Standard input. the VM & vitual or custom events

I am interested in generating vitual events, that is code that generates events as if they originated from the real environment.
First sight of API does not present a possible "write" to the input stream. Or is there a way?
Alternatively, I wish to have a component/container that can say: "tell me about events of type customEvent", peferably from the AWT eventQ. I think thas is not really like the usual Listener model.
Or, customEvent to a specific Q that I must implement that serves responses to "customEvent" in a way that is coordinated with eventQ responses to real events.
Then, I need documentation about eventQ under the VM: where is this found.

You can set your component to listen for events which match a particular mask (mask types are defined in AWTEvent).

Dispatching Custom Event

Hello everybody,
Task: I want to enter a message in input text field and
write it in the dynamic using a custom event dispatching.
Solution: I have 2 textfields on the stage.
One textfield is an input text field the other is a dynamic
text field which will server just to display text.
on the flash in the first frame I made this code:
// mb is the instance name of the dynamic text field already
placed on the stage
var messageBoard:MsgBoard = new MsgBoard(mb);
// u1 is the input text field placed on the stage
var user1:UserInput = new UserInput(u1);
Also I wrote 3 very simple classes.
1. UserInput.as // input textfield class that listens to
input and dispatches a custom event
2. MsgEvnt.as // custom event class the instance of which is
dispatched
3. MsgBoard.as // class that listens to the new event and
once it occurs adding event message to the textfield
Problem: Somehow it doesn't work. I actually made it work by
making a listener the same object that dispatches the event. But I
want to understand why it doesn't works the way I showed above. I
browsed a lot of forums and found that all the people use to listen
by the same object that is dispatching. I think it's like talking
with yourself isn't it?
Thanks everybody who will reply and I hope it will help
someone who will read!

your event is dispatched within UserInput scope and MsgBoard
is not within UserInput scope so it's not going to receive that
event. ie, a UserInput instance is not accessible to MsgBoard.
you may have a basic misunderstanding: events that are
dispatched are not like radio signals that are transmitted and
anyone with a listener (radio) can hear them.
when you dispatch an event using actionscript, it is
dispatched by an object (or sometimes by a class) and that event
can only be detected by the dispatching object (or class).

How to Access Custom Event using AS3?

Hi All,
Maybe it's that its Monday morning and my brain is still foggy, but I can't seem to figure out how to set custom events using AS3.
I have a custom GridRow itemRenderer, and have declared the event using the appropriate metatags.
Then I create the GR item dynamically using AS3 instantiation, but the event is not available for selection in the intellisense drop-down.
Let's take the following as an example:
<?xml version="1.0" encoding="utf-8"?>
<mx:Grid
 xmlns:mx="http://www.adobe.com/2006/mxml"
 xmlns:renderers="com.brassworks.renderers.*"
 creationComplete="componentInit();"
>
 <mx:Script>
 <![CDATA[
 private function componentInit():void
 newRow :MyRow = new MyRow();
 //newRow.myEvent is not an available option to set
 ]]>
 </mx:Script>
</mx:Grid>
Then the itemRenderer:
<?xml version="1.0" encoding="utf-8"?>
<GridRow
 xmlns:mx="http://www.adobe.com/2006/mxml"
 xmlns:classes="com.brassworks.components.classes.*"
 creationComplete="componentInit();"
>
 <mx:Metadata>
 [Event(name="myEvent", type="flash.events.Event")]
 </mx:Metadata>
 <mx:Script>
 <![CDATA[
 private function itemChanged(event:Event):void
 Alert.show("test");
 this.dispatchEvent(new Event("myEvent"));
 ]]>
 </mx:Script>
 <mx:GridItem>
 <mx:TextInput
 change="itemChanged"
 />
 </mx:GridItem>
</GridRow>
How do I go about setting the handler method for custom events on instantiated items? Do I need to do this via the AddEventListener() method? Does this mean that events aren't exposed in ActionScript like they are in MXML? (In MXML all I have to do is <MyRow myEvent="handler(event)" />.)
Thanks!
-Mike

Yes, I you need to do this via the addEventListener() method.
myRow.addEventListener( "myEvent", myHandler );
I hope that helps.

Eventhandlers of children of application can not receive custom event dispatched by application

Hello dear Adobe community,
hope you can help me with this issue.
When the application dispatches a custom event, the child uicomponent can only receive the event by using Application.application.addEventListener or systemManager.addEventListener. Simply adding a listener, without application or systemmanager, does not allow the event to be received by the child component.
I want to be able to use the addEventListener and removeEventListener without SystemManager or Application.application, or could you provide a better workaround? How can I use the addEventListener, do I need to overwrite EventDispatcher, which I wouldnt like to do?
Just to clarifiy, if i remove the systemManager in front of addEventListener(CustomEventOne.EventOne,sysManHandleCE,false) it will not add it and will not fire.
The code below is an example for this problem that the event is not getting fired in the right moment. The mainapplication got only a button with the customEventOne that gets dispatched.
public
class MyCanvas extends Canvas{
public function MyCanvas()
super();
width=300;
height=300;
addEventListener(FlexEvent.CREATION_COMPLETE,handleCC,false,0,true);
private function handleCC(event:FlexEvent):void
removeEventListener(FlexEvent.CREATION_COMPLETE,handleCC);
addEventListener(CustomEventOne.EventOne,handleCE,false,0,true);
addEventListener(Event.REMOVED_FROM_STAGE,handleEvt,false,0,true);
systemManager.addeventListener(CustomEventOne.eventOne,sysManHandleCE,false,0,true);
private function handleEvt(event:Event):void
trace("In removed from stage handler");
systemManager.removeEventListener(CustomEventOne.EventOne,sysManHandleCE);
trace(hasEventListener(FlexEvent.CREATION_COMPLETE));
trace(hasEventListener(CustomEventOne.EventOne));
trace(hasEventListener(Event.REMOVED_FROM_STAGE));
private function handleCE(event:CustomEventOne):void
trace("I got it");
private function sysManHandleCE(event:CustomEventOne):void
trace("I got it");
public class CustomEventOne extends Event
public static const EventOne:String = "EventOne";
public function CustomEventOne(type:String, bubbles:Boolean=false, cancelable:Boolean=false)
super(type, bubbles, cancelable);
override public functionclone():Event
return newCustomEventOne(type,bubbles,cancelable);
Thank you in advance,
Michael

I think you need to look at event propogation. The object that dispatches an event will be sitting on the display tree. The event propagates up the tree to the roots. Your canvas should be attached to the application, but even then it sits lower in the tree branches than the event dispatcher, so it won't see the event being dispatched because the event is not propagated to the children of the object that dispatches it but to the parent of the object that dispatches it.
So, your canvas is a child of the application, but dispatching the event from the application means that the canvas doesn't see it because events are notified up the tree using the parent link, not the child links.
You may wish to investigate how the display list and event propagation works and then the MVC pattern.

Custom Events are repeating with the standard events

Hello All,
I am facing a problem with the customization of standard OA Page.
We have modified the page by adding a new custom region with three buttons in it. We have also developed a controller for that region to handle the events. when a button is clicked, a new page opens up in a new window.
I have observed that the custom controller is called when any event occurs in the page irrespective of the region.
Now the actual problem is whenever any of the custom buttons are clicked, according to the requirement the new window opens up. But if we perform any other standard events in the page like clicking a standard LOV immediately after performing the custom event, then that most recent custom event is repeating with that standard event.
how to prevent this repetetion of custom event with standard event?
please help me solve this problem..
Thanks in advance.

For your page, are you setting the controller class for your various regions in the property inspector?

Restrict all the text in a datagrid input without having to create custom item renderers

Is there a way to restrict all the text in a datagrid input
without having to create custom item renderers for each
column?

How are you trying to restrict it? If you're trying to
restrict it uniformly, for example, to entirely numerical inputs,
then the easiest way I know of to do so is with an itemEditor. You
can just add the same itemEditor to each column that way.
This only saves work over custom renderers if you're trying
to restrict multiple columns in the same manner, but for numeric
only tables, it's pretty short.
You could probably also do it with itemEdit and
itemEditBeginning events, but that would likely be more work then
simply declaring a single global itemEditor and using it in all
your columns.

Custom event not traced in the SWEL transaction

Hi Experts,
In my development server I have created a custom BOR ZBUS2078 with few custom events and delegate it to the standard BOR BUS2078.
I have moved the same to quality. But i could not find the trace for the custom events of ZBUS2078 unlike the standard events of BUS2078 in the SWEL transaction .
However those custom events are getting triggered in my development server.
I have checked the delegation and the custom BOR in the quality and they are same as in development server
Object type : BUS2078
Delegation type : ZBUS2078
What could be the problem and how to resolve it?
Please provide your valuable solution and suggestions.
Thanks in Advance.
Regards
K Arasu

Issue resolved. I have maintained those custom events in SWEC in quality server.

Custom eventing for reporting --- am i using the correct ResourceEvent?

Hi All,
I am using a web content management tool which stores all the content created through the tool in /documents repository . This content is published in the portal under various roles . I am working on a report to generate and report the hit counts for the pages in this repository . I have written a Km service that subscribes to GET_TEMPLATE event to generate these statistics.
The problem i am facing is this . When i navigate through the KM folder structure to a given page in a subfolder and do a preview of the page content , the hitcount is incremented and the report reflects this increase . However if i navigate to the role where the content is published and view the content from the role , the page hit count is not incremented and the report does not show the increment .
My questions are
1) Do i need to write a custom KM event that notifies the repository broker about
the page access through the roles?
2) Is there any other standard event to which i can subscribe to get this page hit count.
Any helpful answers will be rewarded.
regards
Subra

Hi Subra,
> is there any way to know if the tool is raising any event
As I have been one of the developers, I can report that the tool definitely does not raise such an event explicitely. But as said above, it also shouldn't do this, as it shouldn't be needed. In addition, for the display the tool redirects to a KM navigation iView, which normally should lead to the expected event risen anyhow.
But if it really doesn't work, you still have the option to ask btexx to check if this is a shortcoming on SAP side - which in the interest of a smooth working product should be tracked, maybe worked around...
About the caching I can report that there is also no caching used at the moment for the display. This may change one day, for this in fact it would make sense to raise the event (even if the resource isn't called from the framework, but to enable such kind of statistics, if they won't be part of the product one day anyhow).
Hope it helps

One additional remark for all people involved: I just remember to have read about the same "missing" event on SDN, but I never checked this in the end. It might be that the navigation iView only throws the getChildren event, as for other resources than XML forms elements, it only renders the name of the resource, not it's (or part of it's) content (so the content doesn't get accessed). This also would make sense as normally the access to the Show form could be differentiated from the access to the RenderListItem form.

How to receive the custom event in the listening portlet (No backing file)

I have couple of portlets (JPF based). Portlet A is firing an event
     public Forward processAction()
          PortletBackingContext context =PortletBackingContext.getPortletBackingContext(this.getRequest());
          String message = "XXXXX";
          context.fireCustomEvent("customevent", message);
          Forward forward = new Forward("success");
          return forward;
I have configured the Portlet B's eventhandler to listen for the 'customEvent' and invoke the pageFlowAction 'listenForEvent'
     @Jpf.Action(forwards = { @Jpf.Forward(name = "success", path = "test2.jsp") })
     public Forward listenForEvent() {
          Forward forward = new Forward("success");
          return forward;
Portlet B's method listenForEvent is indeed getting invoked, but is there a way I can retrieve the 'Event' object (as fired by Portlet A) inside the listenForEvent. I could have done this via the Backing file, but for some reasons i cann't use the backing file. Is there a way i can get the CustomEvent and the associated payload in my listening JPF portlet, without a backing file?
The WLP version is 10.3

Hello,
I originally said:
All you should need to do is to modify the method signature for your event-receiving method. The method signature should be:
public void listenforEvent(HttpServletRequest request, HttpServletResponse response, Event event)
where Event is a com.bea.netuix.events.Event object. You can then cast this to a CustomEvent object.
But I mis-read your earlier post about catching the custom event and invoking a pageflow action. When you do that, you will lose the custom event's payload (your message), and there is no way to retrieve it from your pageflow action.
The only way you can actually retrieve the event's payload is using a backing file for the portlet, with a method having the signature I mentioned above. You can then set a request attribute with the event's payload and still have it invoke the pageflow action, at which time you could retrieve the request attribute value-- assuming you don't need to run this portlet over WSRP. Over WSRP, the event-handling and pageflow action-invoking lifecycles will happen with independent request objects, so you would need to store the event payload in session to work over WSRP.

Using Labview's System Exec.vi, is there any way to send multiple standard inputs to the same executeable console? Or is there a way using Labview to target the window for the executeable and send commands to it at will?

thanks

One suggestion is to write a batch (.bat) file that will call your executable. The batch file can contain all the standard inputs necessary to run the executable. Then, in LabVIEW, you can call the .bat file using the System Exec.vi.
As far as your second question, there is no slick way to do this LabVIEW. You would probably have to call Window API functions using the Call Library Function utility. There is a set of VI's that call some of the standard API functions but I don't think they have what you want.

How to define custom event and how to trigger the defined event

hi,guys
hurry issue....................hope get help.
I am using oracle weblogic 10gr3 portal.and we choiced java portlet.as of now,we got some question about custom Event.hope you can give some idea....
thank you so much.
question detail:
1.for java portlet ,how to define custom event.
2.how to trigger this event.
3 about the data,may be sometime need to transit Biz data.
auctully,I just want to implements between two portlets communicate.
for example:
existing portletA,portletB.
portletA is a list,like:
A AA <button>
after I click this buttom,then portletB will be effect,it means they are interact with each other.
does anybody hit this issue before,if you solved pls share me .
thank you for you help....

Hello,
Please note that everything below applies to JSR168 portlets ONLY- JSR286 portlets and other portlet types handle events a little differently.
From inside your JSR168 portlet you can send an event during processAction or when receiving another event by using the PortletBackingContext object, such as:
import javax.portlet.ActionResponse;
import javax.portlet.ActionRequest;
import javax.servlet.http.HttpServletRequest;
import com.bea.netuix.servlets.controls.portlet.backing.PortletBackingContext;
public void processAction(ActionRequest actionRequest, ActionResponse actionResponse)
HttpServletRequest httpRequest = (HttpServletRequest) actionRequest.getAttribute("javax.servlet.request");
PortletBackingContext portletBackingContext = PortletBackingContext.getPortletBackingContext(httpRequest);
portletBackingContext.fireCustomEvent("customEvent", "This is a custom event");
To receive an event, in your .portlet file you just need to put in a "handleCustomEvent" tag specifying which method to call when the event is received, such as:
<?xml version="1.0" encoding="UTF-8"?>
<portal:root xmlns:netuix="http://www.bea.com/servers/netuix/xsd/controls/netuix/1.0.0"
xmlns:portal="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.bea.com/servers/netuix/xsd/portal/support/1.0.0 portal-support-1_0_0.xsd">
<netuix:javaPortlet title="Listening Portlet" definitionLabel="yourPortletName">
<netuix:handleCustomEvent event="customEvent" eventLabel="customEvent" filterable="true" description="custom event handler">
<netuix:invokeJavaPortletMethod method="processCustomEvent"/>
</netuix:handleCustomEvent>
</netuix:javaPortlet>
</portal:root>
Then, in your receiving portlet the method "processCustomEvent" would receive the event, such as:
public void processCustomEvent(ActionRequest actionRequest, ActionResponse actionResponse, Event event)
The event payload can be any Serializable object you want, but for forward-compatibility with JSR286 it would be ideal if it had a valid JAXB binding.

APP-FND-01926 The Custom Event WHEN-LOGON-CHANGED...

Hi,
After compiling and placing a 'custom' CUSTOM.pll (and plx) file on the server, when logging into Applications receiving ERROR:
APP-FND-01926 The custom event WHEN-LOGON-CHANGED raising unhandled exception: User Defined exception.
This is for R12.1.3
The code was moved to the original base version of the R12 CUSTOM.pll file...
I read many other Notes on this error, but most refer to an error related to a Program Unit Not found and requiring a regeneration of the JAR files.
Would this be the same situation?
When we place the original back in place the forms login works.
Any ideas?
Thanks,
Lamonte

check ur CLASSPATH environment variable ur Custom.plx library should visible on runtime to Classpath variable.
