Help with Event Handlers with Scope

I have a question of how I must implement the event handlers with scope, I have problems in the execution of processes BPEL (they are generating exceptions in the dehydration)
I have two models for event handlers and I need to know which is the best way to implement event handlers.
Another question is, in what it influences the "variableAccessSerializable" attribute.
Thanks!
1) Event Handlers with PartnerLink invocation OUTSIDE Scope
<invoke name="Invoke_1" partnerLink="PartnerLink1"/>
<scope name="Scope_1" variableAccessSerializable="yes">
<eventHandlers>
<onMessage partnerLink="PartnerLink1"/>
<onAlarm/>
</eventHandlers>
<sequence name="Sequence_1">
</sequence>
</scope>
2) Event Handler with PartnerLink invocation INSIDE scope
<scope name="Scope_1" variableAccessSerializable="yes">
<eventHandlers>
<onMessage partnerLink="PartnerLink1"/>
<onAlarm/>
</eventHandlers>
<sequence name="Sequence_1">
<invoke name="Invoke_1" partnerLink="PartnerLink1"/>
</sequence>
</scope>

Thanks -- indeed a crucial call might be missing. I was doing
this until 3 yesterday morning.
Would this be the correct sample code to use? :
http://livedocs.macromedia.com/flash/mx2004/main_7_2/wwhelp/wwhimpl/common/html/wwhelp.htm ?context=Flash_MX_2004&file=00000846.html
It seems to work (although someone cautions in the page
comments that it doesn't).
Part of my trouble in working with AS 2.0 is that I feel I
shouldn't have to do such complicated things (Delegate classes,
etc) in order to get simple things done (loading XML files). This
is not a complaint per se -- rather I feel that I must be missing
something, that it is my inexperience that is causing me to bend
through so many hoops: programming "should" be elegant and simple.
So, any links helpful. Thanks.

OIM11g - Event handlers - picking up external libraries

Hi all,
I seem to be running into an issue with event handlers. I have to refer to some other custom libraries within them and they don't seem to be accessible by the event handlers.
I've put the libraries in JavaTasks and ThirdParty but I'm still getting NoClassDef found and in the worst case the Orcherstration engine seems to break preventing me from even logging into OIM and meaning I have to remove the event handler metadata manually.
Does anyone know how the event handler classpath works and where I can put libs such that event handlers can use them?
Thanks.
Wayne.

From the WebLogic Administrator screen, you can go to the servers for your OIM Server, or SOA Server, whichever will be accessing the jar. Under the server start tab, add in the path in the classpath section for your jar file. User forward slashes. Now when your server starts, it will load those jar files and they should be accessible.

ALV Grid event handlers

Hello Friends;
I have a problem with event handlers. I have defined events for double_click, data_change and hotspot_click. At first run of the program everything runs fine but when I make a change at the screen (like pressing Enter or entering a value at a screen field) the handlers seem to be called a couple of times. For example at a hotspot click I call an accounting document display and when I want to return with back button the program seems to be stuck at document display. Actually it calls event handler over and over again. How can I solve this problem? Can refreshing grid be a solution?
Thx in advance
Ali

Hello Ali
The problem is that after handling the hotspot event the current cell is still on the field with the hotspot. Thus, when you push ENTER the ALV grid checks the current cell which has a hotspot defined which, in turn, raises event HOTSPOT_CLICK.
Therefore, you have to move the current cell to another cell that has no hotspot defined. Have a look at the implementation of the event handler method. The hotspot is on field KUNNR. After calling transaction XD03 I shift the current cell to field BUKRS.
If you comment these lines you will see the same behaviour of the report as you described.

Event handlers in a template file in uix

Is it possible to define event handlers in a uix template file. I would like to define a global button kind of like the following code:
<globalButton source="toolbar_icon_prefs.gif" text="My Profile"
destination="UsersMyProfile_View.uix" event="event1" />
I would probably remove the destination field and let the java program called by the event decide the destination.
The event handler would need to not interfer with event handlers defined on individual pages.
Thanks, Steve

Sorry, Steve, but event handlers are not supported in templates.

I need help with event structure. I am trying to feed the index of the array, the index can vary from 0 to 7. Based on the logic ouput of a comparison, the index buffer should increment ?

I need help with event structure.
I am trying to feed the index of the array, the index number can vary from 0 to 7.
Based on the logic ouput of a comparison, the index buffer should increment
or decrement every time the output of comparsion changes(event change). I guess I need to use event structure?
(My event code doesn't execute when there is an event at its input /comparator changes its boolean state.
Anyone coded on similar lines? Any ideas appreciated.
Thanks in advance!

You don't need an Event Structure, a simple State Machine would be more appropriate.
There are many examples of State Machines within this forum.

Need help with EVENT BOOKING: option for multiple, payment (pay pal standard or pro only) add cost, etc

Hello!
I'm at my wits end: please help! It seems straight forward, and I sold my client on BC thinking this was doable in the events module, but it seems maybe not so without a ton of custom coding.
1. Book an event online,
with option for multiple (say 1-5 people at a fixed cost per person),
and checkout using only Pay Pal (standard or pro, doesn't matter, but I think Standard won't work without shopping cart).
2. The events are every day but Sunday all year long (just admission to an attraction), so is there a way to upload months in advance so they don't have to be manually entered?
I'm so grateful for any assistance.

This is all very achievable:
• Events you can add multiple people to book.
• PayPal you use use our APP that's in the BC Appstore (Liam to confirm is works with bookings)
I'm sales and marketing at Pretty, so I'm not the person to advise on how all this fits together. But I'm sure Liam can point you in the right direction.
If you need some consulting or us to do it for you just let me know [email protected]

Problems with .chart-plot-background and event handlers

Hello. I'm trying to add event handlers to my chart so that the user can be allowed click within the chart itself to perform certain actions like dragging, zooming, etc. To avoid having to deal with handling mouse clicks that lie outside the chart itself (for example on the axes), I've found that:
.chart-plot-background
is the Region that gives me the entire chart and nothing else. However, when I attach mouse listeners to this Region, the event is only registered on half of the cells in the chart. If you've seen the default JavaFX Chart background layout, you know that it contains alternating rows of cells with slightly different coloring. I've found that only the rows with the lightest gray coloring actually register a mouse click on them, which makes me believe the dark grey cells are not part of the .chart-plot-background, but something else on top.
To me, this feels like an oversight in how the regions of the chart are defined. Why can I not get a listener to work on the whole chart and nothing else? Currently the only workaround seems to be to take the Region:
.chart-content
instead, and compute the difference between this region and the .chart-plot-background in order to manually suppress mouse clicks that lie outside .chart-plot-background.
Anyone have suggestions? Is this worth issuing on the JavaFX Jira?

Hello,
I'm not an expert on controls, but here is my guess based on your description: when you register an event handler on a "background" node, it is called only when the mouse hovers over the background node - I suppose the light gray is the background with the light gray cells being transparent and dark grey cells being filled. So the behavior seems correct - you can't expect the events to be delivered to background when it is covered by other nodes. I think you really should register the handler on the entire chart and filter out the events you don't want to handle. This however should not require much of computing the difference between the regions, it should be possible to do just something like
if (!background.contains(event.getX(), event.getY())) {
return;
Provided that the background doesn't reach under the axes as well. Note that if there are any different transforms between the background and the node with the handler registered on it, you may need to recompute the coordinates by
background.sceneToLocal(event.getSceneX(), event.getSceneY());
And use the contains method on that.

Event Handlers which trigger functions with multiple arguments

I am playing two video clips back to back. I have a few
things which I need to do in between clips, so what I am doing for
each is adding a handler for VideoEvent.COMPLETE, at which time i
want to call a function which takes multiple arguments, like this:
video.addEventListener(VideoEvent.COMPLETE,
myFunction("1","2","3"));
private function myFunction(var1:String, var2:String,
var3:String):void
video.removeEventListeners(VideoEvent.COMPLETE, myFunction);
I've already figured out that getting rid of event handlers
that trigger anonymous functions is impossible. Please don't tell
me that it's impossible to remove them if functions require more
than 0 arguments...

Any function that you add via addEventListener should expect
exactly ONE
argument, the event. And 99.958% of the time, you can take
that event
object and figure out exactly what you need to know.

Need Help with Event Handler Code - Doesnt come up in Event Handler Manager

Hello there,
Below is the code snippet that I am using to create a event handler:
package com.oracle.events;
import com.thortech.util.logging.Logger;
import com.thortech.xl.client.events.tcBaseEvent;
import com.thortech.xl.dataobj.tcDataObj;
import com.thortech.xl.util.logging.LoggerModules;
public class tcCheckOvrallProvStatusUDFs extends tcBaseEvent
     private static Logger logger = Logger.getLogger(LoggerModules.XL_JAVA_CLIENT);
     public tcCheckOvrallProvStatusUDFs()
          setEventName("Generating tcCheckOvrallProvStatusUDFs");
* @Override
* @throws Exception
     protected void implementation() throws Exception {
          tcDataObj data = getDataObject();
          String OIDProvStatus = data.getString("usr_udf_oidusrprovstatus");
String EBSProvStatus = data.getString("usr_udf_ebstcausrprovstatus");
          if (OIDProvStatus.equals("Provisioned") && EBSProvStatus.equals("Provisioned")) {
               setOverAllProvStatus(data);
     * @param data
     * @throws Exception
     private void setOverAllProvStatus(tcDataObj data) throws Exception
          data.setString("usr_udf_ovrrscprovstatus", "Provisioned");
Its a simple code that I am using to populate value of a UDF field depending on the value of other 2 fields. I want to trigger it on Post-Insert and Post-Update events.
But even if I restart the OIM server after placing the successfully compiled file (0 errors, 0 warnings) into the EventHandlers folder of OIM_HOME; it doesnt show up in the Design Console -> Development Tools -> Business Rule Definition -> Event Handler Manager. :( In order to create a event handler i need that file to show up in the lookup of event handlers/adapters. This JAR file doesnt come up over there.
Is there anything missing within the code ?
What else needs to be specified?
Please provide some guidance.
Thanks,

OK, so you've got this code here:

public void actionPerformed (ActionEvent e) {
    if (e.getSource () == exit) {
      System.exit(0); // exits the GUI
    if (e.getSource () == snam) {
    if (e.getSource () == id) {
}Perfect fine way to do this; although I think creating anonymous would be a bit cleaner:
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
});But I think that the real question you have is "what do I put for logic when the JButtons are hit?", right?
I would answer that you want to dynamically build your SQL statement changing your ordering based on the button.
So you'd have a method that builds the SQL based on what you pass in - so it takes one argument perhaps?
private static final int NAME = 1;
                         ID = 2;
/* ... some code ... */
snam.addActionListener(new actionListener() {
public void actionPerformed(ActionEvent ae) {
    buildSQL(NAME);
/* ... some code ... */
private void buildSQL(int type) {
if ( type == NAME ) {
/* ... build SQL by name ... */
else if ( type == ID ) {
/* ... build SQL by id ... */
}That kind of thing.
Or you might choose to have several build methods with no parameter type; each building the SQL differently, and calling whichever one you need. I did not read your entire pgm, so I don't know how you'd want to organize it. You need to ask more specific questions at that point.

Having an issue with event handling - sql database & java gui

HI all, have posted this on another forum but I think this is the correct one to post on. I am trying to construct this hybrid of java and mysql. the data comes from a mysql database and I want it to display in the gui. this I have achieved thus far. However I have buttons that sort by surname, first name, ID tag etc....I need event handlers for these buttons but am quite unsure as to how to do it. any help would be much appreciated. Thanks in advance.

Events problem with (Java and ActiveX)

Hi,
I use an ActiveX component with Java and i've got a problem with events.
Java classes were generated with Bridge2Java (IBM).
In order to manage events I added a listener in my application :
javaMyActiveX = new MyActiveX();
javaMyActiveX.add_DMyActiveXEventsListener(new _DMyActiveXEventsAdapter());
I also added a constructor in the _DMyActiveXEventsAdapter class and I fill the body of methods.
The ActiveX generates two types of events :
- The ones are directly generated by methods.
- The others are generated by a thread.
With MS Products (VB, Visual C++, Visual J++), I catch all events.
With java (jdk 1.4), I catch only events generated by methods.
Can anyone help me.

I'm not 100% sure, but the last time I used that bridge, it only worked if you ran your Java app within a Microsoft VM.

Problem with event handling

Hello all,
I have a problem with event handling. I have two buttons in my GUI application with the same name.They are instance variables of two different objects of the same class and are put together in the one GUI.And their actionlisteners are registered with the same GUI. How can I differentiate between these two buttons?
To be more eloborate here is a basic definition of my classes
class SystemPanel{
         SystemPanel(FTP ftp){ app = ftp};
         FTP app;
         private JButton b = new JButton("ChgDir");
        b.addActionListener(app);
class FTP extends JFrame implements ActionListener{
           SystemPanel rem = new SystemPanel(this);
           SystemPanel loc = new SystemPanel(this);
           FTP(){
                   add(rem);
                   add(loc);
                   pack();
                   show();
       void actionPerformed(ActionEvent evt){
        /*HOW WILL I BE ABLE TO KNOW WHICH BUTTON WAS PRESSED AS THEY
           BOTH HAVE SAME ID AND getSouce() ?
           In this case..it if was from rem or loc ?
} It would be really helpful if anyone could help me in this regard..
Thanks
Hari Vigensh

Hi levi,
Thankx..
I solved the problem ..using same concept but in a different way..
One thing i wanted to make clear is that the two buttons are in the SAME CLASS and i am forming 2 different objects of the SAME class and then putting them in a GUI.THERE IS NO b and C. there is just two instances of b which belong to the SAME CLASS..
So the code
private JButton b = new JButton("ChgDir");
b.setActionCommand ("1");
wont work as both the instances would have the label "ChgDir" and have setActionCommand set to 1!!!!
Actually I have an array of buttons..So I solved the prob by writting a function caled setActionCmdRemote that would just set the action commands of one object of the class differently ..here is the code
public void setActionCommandsRemote()
     for(int i = 0 ; i <cmdButtons.length ; i++)
     cmdButtons.setActionCommand((cmdButtons[i].getText())+"Rem");
This just adds "rem" to the existing Actioncommand and i check it as folows in my actionperformed method
     if(button.getActionCommand().equals("DeleteRem") )
                    deleteFileRemote();
      else if(button.getActionCommand().equals("Delete") )
                 deleteFileLocal();Anyway thanx a milion for your help..this was my first posting and I was glad to get a prompt reply!!!
