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.

i created one method called :FileLov
i called this method in PR like:

can any one please help me why this method is invoked two time, how can i resolve this issue.

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.

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.
Cheers,
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.

Robinson

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.

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 JRC executes query two times? (reports.queryengine(?:?) - Executing query: ...)

Hello! Using JRC. While creating the report for viewing, I noticed one interesting thing. Why JRC executes query two times AND first time is executed with default parameters AND if default parameters are NULL the query can be invalid (even if it is marked to convert all database NULLs to defaults in Report Options).
<!break>
1. Why do you need to execute query the first time with these default parameters, which are later set to the others? We need to make some valid default parameters to make everything work. Also it is not efficient to execute unnecessary query.
2. If I'm wrong could you explain please? If I'm right, is it a bug and when do you fix it?
Waiting for answer,

How to use one commandButton to execute two tasks in JSF

I have a form in JSF page which contains different faces components. These faces bind to ADF BC to insert one row in the database when the user press commandButton. Also I need to bind the value of one inputText in that form to managed bean to execute another task in the application when the user press the same commandButton.
The code of the inputText:
<h:inputText value="#{bindings.ProjectNumber.inputValue}"
id="pn"
size="10"
required="#{bindings.ProjectNumber.mandatory}">
The code of commandButton:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}"/>
The managed bean is �findInspector�. I tried to insert inputHidden inside commandButton tag and assign the value of the inputText to the inputHidden as follows:
<h:commandButton actionListener="#{bindings.Commit.execute}"
value="Save"
disabled="#{bindings.Commit.actionEnabled}">
<h:inputHidden value="#{bindings.ProjectNumber.inputValue}" binding="#{findInspector.project}"/>
</h:commandButton>
But it was not work
Please how can I write the code to use the value of the inputText more than one time in the JSF(one to insert one row by using ADF BC and another to use the same value to bind to a managed bean) and how to use one commandButton to execute two tasks in JSF.
Thank you
Waheed

Just dopublic void execute() {
anotherAction(inputValue);
I guess those articles might be interesting about passing params and the usage of inputHidden and also about using datatables:

Yes I did
<managed-bean>
<description>The bean for get project No</description>
<managed-bean-name>projectBean</managed-bean-name>
<managed-bean-class>
mcscm.model.ProjectBean
</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>bindings</property-name>
<value>#{bindings}</value>
</managed-property>
</managed-bean>
Also I changed the method in the managed bean as follows:
public String commandButton_action() {
FacesContext fctx = FacesContext.getCurrentInstance();
ValueBinding vb = fctx.getApplication().createValueBinding("#{bindings}");
DCBindingContainer dcb = (DCBindingContainer) vb.getValue(fctx);
OperationBinding operation = (OperationBinding) dcb.get("projectNumber");
operation.execute();
return null;
where projectNumber is my method in the java class of the application module "TaskInformationImpl". I made this method to be accessed from outside of ADF BC.
I just create a sample code for projectNumber method for testing only as:
public void projectNumber (String data){
System.out.print(data);
In the page Pagedef file I added this :
<methodAction id="projectNumber"
InstanceName="TaskInformationDataControl.dataProvider"
DataControl="TaskInformationDataControl"
MethodName="projectNumber" RequiresUpdateModel="true"
Action="999" IsViewObjectMethod="false">
<NamedData NDName="data" NDValue = "#{bindings.ProjectNumber.inputValue}" NDType="java.lang.String"/>
After I did all of this I get a new error like:
javax.faces.FacesException: #{projectBean.commandButton_action}: javax.faces.el.EvaluationException: java.lang.ClassCastException: oracle.adfinternal.view.faces.model.binding.FacesCtrlAttrsBinding cannot be cast to oracle.adf.model.OperationBinding
Is it very difficult to do this in JDeveloper?. yes ADF BC provide me a lot of facilities, but when I want to do a specific task I face a lot of troubles

How to add one edge in same page two times?

Please help me for this i want to add same edge two time in page, one edge while onload and another also should load but it will show in popup. thanks in advance.

Hi Kobe,
Thanks for listening me.
I agree 11g have some issues unlike 10g. I've tried the same by creating a measure rcount(1) and name it as Page in RPD. I just pulled column Page in pivot table section 'Pivot Table Prompts' it is working but this may not answer your requirements.
I would suggest to use the column in Prompt and go by between operator to allow user to select the rows between.
In the report make Page as prompted.
If you are okay with this can look forward to tweak it further, like values in the prompt multiple of 5 or 10s some thing like that.
let me know updates on the same.

A view is just a stored query, so it has to be executed each time it is referenced in a query.
The two queries should have identical performance. It might be vanishingly faster to parse the first query than the second, but I doubt you would be able to detect the difference.

Action Listener Method called multiple times

I have a page (fragment .jsff), containing a simple input text and a button called "search". When I click on "Search" the action listener is triggered multiple times. (The results are displayed in a table inside a panel collection).
The results are actually coming back ok.
When I debug the code, I can see the action listener method called twice.
Do you know why is that?
What should I be taking care of?
This is my code :
*** Fragment ****
<af:commandButton text="#{identityBundle.search_label}" id="cb1"
actionListener="#{UserDetailsBean.searchUsersListener}"
disabled="#{!bindings.searchUsers.enabled}"/>
*** Managed bean ***
public void searchUsersListener(ActionEvent actionEvent) {
// Add event code here...
DCBindingContainer bindings = (DCBindingContainer)getBindings();
DCIteratorBinding iter = bindings.findIteratorBinding("userIterator");
DCDataRow row = (DCDataRow)iter.getCurrentRow();
User user = (User)row.getDataProvider();
boolean isSearchCriteriaPresent = false;
if(user != null){
String fn = user.getFirstname();
if(fn != null && !fn.trim().equals("")){
isSearchCriteriaPresent = true;
user.setLastname(fn);
user.setNonMTUserLogin(fn);
try {
Map <Object, Object> userMap = PropertyUtils.describe(user);
for(Map.Entry<Object, Object> entry: userMap.entrySet()){
if(entry.getKey() != null && entry.getValue() != null && !entry.getKey().toString().equalsIgnoreCase("class")){
isSearchCriteriaPresent = true;
break;
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
if(!isSearchCriteriaPresent){
user.setFirstname("*");
OperationBinding opBinding = (OperationBinding)bindings.getOperationBinding("searchUsers");
opBinding.getParamsMap().put("user", user);
opBinding.execute();
AdfFacesContext adfFacesCtx = AdfFacesContext.getCurrentInstance();
Map<String, Object> scopePageFlowScopeVar= adfFacesCtx.getPageFlowScope();
scopePageFlowScopeVar.put("userSearchCriteria", user);
ADFContext adfCtx = ADFContext.getCurrent();
Map sessionScope = adfCtx.getSessionScope();
sessionScope.put("userSearchCriteria", user);
setUserSearchCriteria(user);
if(selectedUserID != null){
selectedUserID.setValue(null);
RichTable table = getUserResultsTable();
DCIteratorBinding searchUsersIterator = (DCIteratorBinding)bindings.get("searchUsersIterator");
Row[] rows = searchUsersIterator.getAllRowsInRange();
if(rows.length > 0){
RowKeySetImpl rks = new RowKeySetImpl();
ArrayList keyList = new ArrayList();
keyList.add(rows[0].getKey());
rks.add(keyList);
table.setSelectedRowKeys(rks);
table.setDisplayRowKey(keyList);
refreshState(table);
if(!isSearchCriteriaPresent){
user.setFirstname(null);
else{
deleteUserButton.setDisabled(true);
resetPasswordButton.setDisabled(true);
enableUserButton.setDisabled(true);
disableUserButton.setDisabled(true);
Thanks in advance for your help

Hi,
Can you try this?
1. set partialSubmit=true for the "search" button
2. set "search" button id as partialTrigger in your result table
