Custom events never achieve listening feature

• Custom event listener callback fails

  Hello

  I have a mobile project Flex 4.6 and I created a custom event, I can see different tracks that the event is currently distributed as planned, but no matter what I do I cannot get a listener to the work that they just sit there and nothing ever happen, please take a look and tell me what might be wrong.

  Custom event:

  package classes.events

  {

  import flash.events.Event;

  SerializableAttribute public class cartLoaded extends Event

  {

  public static const = "cartLoadSuccess" CART_LOAD_SUCCESS:String

  public void cartLoaded (type: String, bubbles: Boolean = false, cancelable: Boolean = false)

  {

  trace ("event_dispatched");

  Super (type, bubbles, cancelable);

  }

  override public function clone (): event

  {

  trace ("event_cloned");

  return new cartLoaded (type, bubbles, cancelable);

  }

  }

  }

  The event is dispatched to a class, after a ResultEvent returned by a Web service call, so in the ResultEvent reminder I have:

  var cl: cartLoaded = new cartLoaded (cartLoaded.CART_LOAD_SUCCESS);

  e.currentTarget.dispatchEvent (cl);

  And I see "event_dispatched" in the console when my results come back. So, I know that the event is triggered. Now on the file of main Application in the ViewInit on a list, on a view that I add, I have almost tried this anywhere.

  lst_cart.addEventListener (cartLoaded.CART_LOAD_SUCCESS, LoadData);

  function loadData(e:cartLoaded):void

  {

  trace ("data set provider");

  }

  I never see "set the data provider, now I understand that the listener must be saved before the event is dispatched, and in my case, it certainly is:

  I have a vision (tried to addEventListener here in an initialization handler)

  the view contains a list with a custom converter (tried here)

  the itemrenderer contains a button (have tried here)

  the button calls a method in a class that raises a web service call (this is where the event to send)

  the web service call triggers a result event

  the result event is triggered my custom event

  Please help, because it is seriously holding me back, I have to be able to capture this event, and I've tried everything.

  Pauleta is true that there is a loss in the case of the chain, like the wrapper it cannot listen on the list because the list itself is not part of the hierarchy of the event.

  I think you can get around this in two ways.

  1. Have your Cart class extend the EventDispatcher class. If this is not possible at least implement IEventDispatcher interface and have a composite object that is the event dispatcher. Anyway, given the class cart is a form of an event dispatcher.
  2. Have your item converter listen directly to the event on the Cart class.
  3. Your event handler converters, to ship another event that spreads to the top of the display object hierarchy.

  Something like this:

  public class Cart extends EventDispatcher
  {
       public function doStuff() : void
       {
            ...
            dispatchEvent(...);
       }
  }
  
  OR if you can't extend it
  
  public class Cart implements IEventDispatcher
  {
       private var _eventDispatcher:EventDispatcher;
       //contains all the methods of the IEventDispatcher interface but uses a facade layer
       public function Cart()
       {
            _eventDispatcher = new EventDispatcher();
       }
  
       public function addEventListener(params...) : void
       {
            _eventDispatcher.addEventListener(params...);
       }
  
       public function doStuff() : void
       {
            ...
            _eventDispatcher.dispatchEvent(...);
       }
  }
  
  public class MyItemRenderer
  {
       public function buttonClick() : void
       {
            var cart:Cart = new Cart();
            cart.addEventListenerer(...);
            cart.doStuff();
       }
  
       public function doStuffEventListener(event:Event) : void
       {
            //Make sure the bubbles property is set to true
            dispatchEvent(event.clone());
       }
  }
  

  This should ensure that the event now on the queue from the list view... If she is probably not a good idea to constantly be adding some that this event listeners, it is probably better just to have a callback function and pass it to point converters to pass based on the cart process.

• Several components are listening to the same custom event?

  I tried to make the transition from Flash to Flex and I've been struggling with this one for the last two days. I used to do a lot of SEO _root.moviecontainer.mylable.text, but I'm trying to get the idea of demonstrations, dispatchevents, etc. down and get SEO for Flex to manage. The simple explanation of what I'm trying to do is to have a component triggers an event and either dynamic broadcast to all components that subscribes to this event (the number of components listen to will change during execution and so I don't want to directly refer to these objects). I would like to be able to generate other objects during execution and to associate them with this event dynamically. I tried to add an addListener (customEvent) to listen to the dispatchevent(), but I had no luck with this method until now. Raises the event, but I can't understand how to associate other components with it. I guess that having only three parts to it: the component that triggers the event, the event itself (custom) and the component that is listening for the event. And none of the components know anything of the any of the other components that exist. The trigger could be raising an event 3, 10, or 100, other components are listening, but he doesn't know how many elements are tuned, nor she cares & maybe even wait for one component which is capable of raising the event, he is listening the listening component, or there could be a total of 10 components capable of triggering this event. If you did it at the end of the present, thank you. This has been a headache for me, and I'd appreciate any help offered. Thank you.

  iTextArea is a brother of iButton and isn't in its parent chain, so it will not be a propagated event.

  Perhaps you could put a Manager in the Application that redistributes events and listen for them in iTextArea.

• post a custom event to trigger the listener

  Hi all:
  
  My project read resultset of a database table and a while loop I put the records in a cache one by one. I registered a listener with the cache, and when an insertion event occurs, the listener #entryInserted record the news record in a log file. Everything works very well.
  
  Now at the end of the while loop, I would like to post (send or fire) an event on measurement (including information like the total count) to the listener to say things, "that's all!" and the listener must react accordingly.
  
  Can we do with the APIs of consistency? If so, how?
  
  Thank you

• Problems with custom events

  I'm trying to figure out this problem I'm having with custom events, I've read all the documents and tutorials that I can find, and this bit still makes no sense.
  
  I have the following configuration:
  
  LoginForm: custom component (which is created as a popup via the PopupManager)
  ApplicationHeader: custom component (which is added to the MXML application)
  application: creates the LoginForm as a popup via the PopupManager, has ApplicationHeader defined in the MXML.
  
  When a user logs in the LoginForm dispatches an event customized, there are two defined listeners:
  
  1. in the application:
  
  private void showLoginForm(): void {}
  var loginForm:LoginForm = LoginForm (PopUpManager.createPopUp (this, LoginForm, true));
  loginForm.addEventListener (UserLoggedInEvent.USERLOGGEDINEVENT, userLoggedInHandler);
  }
  
  2. in the component custom of ApplicationHeader :
  
  private function init (): void {}
  parent.addEventListener (UserLoggedInEvent.USERLOGGEDINEVENT, userLoggedInHandler);
  }
  
  When the event is dispatched the request listener picks it up as expected, however the listener inside the custom component sees ever-even if the event is set to bubble.
  
  The only way I managed to get this working is to do the following in the application:
  
  private void userLoggedInHandler (event:UserLoggedInEvent.USERLOGGEDINEVENT): void {}
  // .. the event handling logic
  the return of the event
  dispatchEvent (event);
  }
  
  This makes no sense at all, what happens if I didn't want the application to handle the event itself. There is a line in the documentation of the event
  who says "You can only save a listener of events with an object if that object dispatches the event." who could explain it, but it is still absurd.
  
  Any help/tips/examples would be most useful as I am pulling my hair out here.

  Never mind, I just read this post ( http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=60&catid=585&threadid = 1257178 & highlight_key = y & keyword1 = custom % 20components) and I was pointed in the right direction - I had to add the metadata for the event to the application.

• What is the custom event that fires?

  Hello
  
  What is customized event triggered in the OPA.
  
  I heard that, at the time of the training online OPA in last week.

  A custom event is a way to write a rule that will send a signal. When executing time event listeners can be attached to the motor of the OPA, and a custom event can be used as a way to signal that something should happen.

  For Documentation on writing a raiseevent rule see rules of use to trigger external software applications in modeling of political Oracle Help.

  For Documentation on the event listeners, see events and event handlers and example: handle the events of modules with an inference event listener in Oracle policy Automation Developer Help.

• Custom events are not heard or sent successfully

  Hey guys, I did experiments with the writing of my first custom event.  So I have a MovieClip class in the library called "curtains."  He plays an animation and at the end of the animation, I have the code:

  Stop();

  dispatchEvent (new Event ("closed"));

  Now, I create an instance of this MC curtains in my class below.  The custom event is not detected.  Did I put the event listener in the wrong place?  What I've done wrong?

  package {}

  import flash.utils.Timer;

  import flash.events. *;

  import flash.display. *;

  SerializableAttribute public class TransitionTimer extends MovieClip {}

  var localTimer:Timer = new Timer (4000,1);

  curtains: curtains of var = new Curtains();

  public void TransitionTimer() {}

  localTimer.addEventListener (TimerEvent.TIMER_COMPLETE, playTransition, false, 0, true);

  addEventListener (Event.ADDED_TO_STAGE, addedHandler);

  }

  public void addedHandler(e:Event):void {}

  starts the timer which called Transition curtain

  localTimer.start ();

  Adds the event listener for the custom event 'closed' to frame 27 curtains MC.

  curtains.addEventListener ("closed", loadNextScreen);

  }

  public void playTransition(e:TimerEvent):void {}

  addChild (curtains);

  }

  public void loadNextScreen(e:Event):void {}

  trace ("loadNextScreen");

  curtains.gotoAndPlay ("open");

  }

  }

  }

  Thanks in advance for any help

  Add a track to your class TransitionTimer to confirm that it is used as the document class.

  Add a line to the last frame of your movieclip where your 'closed' event is dispatched.

  Copy and paste the instructions of tracing so that might not be obvious what is your problem.

• Variables that may be related to custom events Vs

  Greetings to all...

  I'm working on an application that is too great, so whenever we can, we create custom components and classes to organize the entire procedure as good as possible.

  Today, I was working on a login form that is also a custom component.

  So, this component has a remote object to get the user to the server if the connection is successful.

  This user must be sent to other components too and also in the main application that is the parent of the connection.

  I created a custom event that is shipped to the component if the connection is successful.

  My main application is to listen to this event in order to get the logged in user.

  It's a way to do it.

  The other way would be to make two user objects can be bound and whenever the user inside the element object is ready it would change too.

  Which do you think is the best approach for what I'm doing?

  In my opinion (since I read a looooot on memory leaks with objects that can be linked) the best approach is to work with objects that can be linked only when its necessary.

  Your opinion about this?

  Binding is not prohibited, as it is a valuable element of Flex, but sometimes when you use the binding, you end up elements of hard wiring in your application, which limits your ability to code reuse more easily.

• What is the point of having the function of the cloning in custom events?

  What is the point of having the function of the cloning in custom events? I do this, but never understood why lol

  The EventDispatcher call to clone the event when you return an event with dispatchEvent (event). It is also why you should implement it correctly (copy all properties), otherwise the listeners who handle the redispatched event will receive an event with incorrect values.

• Management of the custom event sent by loading SWF fails

  I loaded and SWF using SWFLoader. Not a component, but just a regular Flash AS3 SWF. I can access its properties and functions but when I listen to a custom, event distributes, I get the error:

  Error #1034: Type coercion failed: cannot convert com.subhumanmedia.classes::SoundCueEvent@911ad61 to com.subhumanmedia.classes.SoundCueEvent.

  Here's the event:
  package com.subhumanmedia.classes
  {
  import flash.events.Event;
  SerializableAttribute public class SoundCueEvent extends Event
  {
  public static const = "cueSound" CUE_SOUND:String
  
  private var soundCueObjectInstance:Object;
  
  public void SoundCueEvent (type: String, bubbles: Boolean, cancelable: Boolean, soundCueObject:Object)
  {
  parameter soundCueObject:
  soundCueObject.cueSoundURL is the string with the name of file to play
  soundCueObject.cueSoundStartTime is the number giving the millisecond offset to read from
  //
  Super (type, bubbles, cancelable);
  soundCueObjectInstance = soundCueObject;
  }
  public function get soundCueObject (): Object
  {
  Return soundCueObjectInstance;
  }
  override public function clone (): event
  {
  return new SoundCueEvent (type, bubbles, cancelable, soundCueObjectInstance);
  }
  }
  }

  Here is the statement in the loaded SWF, the event:
  dispatchEvent (new SoundCueEvent (SoundCueEvent.CUE_SOUND, true, false, soundCues [cueCounter]));

  
  soundCues is an attay soundCueObjects.

  Here is the definition of the listener in my main class:
  slide.slideGraphic.swfObject.content.addEventListener (SoundCueEvent.CUE_SOUND, cueSoundHandler);

  And here's the Manager:
  private void cueSoundHandler(e:SoundCueEvent):void
  {
  trace (e);
  }

  If I change the type of parameter of the event Manager, it does not take a mistake, but I can't yet ride a SoundCueEvent event in order to obtain tracking information.

  Now both the right loaded SWF and main class get the definition of the event from a compiled SWC, but I tried several other ways to do it without any better result.

  I don't know even what causes the error and am totally baffled by how to solve it. Can anyone help?

  It is equivalent to the problem of shared code described in the presentation of the modules on my blog.

• Custom events

  Hello

  I want to trigger an event to a class and listening to the other.  There are several examples on the net but I don't really understand them.  Can someone explain please how can I get the value of newTextInput in the lower class on the evolution and pick it up in another class.

            public function changeHandler(event:Event):void{
                 
            }
            
            //  Creates a text input 
            public function setText(label:String, type:String, id:String):void{
                 var newFormItem:FormItem = new FormItem;
                 var newTextInput:TextInput = new TextInput;
                                
                 newFormItem.label = label;
                 newTextInput.id = type;
                 newTextInput.text = id;
                 newTextInput.addEventListener(Event.CHANGE, changeHandler);
                                
                 this.addChild(newFormItem);
                 newFormItem.addChild(newTextInput);                                   
            }
  

  This is the class I want to get the value of newTextInput:

  package components{

                 required = false;           
                                
            }
  
            public function setupProperties(propertyInstance:PropertiesForm):void{
                 
                 propertyInstance.setText('Label','label',this.id);

  You need to understand the basics of the custom events, please read the Adobe LiveDocs page:

  Ching http://www.google.com/search?hl=en&q=Flex+3+dispatching+Custom+Events&AQ=1&OQ=Flex+3+dispa & AQI = g2

  So create a custom event and make the event type 'myEvent '.

  Can have a property of the custom event to the value of newTextInput.

  Your other class listens for the event and accessing the property of the event object that contains the value ofnewTextInput.

  You may need to add the event listener to systemManager:

  systemManager.addEventListener (MyCustomEvent.MY_EVENT, myHandler);

  My post Cookboo Flex deals with custom events. It's a bit long, but if operate you locally, it can clarify certain points.

• Passing a parameter to a custom event?

  OK, I almost have this figured out, but there's always a part that escapes me.
  
  I have a component that will dispatch a custom event 'ImageClicked' (see code). The component instance has a string variable ' var link: String. I pass a string of binding to this element when it is created, such as the purpose, say that the value is "" http://www.adobe.com ". "
  
  I want to raise this event to the main application and not the value of 'link' with the event, so my request then go to the Adobe homepage (in this example).
  
  I then this event listener: mainStack.addEventListener (ImageClicked.CLICK, goLink);
  
  My goLink function expects a string parameter, the value of 'link' in the component, in this case, I wish it were " http://www.adobe.com".
  
  Can someone please clear this up for me? I feel like I'm so close, but it is missing a key ingredient

  You must add an eventListener to listen for the event. First give an id to your custom component:

  Now you are calling a create1function that is not declared anywhere, then change the code of your application to this script:

  
  

  public void create1(): void
  {
  myForm.addEventListener ('stateChangeToEdit', stateChangeToEdit);
  }

  public void stateChangeToEdit(eventObj:Event):void {}
  currentState = "change"; I have to qualify the scope of application?
  }

  Try this and let me know if it worked

• Using the simple custom event

  I try to get a better understanding of the events and to create my own custom events and calling dispatchevent. This is in reference to a previous post here: http://www.adobe.com/cfusion/webforums/forum/messageview.cfm?forumid=60 & catid = 585 & threadid = 1329712 & enterthread = y
  
  Initially, I tried to get this working in the middle of a bunch of other things going on but could not get my disptachevent to trigger the listener that I had put in place. After messing around for a while, I decided to just pull this part out and try to get the basics of this work (I always have problems with). While I can find a lot of examples, listeners in action out of events predefined (such as mouse clicks) can't get a lot about what I'm trying to do. I don't know I am missing a simple property of the events and making a call wrong here but I can't understand what it is.

• Custom event is not captured by the Task Scheduler and unable to trigger by e-mail for the event

  Hello world

  We have installed the 9.0 table in our windows 2008 R2 server and Scheduler tasks to send if you find error occurred for the application in it. That's why we created SMTP inside. First, we have implemented the Task Scheduler and generate an error in the application of the table and run the task manually and we receive by e-mail. But when we go for automation by the custom event. The steps below that I follow:

  1. click the Start button, and then select administrative tools > Task Scheduler.

  2. click on the task of creating in the Actions pane on the right.

  3. in the dialog box create a task in the name text box, type a name for the task and provide a description if you want.

  4. in the section security options, select run whether user is logged in or not.

  5. click on the triggers tab, and then click the new button.

  6 to start the task drop-down list, select an event.

  7. in the settings section, select custom and click the new event filter.

  8. for the event level, select the error box.

  9. selection of the Source, in the event source drop-down list, select the table server checkbox.

  10. click OK to close the new dialog box even filter and then click OK again to close the new trigger dialog box. The event trigger is now configured.

  11. in the dialog box create a new task, click the Actions tab and click the new button.

  12. in the Action new dialog box, in the drop Action, select send e-mail.

  13. under the settings section, fill in the form as required, including the SMTP server.

  Note: It is necessary to enter the valid e-mail addresses in the From and to text boxes.

  14. click OK to close the new dialog Action.

  15. click OK to close the dialog box create a task and finish configuring e-mail alert.

  If please see this and feel free to contact me if you have any information.
