GetNext() of Disassemble Stage is executing two time

why GetNext() of Disassemble Stage is executing two times ?I checked it in event log.
Prakash

GetNext method returns all the messages created out of Disassemple method.
Returned message it passed to next pipeline stage or message box as configured. GetNext method is called repeatedly as long as it returns some IBaseMessage type. Repeated calls stop only when
GetNext returns null.
So, the second call is when the
GetNext returns null for you.

        vo.insertRow(row);
        row.setNewRowState(row.STATUS_INITIALIZED);
Please help me out.

hi,
PR() will be called whenever your page will load, so the number of times you will load your page all the time your PR will be called and it will call the AM method.
otherwise put some condition and call the insert method from your PR.

WDDOINIT method executes every time when returning to View

We are making Enhancements to the Travel Expense WDA. (Package: PTRM_WEB_UI)
When creating a New Expense Report, the WDDOINIT method is being executed only once each time the View is displayed. This is what is expected.
When changing an existing Expense Report, the WDDOINIT method is being executed each time the view is displayed.
The Lifetime Property of all of the views are set to "framework controlled". It seems like when in change mode, the lifetime property of the views is acting as if they were set to "when visible".
Is there some way that this property is being dynamically changed when in change mode? Does anyone know if SAP intended the Travel Expense WDA to act this way when in change mode?
Any help or insight regarding this issue would be helpful.
Thanks,
Aaron

It could be that there are multiple component usages and that this view belongs to an inner component. The parent component could call DELTE_COMPONENT on the component usage if no views from that componet are currently visibile. This is done for memory manage as there is no garbage collection of compoonent instances at runtime. This would have the effect that the WDDOINIT would be called again if the component is used again/the view is reshown. I have seen complex internal applications that use separate components for each tab for instance. When the tab switch occurs, they perform a DELTEE_COMPONENT. This can have a significant positive impact on the memory consumption of the session. This could explain the behaviour you are seeing.

ListSelection Listener is executing two times

Hi,
I am using my own cell renderer for the JList and adding some buttons in the JList.I am adding ListSelectionListener to my JList.When i am selecting a item in the JList, the listselection event is fired two times.How should i rectify this.

I've had the same problem, and I solved it by by asking my ListSelectionEvent's getValueIsAdjusting() method:
rowTypeSM.addListSelectionListener(new AbstractListSelectionListener(){
public void doValueChanged(ListSelectionEvent e){
if(!e.getValueIsAdjusting()){
// Stick your code here
Hope this helps.

Oracle native sequencing: nextVal executed two times.

We are migrating from Weblogic 6.1 sp 5 & TopLink 3.6.3 to Weblogic 8.1 sp 2 & TopLink 9.0.4 and we are having this issue:
It seems that when assigning the sequence to new objets TopLink execs the nextVal for the sequence twice. In fact we probably wouldn't notticed it if it was just that, the problem is that TopLink seems to register the object into the cache with an oid and assigning the next one to the object stored in the database so we are getting NoSuchObjectException each time we try to access them.
Here is a dump of TopLink's log showing the problem:

the test is about creating two objects (well, we are actually creating 6 objects in this sample as we are creating two "master" objects and adding two related (in a one to many relationship) objects to each one.)
The thing I would like you to notice is this:
The first AUTHOR object gets assigned the OID 442803 wether the next AUTHOR object gets the OID 442805 although we expected it to be 442804.
The same occurs with the objects in the "many" side of the relation. They get sibiling OIDs but with a gap of two OIDs when creating the last two.
I have been searching for simmilar problems in this forums and I found two posts:
Both where related to a bug of an older version of TopLink (9.0.3 I think) when using something different than a number for the sequence field of an object. I expect it to be fixed in 9.0.4 version as it seemed to be fixed even for the 9.0.3 version. May it be a regression bug?
Anyway, we are using BigDecimal on entity bean's sequence number and IIRC NUMBER(18) in Oracle tables.
Currently our TopLink version is: 9.0.4 (031126)
Our native sequence has an allocation size of 200 and it matches with SEQUENCEs defined in Oracle.
As we are migratting from TopLink 3.6.3 and we have not changed the sequence prealocation size (we have not touched the database at all) we don't expect the problem to be on sequence prealocation.
I must say we have changed the "default" JDBC driver that TopLink uses when doing the issuing the loging phase (which I think is a SUN driver) to an oracle.jdbc.driver.OracleDriver as we were having problems with timestamp locking.
Any idea?
Thanks in advance.
Ignacio.

Solved!
It was my fault. I was doing a really nasty thing to the entity beans.
I must publicly thank my work mate (which is a pretty smart girl, I must say) in tracking down this issue.
Here is what (we think) was happening:
As I told in previous post in this post we are in the process of moving from TopLink 3.6.3 (EJB 1.1) to TopLink 9.0.4 (EJB 2.0). We do have a "super class" in our application where we had some common things of our entity beans, i.e. entityContext, oid and oca attributes. We have also some methods that retrieve and set values from and to the entity beans via value objects (in order to avoid the heavy RMI operations when doing it through "standard" getters and setters) well, it happened that the current implementation of the "batch setting" method used the getDeclaringMethods to update in both UPDATE and INSERT opperations entity attributes with the data of the value object.
When switching to EJB 2.0 we had to push down both the oid and oca attributes (in order of being able do deploy them) to each final entity bean and now they where being included in the setting process!
You can imagine an scenario like this:
1. ejbCreate() // TopLink issues the SELECT SEQ_XXX NEXT VAL FROM DUAL and sets the oid of the EJB
2. setAttributes() // transfer info from the value object to the newly created EJB: including a setOid(null)!
3. commit() (Before Completion)
4. TopLink detects that the damm object surprisingly DOES NOT have the oid attribute setted so it performs another SELECT SEQ_XXX NEXT VAL FROM DUAL in order to "fix" this big problem.
5. commit() (After Completion) // the object is written to the database with the second value from the sequence whereas the first value is used to identify the entity bean into the identity cache.
Well it may not be "exactly" what is happening but I'm sure we are not so far from reality with our assumptions.
Andrei Ilitchev, thanks for your interest, sorry I could not post this sooner.

Et_ITEM_PRESSED event firing two times

Hi ,
I have a added a button to one of the windows and use the
et_ITEM_PRESSED in the ItemEvent to do something. My problem is whenever I click the button the event fires two times. I thought it was my code but the sample code in the CatchingEvents project does the same.
Does anyone know any wayaround it?
appologise if this question has been asked before (I assumed so but could not find any matches for my search)
Regards,
Indika

Almost all the item event in SBO executes two times before and after SBO events handler works. If you dont catch one of the events SBO will execute two events in one time. To avoide that you should cacth the events before "OR" after the SBO Events Handler Works.
For Example:
Before Action:
If pVal.ItemUID = "1" And pVal.EventType = et_ITEM_PRESSED Then
If Len(oEditText.String) <> 0 Then
If IsNumeric(oEditText.String) Then
If Len(oEditText.String) <> 15 Then
If pVal.Before_Action = True Then
BubbleEvent = False
SBOApplication.SetStatusBarMessage "Federal ID Must be 15 Character", bmt_Short
oTmpForm.Items("41").Click ....
Action Success:If pVal.Action_Success = True Then
Set oItem = oTmpForm.Items("8")
Set oEditText = oItem.Specific
sDocNum = CLng(oEditText.String)
Set oItem = oTmpForm.Items("29")
Set oEditText = oItem.Specific
sJumlah = oEditText.String
If sJumlah = "" Then
BubbleEvent = False
That's all. Hopefully helps.

Hamdi

Apply the same LCR two times on different tables

Hi all
Just one question:
Can I apply the same LCR two times on different tables using only one apply queue?
For example executing two times LCR.EXECUTE(TRUE) in a procedure handler:
LCR.EXECUTE(TRUE);
LCR.EXECUTE(TRUE);
....

Topas,
You need to create new LCR and execute both LCRs.

You can end a SQL command in one of three ways:
* with a semicolon (;)
* with a slash (/) on a line by itself
* with a blank line
A semicolon (;) tells SQL*Plus that you want to run the current command that was entered. SQL*Plus processes the command and also stores the command in the SQL buffer.
A blank line in a SQL statement or script tells SQL*Plus that you have finished entering the command, but do not want to run it yet, but it's stored the command on SQL Buffer.
A slash (/) on a line by itself tells SQL*Plus that you wish to run the command stored on SQL buffer.

Hi i want to execute bapi two times with different paramters....Possible

Hi,
i want to execute bapi twice times.Possible please explain where i put which code.Means i put bind code at doinit() method of conpopnent controller and execute bapi code in doinit() iof view. But for second time where i put bind and execute code.
Regards,
Gurprit
Edited by: GURPRIT BHATIA on Dec 17, 2007 1:24 PM

Hi Gurprit,
For executing the bapi second time, you can put the execute bapi code in the action of the button which is on your form. You need not write the bind code again.

How can I count a method executed numer of times.

Hi,
I want to count that a method executed particular no.of times. If it crosses N no.of times then i should print the count and i should reset the count to zero.
I have tried but i havn't get any idea to do it....Could you please give me some ideas to do it....
-Thanks in Advance

Thanks for reply....my requirement is...suppose i have a code with me...front end sends requests every time...if my code executes the request properly(Eg., a simple transaction) then it goes fine...if my code gets exceptions then i need to send a mail to particular persons...
It is fine till now.....But i should not send mails each and every time.....If my code rises exceptions continously some N no., of times within 5 minutes then i need to send mail.........
I hope you understood my requirement....I have tried for this one.....But I am not getting the solution....

Only firefox executing mysql query two times. but other browser works perfect why?

i am a web developer. and i am facing a problem only with firefox. every time i use MySQL query in my php code fire fox execute it two times. but same query is working fine on other browsers.

Yes, the problem is seen without extensions and also in safe mode.
But, I am starting to think that firefox is running low on memeory or CPU.
Without extensions the possibility of failing is 1 in 3.
I am still unable to explain why closing the browser or aborting the request can cause the stuck request to immediately reach the server.
Is there a way to collect Firefox logs and post it here ?

why should i have to declare 2 times the methods
public void mouseClicked(MouseEvent e) {    }
public void mousePressed(MouseEvent e) {    }
public void mouseReleased(MouseEvent e) {    }
public void mouseEntered(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
to make this program work? why when i declate 1 time this program doesn't work good?
import java.awt.*;*
import javax.swing.;
import java.awt.datatransfer.*;
import java.io.FileReader;
import java.io.IOException;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
public class Main extends JPanel implements MouseListener {
public Main() {
super(new GridLayout(2,2));
final JTextArea jt= new JTextArea("dear test :) ",5,20);
FileReader reader = null;
System.err.println("Error closing reader");
exception.printStackTrace();
JButton bu = new JButton("copiar");
final Clipboard clipboard = getToolkit().getSystemClipboard();
//new add
add(nn);
add(tt);
bu.addMouseListener(new MouseListener() {
public void mouseEntered(MouseEvent e) {
StringSelection data = new StringSelection(jt.getText());
clipboard.setContents(data, data);
public void mouseClicked(MouseEvent e) {
public void mousePressed(MouseEvent e) {
public void mouseReleased(MouseEvent e) {
public void mouseExited(MouseEvent e) {
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("TextDemo");
public static void main(String[] args) {
//Schedule a job for the event dispatch thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
public void mouseClicked(MouseEvent e) {    }
public void mousePressed(MouseEvent e) {    }
public void mouseReleased(MouseEvent e) {    }
public void mouseEntered(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
}

import java.awt.;
import javax.swing.;
import java.awt.datatransfer.*;
import java.io.FileReader;
import java.io.IOException;
import java.awt.event.MouseListener;
import java.awt.event.MouseEvent;
public class Main extends JPanel implements MouseListener {
public Main() {
super(new GridLayout(2,2));
final JTextArea jt= new JTextArea("dear test :) ",5,20);
FileReader reader = null;
System.err.println("Error closing reader");
exception.printStackTrace();
JButton bu = new JButton("copiar");
final Clipboard clipboard = getToolkit().getSystemClipboard();
//new add

add(tt);
bu.addMouseListener(new MouseListener() {
public void mouseEntered(MouseEvent e) {
StringSelection data = new StringSelection(jt.getText());
clipboard.setContents(data, data);
public void mouseClicked(MouseEvent e) { }
public void mousePressed(MouseEvent e) { }
public void mouseReleased(MouseEvent e) {}
public void mouseExited(MouseEvent e) { }
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("TextDemo");
public static void main(String[] args) {
//Schedule a job for the event dispatch thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
public void mouseClicked(MouseEvent e) { }
public void mousePressed(MouseEvent e) { }
public void mouseReleased(MouseEvent e) { }
public void mouseEntered(MouseEvent e) { }
public void mouseExited(MouseEvent e) { }
} the problem is this line bu.addMouseListener(new MouseListener() {
if i change this to bu.addMouseListener(this() {
it gives error saying expected ')'
and then doesn't compile.
i just don't know why , although the program runs when i declare the methods two times,
but i think it's better java code , if i learn it why is this error and correct it

Controller method executed two times
