getDataProvider(); // line causing problem
          // ...
          return null;
      }

  I have no idea why this line would spill error. The getZBOVStaffAm() method is copied word for Word from another bean of support, and in this bean support, this method is called in the same way but has not caused any problems. I checked doulbe ZBOVStaffModuleDataControl data control name is correct. Hope that experienced developers would have some suggestions.
  
  My application is in two parts. For the part of the student, the application module is ZBOVModule. During the construction of the part of the staff, I added the ZBOVStaffModule and built pages and tested features, without joining them with cases of navigation. The bean to support one of these pages, I created this getZBOVStaffAm() methods to avoid repeating the same code. And it has worked very well.
  
  Now all these pages are built and worked, I restarted right at the end of the part of the student, created a diagram vacuum staff-faces - config.xml for testing each reconstructed page, adding the login page and join them in case of navigation. But leader, in the first two pages involving login and required the use of the getZBOVStaffAm(), I went to the problem described above.
  
  Thanks a lot for your help!

  Hello Newman,

  I see nothing wrong in your code.
  Do you have links in your pagedefinition? If this isn't the case, you can try adding just a few link by drag / drop some attribute on the page and see.

  Sometimes back I faced the same question when I don't have the links in my pagedefinition and adding a component and linking to some datacontrol method/attribute this problem resolved. Not sure if this is a bug, but you can give it a try.

• Need help: the Get method call / EOImpl

  Hi refugees,

  Gud morning question,.

  I have two classes of EOImpl,

  As I am new to OFA, I am facing problem while

  calls the method to accessor Get EOImpl one in the other accessor method Set EOImpl...

  Can we call that?

  Requirement: I have two EO with the column Header_Id

  I have to give the same value in both columns

  In the first EOImpl class, I used the sequence in the Set accessor method.

  Now, I have to call the accessor method Get EOImpl first in the second accessor method Set EOImpl...

  Please give your valuable suggestions...

  Thank you

  Jaya

  Hello

  You can set the value of EO header_id 2nd in your AMImpl.

  While creating the line for the 2nd VO, get the value of header_id 1 VO and the use of the row.setHeaderId () value before VO.insertRow.

• Information on the current user in a managed bean

  I replaced prepareSession in a Module of the Application (AM) so that when a user connects to my application, it immediately uses the user name as a variable binding to execute the query for a view object (VO) that gets more information about the user, such as full name, e-mail address... It works fine and I am able to bind the VO to a page and display the information.
  
  But now I begin to realize I'm going to need this information to the user through the application. What I do include an iterator for the info user VO and attributeValues related each unique pageDef, or is it possible to write a single managed bean that will expose the attributes of the single line of the VO as properties. The application I'm working now on East a "minor" update to apply JDeveloper 10.1.3, so I need a 10.1.3 solution, but I have a 11.1.2 application in the works that will probably do the same thing.
  
  Oh and sorry if this is a FAQ - I probably not use search terms to find solutions that have already been posted.

  Here, little code extracted from our implementation:

  public class SessionInfo implements Serializable {
  
      UserInfoModuleImpl module;
      private String SUNAME = null;
  
      // in constructor, save a reference to the AM used to retrieve the user information
      public SessionInfo() {
          module = (UserInfoModuleImpl)ADFUtils.getApplicationModuleForDataControl("UserInfoModuleDataControl");
      }
  
      // getter to return user's name
      public String getSuname() {
          // retrieved only once from the database
          if(SUNAME == null) {
              // notice that getSuname() is an AM method exposed to its client interface
              SUNAME = module.getSuname();
          }       
  
          // return cached value
          return SUNAME;
      }
  }

• Question about the use of JavaScript in Managed Bean

  Hello
  
  I have two questions... The reason for these questions is: we have a requirement that we have executed successfully using jsp and javascript. Now, we are unable to be implemented using the framework of the ADF. It is why would have a jsp with javascript page to reach the requirement.
  
  The condition is:
  1. to print a page. This page should be displayed with a customer bills. If the customer has 3 invoices (html content), these 3 bills needs displayed on the screen with a page break.
  2. because the page has a lot of data, certainly there will be a right of the page scroll bar to scroll down to see the data.
  3. now, the user clicks on the file--> print available on the browser / provided a "print" button with < af:showPrintablePageBehavior / >. When this happens, it is able to print the data that is displayed on the screen, not all 3 bills.
  
  This kind of requirement we already implemented using legs force Framework(jsp,java script).
  
  Now my question to you is:

  how we can open a new window bowser using java from a managed bean script.

  Let me know if you need more information about it.

• How to get the value of varStatus in managed Bean

  Hi all

  I use jDeveloper 11.1.2.4 version.

  I had a table with table with departments view object. I added an extra column to the table to display the serial numbers of the lines like this.

  < af:table...

  varStatus = 'vs' rowSelection = "multiple" id = "t1" binding = "#{ReferenceBeans.departmentTable}"> "

  < af:column id = "c5" headerText = "varStatus" >

  < af:outputText value = "#{vs.index + 1}" id = "ot1" binding = "#{ReferenceBeans.varStatus}" / > "

  at the bean, I get all the values of the selected line, but I don't get the varStatus value of the column.

  If I use

  Object varStatus is getVarStatus () .getValue ();.

  System.out.println("varstatus::"+varStatus);

  That's the impression first value only, but not the values of the selected line.

  

  How to get the varStatus value in the bean selected lines.

  Best regards

  Claude Reynier.

  You can get the index of the line of the ViewObject.getRangeIndexOf (row) method. Something like this:

  empIter.getViewObject () .getRangeIndexOf (currentRow)

  example:

      RowKeySet selectedEmps = getTable().getSelectedRowKeys();
      Iterator selectedEmpIter = selectedEmps.iterator();
      DCBindingContainer bindings = (DCBindingContainer) BindingContext.getCurrent().getCurrentBindingsEntry();
      DCIteratorBinding empIter = bindings.findIteratorBinding("EmployeesView1Iterator");
      RowSetIterator empRSIter = empIter.getRowSetIterator();
      while (selectedEmpIter.hasNext())
      {
        Key key = (Key) ((List) selectedEmpIter.next()).get(0);
        Row currentRow = empRSIter.getRow(key);
        System.out.println("FirstName" + currentRow.getAttribute("FirstName") + "  - Row Index= " + (empIter.getViewObject().getRangeIndexOf(currentRow) + 1));
      }
  

• How to use Groovy to the attributes of access on managed Beans?

  What is the best way to define view object Bind variable values that are not exposed by the entity object? More specifically, I have an entity with a values list object attached object. I need to set a value on the a Bind Variable views LOV ", which is not a value on line' oppose?

  You should not access properties of interface layer user directly from your model layer - because it would break the independence of the model using a specific user interface layer.
  Instead, expose a service method on the VO or AM that accepts a parameter and sets the binding variable - and then call this method in your user interface.

• Lets get the user name in the workspace of BPM ADF Managed Bean

  Hi all
  
  I used JSF, and ADF to build the user interface for the task. And I want to get the user name of the user who is handling on workspace of BPM. For example, an ADF form may display the username of the current user in the workspace of BPM. I also try this approach: use handle Bean and bind this bean to a text output in the form of the ADF. The code fragment that I use to get the current user name is:
  ADFContext.getCurrent () .getSecurityContext () .getUserPrincipal () .getName ();
  
  But it does not work. The value I get is anonymous.
  
  So, please help me solve this problem

  Hello, please try this feature as below:

  public String getUserLogin() get WorkflowException,
  BPMIdentityException,
  {BPMUnsupportedAttributeException}
  String userId = "";
  IWorkflowServiceClient wfSvcClient;
  ITaskQueryService queryService.
  IWorkflowContext wfContext;

  Get the username of the user login
  String contextStr = ADFWorklistBeanUtil.getWorklistContextId ();
  wfSvcClient = WorkflowService.getWorkflowServiceClient ();
  queryService = wfSvcClient.getTaskQueryService ();
  wfContext = queryService.getWorkflowContext (contextStr);
  userId = wfContext.getUser ();

  Returns the user name;
  }

• call method before managed Bean support page

  Hi guys,.

  My Version of Jdev is 12 c. I want to call a method of bean managed before my Page load. I did an EnableDisableMethod() method in my managed Bean that is my default activity in my taskflow. This method is only how to turn off to some of my Page buttons. I use * in my control flow so that my page will be called each time after the execution of my method by default. But what my result will be fixed for my activity method. Also what is the use of the result sets.

  <-l' id = 'enableDisable' method call >

  < method > #{pageFlowScope.bgBean.enableDisable} < / method >

  < result >

  < / results >

  < / method >

  Also when I run that application.page is empty but in newspaper that comes

  < 23 June 2014 12:41:30 IST > < WARNING > < oracle.adfinternal.controller.metadata.model.xml.PageFlowXmlImpl > < BEA-000000 > < ADFc: /WEB-INF/bGMstTF.xml #bGMstTF: >

  When I'm debugging its my default front method call load.but page does not redirect to my page. I think that the problem with my key component.before page load it does not know my button

  mainBtnAdd.setDisabled (true);  It is here, I think what he does ' t know button until pageLoad.mainBtnAdd is null in debug mode.

  Thank you

  Raul

  Oh and Yes your button is known that once the page is rendered. To solve your problem you add to the bean (Boolean or string) which then reference you via el of the property of button on the properties page. In method you you set just the properties of the bean.

• How to find the JSFF name in managed bean

  Hi gurus,

  I'm new in the adf and the use of 11.1.2.3. I'm looking for the name of page jsff managed bean.  For example, if I have abc.jsf contains a fragment of xyz.jsff. I want when I click on the button in the jsff page, a pop shows me the name is xyz.jsff.

  Thank you

  Hello

  to get the page name, FacesContext.getCurrentInstance () .getViewRoot () .getViewId () (return abc.jsf). If you expose the page through a region of the ADF fragment, then the call is

  ControllerContext.getInstance () .getCurrentViewPort () .getViewId () (returns xyz if the activity view has the same name as the file xyz.jsff Physics)

  In BookstoreBean.java, the purpose of the basket is not defined anywhere. How can the add method call add on the bean wagon without declaring the purpose of the basket. Is it because of the context and dependency injection?

  Elya wrote:

  I guess you mean it is not initialized with new anywhere. If the basket variable was not defined anywhere, you will get a compilation error.

  Is it because of the context and dependency injection?

  See where the cart variable is defined.
