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.

Custom tag library called multiple times

Hi ppl ,
I have a custom tag library which i use to populate some menu components. When i do call my custom tag library though , it is called multiple times, use case is as follows.
I have menu tabs and menu bars which thanks to Mr.Brenden is working splendidly as so:-
<af:menuTabs>
<af:forEach var="menuTab" items="#{bindings.menu.vwUserMenuTabRenderer.rangeSet}">
<af:commandMenuItem text="#{menuTab.MenuLabel}"
shortDesc="#{menuTab.MenuHint}"
rendered="true"
immediate="true"
selected="#{sessionScope.selectedMenuId == menuTab.MenuId }"
onclick="fnSetSelectedValue('#{menuTab.MenuId}')" >
</af:commandMenuItem>
</af:forEach>
</af:menuTabs>
<af:menuBar>
<af:forEach var="menuBar" items="#{bindings.menu.vwUserMenuBarRenderer.rangeSet}">
<af:commandMenuItem onclick="return clickreturnvalue()"
onmouseover="dropdownmenu(this, event,#{menuBar.MenuId}, '150px')"
onmouseout="delayhidemenu()"
text="#{menuBar.MenuLabel}"
action="#{menuBar.MenuUri}"
rendered="#{menuBar.ParentId == sessionScope.selectedMenuId}"
immediate="true" />
</af:forEach>
</af:menuBar>
</afc:cache>
now all of this code is within a subview , and just directly below the subview tag , i have the call to my custom tag library:-
<myCustomTagLib:menuCascade />
only issue now is that assuming i have in all 7 menu bar components, the doStartTag is called 7 times. the relevant code within my custom tag class is as follows :-
public int doStartTag() throws JspException {
return (EVAL_BODY_INCLUDE);
public int doEndTag() throws JspException {
try {
declareVariables();
return EVAL_PAGE;
}catch (Exception ioe) {
throw new JspException(ioe.getMessage());
and within my declareVariables method i do an out of the jscript ( out.print(jscript.toString()); ) which is a simple string generated based on certain conditions...
now it seems to be working fine on the front end , but when i view the source of the page, i notice that the declaration is called multiple times, and this happens because the doStartTag method is called multiple times, i haven't even nested the call to the custom tag within the menu components , any clue as to whats going wrong ?
Cheers

Hi,
if you add the following print statement
System.out.println("rendering "+FacesContext.getCurrentInstance().getViewRoot().getViewId());
Then the output in my case is
07/04/24 08:14:04 rendering /BrowsePage.jsp
07/04/24 08:14:05 rendering /otn_logo_small.gif
The image comes from the file system, which means it is rendered by the JSF lifecycle. If you reference the image with a URL then the lifecycle doesn't render the image but only refrences it.
To avoid your prepare render code to be executed multiple times, just check for jsp and jspx file extensions, which will guarantee that your code only executes for JSF pages, not for loaded files.
The reason why this happens is because the JSF filter is set to /faces , which means all files that are loaded through that path

CommandLink Disabled called multiple times

Hello,
I'm developing a brief method to enable/disable af:commandLink on certain condition.
The layout is simple: a table to the left and a panelTabbed to the right. PanelTabbed has a partialTrigger to the table.
In a visible tab there is a commandLink with Disabled attribute bound to a backingBean method.
In this method I placed a System.out.println and I can see that this method is called multiple times.
On pagestart the method is called 2 times.
On table current row change the method is called 3 times.
On tab change out of first tab 1 time.
On tab change to first tab 2 times.
I wen through all the way from commandLink to top component and there are no additional partialTriggers.
Could someone explain this to me, please?
Thanks.
ADF 11.1.1.4

Ilya,
Have you tried using the ADF logger (see [url http://blogs.oracle.com/groundside/entry/adventures_in_logging_index]this blog for lots of details, especially part 5)? Replace your System.out.println calls with calls to the logger, crank up the logging level and use the log analyser to see by ADF/JSF phase when things are called.

On Execute operation, the bean getter is being called multiple times

Hi,
I have a JCR data control, i am trying to write a method that returns predicate, but this method is being called multiple times, when executing the advanced search operation.
public List<Predicate> getPredicates() {
ArrayList<Predicate> predicates = new ArrayList<Predicate>();
   // predicates.add(new Predicate("jcr:content/idc:metadata/idc:xScope",Operator.EQUALS,"GLOBAL"));
DCBindingContainer bc=(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
JUCtrlListBinding attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("StateId");
Object stateId= attrBinding.getSelectedValue();
if(stateId instanceof Row){
predicates.add(new Predicate("jcr:content/idc:metadata/idc:xState"
, Operator.EQUALS
,((Row)stateId).getAttribute("StateId").toString()));
attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("DistrictId");
Object districtId=attrBinding.getSelectedValue();
if(districtId instanceof Row){
      predicates.add(new Predicate("jcr:content/idc:metadata/idc:xDistrict",Operator.EQUALS,((Row)districtId).getAttribute("DistrictId").toString()));
    attrBinding=(JUCtrlListBinding) bc.findCtrlBinding("Scope");
    Object scopeId=attrBinding.getSelectedValue();
    if(scopeId instanceof Row){
        predicates.add(new Predicate("jcr:content/idc:metadata/idc:xScope",Operator.EQUALS,((Row)scopeId).getAttribute("ScopeType")));
    AttributeBinding tempAttrBinding=(AttributeBinding)bc.findCtrlBinding("CreatedDate");
    Object createdDate=tempAttrBinding.getInputValue();
    if(createdDate!=null){
        predicates.add(new Predicate("jcr:content/jcr:created",Operator.EQUALS,createdDate.toString()));
    if (predicates.size()>0){
      return predicates;
return Collections.emptyList();
} The problem is while it's being called multiple times different list's are being returned which is causing the method not to work . The bean is in pageFlowScope .

That is bc ADF life cicle... Is always executing 2 times...

Unable to implement Programmatic ADF Faces Tree component in jdev 11g

I have referred to the posts " [Back to programming: Programmatic ADF Faces Tree component|http://one-size-doesnt-fit-all.blogspot.com/2007/05/back-to-programming-programmatic-adf.html] " and " [Follow-up: Programmatic ADF Faces Tree in JDev 11g|http://one-size-doesnt-fit-all.blogspot.com/2007/05/follow-up-programmatic-adf-faces-tree.html] ",
The first post showed how to construct the elements in the tree programmatically rather than relying on bindings (in JDeveloper 10.1.3)
and the second post tells the only difference in 11g .
I am trying to implement the elements of the tree programatically in Jdev 11g(specifically 11.1.1.0.2) but no result is coming .
There is no compilation/run time error , its just that the tree is not visible.
Can anyone suggest any key points which should be focussed during this implementation?

Hi,
follow the description
http://www.oracle.com/technology/products/adf/adffaces/11/doc/demo/adf_faces_rc_demo.html
to install the ADF Faces RC component demo in JDeveloper. It has a tree example. Have a look at their implementation and dapt it to your needs

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.

Generic Data Source is calling multiple times in RSA3

Hi experts,
I have the requirement to get data from Generic Data Sources with function Module,

in the internal table I_T_DATA is displays 281 records,
but in RSA3 it shows 112560 records, I found that the FM is calling multiple time by executing one time in RSA3.
1.what would be the problem

Hi Savita,
I don't understand clearly from your reply regarding flow you transported and what all you transported.
You need to first transport objects in R/3 and import them.
Then transport Infoprovider, Datasource in BI assuming depenedent Infoare Infoobject, application component already transported.
Then transport your Infosource, Update rule, Transfer rules, Infopackage.
Hope you understood.

ADF Faces: dialog framework calls twice prepareModel and prepareRender

Hi ,
does anybody know why ADF Faces dialog framework calls twice prepareModel and prepareRender lifecycle methods . That's a really problem for me because i'm calling db procedures through backing beans methods which are attached on components properties.
I cannot allow myself to cal the procedures more than once.
Can somebody help me?
Krasi

Okay, although the servlet doesn't require to be run inside the JSF context, I added "/faces" to the URL simply because this would allow me to query the "postback" flag. In other words, I changed the invocation URL from "/jrrun" to "/faces/jrrun".
In the servlet's "service()" method I put:
logger.debug(">>>>>> isPostBack? " + AdfFacesContext.getCurrentInstance().isPostback());
I also attached a JSF PhaseListener to the whole thing.
Then I opened the parent page, I clicked on the button and the dialog appeared. The console output follows:
07/01/19 21:37:05 ------------- start of phase RESTORE_VIEW 1
07/01/19 21:37:05 ------------- end of phase RESTORE_VIEW 1

By the way, partialSubmit="true" has the same effect as partialSubmit="false".
I'm not sure I understand you correctly. Or perhaps you don't understand me correctly.
I haven't got a problem with the parent page. I have a problem with the dialog page. It's executed twice. The RENDER_RESPONSE phase (as well as the RESTORE_VIEW phase) is executed twice.
I want it to be executed only once. I don't want the servlet to be executed twice.
Let me point out again that in the Embedded OC4J (inside JDeveloper) everything is okay. The servlet is executed only once. However, the same thing on OAS 10.1.3.1 runs twice.

Php include file getting called multiple times

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.

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?

Hi!
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,

Oracle Object Type Constructor Called Multiple Times

I have an object type with a custom constructor. In SQL, when I reference the attributes the constructor is called multiple times in Oracle 11.2.0.4.
Why is the constructor called multiple times?
How do I stop it?
My current work around is to reference the attributes and use the /*+ materialize */ hint.
Problem Setup
    create or replace type Foo as object
      Bar1 NUMBER,
      Bar2 NUMBER,
      Bar3 NUMBER,
      CONSTRUCTOR FUNCTION Foo(p_Bar1 NUMBER, p_Bar2 NUMBER, p_Bar3 NUMBER)
        RETURN SELF AS RESULT
        DETERMINISTIC
    create or replace type body Foo is
      -- Member procedures and functions
      CONSTRUCTOR FUNCTION Foo(p_Bar1 NUMBER, p_Bar2 NUMBER, p_Bar3 NUMBER)
        RETURN SELF AS RESULT
        DETERMINISTIC
      AS
      BEGIN
        SELF.Bar1 := p_Bar1;
        SELF.Bar2 := p_Bar2;
        SELF.Bar3 := p_Bar3;
        dbms_output.put_line('Foo Constructor Called');
        RETURN;
      END;
    end;
Problem
    -- Constructor is called 6 times!
    -- Once for each column and once for each predicate in the where clause.
    SELECT x.f.bar1 AS bar1, x.f.bar2 AS bar2, x.f.bar3 AS bar3, f
    FROM (
      SELECT foo(p_Bar1 => 1, p_Bar2 => 2, p_Bar3 => 3) f
      FROM dual d
    ) x
    WHERE x.f.bar1 = x.f.bar1 AND x.f.bar2 = x.f.bar2
Output
Foo Constructor Called
Foo Constructor Called
Foo Constructor Called
Foo Constructor Called
Foo Constructor Called
Foo Constructor Called
Workaround
    -- Work Around
    -- Constructor is called 3 times
    -- Once for each column in the inline view.
    -- Note, I removed column f (the object type) because it's not compatible with the materialize hint.
    WITH y AS (
      SELECT /*+ materialize */ x.f.bar1 AS bar1, x.f.bar2 AS bar2, x.f.bar3 AS bar3
      FROM (
        SELECT foo(p_Bar1 => 1, p_Bar2 => 2, p_Bar3 => 3) f
        FROM dual d
      ) x
    SELECT y.bar1, y.bar2, y.bar3
    FROM y
    WHERE y.bar1 = y.bar1 AND y.bar2 = y.bar2

Another work-around is described in this thread... Accessing fields of a custom object type... which makes use of a collection type combined with the TABLE operator, like so...
create or replace type FooTable as table of Foo;
SELECT x.bar1 AS bar1, x.bar2 AS bar2, x.bar3 AS bar3, value(x) f
    FROM table(FooTable(
      foo(p_Bar1 => 1, p_Bar2 => 2, p_Bar3 => 3)
    )) x
    WHERE x.bar1 = x.bar1 AND x.bar2 = x.bar2
BAR1 BAR2 BAR2 F
1    2    3    (1, 2, 3)

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

JDK 6: requestPasswordAuthentication called multiple times

Hi...
Has anyone else noticed that 'requestPasswordAuthentication' gets called multiple times from HTTPURLConnection in JDK 6? If I create an HTTPURLConnection, and it returns successfully from 'openConnection', if I then do something simple like query for its contentType via 'getContentType', a call to my authenticator requesting password authentication is made MULTIPLE times...
In JDK 1.5, it was only made once in the same scenario.
Have there been changes in the recent release that would require me to make changes to my authenticator or to supply more information?
Thanks!
Kelly

We had a problem with NTLM authentication in 1.5 and Java SE 6, which may be the problem that you are seeing. There were actually two bugs in the same area that were fixed, 6520665 and 6357133.
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6520665
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6357133
Both these bugs were fixed in the following releases:
jdk 7 b12
jdk 6 u3 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=2148156
jdk 5u13 http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=2149272
I know that none of these releases are available yet except for jdk7. There is an early access version available from http://download.java.net/jdk7/binaries/ . Maybe you could install it an see if it resolves your problem.

IPhone - Sybase RFC called multiple times

Hi,
I have an RFC that is adding some data in the system. This works, how ever it gets called multiple times with the same data. Every time a synchronization is done it adds a new row with all the same data. (even with 1 entry so it's not because of the loop).
This is how my save function looks, newEntriesMBO is an array with Synchronization parameters. Should I do anything more than [sync delete]?
        for (TimeSheets_EnterTimeDataSynchronizationParameters *sync in newEntriesMBO)
            [sync save];
            while ([TimeSheets_TimeSheetsDB hasPendingOperations])
                [NSThread sleepForTimeInterval:0.2];
            [sync delete];

Hi
Once the personalization parameters are set ,you should call [pp save];
the next step would be to check for pending operations
while (TimeSheets_TimeSheetsDB hasPendingOperations)
NSThread sleepForTimeInterval:0.2;
Thats it no more code. sync delete etc is all not required. The reason why u get multiple calls is because pp save function is called multiple times.
Thanks

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.
