What is binding attribute of inputtextfield.

hi,
what is the binding attribute in jsf.
how can we call a valueChange method from this binding method in managed bean.
can we use both value attribute and binding attribute for one textfield.I used both.
the value attribute is pointing the managed bean property which of string type.and binding attribute is pointing to a property of HtmlInputText .I wrote setter and getter for that HtmlInputText field.how to use the getValueChangeListener method on this HtmlInputText.

This article might give new insights: http://balusc.xs4all.nl/srv/dev-jep-djl.html

PanelGrid with binding attribute not rendering when event on page fires

I am having a similar issue with my components not being rendered from a dynamic binding attribute as described by this post:http://forum.java.sun.com/thread.jspa?threadID=671672 but for different reason. I have combed the forum and other sources for a week now, tried numerous variations of this based on suggestions I've read for rendering dynamic components and am unable to find the problem. I would appreciate guidance as I don't know what else to do and I imagine there is something basic about the JSF flow layout or component classes I am not doing correctly.
From a high level, I have a page with two panel groups. The first contains a list of command links (like a menu) that have an actionlistener that populates a list of QueryVariable objects called filterCriteria in the backing bean based on the selection made and then calls a function to update components in the second panel. The second panelGroup contains a panelGrid with a binding attribute that constructs a dynamic set of input fields based on the content of the filterCriteria list. When I first naviagate to this page from another page, the fields are rendered properly. However, if I then select a commandLink from the menu, the panelGrid disappears and is not rendered.
I've stepped through the code in a debugger and my actionlistener is called when I select a command link. However, the binding attribute method is not called at this time, so I added a direct call to it from the action listener. I know the actionlistener is working because I've verified it in the debugger and if I navigate away and come back to the page, then the binding method is called and the new selection is reflected in a rendered panelGrid. Why is it not rendering though when I first select the commandLink and the page is updated. Also, fyi, there is an action method for the commandlinks but it returns null;
FWIW, I'm using MyFaces and Facelets in my application.
Below is my code. This is inside a managed session bean:
JSF Snippet:
<h:panelGrid id="inputVarsTable" columns="3" binding="#{query.table}"/>
     public HtmlPanelGrid getTable() {
          if(table == null)
               table = new HtmlPanelGrid();
          return constructSearchInputTable();

          try {
               for (int i = 0; i < getFilterCriteria().size(); i++) {
                    QueryVariable var = getFilterCriteria().get(i);
                    String id = "var" + i;
                    //<h:outputLabel for="#{var.name}" styleClass="label">
                    outLabel = new HtmlOutputLabel();
                    outLabel.setFor(id);
                    outLabel.setStyleClass("label");
                    // <h:outputText value="#{var.name}" />
                    outText = new HtmlOutputText();
                    outText.setValue(var.getName());
                    outText.setParent(outLabel);

                    String bind = "#{query.filterValues['" + var.getName() + "']}";
                    inText.setValueBinding("value", application.createValueBinding(bind));

          return table;
// Command Link Menu ActionListener
     public void structuredQuerySelection(ActionEvent e) {
          queryType = QueryType.StructuredQuery;
          UICommand cmd = (UICommand) e.getSource();
          filterSelection = (String) cmd.getValue();
          Map<String, SearchRequestCtx> queries = pdp.getGenericMetadata().savedQueries;
          SearchRequestCtx ctx = queries.get(filterSelection);
          filterCriteria = new ArrayList<QueryVariable>();
          filterCriteria.addAll(ctx.getVariables());
          constructSearchInputTable();
     // Command Link Menu Action
     public String selectStructuredQuery()
          return null;
     }BTW, this is my first post and I don't really know how that Duke Dollar thing works but I'm happy to offer some to anyone that can solve this issue for me.
Thanks,

Glad to hear I am not the only one struggling with this type of issue.
I tried your suggestion but it caused a NoSuchElementException when the page tried to render. Stepping through the code, the init function is always called after my panelGrid is constructed. I even commented out the logic to clear the children and confirmed that in the constructed page, the outputText component that binds to init is the first element on the page - right after the opening body tag. Maybe, JSF doesn't necessarily construct the page in top to bottom order? Also, the exception makes me think that this gets called too late in the lifecycle to work. Were you able to get this to work?

Can I change the properties of a Binding attributes in ADF BC?

Hello all,
i have a binding attribute as follow:
<af:inputText id="LnlnmanfBlLoanSmanSmanNam"
value="#{bindings.LnlnmanfBlLoanSmanSmanNam.inputValue}"
label="#{nls['LNLNMANFBLLOAN_SMANSMANNAM']}"
partialTriggers=" LnlnmanfBlLoanSmanSmanCde"
required="false" columns="35" maximumLength="60"
disabled="true"
shortDesc="#{nls['LNLNMANFBLLOAN_SMANSMANNAM_HINT']}">
<f:validator binding="#{bindings.LnlnmanfBlLoanSmanSmanNam.validator}"/>
For example, i want to set disabled to false, how can i access the properties in ADF BC?
Any sample code for reference?
Thanks

Neon,
Is is possible to do that in the VO java layer?Absolutely, no it is not. You cannot access the view layer components from the model like that.
Sounds like what you want to do is this:
<af:inputText id="B"
value="#{bindings.B.inputValue}"
partialTriggers=" A"
required="false" columns="35" maximumLength="60"
disabled="#{empty bindings.A.inputValue}"
<f:validator binding="#{bindings.B.validator}"/>You set the disabled property to a boolean EL expression - the one I used would make the input text disabled if the column A is "empty" (null or empty string)

Using the binding attribute within Tomahawk's t:dataList tag

I am trying to create a .jsp page with a dynamic list of tables. Each table on the page has a dynamic number of columns. I read an excellent blog ([The BalusC Code - Using datatables|http://balusc.blogspot.com/2006/06/using-datatables.html#PopulateDynamicDatatable]) that taught me how to create dynamic tables using the binding attribute. I can now get the tables with dynamic columns working.
What I would like to do next is nest the dynamic tables within a Tomahawk t:dataList tag:
<t:dataList value="#{utilitiesTableSegBean.attributeTables}" var="attributeTable">
    <h:outputText value="#{attributeTable.title}"/>
    <h:panelGroup binding="#{attributeTable.dynamicTableGroup}/>
</t:dataList>
{code}
When I run my app I get this error:
javax.servlet.ServletException: javax.servlet.jsp.JspException: org.apache.jasper.el.JspPropertyNotFoundException: /s/UtilitiesTableSeg.jsp(57,56) '#{attributeTable.dynamicTableGroup}' Target Unreachable, identifier 'attributeTable' resolved to null
Why do I get this error?
If I remove the h:panelGroup tag then the h:outputText tag works just fine. Why does 'attributeTable' resolve to null for the binding attribute of h:panelGroup, yet works for the value attribute of h:outputText?
So then I thought that I might be able to make it work with an index into a bean property that returned the list of table objects. So I tried to modify my panel group tag to:
{code}<h:panelGroup binding="#{utilitiesTableSegBean.attributeTables[0].dynamicTableGroup}"/>{code}
I was just doing a quick initial test and expected to see the first table repeated over and over because I had hard coded the value of '0' as the index. But I was wrong. It listed through all of the tables correctly. Why? This makes no sense to me!
So I changed my jsp again so that it looked like this:
{code}
<t:dataList rowIndexVar="tableIndex" value="#{utilitiesTableSegBean.attributeTables}" var="attributeTable">
    <h:outputText value="#{attributeTable.title}"/>
    <h:panelGroup binding="#{utilitiesTableSegBean.attributeTables[tableIndex].dynamicTableGroup}"/>
</t:dataList>
{code}
This is how I expected to code it so that the tables would all be shown correctly. And it gives this error:
org.apache.jasper.JasperException: An exception occurred processing JSP page /s/UtilitiesTableSeg.jsp at line 57
(Line 57 is the line with the h:panelGroup tag.)
Root cause: javax.servlet.ServletException: javax.servlet.jsp.JspException: java.lang.IllegalArgumentException: null
I would really like to get the original version working, but any feedback and/or suggestions would be greatly appreciated. I have spent a lot of time trying to figure this out and I just don't know where else to look.
Thank you very much!
Dave

Yes, sorry about that - I started off trying to prove a potential solution.
Aim:
A user logs onto a weblogic application and is authenticated against OID. The application is making SOAP service calls to a proxy endpoint monitored by another vendors software which authenticates the user against the ldap and checks their roles to see if the user can call the service.
Solution so far:
The initial application gets the username from the JAAS principal, but the password is not supplied. I can easily supply the SHA password digest to it (but putting a cleartext password in the header will probably not be given the go-ahead). This would enable the application to make the SOAP call with a username and digest.
The software protecting the services can be configured in a variety of ways to authenticate the user to the ldap. One involves using the wsse username token in the header (cleartext password or digest).
This authentication is failing and I don't yet have the diagnostic tools available to see which stage is in error. I was trying to prove that you could actually authenticate with an SHA password digest by doing a bind.

Value and binding attributes?

In a number of UIComponents there is a value and a binding attribute. What is the difference between these attributes and when should one be used vs. the other?

The "binding" attribute is used to bind the tag to a related instance of a component on a backing managed bean.
For example, if you had created an instance of HtmlPanelGrid (called "grid") on a backing bean and had a getter/setter method for that component (getGrid/setGrid), you would use "binding={managedBean.grid}" to tie the <h:panelGrid> tag to the backing instance of component.
The "value" tag is used to assign a value to the component. This may be a String for some components (i.e. outputText) or a List (i.e. dataTable)
The simplest example would be:
<h:outputText value="Hello world!"/>
The preceding tag would render text of "Hello World!"
However... if you were to use binding for that... in your managed bean:
private HtmlOutputText text = new HtmlOutputText();
text.setValue("Hello world!");
public void setText(HtmlOutputText t) {
this.text = t;
public HtmlOutputText getText() {
return text;
Then on the JSP:
<h:outputText binding="#{managedBean.text}"/>
Regards.

Binding attribute

I've successfully implemented a component which reads in the x/y of a mouse down and mouse up click on an image. I now need to get these values to my buisness logic bean.
Based on what I've seen, I have to add a binding attribute to my tag. I'm wondering how, in my tag, how I take this binding attribute and assign it to my component variable on my bean? Does anyone have any sample code on how to do this?
Thanks,
Graham
PS. Can you download the source code for Java Server Faces? It would be easier for me to just view the source of the base components than to keep asking questions on how to do these things.

By "binding" attribute, do you mean, the attribute named "binding"? That's handled automatically by UIComponentTag (as long as you expose "binding" in your TLD).
If you mean "how do I expose support for #{...} syntax on my attribute", then you need code like:
if (title != null) {
if (isValueReference(title)) {
ValueBinding vb = FacesContext.getCurrentInstance().getApplication().createValueBinding(title);
yourComponent.setValueBinding("title", vb);
} else {
yourComponent.getAttributes().put("title", title);
... where "title" is an instance variable of the tag and the name of the component attribute.

Problem with h:dataTable and binding attribute

I am new to JSF and I have a problem using the binding attribute of h:dataTable.
I can successfully use the value attribute to display rows of data fetched from an Oracle database into h:dataTable, but I do know how to bind a h:dataTable to a server object which I would use to update the changes made in the h:dataTable.
Can some body show me an example how to do so ?
Thanks in advance.

I'm not sure whether i understand your problem,
It doesnot need using the binding attribute If you wanna updating the value of each rows in the datatable.
below is a sample that updating each rows of a datatable
jsp file
<h:dataTable value="#[sampleBean.data}" var="row">
    <h:column><h:inputText value="#{row.col1}"/></h:column>
</h:dataTable>
<h:commandButton value="update" action="#{sampleBean.update}"/>BackingBean:
SampleBean.java
public class Samplebean{
private SampleRow[] rows[];
public SampleRow[] getData{
          return rows;
public String update(){
      for(int i=0; i<rows.length; i++){
         rows.update();
return "success";
SampleRow.java
public class SampleRow{
private String col1;
public String getCol1(){
    return col1;
public void setCol1(String col1){
    this.col1 = col1;
public void update(){
     //write your code to save one row data to db/file here

What are the attributes available on Task Status Notification?

Hi,
I need to send the information below when a task is completed or rejected. So I would like to know if they are available. I think so because I've got them from Task Status Notification (OIM standard email definition). If not, what are the attributes available on Task Notification?
<Tasks.Task Name> is <Task Details.Status>.
<Task Details.Status>
<Resource.Resource Name>
Target User: <Users.First Name> <Users.Last Name> [<Users.User ID>]

Hi,
I have implemented some java code to workaround the problem below... But I don't believe this does'n work in OIM :-):-):-):-) Please, tell me if you are using task status notification in OIM and if your email defintion has the variables below.
Thanks,
Hi,
One of OIM email templates is Task Status Email Notification. I am trying to notify the user (Notification tab) using this template but it didn't work. Even when I set the Object Name and Process Name values for an email definition, it does not work.
How have you implemented task status notification in your workflows? I think if this template exists in OIM, by default, so it is posible to have the information below during notifications.
I think I'll have to call Oracle's Support.

I didn't get any answer until now.. Below it is what I've done.
a) Create an entity adapter that is assigned to the post-update of the Specific Task Info data object.
b) Select the task information searching by SCH_KEY, for example (I have to do more tests)
SELECT
sch.sch_key, sch.sch_status, sch.sch_note, mil.mil_key, rsc.rsc_data, rsc.rsc_desc
FROM
osi, sch, mil, rsc
WHERE
mil.mil_key = osi.mil_key and
osi.sch_key = sch.sch_key and
sch.sch_key = ? and
rsc.rsc_key = osi.rsc_key
c) Load the e-mail definition template and replaces the fields
d) Sends the e-mail
With that I solved another problem: I have to send an e-mail always the assignee adds a note to the task.

Jsf 1.2_08 gives me blank page when i use h:panelGrid with binding attribut

I am using jsf 1.2_08 (Mojarra 1.2_08-b06-FCS) + jstl-1.2.jar + Apache Tomcat/6.0.6 + jdk1.5.0_08 on linux suse server. when i load a jsp page with a h:panelGrid, i get a blank page
my panelGrid is as follows
<h:panelGrid id="financialProjections" binding="#{veusSituationMonitorDisplayBean.financialProjections}" border="0" cellpadding="0" cellspacing="0" columnClasses="nspLabel w200,ra bl,ra bl,ra bl,ra bl,ra bld,ra bl,ra bl" columns="8" width="100%"/>

I rather mean that you shouldn't instantiate the HtmlPanelGrid in the bean yourself, but just use the instance which is set through the setter during the restore_view phase.BalusC, why do you recommend this? The spec allows for the bean to create the component:
*JSF 1.2, section 3.1.5* says:
When a component instance is first created (typically by virtue of being referenced by a UIComponentELTag in a JSP page), the JSF implementation will retrieve the ValueExpression for the name binding, and call getValue() on it. If this call returns a non-null UIComponent value (because the JavaBean programmatically instantiated and configured a component already), that instance will be added to the component tree that is being created. If the call returns null, a new component instance will be created, added to the component tree, and setValue() will be called on the ValueBinding (which will cause the property on the JavaBean to be set to the newly created component instance).

Client is reading the Oracle Teleservice Implementation & User Guide Ver 12.1 Page 43-6 Para 7 - "You can use the same extensible attribute architecture to capture additional information for database objects other than service requests"). Client wants to know exactly what is extensible attribute architecture?
Is this the same as setting up descriptive flexfields? If no, what is extensible attribute architecture and how does client set this up?
Here is the comment from client:
Like in Oracle Forms, we have DFFs to add additional attributes to a standard Form, simialarly for OA Framework pages, Oracle provides (via a new architecture) an unlimited number of attributes that can be added to that OA Framework pages. These attributes are called Extensible Attributes. e.g. You can add extensible attributes in the TeleService module to entities like Service Request, Customer and Associated Party. Oracle claims that the same new architecture can be used to extend any database object.
Client wants to use these Extensible Attributes in Oracle Loans module. I posted this to the Loans forum and development suggested I post to Telesales forum as they are not aware of extensible attribute architecture.
Thank you,
Cindy

Hi Cindy,
Extensibility framework and features comes from Oracle Product Lifecycle Management (EGO), it is not a functionality created by Teleservice. Teleservice only uses the extensibility framework. There are other EBS modules that use extensibility framework like, for example, TCA or OCO.
Extensible Attributes are similar to DFF's in the sense that Extensible Attributes feature provides out-of-the box capability to store additional information associated with certain EBS modules entities.
The functionality allows you to view and maintain these additional attributes without having to create custom screens. It also allow you to group related attributes and display attributes on specific UI pages.
Some of the features are:
Limited to certain EBS modules entities.
Attributes can be displayed as text, check box or radio group.
Database view is created for each attribute group.
Uses Value Set for attribute validation.
Extensible Attributes store unlimited number of repeating attributes (multiple rows of similar data), unlike Descriptive Flexfields.
etc.
Components of an extension:
Attribute Group
Attributes
Associations
Pages
Functions
Actions
Value Sets (Recommend creating before attribute groups)
Extensible entities have corresponding tables to store additional attributes.
For example, in the case of Teleservice some of the tables are CS_INCIDENTS_EXT_B, CS_INCIDENTS_EXT_AUDIT, etc.
For TCA you have HZ_PARTY_SITES_EXT_B, HZ_LOCATIONS_EXT_B, etc.
If customer wants to use Extensible Attributes in Oracle Loans then you need to check with Loans Development to see if they implemented or not Extensibility framework.
Thanks,
Walter

What is compounding attributes?how can i create it.?

what is compounding attributes?how can i create it.?

Hi,
when you need additional on\bject to identify each records in master data table....ie a new key in the table...then you go for compounding...so if 24 is the value of A when it is with B then you cmpound B with A.
Just go the compounding option in the infoobject and add this object
thats all !
Thanks

What is navigational attribute?

Hi All,
What is navigational attribute?please tell me in brief.
How can i use it?
give me deep idea about it

HI
Navigational attr are the attributes that can be used as chars in the query (even as they are not a part of the tranasctional data of the InfoProvider). You can see this link for detailed discussion and example:
Re: Navigate Attribute
Key figures can be attributes, but these will only be display attributes. Compounding is a different concept. When you add a compounding char, it means that the value of the basic char does not mean much on its own, and it needs a compounding char to correctly define it. Like Controlling Area is defined as compounded to Cost Element.
Refer thez thread s talks about nav attr with ex
Re: Navigate Attribute
Navigational Attribute
if u r dealing with a Transitive Attribute. Please see this thread which has a discussion on the same:

Prepopulating a property with binding attribute

Hi,
I have a requirement to populate a set of fields when the user changes options in a select box. It works fine if there is no binding attribute defined for that field. If there is a binding attribute, the value set in the bean is not being shown in the page.
For e.g
<h:selectOneMenu id="cardType" value="#{checkoutBean.paymentInfo.cardType}" required="true" binding="#{checkoutBean.paymentInfo.cardTypeComponent}">
</h:selectOneMenu>The value is set is not shown as selected if I have the binding attribute. If I remove binding attribute above it works fine.
Also i tried doing getCardTypeComponent().setValue(cardType) and getCardTypeComponent().setSubmittedValue(cardType), but they are not of any help.
Please let me know how this can be addressed.

Thanks for your help BalusC. I am using MyFaces 1.1. Better post this issue at their own mailinglist. You see, you are here at a Sun JSF forum, not at a Apache MyFaces forum.
Sorry, I won't be able to post piece of code as there are so many dependency between components.Are you insinuating that you haven't even excluded the other components from being suspicious? How did you conclude then that the fault is in the JSF specification?
All I do is
1. Have got a select box. Added a binding attribute to the select box.
2. Trying to populate with a value fethced from DB on certain user action.(For u to test, please set the value from the constructor of the bean..).
whatever value preset is not shown as selected in the select box.Back to point 2: you're presetting it in the constructor of the bean? Do you know that a session scoped bean is created only once per session? Put it in the request scope rather than session scope to get the constructor invoked on every request.
