Dynamic class in custom class reference

• Passing an object of the UiApplication class reference

  Hi all

  I am very new to the development of BB and have struggled for hours on something that I think should be very simple. What I have, this is the main class that extends UiApplication and a second class that implements Runnable. From a method in the UiApplication class, I create an instance of the Runnable class. After that, I call a method to start from this class and pass an object originally from the UiApplication class reference - so that I can call a method, once completed the processing of the Runnable class.

  The problem I have, is that once past the object through a call to method reference, the reference instantly cancels and causes a NullPointer exception when trying to call a method in the original class. The structure is as below, but with all the surrounding code subscribed:

  public class MainApp extends UiApplication {
  
      MainApp _MainApp;
      OtherClass _OtherClass;
  
      public static void main(String[] args) {
      MainApp _MainApp = new MainApp();
      _MainApp.enterEventDispatcher();
      }
  
      private void createOtherClass() {
          _OtherClass = new OtherClass();
          _OtherClass.someMethod(_MainApp);
      }
  
      public void response() {
          // code here
      }
  }
  
  public class OtherClass implements Runnable {
  
      MainApp _MainApp;
  
      public void someMethod(MainApp MainAppRef) {
          _MainApp = MainAppRef;
          // _MainApp object reference is null here
  
          new Thread(this).run();
      }
  
      public void run() {
          // stuff here
          // once done, call a different method
          sendDetailsBack();
      }
  
      public void sendDetailsBack() {
          _MainApp.response(); // causes a NullPointerException
      }
  }
  

  I rewrote this to only show the code at the source of the problem. I don't quite understand why the object reference is not passed correctly - I have tried many other ways to call back to the UiApplication function, including static calls.

  Any help on how I do it is very appreciated!

  I suspect that your problem is here:

  MainApp _MainApp = new MainApp();

  I think you meant just

  _MainApp = new MainApp();

• Dynamic class

  With dynamic Classes you can add properties at run time. But the same thing can be done with no dynamic classes by using the prototype property. For example I have a person class whose code is as follows:
  
  Class person {}
  private var: identification number;
  function Person() {}
  ID = 007;
  }
  }
  
  This class is now used in a fla file and create two instances
  
  var xx:Person = new Person()
  var yy:Person = new Person()
  
  trace (XX.__name) //undefined
  trace (yy.__name) //undefined
  
  Person.prototype.__name = "myPersonClass"
  
  trace (XX.__name) //myPersonClass
  trace (yy.__name) //myPersonClass
  
  If this is true then what is the difference between dynamic and not dynamic coz of classes using the prototype property, we can convert each class in the dynamic class.

  with a dynamic class, you can assign distinct __name properties for each instance.

  what you did was to extend the Person class, so it has a new property. If the Person class was final, you wouldn't be able to do. Otherwise, you can.

• Is it possible to remove a dynamic class properties?

  I have a dynamic ActionScript class that allows you to send parameters to a Web service. Some of these settings are still present, so that they are public properties of the class:
  
  package
  {
  [Bindable]
  public class dynamic WebServiceCriteria
  {
  public var property1:int;
  
  public var property2:String;
  
  public var property3:String;
  
  public var property4:String;
  }
  }
  
  But, I also add properties during execution that can change over time:
  
  criteria.runTimeProperty = "1";
  
  I'm not very familiar with the use of dynamic classes, so I was wondering if it is possible to 'remove' the new property. Let's say that the next time I call the Web service, I don't want the property sent - not even not as a null value. How can I remove it from the instance of the class without creating a new instance every time?
  

  Hello

  Please try to remove criteria.runTimeProperty. You can find more information about the operator delete the address below.

• AS3 - Dynamic class names with * new * operator

  I use AcrtionScript 3 and Adobe Flash 9 Public Alpha.
  
  I have 50 clips in the library that use the binding to set the class name: Img1, Img2, Img3,..., Img50.
  I have a parent named RandImg class. I want the constructor of RandImg select one of the 50 film clips from the library randomly and display it. I could get this to work by generating a random number and then writes a statement to switch really huge to associate each random number to its name of library Movie Clip respective class, but I'd rather do it with a name of variable dynamic/class based on the random number, such as:
  
  var nImgChoice:Number = Math.floor (Math.random () * 50) + 1;
  var mcImg:MovieClip = new ["Img" + String (nImgChoice)] (of).
  addChild (mcImg);
  
  Note that this has been possible in AS 2 as follows:
  
  this.attachMovie ("Img" + String (nImgChoice), "mcImg", this.getNextHighestDepth ());
  
  Suggestions?
  Thank you

  I hope that's what you wanted. I found useful. Alternatively, you can download a local copy if you want - although I don't see the need unless you have a completely free figure working environment and can work disconnected from the internet.

  See you soon.

• Class CSS SPACES custom skin reference? css styles do what?

  I create look custom for spaces using the custom project to extend the spaces. I'm not able to find what css class names are mapped to the elements of a page in the spaces. Inspect the code does not help because the css class names appear to be generated automatically and no names not really for all names in the example "myskin" or any other person I saw.
  
  Does anyone know a reference that shows which classes correspond to what in spaces?

  http://www.Oracle.com/technology/products/jdev/htdocs/partners/AddIns/Exchange/JSF/doc/skin-selectors.html
  This is an overview of the selectors used in the ADF. In my view, webcenter spaces uses only these. You should be able to your Web space using these selectors of the skin.

• LVOOP: summon screws (data) class reference member. alternatives for "in place"?

  Hello

  I use the structures in place for calling members screws of classes whose instances are referenced by reference to value of data of LabVIEW (DVR):

  1. create the DVR of the instance of the class;

  2. the DVR to a square pass in reference reading of the entry structure;

  3. call the VI in the place in structure.

  Does anyone know of a shortcut that works without place - is understood, for example, via invoke nodes?

  Thank you

  Peter

  There is only a single shortcut - if the Member screws are configured to access property of node, then you can wire the DVR in the property node and it will automatically get the object of the RECORDER. For other methods there is currently. See here to see what think OR this - http://forums.ni.com/t5/LabVIEW-Idea-Exchange/Have-Dynamic-Dispatching-terminals-accept-Data-Value-r...

• Link between classes: reference error

  Hello

  I am yet to try to create a movie clip to a list of objects appear on the scene and ask the user to interact with them.

  It will be my class of loop of game called "LetterArray()".

  My main class is called 'BugGoopFSGame() '.

  After that I added the line of code below in my LetterArray(). in the class file, I get the below error message:

  Code is entered:

  private var lettersL1:Array = new Array (a, f, g, h, i, n, o, s, t);

  It comes to getting the error message:

  ReferenceError: Error #1069: property [object T] not found on S and there is no default value.

  at LetterArray()

  at BugGoopFSGame()

  I do not know the reference I use between the two files are not good. Can you please tell me what code I need to add and where.

  Thanks for your help!

• Help contains no description for instance through me class reference and dialog object via this

  Hi DIAdem,

  I have a tiara 2015 SP2 version.

  The Scipt VB has a possibility to refer to an instance of the current class by me. It is sometimes important and useful. It works in tiara. But it is not described in the help of DIAdem.

  Tiara provides a reference to the current object SOUTH via this. It is not described in the help too.

  Can you tell us why or you can add it to future versions of the help / DIAdem?

  Thank you.

  Hi Sasha_62

  You can use 'This' in the Calculationscript for the calculation, in the Barmanger and in the SOUTH Editor.

  You're right, 'This' and 'Me' is not or not very obvious described in the help of tiara and we will try to do better in the next version.

  Thanks for the suggestion.

• Dynamic class loader during execution

  Hello

  1 as far I understand J2ME does not support the loader class API, and so the only way to dynamically load a class when running is to call Class.forName (). Is this correct? Is there another way around this?

  2 suppose I created a valid class file (' 'file:///SDCard/MyFiles/myClassFile.class ') during execution, if this file is located under the root of the SDCard, how I can call Class.forName and pass the name of the class file I just created? (The problem is that Class.forName expects a full qualified class name in the form: a.b.c.MyClassFile, while the file is physically located on the SD card.)

  Thank you

  Forget the class files. RIM has its own format of distrition with cod. Do not rely on the normal route, the java classes are stored.

  There is no "application" folder, you cannot add the classes here. Sorry

• Workflow managed bean with dynamic class

  Hello

  I am trying to create an Adaptive workflow, which is generic and can be reused.  The problem I have is trying to define the bean managed support.  Ideally I'd like a different class of bean to be used in various circumstances, but with the same name.  I don't know what class to use until the output of the task is called.

  I can't use for EL do know

  <managed-bean id="__1">
    <managed-bean-name>RegionBacking</managed-bean-name>
    <managed-bean-class>${pageFlowScope.regionBackingClass}</managed-bean-class>
    <managed-bean-scope>pageFlow</managed-bean-scope>
  </managed-bean>
  

  (regionBackingClass is a java.lang.String parameter passed in the taskflow with the class path).

  At this point, I need to use different classes have the same method names in their breast, just different code in methods, but that could change in the future.

  Thank you.

  Hello

  use a model approach. The managed bean configured as managed bean is simply a wrapper and instantiated dynamically the class that you want to manage the logic. Thus, you can for example pass the class name as input argument for the workflow in the managed bean and admire you the name then create the instance of the class to send all requests to.

• Class reference?

  I can't figure out how to create a reference to a class, so I don't have to keep typing the class.staticvar.item

  So usually, I have this:

  DocClass.build_class.firstFunction ();

  I have in my right sub class would be able to tell;

  private var build_class: Class = Class (getDefinitionByName ("DocClass.build_class"));

  so, in all of the upper class I don't have to type the reference, build_class...

  What I am doing wrong?

  You can get the name of the class (a string) of any object using:

  getQualifiedClassName();

  You can convert a string class to a class using getDefinitionByName().

  put the two together, you can get a class to reference are the build_stage_class with:

  var C: Class = Class (getDefinitionByName (getQualifiedClassName (build_stage_class));

• Document class reference

  This might be difficult for me to explain but here:
  
  I have a textField in frame 1 of a swf file. This swf has a document class. When I compile the swf I can change the text in the textfield easily with textField.appendText (text);
  
  However, when I compile a second swf that references this document class textField gives me an error on compile because it does not exist in the document class of the swf file that it is. How can I fix that? When I compile I get a 1120:Access error of undefined denied property. If I try to set the textField object in my class of document as private var textField; I get a confilct with the internal namespace...
  
  2 SWF has no idea SWF 1 has no idea SWF 1 has a textField in its timeline when is compiled.
  
  Is there a way around this or do I have to create the textField in my document class? There must be a way to mix sprites on a timeline and sprites in the document class.
  
  
  
  

  You must do two things to compile.

  1. in settings of publication-> uncheck the BOX settings ActionScript automatically declare it stage instances area.
  2 declare your text as public field: public var textField:TextField;

• Dynamic text with custom scrollbar

  Hello
  
  I am adopting oriented programming OBJECT Scrollbar 2 of Lee Bremelow to load external text. So far without success. This tutorial uses three classes. There is in the FLA scrollbox movieclip, within which are the dynamic text field (txtField) and the custom scroll bar (consisting of two elements: the thumb and track).
  If I copy some text in the text field, everything works. If the load external text in the text field, text is loaded but it doesn't scroll.
  Here are the codes of all the classes:

  Ok. Solved. Use this code to load the text in one place:
