• Access the ArrayCollection class MXML ActionScript collection?

  I have a MXML file that has a collection for my tree component arraycollection. I am overriding the updateDisplayList function to add lines to all of my nodes in the tree... However, I can't seem to understand how to access this ArrayCollection collection of inside the actionscript class?
  
  I tried the methods used to pass variables between two MXML files (like a popup window - which I've used in the past and it works very well).
  
  My actionscript class code is almost identical to this example here:
  
  http://www.iepl.NET/treeControlSample/treeControlSample.html
  
  In the example above, the data is static, but sometimes my data's going to change and I need to access the set dataProvider (collection ArrayCollection) in order to make the lines work well... This has been very frustrating for me! :)
  
  If someone knows a better way to reach gettign lines for brothers and sisters in a tree... Please let me know!
  
  Any help would be super duper awesome!

  I found the solution to this. My problem was similar to cheftimo was seen in this post:

  http://www.Adobe.com/cfusion/webforums/Forum/MessageView.cfm?forumid=60&CATID=585&ThreadId = 1367784 & enterthread = y

  The answer is to import the component you are trying to access the variable from and then call using mx.core.Application ' Application.application.'

• How to access the inner class fields in refleciton?

  I have:
  

  class Outer {

  I use reflection to get the Outer.field field and recognize that it is a reference to the inner class. What should I do to get the inner.field (or something that looks remotely like this at Inner.field)?

  Well, precedent is too messy for me even follow my example. I've simplified it, and I think I found where my error was. I suspect that you were doing a similar error:

  package scratch;
  
  import java.lang.reflect.Field;
  
  public class Scratch {
  
    public static void main(String[] args) throws Exception {
      new Scratch().go();

        System.out.println ("field.getClass().isMemberClass() (" + fc.getName() +" isMemberClass()) : " + fc.isMemberClass ());
        System.out.println ("field.getClass().getDeclaringClass() (" + fc.getName() + "'s declaring class) : " + fc.getDeclaringClass ());
  
        System.out.println ();

    }
  
    Inner1 i1;
  }

  field's class (field.getType()) : scratch.Outer1$Inner1
  field.getType().isMemberClass() (scratch.Outer1$Inner1 isMemberClass()) : true
  field.getType(). getDeclaringClass() (scratch.Outer1$Inner1's declaring class) : class scratch.Outer1
  
  field.getClass()) : java.lang.reflect.Field
  field.getClass().isMemberClass() (java.lang.reflect.Field isMemberClass()) : false
  field.getClass().getDeclaringClass() (java.lang.reflect.Field's declaring class) : null
  
  Note the difference between Field.getClass() (class java.lang.reflect.Field) and Field.getType() (class scratch.Outer1$Inner1)
  

  field.getClass () does NOT get the class of the field. It get the class of the field object that points to the field reference variable, which is always java.lang.reflect.Field. To get the class of the field, use field.getType ().

  Do you see the difference?

• Access the value of a variable assigned to CompositionReady?

  I created a variable called counter inside the 'scene' in the "CompositionReady" using the following code.

  var counter = 0;

  How to get or write the value of this variable

  through a 'trigger '?

  Remove the var on the counter.

  Just so put this in compositionReady

  counter = 0;

  Then you can just call him in a trigger as

  Alert (Counter);

  or

  counter + 1;

  or as if (counter == 1) {}

  }

  or whatever.

  I hope this helps.

• Change the value of "int" one within the arraylist class instance.

  It's my program...

  Well, nothing of this code will compile, but if you corrected the errors, and that was the case, you can replace it with

  hello.get(0).a = 123;
  

  But what you should really do is read all the tutorials you can find.

• To access the Java class control data

  Hi all
  
  I created a simple App Module for the employees table. The Datacontrol is created with that.
  
  I created a taskflow with default activity as methodCall (linked to a range of Pageflow ManagedBean method) which redirects to View1.jsff.
  
  In View1.jsff, I used the EmployyeeDatacontrol to create an unalterable form with just the navigation controls.
  
  In my method by default, I have no specific code...
  
  When I run the present my app works and I can display employee records and then go back.
  
  Now, in my method of the managed Bean, I'm trying to get the DCBindingContainer (IE DCBindingContainer is null)
  
  Now, the problem occurs, it always gives me NullPointerException when I do dcBindings.get("EmployeesView1Iterator"); Here is the code fragment.
  
  DCBindingContainer dcBindings = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();
  
  oracle.jbo.uicli.binding.JUIteratorBinding = employeesView1Iterator
  + (Oracle.jbo.uicli.Binding.JUIteratorBinding) dcBindings.get ("EmployeesView1Iterator"); +.
  
  I also tried creating the my ManagedBean Datacontrol and use it for the methodCall, always in the method I get NullPointerException (IE DCBindingContainer is null)

  I created a taskflow with default activity as methodCall (linked to a range of Pageflow ManagedBean method) which redirects to View1.jsff.

  You can not handle to BindingContainer in a before method call the page from your page has loaded not yet who has the necessary links.

  Maybe try (Gets the handle of the DataBindings.cpx AM) If you need a handful of the AM before calling method...

  BindingContext bindingContext = BindingContext.getCurrent();
  DCDataControl dc = bindingContext.findDataControl("name_of_application_module in dataBindings.ctx");
  AppModuleImpl appM = (AppModuleImpl)dc.getDataProvider();
  

• The abstract class constructor

  Hello
  
  I can write a constructor for the abstract class, but I can't create the object. So, what's the point of this?

  Hello

  Abstract class can have instance variables. To initialize the instance variables of the class super (abstract class) of upper class, we use the constructor in the upper class (abstract class).

  Super() can be used here. For example,.

  public abstract class ClassA {
       int a;
       ClassA(int x) {
            a = x;
       }
  }
  
  public class ClassB extends ClassA {
       int b;
       ClassB(int x, int y) {
            super(x);
            b =y;
       }
  }

• BI SampleAppFiles Server cannot access the correct file

  Hello experts,

  Part of my project is creation of KPIs for my clients. Before doing all this, I'm trying to create a KPI sample and see if it works well.   It is using 11g (1.1.7).

  Here's the problem: I created the sample KPI without problem; However, when I try to open the report I get an error that

  State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error occurred. [nQSError: 43113] The message returned by OBIS.

  The path is correct, except instead (E:\), it should be (C:\).  Does anyone know how to change this? Help, please.

  I don't have a 'E' drive in my system. This forum works on windows

  Help, please

  Hello

  In the sample OBIEE, you have a variable called BI_EE_HOME with this path

  To change this, open your SPR (online mode) and then change repository variable BI_EE_HOME

  

  We call this variable in your connection pool (you can change this path directly on the connection pool too)

• ClassCastException in the custom class loader

  I created a custom class Leon.

  My requirement is the class MyObject needs to be loaded by my client class loader. If you say that let the superclass (MyObjectSuperClass) be in the class path and let the class system charge charger, then usually it be a problem

  No, it's exactly what you want.

  MyObject loaded by the custom class loader, its super class loaded by the system class loader, I will be able to cast then.

  Yes, you will be able to cast to the upper class, then.

  It is not similar to the statement "MyObject loaded by the class loader and custom class system are different and we cannot throw.

  No, it isn't. your confusion is due to the fact that you don't seem to understand that you can have a class hierarchy that spans the Chargers of classes. This should be obvious because each object hierarchy extends eventually object, which is always in the system class loader. Therefore, you can always convert any instance of any class loader "Object". in the same way, you can have MyObjectClass in your chargers personalized classes and MyObjectSuperClass in the system class loader. You can instantiate an instance of MyObjectClass to aid reflection on your custom class loaders and assign it to a reference of the type MyObjectSuperClass. This is how pretty much any plugin system is implemented (the API is in the 'main' class loader and the implementation is in a nested class or custom ClassLoader).

• How to access the BPM 11 g load useful or process varibles in the workflow of ADF

  I'm trying to view/edit the data in a user interface that is linked to a database by using a foreign key, requestId. The foreign key comes from a BPM process where it is spent in the workflow, a human task. The foreign key comes process variables or values of payload. I know that I can simply load the payload in BPM with the data in the tables, but I'm looking for a better solution use the ADF business components to view and edit data directly in the user interface.
  
  The BPM process uses a web service to start the process. Web services takes a primary key as a parameter to reference a column in the database table. The data is pre-filled with content and a primary key reference. The first activity is an activity of the user. I want the workflow behind the user activity to accept this primary key and use to locate the line in the database, so related views of the database delimited ADF business components can work to present the data in the user interface.
  
  I tried two approaches to the problem. The first uses the setCurrentRowWithKeyValue operation. The other changes the SQL where clause, used by the ADFbc iterator only returns one row for the given requestId. Both of these approaches fail to work because I don't know how to access the load BPM or variable data entering the workflow. Here is the piece of code that I used to try to define the row using the value of setCurrentRowWithKey:
  
  public String setRequestId() {}
  
  FacesContext context = FacesContext.getCurrentInstance ();
  Object requestObj = context.getApplication () .evaluateExpressionGet)
  context, "#{bindings."(, Number.class) RequestId.inputValue "};
  If (requestObj is nothing)
  Returns a null value.
  RequestId number;
  requestId = (number) requestObj;
  
  ITR DCIteratorBinding = (DCIteratorBinding)
  
  getBindings () .get ("PatfRequestHdrView1");
  
  itr.setCurrentRowWithKeyValue (requestId.toString ());
  
  Returns a null value.
  
  I didn't get very far with the second approach, change SQL where clause, because I do not know Groovy. I think I need something like:
  
  adf.object.viewObj.RequestId. but it is not a viewObject associated with BPM data, so I don't know that this particular expression will not work.
  
  Any help you can give me is greatly appreciated.
  
  Kind regards
  Mark

  Try this code in your method:

  FacesContext context = FacesContext.getCurrentInstance ();
  String ctx = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistContext}", String.class);
  String tskId = (String) context.getApplication () .evaluateExpressionGet (context, "#{pageFlowScope.bpmWorklistTaskId}", String.class);
  IWorkflowServiceClient workflowSvcClient = WorkflowService.getWorkflowServiceClient ();
  ITaskQueryService wfQueryService = workflowSvcClient.getTaskQueryService ();
  IWorkflowContext wfContext = wfQueryService.getWorkflowContext (ctx);
  Task myTask = wfQueryService.getTaskDetailsById (wfContext, tskId);
  XMLElement xmlPayload = (XMLElement) myTask.getPayloadAsElement ();
  get the payload as a string simple, useful for debugging
  java.io.StringWriter writer = new java.io.StringWriter ();
  xmlPayload.print (writer);
  String payloadAsString = writer.toString ();
  extract payload values: use methods in Oracle XDK

  .t-PageBody--login .t-Bodyis a descendant selector. It matches any element with a class attribute that contains a t-Body value having an element ancestor with a class attribute that contains a t-PageBody--login value. There is no concept of 'main' class or 'slot' in CSS. The required selector is likely to have been determined on the supplement page using a web Inspector.

  It is advisable to take some tutorials to get at least a basic understanding of web technologies when you work with APEX.

  You can only put assignments or expressions inside the methods, of the builders or the initializors class, or when you declare a variable.
  It has nothing to the child which stretches from Parent.

  class Parent {
      int a = 1;
  
      { a = 1; }
  
      public Parent() {
          a = 1;
      }
  
     public void method() {

• Instance of MovieClip Access on stage in the other classes

  Hello.

  I have the instance of movieclip on the stage.  Instance name qwe of the shiptype.

  I want to access it in other classes EnemyShip.as.

  I tried this.

  MovieClip (this.parent) .getChildByName ("qwe")

  but I got

  TypeError: Error #1034: Type coercion failed: cannot convert flash.display::Stage@26d03041 to flash.display.MovieClip.

  I don't have any class of document.

  Publish settings controlled on automatically declare stage instances.

  y at - it access qwe in EnemyShip.as anyway?

  And here is the link to my flash project:

  http://www.mediafire.com/?kf6uiunys20cyzz

  If the ship is created the instance of the enemy, you can pass the instance of the ship in the object of the enemy when you create it using something like...

  var enemyship: EnemyShip = new EnemyShip (this);

  and in your EnemyShip.as receive you and assign it to a variable, so that you can reference it beyond the EnemyShip function

  public var _qwe:MovieClip;

  public void EnemyShip(ship:MovieClip)

  {

  _qwe = ship;
