WF: Problem in raising event of a class in ABAP code to complete workitem.

Hi All,
I'm developing a workflow of Hiring Eform.
In this workflow we have created a step for some data processing and also set termination event for the task inorder to complete the task.
Now problem is that how to trigger the event of this class in the abap code so that the workitem will be completed.
As far as i know i have used following function module to raise a event for BOR. but is there any way to raise/trigger the event of Class.
For BOR: SAP_WAPI_CREATE_EVENT

[Note 1322202|https://service.sap.com/sap/support/notes/1322202] provides SAP_WAPI_CREATE_EVENT_EXTENDED which can do classes.

Problem while using a methid or class in ABAP code.

Hi,
I want to fetch the personalization data for a user from SU01. I guess there is method called get_data of class CL_PERS_ADMIN which I can use to fetch the data. How can I use this in my custom program.
I directly used like this:
LOOP at I_KEYROLEUSERS.
call method CL_PERS_ADMIN->GET_OBJECT
    exporting
      p_pers_key          = 'LAW_PERS'
      p_uname             = I_KEYROLEUSERS-UNAME
     p_rfc               = p_rfc
    receiving
      p_object            = p_object
    exceptions
      default_not_set     = 1
      internal_error      = 2
      user_does_not_exist = 3
      pers_key_not_found = 4
      rfc_connection_failed = 5
      others              = 6.
ENDLOOP.
But I get an error saying "Field CL_PERS_ADMIN->GET_OBJECT" is unknown. It is niether one of specified table nor defined by 'DATA' statement.
Regards,
Rajesh.

Data: lcl_pers_adm TYPE REF TO CL_PERS_ADMIN.
CREAT OBJECT lcl_pers_adm.
LOOP at I_KEYROLEUSERS.
call method lcl_pers_adm->GET_OBJECT
exporting
p_pers_key = 'LAW_PERS'
p_uname = I_KEYROLEUSERS-UNAME
p_rfc = p_rfc
receiving
p_object = p_object
exceptions
default_not_set = 1
internal_error = 2
user_does_not_exist = 3
pers_key_not_found = 4
rfc_connection_failed = 5
others = 6.
ENDLOOP.
Try with the above code.

The application name is not necessarily uniqueue! Customers may create two applications with same name in different systems/clients and transport them into the same target system/client!
You do the mapping with the query:
CL_FDT_FACTORY=>GET_INSTANCE( )->GET_QUERY()->...
There are two methods. One for mapping ID to name and one for name to ID.
There is also a sample report in package SFDT_DEMO_OBJECTS.

How can i raise events from a class?

Hi all, i've a problem with events.. how can in java to raise an event and to catch him?
For example i have ha class Counter like this:
public class Counter
int[] vettore = new int [10];
int vetCnt = 0;
void addNumber(int number)
if (vetCnt < 10)
vettore[vetCnt++] = number;
for(int n=0;n<vetCnt;n++)
System.out.print(vettore[n]);
System.out.println();
else
System.out.println("Vector full!");
The main class is like this:
public class Main
public static void main(String[] args)
Counter cnt = new Counter();
MyEventListener listener;
cnt.addNumber(0);
cnt.addNumber(1);
cnt.addNumber(2);
cnt.addNumber(3);
cnt.addNumber(4);
cnt.addNumber(5);
cnt.addNumber(6);
cnt.addNumber(7);
cnt.addNumber(8);
cnt.addNumber(9);
cnt.addNumber(10);
cnt.addNumber(11);
cnt.addNumber(12);
Now what i i want to raise an event that i can catch in the main class instead of print a message? I know how to do this in C#, but in Java is very different..
Thank you

How to Raise Event in BW using ABAP program

Hi BW Experts,
Can anyone tell how to raise event in BW using a ABAP program.
Program should ask for the event to be raised and destination server.
Edited by: Arun Purohit on May 14, 2008 11:04 AM

Hi Arun,
By Using BP_EVENT_RAISE function module you can raise an event.Create an ABAP program and call the function module BP_EVENT_RAISE and create a avariant to specify the event to be raised. Schedule this ABAP code. Go to the start process type and set the schedule to "after event" and mention the event name that you created. Also, I think now you can mention the time as well and you can also schedule for periodic scheduling.
T Code : SM62 --> To Create an Event.
T Code : SE38 --> To Create an ABAP Program
Use Function Module : BP_EVENT_RAISE to raise an event.

Taskflow Raise event foucs problem

Hi,
We are using Oracle ADF JDeveloper version 11.1.1.4 (released version) for our development.
We have used several taskflows / reusable taskflows in our application. For most of the taskflows we have "raised events".
However we are facing strange problem with the same.
For example:
Consider a screen where height of the screen is more than the WINDOWS height. For such a screen vertical scroll bar will be there.
There is a taskflow which is at the bottom of the screen. To see that taskflow user will use the vertical scroll and will reach there.
If USER performs any action on this taskflow then events get fired correctly but the focus atomically gets shifted to first element of the screen. Due to this behavior USER needs to scroll the screen every time which is irritating. If we disable the raise event focus doesn’t shift.
Can somebody look into this?

Hi,
customer support would be a good point of contact for analyzing the problem if you have a test case. I can only assume you are talking about contextual events ?

Problem in handling Before_User_Command Event in CL_GUI_ALV_GRID class

Hi,
I have created an ALV grid control and I am also handling the before_user_command event of cl_gui_alv_grid class.
My aim is to use POPUP_TO_CONFIRM function module when the users click on the add/delete row button.
Control is going to the event if I am clicking on any other button of the control except add/delete row buttons.
And in the class attributes those operation description is saying they are local.
Please let me know how make control to go to before_user_command event when users click on add/delete button.
Thanks in advance,
Suneel C

Hi Suneel,
For you requirement, I dont see why you cant include the functionality for the pop up within the USER_COMMAND event itself.
Algorithm for the USER_COMMAND event:
Step 1: Check E_UCOMM is 'ADD' or 'DELT'.
Step 2: If yes, call FM for POPUP_TO_CONFIRM; else continue to other E_UCOMM
Step 3: If ans is 'No', exit Method - else continue with Add/ Delete as required
Cheers,
Aditya

ALV: Problem with toolbar event

Hi ALV-experts,
I have a dynpro with a header area where I display an ALV table. Below this I have a subscreen with a tabstrip control and two tabs.
In the ALV toolbar I defined an own button. This button gets deactivated after pressing this button. I achieved this by the option "disabled" in the structure stb_button within the event handler for the toolbar event.
This works all fine so far. If I start the dynpro and click on the button in the ALV-toolbar the buttons gets deactivated afterwards. But I have I jump between the tabs before I press the ALV-toolbar button, the button does not get deactivated.
The debugger does not go into the event handler of the toolbar event. I also did system debugging of the method SET_TOOLBAR of the CL_GUI_ALV_GRID-class. Here I pass in both cases the command
raise event toolbar e_object = m_cl_toolbar e_interactive = i_interactive.
but in the second case (when I change the tabs before I press the button) the event handler is not executed and I don't know why. I also tried to register the event handler for all instances of the ALV still with the same result.
The ALV method set_toolbar_interactive( ) did also not solve the problem.
I couldn't find any SAP note about an issue for this event.
Does anybody have an idea or a solution for this problem?
EDIT:
Problem solved, it was typo!
Thanks in advance and regards,
Martin

C# COM server events "lost" when raising events while Excel is in edit mode

I posted this question on StackOverflow (http://stackoverflow.com/questions/23798443/c-sharp-com-server-events-lost-when-raising-events-while-excel-is-in-edit-mode) but did not receive a good answer, so I'm trying my luck here.
I have an in-proc COM server written in C# (using .NET Framework 3.5) that raises COM events based on this example: http://msdn.microsoft.com/en-us/library/dd8bf0x3(v=vs.90).aspx
Excel VBA is the most common client of my COM server. I’ve found that when I raise COM events while Excel is in edit mode (e.g. a cell is being edited) the event is “lost”. Meaning, the VBA event handler is never called (even after the Excel
edit mode is finished) and the call to the C# event delegate passes through and fails silently with no exceptions being thrown. Do you know how I can detect this situation on my COM server? Or better still, make the event delegate call block until
Excel is out of edit mode?
I have tried:
Inspecting the properties of the event delegate – could not find any property to indicate that the event failed to be raised on the client.
Calling the event delegate directly from a worker thread and from the main thread – event not raised on the client, no exceptions thrown on the server.
Pushing the event delegate onto a worker thread’s Dispatcher and invoking it synchronously – event not raised on the client, no exceptions thrown on the server.
Pushing the event delegate onto the main thread’s Dispatcher and invoking it synchronously and asynchronously – event not raised on the client, no exceptions thrown on the server.
Checking the status code of the Dispatcher.BeginInvoke call (using DispatcherOperation.Status) – the status is always ends with “Completed”, and is never in “Aborted” state.
Creating an out-of-proc C# COM server exe and tested raising the events from there – same result, event handler never called, no exceptions.
Since I get no indication that the event was not raised on the client, I cannot handle this situation in my code.
I have tested this with Excel 2010 and Excel 2013.
Here is a simple test case. The C# COM server:
namespace ComServerTest
public delegate void EventOneDelegate();

Public WithEvents managerObj As ComServerTest.ManagerClass

Debug.Print "Done"
End Sub
' EventOne handler
Private Sub managerObj_EventOne()
Debug.Print "EventOne " & g_nCounter
g_nCounter = g_nCounter + 1
End Sub
This problem also occurs for a C++ MFC Automation server that raises COM events. If I raise the COM event from the main thread when Excel is in edit mode, the event handler is never called. No errors or exceptions are thrown on the server,
similar to my C# COM server. However, if I use the Global Interface Table to marshal the event sink interface from the main thread
back to the main thread, then invoking the event - it will block while Excel is in edit mode. (I also used COleMessageFilter to disable the busy dialog and not responding dialogs, otherwise I'd receive the exception:
RPC_E_CANTCALLOUT_INEXTERNALCALL It is illegal to call out while inside message filter.)
Knowing that, I tried to do the same on my C# COM server. I could instantiate the Global Interface Table (using the definition from pinvoke.net) and the message filter (using the IOleMessageFilter definition from MSDN). However, the event still
gets "lost" and does not block while Excel is in edit mode.
Here's my additional C# code to try to make use of the Global Interface Table:
namespace ComServerTest
// Global Interface Table definition from pinvoke.net
ComImport,
InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
Guid("00000146-0000-0000-C000-000000000046")
interface IGlobalInterfaceTable
uint RegisterInterfaceInGlobal(
[MarshalAs(UnmanagedType.IUnknown)] object pUnk,
[In] ref Guid riid);
void RevokeInterfaceFromGlobal(uint dwCookie);
[return: MarshalAs(UnmanagedType.IUnknown)]
object GetInterfaceFromGlobal(uint dwCookie, [In] ref Guid riid);
ComImport,
Guid("00000323-0000-0000-C000-000000000046") // CLSID_StdGlobalInterfaceTable
class StdGlobalInterfaceTable /* : IGlobalInterfaceTable */
public class ManagerClass : IManagerClass
//...skipped code already mentioned in earlier sample above...
//...also skipped the message filter code for brevity...
private Guid IID_IDispatch = new Guid("00020400-0000-0000-C000-000000000046");
private IGlobalInterfaceTable m_GIT = null;
public ManagerClass()
//...skipped code already mentioned in earlier sample above...
m_GIT = (IGlobalInterfaceTable)new StdGlobalInterfaceTable();
public void FireEventOne()
// Using the GIT to marshal the (event?) interface from the main thread back to the main thread (like the MFC Automation server).
// Should we be marshalling the ManagerEvents interface pointer instead? How do we get at it?
uint uCookie = m_GIT.RegisterInterfaceInGlobal(this, ref IID_IDispatch);
ManagerClass mgr = (ManagerClass)m_GIT.GetInterfaceFromGlobal(uCookie, ref IID_IDispatch);
mgr.EventOne(); // when Excel is in edit mode, event handler is never called and does not block, event is "lost"
m_GIT.RevokeInterfaceFromGlobal(uCookie);
I’d like my C# COM server to behave in a similar way to the MFC Automation server. Is this possible? I think I should be registering the ManagerEvents interface pointer in the GIT but I don't know how to get at it? I tried using Marshal.GetComInterfaceForObject(this,
typeof(ManagerEvents)) but that just throws an exception: System.InvalidCastException: Specified cast is not valid.
Thanks.

Hi Jason-F,
I’ve found that when I raise COM events while Excel is in edit mode (e.g. a cell is being edited) the event is “lost”. Meaning,
the VBA event handler is never called (even after the Excel edit mode is finished) and the call to the C# event delegate passes through and fails silently with no exceptions being thrown.
Do you mean you didn't raise EventOne event? EventOne handler like following?
' EventOne handler
Private Sub managerObj_EventOne()
Debug.Print "EventOne " & g_nCounter
g_nCounter = g_nCounter + 1
End Sub
After test your code, here is my screenshot
And here is my execute log in C# ComServerTest.

Sorry mate but you need a lot of work....
I like what you've done but (in my humble opinion) it needs a lot of reworking.
Your problem is you're not storing the shapes. You've set up an array but you never assign the shapes to it. I would reccomend using a vector. Heres a quick bit of pseudo code.
Listener class
mouseClicked method
if first click
get mouse x/y
if second click
get mouse x/y
create new MyShape(x1, y1, x2, y2)
call data.addShape(new MyShape)
Data class
constructor
this.myVector = new Vector()
addShape(MyShape shape) method
this.myVector.addElement(shape) -- add new shape
this.myVector.remove(0) -- remove bottom shape
drawAllShapes method
Enumeration enum= this.myVector.elements()
while(enum.hasMoreElements())
MyShape shape = (MyShape)enum.nextElement()
shape.draw()
Feel free to ask any questions.

I am trying to raise event at UserControl, and catch it at Main program, But the event always return null

I am trying to raise a event in one of classes of userControl, and Fire it in the Main class. I tried two different ways to fire this event, one of them works, But I still want to know why other way cannot work, and how to fix it.
My userContol class:
public partial class UserControl1 : UserControl
public UserControl1()
InitializeComponent();
if (System.ComponentModel.DesignerProperties.GetIsInDesignMode(this))
return;
Class1 c = new Class1();
Thread accept = new Thread(
() =>
c.connection();
accept.Start();
And the Class1:
public class Class1
public delegate void myhandler(object sender, EventArgs e);
public event myhandler test;
public Class1()
public void connection()
test(this, new EventArgs());
In the Main, I just simply add into referent, and add
xmlns:my="clr-namespace:WpfControlLibrary1;assembly=WpfControlLibrary1"
then I try to subscribe this event in the main
public partial class SurfaceWindow1 : SurfaceWindow
/// <summary>
/// Default constructor.
/// </summary>
public SurfaceWindow1()
InitializeComponent();
Class1 c = new Class1();
c.test+=new Class1.myhandler(c_test);
// Add handlers for window availability events
AddWindowAvailabilityHandlers();
public void c_test(object sender, EventArgs e)
MessageBox.Show("fire");
If I only raise this event not into thread, it works fine, but If I try to let it raise in this thread, this test event only return null, and shows:
Object reference not set to an instance of an object.
looks like I did not subscribe it ever. So How to fix it if I must use it in thread.

Subscribing to events window to class is not a great approach.
You have to then go un subscribe those handlers in order to allow your instance to be disposed.
Forget that and you'll eventually notice you have memory leaks.
The way I do this sort of thing is using mvvm light messenger.
You can keep everything decoupled then.
http://social.technet.microsoft.com/wiki/contents/articles/26070.aspx
I just did a bit of code for someone else which shows how to do cross thread stuff with this approach.
public partial class MainWindow : Window
public MainWindow()
InitializeComponent();
Messenger.Default.Register<String>(this, (action) => ReceiveString(action));
private void ReceiveString(string msg)
MessageBox.Show(msg);
Dispatcher.BeginInvoke((Action)delegate()
tb.Text = msg;
private void Button_Click(object sender, RoutedEventArgs e)
Task.Factory.StartNew(() => {
Messenger.Default.Send<String>("Hello World");
Note that the message arrives on the thread it was sent from. That's not the ui thread because it was sent from that task.factory.startnew to deliberately put it on a different thread.
In order to change UI controls, it uses dispatcher.begininvoke to run code on the UI thread.
Although this is in one piece of code behind publisher and subscriber can be in two totally different classes which have no reference of knowledge of each other.
Meaning you can send a message<t> from any class1 or whatever you like and your mainwindow can subscribe and act of receipt of a message<t>.
It is the type which defines which message one is. You put data you want to send in t and use it in the subscriber.
Hope that helps.

Switching touch events from symbols/classes to the main stage?

Bug ID #2940816
I have an app that wasn't compiling correctly. I sent the bug to Adobe who responded with a workaround. However, I can't figure out how to make their stated workaround work in my code.
I have puzzle pieces on the stage. Each is assigned to a separate class. Inside the class I have touch events defining multiple touch events for each piece.
I have another spot on the stage where, when it is touched, a puzzle piece appears. These are also each linked to a separate class. Inside this class I also have touch events defining multiple touch events for each piece.
Though it works fine on my computer, it wasn't working on an iPad. Adobe said that I needed to switch the touch events so that they were assigned to the main stage instead of to each individual object.
However, the code they gave me didn't really make sense in context and I'm confused how to implement it.
This is the code in the class for each piece that is created when you touch the stage:
        public function GeoPiece(): void {
            if (PuzzleGlobals.currentLevel == "Name") {
                this.gotoAndStop("wholeName");
            else if (PuzzleGlobals.currentLevel == "Abbrev") {
                this.gotoAndStop("abbrev");
            else if (PuzzleGlobals.currentLevel == "Shape") {
                this.gotoAndStop("shape");
            this.addEventListener(TouchEvent.TOUCH_MOVE, geoPieceBegin);
        public function geoPieceBegin (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = true;
            e.target.startTouchDrag(e.touchPointID, false);
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
            e.target.interactionBegin();
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(e.target.abbrev);
            PuzzleGlobals.currentPiece = e.target.abbrev;
        public function geoPieceEnd (e:TouchEvent): void {
            PuzzleGlobals.pieceActive = false;
            if (currentObjOver.isLocked == true) {
                currentObjOver.gotoAndStop ("Lock");
            else {
                currentObjOver.gotoAndStop ("Out");
            MovieClip(this.parent.parent).nameDisplay.gotoAndStop(PuzzleGlobals.chosenPuzzle);
            e.target.stopTouchDrag(e.touchPointID);
            if (this.dropTarget.parent is GeoPuzzle) {
                if (GeoPuzzle(this.dropTarget.parent).abbrev == e.target.abbrev) {
                    PuzzleGlobals.statesCompletedUSA++;
                    GeoPuzzle(this.dropTarget.parent).isLocked = true;
                    GeoPuzzle(this.dropTarget.parent).gotoAndStop("Lock");
                    e.target.parent.removeChild(DisplayObject(e.target));
                else {
                    //play BOOP sound indicated wrong drop;
            if (PuzzleGlobals.statesCompletedUSA == PuzzleGlobals.TOTAL_NUMBER_USA) {
                //play fireworks game
            else {
                //do nothing
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPieceEnd);
        public function interactionBegin () {
            if (this.dropTarget != null && this.dropTarget.parent is GeoPuzzle) { //check to make sure it's over a puzzle piece
                currentObjOver = GeoPuzzle(this.dropTarget.parent);
                currentObjOver.gotoAndStop("Over");
            if (lastObjOver != currentObjOver) {
                if (lastObjOver.isLocked == true) {
                    lastObjOver.gotoAndStop("Lock");
                else {
                    lastObjOver.gotoAndStop("Out");
                lastObjOver = currentObjOver;
This is the code in the class for each piece that's already on the stage:
        public function GeoPuzzle(): void {
            if (this.isLocked == true) {
                this.gotoAndStop ("Lock");
            if (PuzzleGlobals.pieceActive == true) {
                this.addEventListener(TouchEvent.TOUCH_BEGIN, geoPuzzleBegin);
        public function geoPuzzleBegin (e:TouchEvent): void {
            e.target.addEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
            e.target.gotoAndStop("Over");
            MovieClip(this.parent).nameDisplay.gotoAndStop(e.target.abbrev);
        public function geoPuzzleEnd (e:TouchEvent): void {
            if (e.target.isLocked == false) {
                e.target.gotoAndStop("Off");
            else if (e.target.isLocked == true) {
                e.target.gotoAndStop("Lock");
            MovieClip(this.parent).nameDisplay.gotoAndStop(PuzzleGlobals.chosenPuzzle);
            e.target.removeEventListener(TouchEvent.TOUCH_END, geoPuzzleEnd);
You can see that each piece (whether it's already locked on the stage or movable) reacts differently to different touch events. However, this is the code that Adobe gave me as a workaround:
this.stage.addEventListener(TouchEvent.TOUCH_BEGIN, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_MOVE, onTouchEvent);
this.stage.addEventListener(TouchEvent.TOUCH_END, onTouchEvent);
var beginCount:uint=0;
var moveCount:uint=0;
var endCount:uint=0;
function onTouchEvent(event:TouchEvent):void{
     switch (event.type){
          case TouchEvent.TOUCH_BEGIN:
                         trace("BEGIN")
                         beginCount++;
                         square.x = event.stageX;
                         square.y = event.stageY;
                         square.startTouchDrag(event.touchPointID, false);
                         break;
          case TouchEvent.TOUCH_MOVE:
                         trace("MOVE")
                         moveCount++;
                         break;
          case TouchEvent.TOUCH_END:
                         trace("END")
                         endCount++;
                         square.stopTouchDrag(event.touchPointID);
                         break;
     trace("begin: "+beginCount+" move: "+moveCount+" end: "+endCount);
//     countText.text = "begin: "+beginCount+" move: "+moveCount+" end: "+endCount;
This doesn't make any sense to me because it seems that it would only work if touching the stage had to react in just a single way. I have multiple pieces that need to each react differently.
1. The pieces that are locked to the stage need to highlight when touched and display their name.
2. These pieces also need to keep themselves highlighted and their names displayed when the touch is dragged off of them instead of just removed.
3. Each piece needs to be created when touching the Puzzle Piece button the stage. As these pieces are dragged, they need to highlight the pieces underneath them and unhighlight them when they are dragged off. They also need to display their own names, and lock into place when they are dragged over the correct piece.
My questions are:
1. Why don't touch events work in the compiler?
2. How can I translate my current working code's touch events to all be directly linked to the stage instead of their objects?
Thanks so much!

I am going to copy and paste this answer into all of the forums I've asked this question in case some noob like me comes along and needs the answer.
I found the problem! After 3 months I finally figured out what was wrong and why my app was working in Device Central when exported as Flash 10.1 and not on my iPad when exported as AIR for iOS.
The problem is that in the Flash runtime, if a line of code returns a bug, the flash runtime says "Error, shmerror, try again next time." So I had one if, else statement that was executing when it wasn't supposed to be - only once, at the very beginning of the program. It was throwing an error. When I exported as Flash, flash didn't care, and still executed the code later when it was supposed to. But Apple won't let their programs crash. So instead of just trying that code again, Apple decided, after the first error was thrown, that it would then COMPLETELY IGNORE that line of code. So the error was in the line where the states would unhighlight themselves. Apple just shut down that line of code, that's why it wouldn't execute properly.
I ended up changing this line of code
if (lastObjOver != null && lastObjOver.isLocked == true)
which threw an error when the piece was FIRST dragged over the puzzle, to to this
if (lastObjOver.parent != null && lastObjOver.isLocked == true)
which wouldn't throw the error.
Problem solved!
If anyone else is having this problem, I suggest you do what I did. Change all your touch events to mouse events so you can run the program in the adc debugger. That's when I discovered the error being thrown.

Need help with custom event from Main class to an unrelated class.

Hey guys,
I'm new to Flash and not great with OOP. I've made it pretty far with google and lurking, but I've been pulling my hair out on this problem for a day and everything I try throws an error or simply doesn't hit the listener.
I'm trying to get my Main class to send a custom event to an unrelated class called BigIcon. The rest of the code works fine, it's just the addEventListener and dispatchEvent that isn't working.
I've put in the relevant code in below. Let me know if anything else is needed to troubleshoot. Thank you!

Alright, this compiles, gives me no errors, shows my 'book' and 'flowers' icons perfectly when ran, and prints 'addEventListener' to the output window as expected. I get no errors when I press the button, 'dispatchEvent' is output (good), but the 'twitchUp' function is never called and 'EventTriggered' is never output.
How do I get the 'twitchUp' event to trigger?
