  ADF7,
  I'm not sure that understand what you're up to.
  For as far as I understand you want to get the value of display rather than the index
  I use this code

      public void StatusChangedListener(ValueChangeEvent valueChangeEvent)
      {
          BindingContext lBindingContext = BindingContext.getCurrent();
          BindingContainer lBindingContainer = lBindingContext.getCurrentBindingsEntry();
          JUCtrlListBinding list = (JUCtrlListBinding) lBindingContainer.get("Status");
          int newindex = (Integer) valueChangeEvent.getNewValue();
          Object row = list.getDisplayData(); // Wichtig um die liste zu laden!!!!
          Row lFromList = (Row) list.getValueFromList(newindex);
          Object lAttribute = lFromList.getAttribute("Value");
          String newVal = (String) lAttribute;
      }

• How to get the value of inputText

  Hello
  I am a beginner in oracle adf, I want to know how can I get the input for the InputText component value
  I use JDeveloper 11 g version (1.2.3.0)
  ----------------
  Thank you

  Hello

  There are many ways: -.

  1. in your managed Bean
  private String Ivalue;

  Create the getter and setter.

  Select the text entry and in the value property, select the Ivalue created in the managed bean.

  Now if you want to get the value of the TextBox when the button is clicked, you can probably get the value using this. IValue.

  2. Select the text of the entry, in the property of the set value like this, #{viewScope.IValue}
  And when the click on the button, you can get the value using AdfFacesContext.getViewScope.get ("IValue");

  I hope that helps!

  Kind regards

• How to get the value of the textInput component to perform the calculation?

  

  I need some help here... I'm trying to get the value from the user input to the TextInput component that is the age, size and weight to calculate the bmr and display the result in member("result").text.

  How am I suppose to pass the integer in order for me to perform the calculation? If you'd be grateful if someone can help me with this, thanks!

  Here's the formula:

  The equation of Harris Benedict BMR estimates:

  For women: (9.56 x w) + (1.85 x h) - (4.68 x a) + 655

  For men: (13.75 x w) + (5 x h) - (6.76 x a) + 66

  My mistake. You can only re-branded a string to the text property of a text member. Just need to convert the value to a string using the string function.  Use this

  Member ("result"). Text = string ((13.75 * value (member("weightText").text)) + (5 * value (member("heightText").text))-(6.76 * value (member("ageText").text)) + 66)

• ([JDev12c, ADF] 1) how to get the value of a field of the line currently selected in question 2) af:table: flowScope

  Hallo,

  How can I get the value of a field in the row that is currently selected in an af:table?

  I need to pass this value to a setCurrentRowWithKeyValue who took the record to display in another (by a button) called page:

  Limited workflow

  Page1 - goToPage2-> setCurrentRowWithKeyValue-> PAGE2

  I defined a managed bean flowScope for the workflow in which I created the variable 'CodeToSetPage2Row '.

  I will store the value of the field for the selected line in this variable so that I can move on to the setCurrentRowWithKeyValue.

  Could be this method OK? Ore is there any good practice to achieve this goal?

  The managed bean flowScope used to go to the stubborn task may take some values from the outside?

  The workflow defined will be executed in a dynamic region.

  Thank you

  Federico

  Federico, you cannot use a flow variable scope for this page. The region has no access to the bean. You must use a workflow for this parameter.

  To get an attribute of the currently selected line you make slide data vo of control on the page attribute. This will create a link attribute for this attribute. Once this link exists, switch to source mode and remove the component that you do not want.

  The framework passes the value of the current row in this affair of the attribute (table should be in single selection mode).

  Click on the button, you switch the binding of the attribute for the setting of task flow using a setPropertyListener.

  In the workflow, you call the setCurrentRowWithKeyValue with the parameter of workflow as the default activity.

• How to get the value on a model that is defined in the java code in email

  Hello

  I created a custom code and send email as well to custom component. I can send emails using the method:

  InternetFunctions.sendMailTo (EmailID, EmailTemplate, subject, cxt);

  But my problem is that I have to get a value in the model of "EmailTemplate" which are defined from java code. but I don't know how to get the value.

  I will highlight in the java code by using this code: binder.putLocal ("ErrorApproveRejectMsg", massegeBody);

  I'm trying to enhance the model using the code below, but not able to get.

  1 < $exec getValue ("#active", "ErrorApproveRejectMsg") $ >

  2 < $exec getValue ("#active", ErrorApproveRejectMsg) $ >

  3 < getValue ("ErrorApproveRejectMsg") $exec $ >

  4 < $exec getValue (ErrorApproveRejectMsg) $ >

  5 < getValue ("#local", ErrorApproveRejectMsg) $exec $ >

  6 < getValue ("#local", "ErrorApproveRejectMsg") $exec $ >

  7 < $ErrorApproveRejectMsg$ >

  8 < $exec ErrorApproveRejectMsg$ >

  Assuming that cxt will be your Service or execution context object

  You can do something like this

  DB. PutLocal ("ErrorApproveRejectMsg", "Error");

  cxt.setCachedObject ("DataBinder", db);

  PageMerger h = new PageMerger (db, cxt);

  cxt.setCachedObject ("PageMerger", h);

  InternetFunctions.sendMailTo (usersEmail, emailTemplate, emailSubject, cxt);

  where db is current databinder object, and you can put any variable custom in the workbook by using the putLocal method.

  Thank you

• How to get the value of the outputtext in javascript and send it to backing bean

  Hi Experts ADF,

  JDev Version 11.1.1.7.0

  I have the following: the value of the outputtext must be treated in javascript and the serverlistener method has the same value. I founded this value returns a string that wshould see the mouseover NIJ.

  Help, please. Thanks in advance.

  < af:column sortProperty = "#{bindings." OrderProposalReadClient.hints.exceptions.name}.

  filterable = "true" sortable = "true".

  headerText = "#{suiviewBundle.EXCEPTIONS} '"

  AdfCustomEvent.queue ();

  Returns true;

  }

  < / af:resource >

  BackingBean

  public String handleServerEvent(EC ClientEvent)

  {

  Please let me know how to get the value that javascript code sends here.

  Let's say javascript sends the value of outputtext as "001".

  So, I have to check "001" in my list and return a value that appears on mouseover.

  }

  Kind regards
  Roy

  Hello, Roy.

  To use the value on another component of the user interface, I shows an example:

  -code of the page

  shortDesc = "shortDesc" >

  method = "customJsFunction" / >

  
  

  -the javascript code

  var customJsFunction = function (event)

  {

  var exceptiondata = event.getSource ().findComponent("ot32").getValue ();

  AdfCustomEvent.queue (event.getSource (),

  "mycustomserverEvent,"

  {param1:exceptiondata},

  (true);

  Returns true;

  }

  -OutputTextCase11.java

  public void handleServerEvent (EC ClientEvent)

  {

  String param = (String) ce.getParameters () .get ("param1");

  RichOutputText outputText = (RichOutputText) ce.getComponent () .findComponent ("ot1");

  outputText.setShortDesc (param);

  outputText.setValue (param);

  AdfFacesContext.getCurrentInstance () .addPartialTarget (outputText);

  }

• How to get the value of messageStyledText that is present in the other RN

  Hello
  
  I have xxcompscore messageStyledText in the region 1 (separate controller) and xxobjscore messageStyledText in the region.2 (separate controller).
  
  The two values are doubles.
  
  My requirement is to get that value from another region (layout) and adds that the values and display in the RN.
  
  How to do this, I tried a lot but I get error NullPointerException.

  HI San,

  According to my understanding, you have the following requirement.

  xxcompscore messageStyledText in the region1 (separate controller) - Say controller is XxxRN1CO
  xxobjscore messageStyledText in region.2 (separate controller). -The controller is XxxRN2CO
  Page Layout RN - Say controller is XxxPageLayoutRNCO

  If you try to get the value of the region1 - PR Noire2 and display in Pagelayout cannot be achieved by the way you write the code...
  What follows is drawn sequence of the controller...
  1 XxxPageLayoutRNCO--> processRequest
  XxxRN1CO--> processRequest
  XxxRN2CO--> processRequest

  XxxRN2CO--> processFormRequest
  XxxRN1CO--> processFormRequest
  XxxPageLayoutRNCO--> processFormRequest

  So you can't get the session values configured in XxxRN1CO--> processRequest or XxxRN2CO--> processRequest in XxxPageLayoutRNCO--> processRequest.

  You need to take the following approach to get these values.

  -> If the underlying VO for the region1/region.2 is executed in PageLayout controller or controller of the region1
  then you can get the required values of the underlying attributes of your calculation VO do and set the value of TotalScoreText
  on the other
  If executed in the level controller VO region then you will need to run these vo also in pageLayout controller and
  get the values of the attributes of VO and do your math and set the value to TotalScoreText

  Let me know if you need assistance.

  Kind regards
  RAM
