ManagedBean getter Method called multiple times
Hi,
i have notice that the get method is called so often if i initialize a List.
Maybe you see a solution?
ManagedBean
@ManagedBean(name = "videoBean")
@SessionScoped
public class VideoManagedBean extends GeneralManagedBean {
@PostConstruct
private void init() {
this.newVideos = videoSessionBean.getNewVideos();
public List<VideoEntity> getNewVideos() {
System.out.println("---------getNewVideos--------------");
return newVideos;

Whoa there, jumping to conclusions calling this a problem right from the start.
Yes its expected behavior. The getter can get called from several JSF lifecycle phases. I suggest you study what they are, otherwise you'll run into plenty more of these head scratching moments.

Getter is called multiple times
Hi All,
I my JSF page i am using one foreach which will read elements from an ArrayList. ArrayList is present in one PagesFlowSope-Bean.
I am facing problem that, the getter for ArrayList is called multiple times.I want to restrict that,is there any way for doing this.
Thanks in advance,Your getter gets called every time the component/page gets rendered/refreshed. If you feel that it refreshes too many times, check the partial triggers on that component or its parent. Just a thought, to avoid any logic getting called in your getter multiple times, if possible, put a empty or null check on your attribute and initialize it only if it is null/empty. In that way even if it gets called multiple times your logic to populate your ArrayList doesn't fire everytime.
Good luck ! -
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 helpHi,
Can you try this?
1. set partialSubmit=true for the "search" button
2. set "search" button id as partialTrigger in your result table

Servlet init() method called multiple times
We have a Servlet-based application which does lengthy initialization.
We've noticed that when multiple requests arrive,
but the Servlet's init() method has not returned yet
for the first request, the application server calls init() multiple times.
You can even see this with the Fortune sample
Servlet. Starting the app server and sending 20 or 30
simultaneous requests causes multiple Fortune Servlet init messages to appear in the kjs log.
Why is this? We do not implement SingleThreadModel.
Doesn't the J2EE 1.2 spec say init will be called
only once?
How do we prevent it?
A Startup class which inits our
Servlet?
Or a synchronized block within our init method, with some checks of static member variables
so that the initialization work only happens once?
Or is there some kregedit magic or deployment descriptor change I could make?
Again, it's not a SingleThreadModel issue, so don't
point me there.
This is iAS 6.0 SP4, on Solaris, by the way.Hi
Yes,you are right. In iAS6.0 SP4 When multiple requests arrive,and the Servlet's init() method has not returned yet for the first request, the application server calls init()multiple times. This problem is resolved in iAS 6.5.
There is no kregedit magic that will solve this problem.
Right now the workaround is any of the solution you proposed. Or use iAS6.5. I have tested it with fortune.
Please download it and check with your application.
you can find free download at http://developer.iplanet.com/appserver/testdrive/testdrive_65.html

Listener method is called multiple times
why is a listener method called multiple times when the user interacted
with the component just once?Because you have a bug in your code.
If you want further help post a Short, Self Contained, Compilable and Executable, Example Program ([url http://homepage1.nifty.com/algafield/sscce.html]SSCCE) that demonstrates the problem.
And don't forget to use [url http://forum.java.sun.com/help.jspa?sec=formatting]code formatting when posting code. -
Why a getter method of a managed bean WILL be called multiple times
Why a getter method of a managed bean WILL be called multiple times during the JSF lifecycle?Why this designed?
This is by design indeed. Each step in the JSF lifecycle can call a getter to get the required information.

Backing Bean constructor getting called multiple times
I have a List of records in the Table with a link Add.
When i click Add i show a popup dialog which is attached to the dialogListener.
On clicking OK on the dialog i want to add a record in the List in the backing Bean, but the Bean constructor is getting called multiple times.
and the list to which the table is attached is also getting called multiple times.
is there a way in which the method gets called only once?
Message was edited by:
user607056Hi!
af:table have property ContentDelivery. When <default> (lazy), the table "frame" iz rendered in first page cycle, and content (rows in table) are fetched lazy i.e. in second cycle. Thus, your backing bean is constructed twice.
If you set ContentDelivery to immediate, the table including data rows is generated in single page cycle thus your backing bean is constructed only once.
Hope this helps,

ValidateEntity getting called multiple times
Hi,
There is a parent EO and a child EO. There is a composite association between the parent and child.Association accessors are generated for both source and destination. In the ChildEO's doDML method , the following code is added.
Long abc = getPArentEO().getAttr1();
Long xyz = getPArentEO().getAttr2();
setAttr3(abc);
setAttr4(xyz);
super.doDML();
getParentEO() is the association accessor .
After the addition of this code, all the method validators of the parent are getting fired more than once. The validateEntity of the parentEO is getting called more than once if I set some attribute of the childEO in childEO's doDML . Is this the expected behaviour?
Thanks.Even on adding the setter in prepareForDML (either in parent or child) , the validateEntity is getting called multiple times. In fact ,validateEntity is getting called once before prepareForDML and again after. One of my method validators fail on the subsequent call giving an error ..Please help.

Finalize() method being called multiple times for same object?
I got a dilly of a pickle here.
Looks like according to the Tomcat output log file that the finalize method of class User is being called MANY more times than is being constructed.
Here is the User class:
package com.db.multi;
import java.io.*;
import com.db.ui.*;
import java.util.*;
* @author DBriscoe
public class User implements Serializable {
private String userName = null;
private int score = 0;
private SocketImage img = null;
private boolean gflag = false;
private Calendar timeStamp = Calendar.getInstance();
private static int counter = 0;
/** Creates a new instance of User */
public User() { counter++;
public User(String userName) {
this.userName = userName;
counter++;
public void setGflag(boolean gflag) {
this.gflag = gflag;
public boolean getGflag() {
return gflag;
public void setScore(int score) {
this.score = score;
public int getScore() {
return score;
public void setUserName(String userName) {
this.userName = userName;
public String getUserName() {
return userName;
public void setImage(SocketImage img) {
this.img = img;
public SocketImage getImage() {
return img;
public void setTimeStamp(Calendar c) {
this.timeStamp = c;
public Calendar getTimeStamp() {
return this.timeStamp;
public boolean equals(Object obj) {
try {
if (obj instanceof User) {
User comp = (User)obj;
return comp.getUserName().equals(userName);
} else {
return false;
} catch (NullPointerException npe) {
return false;
public void finalize() {
if (userName != null && !userName.startsWith("OUTOFDATE"))
System.out.println("User " + userName + " destroyed. " + counter);
}As you can see...
Every time a User object is created, a static counter variable is incremented and then when an object is destroyed it appends the current value of that static member to the Tomcat log file (via System.out.println being executed on server side).
Below is the log file from an example run in my webapp.

It really does seem to me like finalize is being called multiple times for the same object.
That number should incremement for every instantiated User, and finalize can only be called once for each User object.
I thought this was impossible?
Any help is appreciated!Thanks...
I am already thinking of ideas to limit the number of threads.
Unfortunately there are two threads of execution in the servlet handler, one handles requests and the other parses the collection of User objects to check for out of date timestamps, and then eliminates them if they are out of date.
The collection parsing thread is currently a javax.swing.Timer thread (Bad design I know...) so I believe that I can routinely check for timestamps in another way and fix that problem.
Just found out too that Tomcat was throwing me a ConcurrentModificationException as well, which may help explain the slew of mysterious behavior from my servlet!
The Timer thread has to go. I got to think of a better way to routinely weed out User objects from the collection.
Or perhaps, maybe I can attempt to make it thread safe???
Eg. make my User collection volatile?
Any opinions on the best approach are well appreciated. -
Php include file getting called multiple times
I have created a form in file career.php. To carry out the validation user_registration.php is called at the beginning of the file.

I am not able to understand why user_registration.php and library.php are executing again and again.
I ran this test on local testing server MAMP.
The results are the same on remote server also.
Please guide.I'm not sure what's happening there. The important question is whether the code is executed successfully.
Since you're using the Zend Framework, it might be better to ask in a dedicated ZF forum. -
Validation Event getting called multiple times
I am saving an eform after entering a wrong percentage in it.On opening the same eform it gives the validate message "Percentage not valid" pop up .This popup should come only once but its coming around 25-26 times.I checked and find that the validate event is getting called multiple times for the same field.Can someone tell why this is happening and how to resolve this

Firefox making same GET call multiple times
Firefox is making the same AJAX call multiple times for a single event when it should really do it once. Actually, with each single click the number of calls multiplies. I have tested the application using Chromium and Eclipse's internal browser and I have no problems.
I removed all add-ons and started Firefox in safe-mode, but the problem persists.
Please advise,
Arthur NobregaHi Arthur, do you have a page available that demonstrates this problem? If so, please post a link. Perhaps your test doesn't actually need to make a network request: for example, perhaps it could add a message to the page indicating that the relevant section of code was triggered.
Since this site focuses on end user support, you might also consider taking this question to a more developer-oriented forum such as the unofficial [http://forums.mozillazine.org/viewforum.php?f=25 mozillaZine Web Development board], or to StackExchange. -
ADF Faces Tree - getChildren() called multiple times
Hi,
I have a simple tree based on the demo's 'tree.jspx'. Each time I click on a node in this tree, I see that TreeNodeImpl.getChildren() gets called multiple times for each node. This is not an issue in tree.jspx where the tree is static. However in a case where tree is constructed dynamically based on the back end state, it is going to hurt performance. Each getChildren() call then invokes backend methods which could be remote. So multiple getChildren() will invoke backend methods multiple times.
Is this behavior of calling getChildren() multiple times per node a bug? Is there any way for me to avoid it?this is expected behaviour.
Your tree model should cache data and prevent the multiple calls to the back end.
