Question related to PO Event Handler

Hi Experts
I am facing issues related to PO Header Event Handler:
1. When I make change to Statistical Delivery Date under Delivery Schedule tab in ECC, The PO Header EH is getting deleted in EM. May I know the reason behind this? Please suggest how to avoid this.
2. When I am deleting one of PO Items, the PO Header EH is also getting deleted in EM. When I undelete the PO Item, my PO Item EH is active again but PO Header Eh is still in deleted status. Please suggest how to correct this.
I really appreciate your quick answers to this.
Regards
Ravi

Hi Steffen
When we tried to analyse through debugging, for the first issue, we found that the standard application tables PURCHASE_ORDER_HEADER_NEW and PURCHASE_ORDER_HEADER_OLD delivered by SAP for BPT ESC_PURORD, are not having the value D for DeleteVal. column. When we have put this manually for testing purpose, the issues are resolved. But we do not know the impact of putting this value here as standard SAP did not deliver it that way.
When we observed tables of other BPT, this value D is there. Please throw some light on this before we go ahead and make changes.
Thanks
Ravi

Question related to FILE SENDER handling of recordsets

Hi
We have a File->RFC SAP scenario
We are reading files using FTP File adapter. Splitting messages 100 messages per recordset. QOS is EXACTLY ONCE!
If we have a huge file - lets say 100.000 records.
The adapter starts reading and gets to 50.000th record and FTP server (SENDER) crashes.
My question is which one of the below scenarios is true (if any):
A)
are those 50.000 records now processed, and in "chunks" of 100's beeing routed to the SAP system and processed?
What then, if the FTP server comes up again, how does it know where in the file it has reached???
B)
Or is it so, that PI reads the file and persists the messages (in 100's) and only when it has reached the end of the file it then
starts to call the SAP system via RFC adapter.
If it does NOT reach the end of file (ie FTPserver crashes...) then ALL messages (so the 50.000) are marked as erronoeus and will NOT be processed to SAP RFC?
I hope it is B, but please help

Hi Bohamo,
Even if it is big file, all the records will be picked up at once (XI Picks one file at a time).
So even if the FTP crashes after you pick it up, then also XI will have all the 100000 records ready to be processed.
After the file adapter has the 1000000 records ready, then it will process chunks of 100 records each.
YOu will have one RFC call per 100 records of information (1000 RFC calls for the whole file).

Can File Based events Handle wildcards in the filename

The question was can file events handle wildcards in the filename? That way, the object scheduled to handle the event can query the file event specifics and process accordingly. The impact is that we will have to create a file event for every event type for every pathway/state. Therefore, in a worst case scenario, if there are 3 event types for every state, i.e., end of day, end of week, and end of month, and there are 50 pathways/states, then there would be 50 *3 or 150 total file events that would have to be entered. If BOE can handle file event wildcarding, then we need only one event.can we do that ???

Hi
As per my knowledge events will not Handle wildcards in the filename

Beginners Questions about Multiple JPanels in JFrame and event handling

I am a newbie with SWING, and even a newerbie in Event Handling. So here goes.
I am writing a maze program. I am placing a maze JPanel (MazePanel) at the center of a JFrame, and a JPanel of buttons (ButtonPanel) on the SOUTH pane. I want the buttons to be able to re-randomize the maze, solve the maze, and also ouput statistics (for percolation theory purposes). I have the backbone all done already, I am just creating the GUI now. I am just figuring out EventHandlers and such through the tutorials, but I have a question. I am adding an ActionListener to the buttons which are on the ButtonPanel which are on JFrame (SOUTH) Panel. But who do I make the ActionListener--Basically the one doing the work when the button is pressed. Do I make the JFrame the ActionListener or the MazePanel the ActionListener. I need something which has access to the maze data (the backbone), and which can call the Maze.randomize() function. I'm trying to make a good design and not just slop too.
Also I was wondering if I do this
JButton.addActionListener(MazePanel), and lets say public MazePanel implments ActionListenerdoesn't adding this whole big object to another object (namely the button actionlistener) seem really inefficient? And how does something that is nested in a JPanel on JFrame x get information from something nested in another JPanel on a JFrame x.
Basically how is the Buttons going to talk to the maze when the maze is so far away?

I'm not an expert, but here's what I'd do....
You already have your business logic (the Maze classes), you said. I'm assuming you have some kind of public interface to this business logic. I would create a new class like "MazeGui" that extends JFrame, and then create the GUI using this class. Add buttons and panels as needed to get it to look the way you want. Then for each button that does a specific thing, add an anonymous ActionListener class to it and put whatever code you need inside the ActionListener that accesses the business logic classes and does what it needs to.
This is the idea, though my code is totally unchecked and won't compile:
import deadseasquirrels.mazestuff.*;
public class MazeGui extends JFrame {
JPanel buttonPanel = new JPanel();
JPanel mazePanel = new JPanel();
JButton randomizeB = new JButton();
JButton solveB = new JButton();
JButton statsB = new JButton();
// create instanc(es) of your Maze business logic class(es)
myMaze = new MazeClass();
// add the components to the MazeGui content pane
Component cp = getContentPane();
cp.add(); // this doesn't do anything, but in your code you'd add
            // all of your components to the MazeGui's contentpane
randomizeB.addActionListener(new ActionListener {
    void actionPerformed() {
      Maze newMaze = myMaze.getRandomMazeLayout();
      mazePanel.setContents(newMaze); // this is not a real method!
                                      // it's just to give you the idea
                                      // of how to manipulate the JPanel
                                      // representing your Maze diagram,
                                      // you will probably be changing a
                                      // subcomponent of the JPanel
solveB.addActionListener(new ActionListener {
    void actionPerformed() {
      Solution mySolution = myMaze.getSolution();
      mazePanel.setContents(mySolution); // again, this is not a real
                                         // method but it shows you how
                                         // the ActionListener can
                                         // access your GUI
// repeat with any other buttons you need
public static void main(String[] args) {
    MazeGui mg = new MazeGui();
    mg.setVisible(true);
    // etc...
}

Question about event handling in JComponents

I have often found it useful to create a component that acts as an event handler for events the component generates itself. For example, a panel that listens for focus events that effect it and handle these events internally. (See below).
My question is: Can this practice cause synchronization issues or any other type of problem that I need to watch out for? Is it good/bad or neither. Are there any issues I should be aware of?
Thanks in advance for the help.
Example:
public class qPanel extends JPanel implements FocusListener
public qPanel () {
super.addFocusListener(this);
public void focusGained(FocusEvent e) {
//Do stuff
public void focusLost(FocusEvent e) {
//Do stuff
}

Hi,
Handling events this way is completely fine and saves on number of classes. Only thing you may want to watch out for is that the handler methods have to be public. This means that someone could use your component and call one of the methods. For example, I could write:
panel.focusGained(new FocusEvent(....))
when it's not really gaining focus. So, if you're writing this component for re-use you might want to be aware of this.
An alternative:
Use a single internal class to handle all events. It can then delegate to private methods of your component. Example:
class MyEventHandler implements FocusListener, MouseListener, etc... {
public void focusGained(FocusEvent fe) {
doFocusGained(fe);
public void mousePressed(MouseEvent me) {
doMousePressed(me);
Then your component could have:
private void doFocusGained(FocusEvent fe) {
private void doMousePressed(MouseEvent me) {
etc...
Just ideas :)
Thanks!

Question on program structure about event handling in nested JPanels in GUI

Hi All,
I'm currently writing a GUI app with a wizard included in the app. I have one class that acts as a template for each of the panels in the wizard. That class contains a JPanel called contentsPanel that I intend to put the specific contents into. I also want the panel contents to be modular so I have a couple of classes for different things, e.g. name and address panel, etc. these panels will contain checkboxes and the like that I want to event listeneres to watch out for. Whats the best way of implementing event handling for panel within panel structure? E.g for the the checkbox example,would it be a good idea to have an accessor method that returns the check book object from the innerclass/panel and use an addListener() method on the returned object in the top level class/panel. Or is it better to have the event listeners for those objects in the same class? I would appreciate some insight into this?
Regards!

MyMainClass.main(new String[] { "the", "arguments" });
// or, if you defined your main to use varags (i.e. as "public static void main(String... args)") then you can just use
MyMainClass.main("the", "arguments");But you should really extract your functionality out of the main method into meaningful classes and methods and just use those from both your console code and your GUI code.

Event handling question

I am very new to Swing....I am very confused about how event handling works. I created a button called "remove" and a list. When a user selects an item in the list and then clicks on the remove button, then the item should be deleted from the list. I am able to display the list and the button. I create a listener for the button in a separate class as follows:
class MyActionListener implements ActionListener
public void actionPerformed (ActionEvent e)
if(e.getActionCommand().equals("remove"))
{System.out.println("remove works");
Now my problem is ..how do i access the list in this class..because my list is set up in the other class (main class). Because if i try to do anything with the list in this class it shows the compile time error saying it cannot identify what list is. Please tell me how i can use the list in the MyActionListener class. Here is the code that sets up the list:
public abstract class VetNet extends JFrame implements ListSelectionListener
static DefaultListModel listM= new DefaultListModel();
static DefaultListModel listModel;
public static void main (String[] args)throws IOException
JPanel panel= new JPanel();
JLabel j=new JLabel("Welcome");
panel.add(j,BorderLayout.NORTH);
BufferedReader stdin=new BufferedReader(new InputStreamReader(System.in));
StringTokenizer reader;
reader=new StringTokenizer(stdin.readLine());
String first_name=reader.nextToken();
while(!first_name.equals("end"))
{ String last_name=reader.nextToken();
add_name(first_name,last_name);
reader=new StringTokenizer(stdin.readLine());
first_name=reader.nextToken();
}//while
DefaultListModel listModel=new DefaultListModel();
listModel=return_fname();
String first= (String)(listModel.firstElement());
JList sampleJList= new JList(listModel);
sampleJList.setVisibleRowCount(2);
// sampleJList.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
//sampleJList.setSelectedIndex(0);
//sampleJList.addListSelectionListener(sampleJList);
JScrollPane listPane=new JScrollPane(sampleJList);
panel.setBorder(BorderFactory.createEmptyBorder(60,60,30,60));
panel.add(listPane);
JButton b1=new JButton("add");
panel.add(b1);
JButton b2=new JButton("remove");
panel.add(b2);
JButton b3=new JButton("edit");
panel.add(b3);
JFrame frame = new JFrame ("VetNet");
frame.getContentPane().add(panel);
frame.addWindowListener(new WindowAdapter() {
     public void windowClosing (WindowEvent e) { System.exit(0); }
frame.pack ();
     frame.setVisible(true);
//MyActionListener myListener= new MyActionListener();
b1.addActionListener(new MyActionListener());
b2.addActionListener(new MyActionListener());
b3.addActionListener(new MyActionListener());
//sampleJList.addActionListener(new MyActionListener());
}//main
private static void add_name(String f_name, String l_name)
listM.addElement(l_name+ ", " + f_name);
}//method add_fname
private static DefaultListModel return_fname()
return listM;
}//method return_fname

Ok! This is the LONG answer, but I think you would benefit from reading it all.
Making something public means that it can be accessed from other classes; however, it must be accessed using an object(instance) of that class. This means, if I have a class MyJFrame that extends JFrame, then in another class, I can do this:
MyJFrame myFrame = new MyJFrame();
myFrame.dispose();
myFrame.isShowing = false;
Given that dispose() is a public method and isShowing is a public boolean variable that's in the MyJFrame object. Note: the opposite of public is private meaning that the variable/function is only accessible within the class. Also, in all my examples, I assume each class has access to the others.(in same Package, or imported)
There are times at which you do not want to call a function on a given object or you want variables that are defined in the CLASS context, not the OBJECT context. As in, I have the class MyJFrame, and I always want to be able to access every object(instance) of this class that I've created. I would accomplish this using a static variable. Define the variable the same place you would define any other variable of the class, but inclued the reserved word "static". As in:
public class MyJFrame{
public static Vector allFrames = new Vector();
then in my contructor, I would add this frame to the vector:
public MyFrame(){
allFrames.add(this);
Now that I have this set up, I can access all the frames I've made from anywhere using MyJFrame.allFrames (note that I use the CLASS name, and I don't have an instance of the object anywhere)
Another use of static is for functions. Going along with the same example, I could add a closeAllJFrames function:
public static void closeAllJFrames(){
for(int x=0; x<allFrames.size(); x++){
allFrames.elementAt(x).dispose();
then I can call this function from any other class using: MyJFrame.closeAllJFrames();
Also worth noting, this function could be placed in any other class(other than inner classes, which cannot have static functions), you'd just need to put MyJFrame. in front of the allFrames.
One last tip is: If you use code like I've shown, consider using a Hashtable instead of a Vector if you need to access certain frames(or whatevers) from afar. This will keep you from iterating thru the Vector and will decrease overhead significantly.
Hope this helps

UIX-XML BC4J Question regarding event handling

How can I use/access Application Module, defined in UIX-XML page (using <bc4j:registryDef>), in my event handler method ???

Sorry for the confusion. I figured out what you were asking.
The right way is this.
First, in your UIX XML page, declare your handler like this:
<event name="%myEvent%" >
<bc4j:findRootAppModule name="%ModuleName%" >
<method class="%eventclass%" method="%eventmethod%" />
</bc4j:findRootAppModule>
</event>
the strings in the % have to be replaced with your own particular names. %ModuleName% should be the same as the name of the module in the registry.
Then in the event handler %eventclass%.%eventmethod% you can use this to find the Application Module:
oracle.jbo.ApplicationModule mymodule
= oracle.cabo.data.servlet.bind.ServletBindingUtils.getApplicationModule(context);
"context" is passed in to your event handler as a BajaContext. ServletBindingUtils has several other methods for getting BC4J stuff, you should look at its definition.

Modify User Postprocess event handler

Hi All,
Can some one tell me how to fetch complete set of user data in orchestration while i trigger my update event handler.?
eg
I have a event handler which is working fine on create user operation.(populates a custom udf Country based on employee type and another filed called city)
Now in my update if i update my city country shd be updated,but orchestration only returns values for the fields which are updated and not all,my employee type is returned as NULL,which makes my code to fail
Can anyone tell me how to get the existing data in orchestration?
I hope I am able to explain my scenario
Thanks

Trajectory program event handling

Nobody else responded to my question on the subject "Trajectory" in Java Programming forum. See my post history for problem description and code. Perhaps the subject is more appropriate here as an event handling issue. Who has the technical savvy to attempt a solution?

(2) I wouldn't have problem with separate classes as
long as I have no inner classes and the program
essentially works. Sure, one 10,000 - line class may also work fine. However, it is reccommended do not make classes
(as well as source files) very large. The reason is that long file is more difficult to debug.
Second reason why i advised you to do that is that you mix in one class Trajectory (which is about 2000 lines long!!!) all - interface, event handling, calculations, parts responsible for 2D panel processing....
Well, this is not Java is supoposed to be used for.
(3) Creating object of class Falling object is
something I'll consider. If you could show me a brief
code example, I'll understand more.
class fallingObject
      private double mass;
      private double speed;
      Position[] trajectory = new Position[1000]; // Create class Position each object of which holds only
      // 2 variables - x and y
     //all initial data related to this object
     fallingObject(double mass, double speed , /* the rest ........*/)
          this.mass = mass;
           this.speed = speed;
          moveObject();
          //and so on
    // some methods you need
     private moveObject ()
         // perform all calculations
         // fill array
     // etc
Now, because all except trajectory array and constructor is private you cannot change this object outside
class. This means that if something goes wrong with calculations, you check only this class and nothing else. In your case you can change some variable at lines 1352 and 122 - you have to check all program to find bug. Here you have to check only this class.
You may also supply this class with mutators and accessors
public double getMass()
   return mass;
public void setMass(double mass) // only if you really need this
   this.mass = mass;
The time interval
is a tricky parameter since not all calculations work
properly with input data; check input
the logic would require more
complexity and possibly cause run time problems;
automatically testing for the appropriate time
interval could also reduce program efficiency. Dont think so. You can calculate time of falling and divide it by 1000, for instance.
It will take very short time.
I don't
want to set a limit for array points to 1000 or less
since the precision becomes limited and the power of
the program can be hurt severely since the time
duration would be restricted to less than 16 2/3
minutes( 1 second per array index increment). Dont use real time simulation. There is no sence in it. You just want to show how object is falling.
Also, I
don't think the array size can't be changed during a
program run although I have set a much higher maximum
value for array size. Theres no need to change array size.
(4) Erasing data from textfields is something I desire
as a calculation reset feature since it should signal
user that it expects new data and not looking at old
data; however, I might consider additional variables
to hold the data. Well, man, it was quite irritating to type them in. So many fields. User is not stupid,
he knows that he can input other data. Almost anybody will leave this page and wont want to
fill fields again. You have to think about user, not about what you want.
(5 )BTW, what I have in the array doesn't have the
same precision as with the calculation mode. The 2D
simulation uses less precise data to become visually
practical for comprehension of users. But perhaps I
need more than one type of array, but then again,
performance could be a problem.
(6) I thought the program already does take parameters
from text fields and start again. This is what I
desire anyway so I'm not sure why I need new start
feature.
(7) Restart animation seems unaccepatble since I
prefer to treat each simulation as something based on
new calculation data.
I would have initially set up the program with OOD
emphasis, but the original intent was a java
conversion of a a C++ program that needed only a
structured program design and the conversion worked
fine. This Java program has evolved with the 2D
simulation enhancements.
When you did testing the other day, did you use
appletviewer? I looked at it on your site using Safari and run it as application also.
Appletviewer will not detect the problem
so don't rely on Appletviewer to interpret the
problem. Oddly, I wish the program behaved the same
way as what happens when using appletviewer. In fact,
if I could change 2d reset button logic to terminate
and restart the entire applet again via html, then my
problem would be solved. But I don't know if this type
of applet restart is possible or how to effect the
code change if feasible.

Java 1 vs. Java 2 Event Handling

Prelude: This question relates to writing code for event handling.
Java 1 is based on a hierarchy model to handle events, ie. inheritance from superclasses. Java 2 uses delagation event handling method. Java 2 code will not compile if it includes Java 1 code still modeled according to Java 1 event handling.
Question:
Is it generally easier to start completely over in trying to convert Java 1 code into Java 2 code by not retaining any Java 1 code and begin reconceptualizing what is needed for a conversion to Java 2?

From what I understand java2 should support both models, however not both at the same time, you cant mix the modles...
I also think that the older models methods or at least most have been depreciated, meaning that the old model will, if it hasnt allready in the latest release, dissapear.. For that single reason I would recommend updating the event model to the delegation model if you hope to keep it around and running for years to come. You gain a bit by doing this since the newer model is much faster!!!

Multiple event-handling threads?

I am writing a Java program that will launch other Java programs within the same JVM. This feature is for an RAD IDE that currently uses Runtime.exec.
The main problem is that the launcher is an IDE that will try to launch Swing applications within the same JVM. If a badly-written program traps the event-handling thread, it will bring the whole IDE down. The IDE's "Kill" button wont even work.
Is there any way to tell the JVM to use different event-handling threads for my application? Alternatively, does anybody know of any obscure functions I could use to maybe cause the event-handling thread to delegate processing to another one of my own threads? Ugly hacks are welcome.

After I first posted this question, I've taken a look at the java.awt.EventQueue class. The API provides an easy way to use your own EventQueue that could possibly dispatch events with multiple threads. If you make sure that you only use one thread at a time for each virtual JVM, I don't think that there will be any thread issues (unless there are any assumptions in AWT/Swing code about there only being one thread).
About the load time being 0.5 seconds. I'm sure it'll improve, but a failed load only loads and links a minimum number of classes. I wrote a program that runs the java compiler from com.sun.tools.javac.Main and it looks like the load time is about 1.75 seconds. Since the compile time itself is usually under a second for around 2000 lines of code, this kind of makes a difference (500MHz P3, by the way). This load time will probably be even greater for Swing applications.
When you're lauching a big program it may not matter much but the load time really kills Java's ability to create a quick command-line tool (not that it's best-suited for such a tool anyway, but it would be nice to have that barrier removed).
The biggest problem with creating a lightweight JVM right now is probably the stupid File class. Even if you change "user.dir" in the system properties, many File methods still resolve relative to the original "user.dir". Though many other problems exist, this is the one that really kills it because of the pervasiveness of the File class.

Javascript embedded in button pl/sql event handler not being executed

Javascript calls not working from pl/sql button event handler. What am I missing? Are specific settings needed to execute javascript from pl/sql proceedures?
Example: Want to toggle target='_blank' off and on in a button pl/sql event handler to open url call in new window & then reset when processing submit is done & the app returns to the form.
portal form button's pl/sql submit handler:
begin
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
htp.p('<script language=JavaScript>') ;
htp.p('this.form.target="_blank"') ;
htp.p('</script>') ;
end ;
Putting the following in the button's javascript on_click event handler works great:
this.form.target='_blank'
to force opening new window with a call in the button's submit pl/sql code via:
PORTAL.wwa_app_module.set_target('http://www.oracle.com') ;
but then the target='_blank' is left on when the submit is done & we return to the form.
putting the above javascript as a function (called fcn_newpage) elsewhere (e.g., after form opens) & calling in the submit pl/sql with
htp.p('fcn_newpage') ;
also doesn't work.
Metalink thought this was an application issue instead of a bug, so thought I'd see if anyone knows what's going wrong here. (Portal 9.0.4.1)

thanks for your discussion of my post.
Please clarify:
"htp.p('fcn_newwindow') sends a string":
What would you suggest the proper syntax for a function fcn_newwindow() call from a pl/sql javascript block that differs from
htp.p('<script language="Javascript">') ;
htp.p('fcn_newwindow');
htp.p('</script>');
or more simply
htp.p('fcn_newwindow') ;
More generally, what I'm trying to figure out is under what conditions javascript is executed, if ever, in the pl/sql of a button (either the submit or custom event handler, depending on the button).
I've seen lots of posts asking how to do a simple htp.p('alert("THIS IS TROUBLE")') ; in a pl/sql event handler for a button on a form, but no description of how this can be done successfully.
In addition to alerts, in my case, I'd like to call a javascript fcn from a pl/sql event handle that would pass a URL (e.g., http://www.oracle.com) where the javascript fcn executed
window.open(URL). The API call to set_target(URL) in pl/sql has no ability to open in a new window, so calling that is inadequate to my needs and I must resort to javascript.
Its clear in the PL/SQL of a button, you can effect form components since p_session..set_target & p_session.get_target set or get the contents of form components.
So to see if javascript ever works, I tried to focus on something simple that only had to set what amounts to an enviromental variable when we returned to the form after a post. I chose to try to change the html value of TARGET from javascript in the PL/SQL button because it doesn't need to be implemented until we finish the post and return to the form.
So I focused on a hack, setting this.form.TARGET='_blank' in the on_click event handler that forced every subsequent URL call or refresh of the form to be a new window. I then wanted to turn off opening new windows once I'd opened the URL call in a new window by setting TARGET='' in the portal form. I can achieve what I want by coding this.form.TARGET='' in the javascript (on_focus, on_change, or on_mousedown, ...) of every form component that might refresh the form. However, that is a ridiculous hack when a simple htp.p('<script>') ; htp.p('this.form.target=""') ; htp.p('</script>') ; at the end of the button's pl/sql event handle should do the same thing reliably if javascript ever works in the pl/sql event handler.
If we didn't have access to form components through p_session calls, I'd assume it was a scope issue (what is available from the pl/sql event handler). But unless my syntax is just off, when, if ever, can javascript be used in a portal form's pl/sql event handler for a button?
if I code a javascript funtion in the forms' pl/sql before displaying form:
htp.p('<script language="JavaScript">') ;
htp.p('function fcn_new_window(URL)') ;
htp.p('window.open(URL)' ) ;
htp.p('</script>') ;
the function can be called from a button's on_click javascript event handler:
fcn_new_window('http://www.oracle.com')
but from the same button's pl/sql submit event handler this call doesn't work: htp.p('fcn_new_window("http://www.oracle.com")')
So my questions remain: Is there other syntax I need, or does javascript ever work properly from the pl/sql of a form button's event handler? If it doesn't work, isn't this a bug that should be fixed by Oracle?
I can probably figure out hacks to make things work the way I need, but executing javascript from pl/sql event handlers seems to be the expected way to affect portal html pages (forms, reports, ...) and it seems not to work as expected. I don't feel I should have to implement hacks for something as simple as calling a javascript function from pl/sql when almost every example I've found in metalink or the forums or Oracle Press's "portal bible" suggests using javascript from pl/sql via the utility htp.p() to effect web page components in portal.
My TAR on the subject, while still open, returned the result basically: "We can reproduce your situation. Everything looks okay to us, but we can't explain how to use javascript where you want or point you to any documentation that would solve your problem or expain why it should not work the way you want it to. We don't feel its a technical issue. Why don't you post the problem on the portal applications forum."
I'm hoping I'm just missing something fundamental and everything will work if I implement it a little differently. So if anyone sees my error, please let me know.
by the way, not sure this is germain, but in reference to your comment:
"redirections in pl/sql procedures give a peculiar result. in a pl/sql procedure, usually, portals give the last redirection statement and ignore anything else coming after it."
if I try to raise an alert:
htp.p('alert("you screwed up")');
return;
in a pl/sql event handler, it still doesn't raise the alert, even though its the last thing implemented in the event handler. But if I set the value of a text box using p_session..set_value_as_string() at the same spot, it correctly sets the text box value when I return to the form.

OIM 11.1.1.5: Post Process Event Handler, change password notification

Hi,
Products
OIM 11.1.1.5 BP02
OAM 11.1.1.5
OID 11.1.1.5
Problem
I have written a post-process event handler which fires when a role is assigned to a user. The event handler calls a plugin which uses the UserManager API to generate and change the user's password.
I've tested this by assigning a role to the user via the OIM web console. I can see my log messages indicating that the event handler has fired and that the password has been changed.
However, I expected that when UserManager.changePassword completed, a notification email would then be sent to the user informing them of the new password, but no notification email has been sent.
The email notifications have been set up correctly, because I have changed the same user's password via the OIM web console and successfully received a Reset Password email.
So, my questions are:
1) Am I right in thinking that when you call UserManager.changePassword(), an out-of-the-box ResetPassword email notification should be sent to the user?
2) Has anyone got this working in 11.1.1.5?
Some more detailed info
In my plugin class I'm calling the following from both execute methods (EventResult and BulkEventResult):
char newpasswd[] = new RandomPasswordGeneratorImpl().generatePassword(user);
getUserManager().changePassword(userKey, newpasswd, false, null, true);
logger.info(("Successfully changed password"));

No notification will be sent if you changepassword using the method from usermanager api.
You have to trigger the resetpassword event manullay in your code.
Here is a sample code to create an event for reset password. Once you create event, invoke it from notification service - notify method.
NotificationEvent event = new NotificationEvent();
String[] receiverUserIds= {userLogin};
event.setUserIds(receiverUserIds);
event.setTemplateName("ResetPasswordNotification");
event.setSender(null);
HashMap<String, Object> resolvedData = new HashMap<String, Object>();
resolvedData.put("userLoginId", userLogin);
event.setParams(resolvedData);

Event handling in LOV

Hi There,
We have a use-case where we need intercept the event of af:inputComboboxListOfValues component.
I have table, which has three columns, Name, Description and Label.
I have a LOV on Name column.
When user change the value of Name column by selecting an value from dropdown, I need to do business validation, I show user the "Yes/No" popup with warning message, and base on the user's choice, either proceed with the change or stop the change.
My problem is that I am unable to find a appropriate event to show the popup.
I know there are several events in the af:inputComboboxListOfValues component, launchPopupEvent, returnPopupEvent and valueChangeEvent.
1. If I show popup on launchPopupEvent, after the user click "Yes/No" button on the popup, the page will be refreshed and dropdwon doesn't show the item list.
2. returnPopupEvent and valueChangeEvent event will be handled by framework in one request, there is no chance for user's interaction.
I am not familiar with ADF event handling machenism, can anyone help me?
Thanks in advance.
Thunder

Hi,
first of all, never post questions regarding internal JDeveloper builds (11.1.1.7 is not released to public) on this public forum. You are from Oracle and therefore have internal channels for this (note that using internal builds the problem could be with the build and not necessarily the code alone).
To your question:
I don't understand why
+"2. returnPopupEvent and valueChangeEvent event will be handled by framework in one request, there is no chance for user's interaction."+
doesn't work. If you set the "name" column component to autosubmit="true" then the listener fires as soon as you move out of the field and you can raise the alert. The current row in the binding points to the row you changed the name for and as such the value can be unset (the value change listener shows you the before and after value)
