  Hi Samson,.

  Here are the groovy expression to access the value of the sessionscope:

  adf.context.sessionScope.role
  

  But, as the said John instead to access the session of the model can be a method of model (whether in AMImpl or voImpl) who takes the role as a parameter value and sets the value of the variable binding of the vo, then call this AM from the bean method passing the role value by getting the scope of the session.

• to access the variables in a page in another page qml

  Hey gang,

  I've been watching some of the other problems autour to access the variables from one page on another page qml qml, and I can't get this to work.

  I have a page, main.qml with a NavigationPane.  The NavPane has a Page and some containers.

  I have a property defined in the NavigationPane like this:

  NavigationPane {
      id: mainNav
      backButtonsVisible: true
      property int customInt: 2
  
      onCustomInt: {
          console.log("  -------------> App: customInt");
      }
  

  I have a ComponentDefinition for next page, called SettingsPage.qml.  In the settings, I have two drop-down lists and a slider.

  Page {
      actionBarAutoHideBehavior: ActionBarAutoHideBehavior.HideOnScroll
      id: pgSettings
  
      ScrollView {
          id: pageScroller
          scrollViewProperties.initialScalingMethod: ScalingMethod.AspectFit

  I look forward to the the statement will change the level property NavPane, called customInt, but it doesn't.

  the output of the console shows that the ' App: Option 1 selector "gets selected in the dropdown list selected index changes, but the onCustomInt() funtion slot never gets called.

  I tried "mainNav.customInt = X" too, but the parameters cannot solve the mainNav.  I get "unknown symbol 'mainNav'" error with alittle bulb.

  what I am doing wrong?

  When you call the second page, SettingsPage.qml, set it as an object.

  Don't do the following:

  attachedObjects: [
  
      ComponentDefinition {
          id: settingsPageDefinition
          source: "SettingsPage.qml"
      }
  ]
  

  Follow these steps:

  attachedObjects: [
      // Definition of the second Page, used to dynamically create the Page above.
      ComponentDefinition {
          id: settingsPageDefinition
          Settingspage{
  
          }
      }
  ]
  

  Then the second page main navigation page in the IDE.  I had the same problem with a multi-page application, I created.

• How to access the variable in the child video clip

  I have a flash file that uses php to manipulate a database and returns a variable (data_xml) to document data in XML from the database. In this case, as well as others within the parent company. Now, I have a child movieclip that shows analyzed data, but I'm unable to access the variable from the child movieclip. The code associated with this is:

  var myXML:XML = new XML();

  You've declared the variable twice. Variable can be declared only once in any scope. So, your code should be:

  You're confusing SQL * more variable substitution (those with '&') and bind variables.

  Replace the "& username" with: username as shown below:

• To access the variables from a movieclip timeline

  Hey everybody!

  Normally, I use MovieClip (this.parent) to access a variable that is outside the movieclip I am writing code in. However, this does not work in both functions.

  For example:

  function editMainText (e:Event) {
       MovieClip(this.parent).headline.text = "Hello"
  }
  

  works.

  but

  function editMainText (e:Event) {
       function editText (e:Event){
            MovieClip(this.parent).headline.text = "Hello"
       }
       editText(null);
  }
  

  does not work

  There is probably some small errors in my code, but I need mainly to learn how to change MovieClip (this.parent) to work within the second function.

  Thank you!

  John

  does not work.

  In most all cases I've seen, nested functions will stand on their own

  function () {} editText
  MovieClip (this.parent).headline.text = 'Hello '.
  }

  function editMainText (e: Event) {}
  editText();
  }

  This is the way of declaring bind variables in SQL * more.

  In a PL/SQL block, you do not use bind variables like SQL * more. You just use normal variables. The PL/SQL engine is smart and sends SQL statements to the SQL engine containing all PL/SQL variables converted to bind variables. If it works transparent in PL/SQL and you don't have to do something more.

• How to access the variable JoinColumn directly in an entity.

  E1. Department = d;
  
  Is there a way to uncomment Employee.emp_department_id and insert data about employees using PT. 1 ???

  The correct method is to define the ManyToOne and set it to the appropriate Department. You can use find() or getReference() to get the service object with the ID.

  If you want to have a base for both Id mapping, then you must use the same column name.

  @JoinColumn (name = "emp_department_id")

  should be,

  @JoinColumn (name = "EMP_DEPARTMENT_ID")

  But since you have two mappings for the same column, you must set one of them write,

  @JoinColumn (name = "EMP_DEPARTMENT_ID", insertable = false, updatable = false)

  Or you could remove the ManyToOne and have just the base.

• ADF where can I set the variable binding VO?

  Public Sub beforePhase (PhaseEvent phaseEvent) throws SQLException {}

  If (phaseEvent.getPhaseId () == PhaseId.RENDER_RESPONSE) {}

  Here the implicit conversion does not work, and '3.4' is considered a stgring rather 2 separate values. I have to have to use bind variable and do not want to use dbms_sql. Is it possible, '3,4' is taken as 2-digit values, rather a string value helps Pl, thanks.

  You cannot use list as a bind variable. Use:

    2  p_id IN varchar2)
    3  is
    4  sql_str varchar2(100) := 'SELECT * FROM tab WHERE tab.X IN (' || p_id || ')';

    3      as table of number
    4  /
  
  Type created.

• How to get the value of the variable using EL sessionScope

  Hi all
  
  I'm working on Jdeveloper 11.1.1.5.
  
  Just for example, say:-J' have a button and a text box. The button, I got this method: -.
  
  public String cb2_action() {}
  jsfUtils.storeOnSession ("DELETE", "Y"); *
  Returns a null value.
  }
  
  Now, I have a text box where I need to check if the DELETE Variable has value 'Y '. If it has the value 'Y' will then render the text box on the other not.
  
  < af:inputText label = "Label 1" id = "it2' partialTriggers = 'cb2.
  rendered = "#{sessionScope.Delete eq 'Y'}" / >
  
  But when I click on the button, I'm not able to see the text box. Means that the Expression is not correct.
  
  Please suggest!
  
  Kind regards
  Shah

  Have you tried to use the visible property instead of the rendered property?
