Event propagation

Hi,
SAP has standard functionality of event propagation from FU to FB and vice versa.Now if I want to stop event propagation or event cascading functionality from FB to FU do I need to remove any code logic check in the extractor? Can you elaborate in details here.
Secondly how does preprocessing functionality help in ENM functionality. What specific checks can eb brought about if w ewant to implement this functionality

Hi Dipak,
Extract the FU number as TOR_TEC tracking id from TM shown below
FU EH TRacking ID table
Tr.Code.Set
Tracking id
FU
123456
TRQ
987563
TO
458796
TOR_TEC
123456
Define the Tracking id Code Set(TOR_TEC) in Event reporting items under event message profile , configure only to particular internal event code which does not requires event propagation to FB.
Above configuration supported only when the event posted via EM WebUI,
you have to apply the same logic in BADI for interface event posting.
Regards
Sukumar

    Since keyboard are now cancellable, the Spark components should use event.preventDefault() / event.isDefaultPrevented()  instead of event.stopPropagation. I updated ButtonBar, RadioButton, and DropDownList to use preventDefault(). Also cleaned up Slider and Spinner to always assume the event is cancellable.

  • Stopping Event Propagation

    Hi All,
    Am facing some issue in event propagation.
    I have a Application component with in which I have a link button. The Application has a mouseDown event listening for it and the link button has the click event listening for it.
    I have a requirement where in if i click on the link button i got to show an image and on again clicking on the link button hiding the image. Basically toggling the hide/show of image on click of the link button. This works fine as expected.
    Now I have mouseDown listening on the Application, where in If I click any where else in the Application again the Image show be hidden and only on click of Link button it should be shown.
    But since I have the mouseDown listening on the Application, whenever I click on the Link button the image is showing properly but then after that when I click the link button again to hide the image, then since two events are getting triggered  the Image is never getting hidden. It always shows up.
    THE FIX I NEED is that when i click on the link button, the parent event should be stopped from bubbling and hence only the Link Button's Click should be called and not the Application's mouseDown.. And in else other places, its fine to have the Application's mouseDown event called.
    I Tried event.stopPropagation () and event.stopImme()...but in vain.......... PLS HELP

    I don't think you can preventDefault on key events. You could
    probably use
    ExternalInterface to tell the web page not to listen for the

  • Event propagation API

    Hi,
    I recently started using Flex and read through the, very extensive and well written documentation. I read about the event propagation mechanism and was rather stunned that only Objects that have a parent-child relationship take part in event propagation. At first I couldn't believe it but trying to connect to objects that were at very different parts of the display list showed, that the events really do not get delivered! Wouldn't it be better to have a more general mechanism that does not care about the wherabouts of the components? I mean, what if I want to synchronize some model objects that are not even part of the display list with some UI Element they have a relationship with? The target phase doesn't work because its not the model that throws the event (of course!). Or do I miss something here?
    I was expecting a more subject-observer like pattern,  that allows me to connect whatever I want with whatever there is left. So, how do I do that. Do I have to right my own little event dispatching library (what would not be so difficult, but I would rather use something that has already proven its liability)? Can anybody recommend me a good API for that or tell me that I am dead wrong and missing something important?
    Regards,
    Benni

    Only DisplayObjects support bubble and capture propagation.  In a tree of
    regular Objects, as long as you attach a listener to the right object, you
    will be able to get its events.
    Bubble and capture are very dangerous as they break encapsulation.  We only
    use them for situations where the target is unpredictable like in mouse and
    keyboard interaction.  I would probably not use it in a data object tree.
    Maybe if you provide a more explicit example of what you are trying to
    accomplish and what you tried, folks on the forum can help.

  • Mobile IconItemRenderer - prevent event propagation

    Hello,
    I don't want anything to happen when an element is clicked or touched in a mobile itemRenderer extending IconItemRenderer.
    Isteand of overriding the drawBackground method and not listening for the change event, is there anyway of doing this faster, like preventing the event from propagating?
    Thank you.

    1. commitProperties seems fine
    2. I assume it would be faster since you avoid unnecessary drawBackground calls.  You might want to test to make sure.
    3. Correct, if you can't click on something it won't be able to fire a mouseDown event
    4. The mouseDown listener is added to the renderer in List.dataGroup_rendererAddHandler.  You could tweak it there, but that would require a subclass of List.  I typically find it easier to do from within the renderer via one of the two approaches I mentioned above especially when that changes based on the data in the renderer.
    5. The Flex SDK currently deals exclusively with mouse events.  See the "Mouse vs. Touch Events" section of this spec for more information: http://opensource.adobe.com/wiki/display/flexsdk/Mobile+List%2C+Scroller+and+Touch

  • Event propagation in mediumweight components

    Hi,
    There's an article "Mixing heavy and light components":
    http://java.sun.com/products/jfc/tsc/articles/mixing/
    It explains mouse event handling:
    "Mouse events on a lightweight component fall through to its parent; mouse events on a heavyweight component do not fall through to its parent. "
    What about mediumweight components? Are mediumweight components receiving mouse events like lightweight or like heavyweight components?
    Is it possible to infer how the mouse events are propagated just by using JComponent.isLightweightComponent()?
    Kari

    What do you mean by sub-app .  Are you using modules ?  For regular situations you can set "bubbles" to true on the event.

  • Stopping an event propagation

    Hi!
    I want to provide hotkey in my html webpage. (I am using
    http://code.google.com/p/js-hotkeys/)
    I also have a chat module in Flex. When I am typing some text
    in the flash object, I don't want the hotkeys to be enabled.
    I tried to stop the propagation from the flash but it's not
    working.
    From what I know, the html events are propagated from the
    child to the parents. So if I stop the event from my flash object
    it has to be ok, right?
    See my example. If I display an Alert from the callback, it
    is displayed, so it works. Why the event is still propagated?
    Thanks

  • Event Propagation again. Sorry

    Hi guys, I vave a pretty simple app to test how the propagation works.I do not undestand, why the propagation on the stage 3 (bubbling) works in the oppsit way than it should work.
    Here is my code:
    <?xml version="1.0" encoding="utf-8"?>
    <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
                xmlns:view="view.*" initialize="init()">
    <mx:Script>
    <![CDATA[
         import mx.controls.Label;
         import mx.events.FlexEvent;
         import mx.controls.Button;
         import mx.controls.Alert;
         import flash.events.TextEvent;
         private function init():void {
              this.addEventListener(MouseEvent.CLICK, handleTestEvent);
              vBox2.addEventListener(MouseEvent.CLICK, handleTestEvent2);
              vBox1.addEventListener(MouseEvent.CLICK, handleTestEvent1);
         private function handleTestEvent2(event:MouseEvent):void {
              Alert.show("This is VBox2  " + event.eventPhase );
         private function handleTestEvent1(event:MouseEvent):void {
              Alert.show("This is VBox1  " + event.eventPhase);
         private function handleTestEvent(event:MouseEvent):void {
              Alert.show("This is Application  " + event.eventPhase);
    ]]>
         </mx:Script>
              <mx:VBox id="vBox2">
                   <mx:VBox id="vBox1">
                        <mx:Button id="testButton" label="Click Me" />
                   </mx:VBox>
              </mx:VBox>
         </mx:Application>
    So, when I run this application, the first popup I see is: This is Application 3. Then: This is VBox2 3  and the last one: This is VBox1 3. But as I understud the order should be: This is VBox1 3,  This is VBox2 3,  This is Application 3.
    Could some body explain what's wrong?
    Thanks.

    The Alert boxes sit on the top of the display.
    When you get the first alert, it appears over the content.
    When the second happens it sits over the first alert.
    Then the third happens and sits over the second.
    So, when you see the third alert, it looks like there is only one box, but there are two underneath - hidden.
    You dismiss the third alert and see the second.
    You dismiss the second and see the first.
    It looks like the order is reversed, but in fact the order is correct and they have just popped up over each other. It feels that dismissing the third alert causes the second alert to popup, but it doesn't - it was there all along.
    Alert isn't synchronous.

  • Event propagation and inheritance

    Hi,
    I have a button inheriting from another. In the ancester I have a CLICK event handler registered.I have another CLICK event handler in the descendent button. In the descendent I want to handle the CLICK event combined with the CTRL key. Without the CTRL key I want the the ancester event handler to do it's work. I tried different combinations of StopPropagation(), StopImmediatePropagation priorities, etc...with no satisfactory result. Sometimes both event handlers are triggered, sometimes only the event handler for the descendent is triggered. What would be the way to do this. Thanks in advance.

    Thanks Natasha,
    I solved my problem by overriding the click event handler in the descendent like:
    override protected function clickHandler(event:MouseEvent):void {
         if (event.ctrlKey) {
              ...do the stuff in case of CTRL-key held
         } else {
              // Do ancestor work for normal click         
              super.dispatchEvent(event)
    So...no need for stopping propagation of the event

  • Help with understanding key event propagation

    Hello,
    I am hoping someone can help me understand a few things which are not clear to me with respect to handling of key events by Swing components. My understanding is summarized as:
    (1) Components have 3 input maps which map keys to actions
    one for when they are the focused component
    one for when they are an ancestor of the focused component
    one for when they are in the same window as the focused component
    (2) Components have a single action map which contains actions to be fired by key events
    (3) Key events go to the currently focused component
    (4) Key events are consumed by the first matching action that is found
    (5) Key events are sent up the containment hierarchy up to the window (in which case components with a matching mapping in the WHEN_IN_FOCUSED_WINDOW map are searched for)
    (6) The first matching action handles the event which does not propagate further
    I have a test class (source below) and I obtained the following console output:
    Printing keyboard map for Cancel button
    Level 0
    Key: pressed C
    Key: released SPACE
    Key: pressed SPACE
    Level 1
    Key: pressed SPACE
    Key: released SPACE
    Printing keyboard map for Save button
    Level 0
    Key: pressed SPACE
    Key: released SPACE
    Level 1
    Key: pressed SPACE
    Key: released SPACE
    Printing keyboard map for Main panel
    Event: cancel // typed SPACE with Cancel button having focus
    Event: save // typed SPACE with Save button having focus
    Event: panel // typed 'C' with panel having focus
    Event: panel // typed 'C' with Cancel button having focus
    Event: panel // typed 'C' with Save button having focus
    I do not understand the following aspects of its behaviour (tested on MacOSX although I believe the behaviour is not platform dependent):
    (1) I assume that the actions are mapped to SPACE since the spacebar clicks the focused component but I don't explicitly set it?
    (2) assuming (1) is as I described why are there two mappings, one for key pressed and one for key released yet the 'C' key action only has a key pressed set?
    (3) assuming (1) and (2) are true then why don't I get the action fired twice when I typed the spacebar, once when I pressed SPACE and again when I released SPACE?
    (4) I read that adding a dummy action with the value "none" (i.e. the action is the string 'none') should hide the underlying mappings for the given key, 'C' the my example so why when I focus the Cancel button and press the 'C' key do I get a console message from the underlying panel action (the last but one line in the output)?
    Any help appreciated. The source is:

    Use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.
    1) In the Metal LAF the space bar activates the button. In the Windows LAF the Enter key is used to activate the button. Therefore these bindings are added by the LAF.
    2) The pressed binding paints the button in its pressed state. The released binding paint the button in its normal state. Thats why the LAF adds two bindings.
    In your case you only added a single binding.
    3) The ActionEvent is only fired when the key is released. Same as a mouse click. You can hold the mouse down as long as you want and the ActionEvent isn't generated until you release the mouse. In fact, if you move the mouse off of the button before releasing the button, the ActionEvent isn't even fired at all. The mouse pressed/released my be generated by the same component.
    4) Read (or reread) the [url http://java.sun.com/docs/books/tutorial/uiswing/misc/keybinding.html#howto]How to Remove Key Bindings section. "none" is only used to override the default action of a component, it does not prevent the key stroke from being passed on to its parent.

  • Swing Mouse Event Propagation

    Hello,
    I'm developing my first Swing application.
    One of the components is a thumbnail image panel (ext. JPanel) containing several other components (mostly ext. JLabel). I have the image panel receiving mouse events so as to allow the user to see when the image panel is 'in focus' (rollover effect basically) and to allow the image panel to be selected by clicking.
    I added a tooltip to one of the contained labels, and it now 'consumes' my mouse enter/exit event so that now it is as if the label is not part of it's container. This is not what I want.
    Is there not some simple way to allow mouse events to be listened for by a child component but yet to 'fall through' to a listener in the parent component?
    Any insight into this little problem would be most appreciated.
    Thanks.

    You can listen to all MouseEvents generated:
    Toolkit.getDefaultToolkit().addAWTEventListener( new AWTEventListener()
         public void eventDispatched(AWTEvent e)
              System.out.println(e);
    }, AWTEvent.MOUSE_MOTION_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK);You would then need to determine if the source component is a descendent of your main panel.

  • Event propagation in AS3/Flex 3.3

    How to bubble up event from sub-app loaded into child application domain to the main app?

    What do you mean by sub-app .  Are you using modules ?  For regular situations you can set "bubbles" to true on the event.

  • Event propagation from child application to main application

    Hi,
          I am using SWFLoader to load third party component into our main application.we are trying to create annotation feature on top of child application.for that main application needs to receive events e.g. mouse events from child application.can anyone suggest whether this is possible ?
          I found pdf doc from help of SWFLoader component on flex developmenent center.It has an example in which child application uses SystemManager to register event listner for main application.so is it that we need to register listener from child application so main application receive events ?
       Thanks in advance.
    Thanks and regards,
    Rakesh Parmar

    If you examine the urls and the domains are the same then you don't have a cross-domain problem, but then your symptoms remain unexplained.
    Note that Flash just checks the text of the domain/sub-domain so http://localhost/ is different from http://10.0.0.127/ or whatever its IP equivalent is.

  • Can you make an enter event in topmostsubform that gets the field name of any field thats entered

    Looking for some help.
    I have a modified Enter Event I'm trying to use. What my expected results are: When you click on a field on the PDF, it would open up a certain webpage or file depending on what field is entered. I currently have:
    if (xfa.host.name == "Acrobat") {
              app.launchURL("www.cnn5.com" + "/" + event.target.documentFileName + "&" + this.name, true);
    else {
              xfa.host.gotoURL("www.cnn5.com");
    In this example, i'm using a bogus address obviously. "event.target.documentFileName" gives me the PDF name which is what I want, but I need to scrub off the ".pdf" at the end of it. I know I can use this in every field that I want it in, but I'm looking to see if I can get this code in just the topmostsubform only due to having hundreds of forms I might be using this form and to save time.
    When this is used in the topmostsubform, it gives me the URL: "www.cnn5.com/PDFname.pdf&TopmostSubform" no matter what field i click into. Is there something i can change this.name to? Any help would be greatly appreciated.
    Also, i'll need to have this event to be able to use multiple times, because currently in the topmostsubform, it only activates on the first field that I enter and doesn't activate on fields after that. Suggestions please? Thank you

    Hi,
    Are you using event propagation?  If you are try

  • Event Bubbling Custom Object not inheriting from control

    One of the new things flash flex and xaml have are ways which

    it.
    My goal is to use the frameworks event system on custom
    objects. My custom objects are:
    ApplicationConfiguration
    through composition contains:
    SecurityCollection which contains many or no SecurityElements
    and
    FileSystemCollection.cs which contains many or no
    FileSystemElement objects
    ect ect basically defining the following xml file with custom
    objects.
    [code]
    <ApplicationConfiguration>
    <communication>
    <hardwareinterface type="Ethernet">
    <ethernet localipaddress="192.168.1.2" localport="5555"
    remoteipaddress="192.168.1.1" remoteport="5555" />
    <serial baudrate="115200" port="COM1" />
    </hardwareinterface>
    <timing type="InternalClock" />
    </communication>
    <filesystem>
    <add id="location.scriptfiles" value="c:\\" />
    <add id="location.logfiles" value="c:\\" />
    <add id="location.configurationfiles" value="c:\\" />
    </filesystem>
    <security>
    <add id="name1" value="secret1" />
    <add id="name2" value="secret2" />
    </security>
    <logging EnableLogging="true"
    LogApplicationExceptions="true" LogInvalidMessages="true"
    CreateTranscript="true" />
    </ApplicationConfiguration>
    [/code]
    basically these custom objects abstract the xml details of
    accessing attributes, writing content out of the higher application
    layers.
    These custom objects hold the application configuration which
    contains the users options. The gui application uses these
    parameters across various windows forms, modal dialog boxes ect.
    The gui has a modal dialog that allows the user to modify these
    parameters during runtime.
    basically i manage: load, store, new, edit, delete of these
    configuration files using my custom objects.
    Where would event propagation help in custom objects like
    described above?
    ConfigurationSingleton.getInstance().ApplicationConfiguration.CommunicationElement.Hardwar eInterfaceElement.EthernetElement.RemoteIPAddress
    =
    System.Net.IPAddress.Parse(this.textBoxRemoteEthernetIpAddress.Text);
    The EthernetElement should propagate a changed event up to
    the parent ApplicationConfiguration which would persist this to the
    registry, db, file or whatever backend.
    currently this logic is maintained else where. I serialize
    the root node which compositely serializing the nested nodes and i
    check of the serialization is different from that in the backend
    … This tells me if the dom was modified. It works but i would
    like an event driven system.
    how should i implement bubbling using custom objects?
    3 implementation ideas:
    1) A simple way is to implement a singleton event manager:
    EventManager.RegisterRoutedEvent
    http://msdn2.microsoft.com/en-us/library/ms742806.aspx
    I like this idea but how can you tell which object is nested
    in who… this way the event can be stopped and discontinue
    propagation?
    2) If i use binders as discussed in Apress’s book:
    Event-Based
    Programming Taking Events to the Limit
    basically a binder connects the events between seperate
    objects together… although it would work for my app, I would
    like a more generalized approach so i can reuse the event system on
    future project.
    3) how does flash flex handle this..
    objectproxy.as?
    http://www.gamejd.com/resource/apollo_alpha1_docs/apiReference/combined/mx/utils/ObjectPro xy.html#getComplexProperty()
    >Provides a place for subclasses to override how a complex
    property that needs to be either proxied or daisy chained for event
    bubbling is managed.
    how does these systems all work....? Reflection ?
    this way i can simulate this on my own custom classes.
    Thanks!

    I have a strong sensation that the OSMF project is quite dead.
    no new submits since 2010, the contact form on the offical OSMF
    project website http://www.opensourcemediaframework.com/
    returns a PHP error.
    and many unanswered questions about OSMF in this forum.
    i think it would be wise to not use OSMF if possible, although
    I'm also stuck with it since we are utilizing HDS/PHDS
    protocols which are utilized in the framework.
    otherwise its quite a head-ache.
    I'm unable to get to a video element coming from a proxied element
    that is being produced via an HDS connection.
    and haven't found any solution that works.
