Bean datacontrols and managed beans

Hi,
When I use bean data controls, my bean from which the datacontrol is created is in session scope. In this case, should I be using another managed bean for the UI purpose or shall I use the "data control bean" ?
For eg:
I have a an EmployeeManager which returns a list of employees. Now I created a data control from my EmployeeManager. And I create a table of employees on my jspx. Suppose I want to keep the last selected employee record for some back end processing ( maybe a web service call to get the Employee Salary details) , shall I keep the selected Employee in my EmployeeManager or should I have a managed bean?
If I keep this in managed bean, again I need it in my EmployeeManager for back end call. Please guide me.
Thanks,
Manoj

Model layer binds presentation layer to business logic and data services and vise versa. In ADF applications the model layer is implemented as ADF DataControls + ADF Bindings. The presentation layer is implemented usually as UI. The business logic and data services may be implemented in various ways (ADF BC, EJB, POJO, Java Beans, Web Services, etc.). See this ADF architecture diagram.
You should separate these layers from each other. In this way you will be able to replace the implementation of some layer without re-engineering the other ones (for example, to replace the bean-based data services with ADF based ones without re-engineering the user interface).
Keeping track of the current records is responsibility of the model layer and the business/data services. The JSF managed beans are not a proper place to do it because they are part of the presentation layer. (In theory if you have good application architecture and you replace the implementation of the data service, then you should not be forced to modify the presentation layer too).
ADF iterator bindings (defined in PageDefs) have a built-in funtionality for keeping track of current rows. In my opinion, they have this functionality regardless of the kind of the data services they are based on, so if you use ADF bindings you should have this functionality out-of-the-box even in case of a bean-based DataControl.

How do I use a managed bean in another managed bean

I have two managed beans. One is backing bean for a form and the other is used to access a database table.
1st bean
public class TestDBAO
@PersistenceContext
private EntityManager em;
public void addEntry(PersonObj person)
em.persist(person);
public class formdata
private String id;
private String fname;
private String lname;
getter functions
setter functions
public String submit()
in here i want to call addEntry function from TestDBAO
How can I achieve this or is there another way to do this?

Do I understand correctly that you have definied TestDBAO as a session scoped managed bean? Why?
You don't need that. Just create and call TestDBAO in the backing bean. Or if you want only one instance of TestDBAO during the session, then create a singleton constructor and eventually make the methods static.

Error calling Method on Managed Bean from another Managed Bean

Hi
(Jdev 11.1.1.2.0)
Help please:
I have a managed bean (page flow scope) which is used by my main page for dynamic region flow navigation:
*public class RegionNavigationBean implements Serializable{*+
private String dynamicTaskFlowId = "/WEB-INF/home-task-flow-definition.xml#home-task-flow-definition";+
*public RegionNavigationBean() {*+
*public TaskFlowId getDynamicTaskFlowId() {*+
return TaskFlowId.parse(dynamicTaskFlowId);+
*public void setDynamicTaskFlowId(String taskFlowId) {*+
this.dynamicTaskFlowId = taskFlowId;+
taskFlowId property on main page def is set to +*${pageFlowScope.regionNavigationBean.dynamicTaskFlowId}*+
In a DB table (i.e. View Object on my model layer) I store a menu ID and a corresponding task_flow_id.
Then I have created an action listener class (RegionNavigationListener - page flow scope) which I link to my menu items on my main page (action listener property on menu item = +*#{pageFlowScope.regionNavigationAction.processAction}*+ )
In this action listener (processAction method), I retrieve the row set from the menu VO and find the record which matches my menu ID which caused the action event, thereby retrieving the task_flow_id which must be navigated to.
I then try to retrieve the instance of the RegionNavigationBean with the following statement: RegionNavigationBean regNav = (RegionNavigationBean)JSFUtils.getManagedBeanValue("regionNavigationBean");+
This seems to work fine, but as soon as I try and use this I get NullPointerException error, e.g.:
regNav.setDynamicTaskFlowId(menusRow.gettaskFlowId());+
or even:
System.out.println("%%% " + regNav.toString());+
This is all quite new to me... any help would be appreciated!
Thanks
Mario

Hi Mario,
I think JSFUtils.getManagedBeanValue(String) has difficult to evaluate the "regionNavigationBean" managed bean.
What JSFUtils.getManagedBeanValue(String) do is important. I remember that "JSF scoped" bean can be found by JSF style find method, such as requestScope, sessionScope, applicationScope. For a managed bean put in these scope, scope prefix is not needed, for example: using #{beanName} to locate a requestScope bean. The #{requestScope} prefix is not needed.
But pageFlowScope is different. If a bean is put in the pageFlowScope, you must use #{pageFlowScope.beanName} to locate it.
Say, ManagedBean is the java class of your manged bean.
FacesContext ctx = FacesContext.getCurrentInstance();
Application app = ctx.getApplication();
ManagedBean mb = (ManagedBean)app.evaluateExpressionGet(ctx, "#{pageFlowScope.managedBeanName}", ManagedBean.class);
Hope it helps.

Share stateful session bean in JSF managed beans with different scope

Hi,
I have a JSF application and I want to try to use of stateful session beans.
So I created a new stateful session bean and its local interface.
@Stateful
public class StatefulSessionBean implements StatefulSessionBeanLocalInterface{
private String name;
@Local
public interface StatefulSessionBeanLocalInterface {
...In my JSF application I have a mananed bean with session context which registers the new interface by
this annotation
@EJB(name="sessionbeanref", beanInterface=StatefulSessionBeanLocalInterface.class) and set the name to something.
Now I want to fetch this name in another managed bean with request scope. So I looked up the bean and tried to get the name.
StatefulSessionBeanLocalInterface = (StatefulSessionBeanLocalInterface) new InitialContext().lookup("java:comp/env/sessionbeanref");
System.out.println(currentmailingbean.getName());but the name is null.
Why?

The xsd was created via the netbeans J2EE enterprise application dialog and I think its the most recent.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">All other annotations seem to work.
Wouldnt the lookup completely fail if the deployment process thought that it is version 1.4 ?

ADF Faces and BC: Scope problem with managed bean

Hi,
I am using JDev 10.1.3 and ADF Faces with ADF BC.
I have created a managed bean which needs to interact with the binding layer and also receive actions from the web pages. I have a managed property on the bean which is defined as follows:
<managed-bean>
    <managed-bean-name>navigator</managed-bean-name>
    <managed-bean-class>ecu.ethics.view.managed.Navigator</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
      <property-name>bindings</property-name>
      <value>#{bindings}</value>
    </managed-property>
</managed-bean>I need the been to session scope because it needs to keep previous and next pages to navigate the user through their proposal. If i use session scope (as above) i get the following error when i click on a comand link which references a method in the above bean: #{navigator.forwardNext_action} which returns a global forward.
this is the exception:
javax.faces.FacesException: #{navigator.forwardNext_action}:
javax.faces.el.EvaluationException: javax.faces.FacesException:

Hi pp,
you need to create a managed (not backing) been set to session scope.
You can call/reference the managed bean from your page.
the backing bean is designed around a page lifecyle which is request oriented in it's design.
This is a simple managed bean from faces-config.xml
<managed-bean>
    <managed-bean-name>UserInfo</managed-bean-name>
    <managed-bean-class>ecu.ethics.admin.view.managed.UserInfo</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
      <managed-property>
      <property-name>bindings</property-name>
      <property-class>oracle.adf.model.BindingContext</property-class>
      <value>#{data}</value>
    </managed-property>
</managed-bean>and the getters and setters for bindings in your session scope managed bean:
    public void setBindings(BindingContext bindings) {
        this._bindings = bindings;
    public BindingContext getBindings() {
        return _bindings;
    }you can access the model from the managed bean using the the BindingContext if needed.
also have a look at JSFUtils from the ADF BC SRDemo application, there are methods in this class such as resolveExpression which demonstrate how to get the values of items on your page programatically using expression language. You can use this in your managed bean to get values from your pages.

Brenden

Accessing facade bean in ADF Faces managed bean

Hello
I am trying to display data from a database on a page using ADF Faces. I am using a Web Application [JSF, EJB] template in JDeveloper with the model project using JPA entities with a session facade bean to manage the entities (as described here: http://www.oracle.com/technology/obe/obe1013jdev/10131/ejb_and_jpa/master-detail_pagewith_ejb.htm ).
What I have tried to do is to set up a managed session bean in the ViewController project that is referenced by a faces page. The managed bean is supposed to, on creation, load data from the database into managed properties which are then displayed on the faces page using EL references. I want all JPA management to go through the facade, and thus I want to inject the facade bean into the managed bean using @EJB notation. However, the injection does not work, and all I get is a NullPointerException when trying to access the injected facade in the managed bean.
I have also tried instantiating the facade bean in the managed bean's constructor manually, but when I try to call a method on the facade, I get another NullPointerException, this time from the entity manager which obviously is not injected into the facade bean.
What is strange is that the facade bean works perfectly when I use the datacontrols generated from the facade bean, as described in the tutorial (no exception from the entity manager).
I have searched high and low for a solution to this, and from what I can read, it should be possible to do what I want (see for example https://blueprints.dev.java.net/bpcatalog/ee5/persistence/ejbfacade.html and http://luxlog.wordpress.com/2007/12/15/basic-example-web-app-with-glassfish-netbeans-60-jsf-and-ejb3/ ). I found someone mentioning that dependency injection in the web container OC4J was added after a given version, and that web.xml needs to be upgraded to version 2.5, which I have done but did not solve anything.
Is this not possible in JDeveloper/OC4J at all? Is there any other way to access the facade session bean in managed beans?

Hi,
for resource injection you need JDeveloper 11. Here the EJB annotation works to inject the resource. If you want to do similar in 10.1.3 then you need to do a JNI lookup in the managed bean (under the shelves ADF does the same)

Session scope managed bean is not instantiating?

We have the need to use a session bean (rather than pageFlowScope) in our application. But it looks like the session beans are not being instantiated at run time like other beans are. I created a simple test case to verify. One bean, named "MySessionBean", defined in the task flow as Session scope, then referenced in a view with an input text box, value: #{sessionScope.MySessionBean.value1}. When I run the application, I just get PropertyNotFoundException, Target Unreachable, 'MySessionBean' returned null.
If I simply change the bean to use pageFlowScope, everything works fine.   I have debug code in the bean constructor, and it never gets called.   Is there some other step I am missing to have ADF instantiate the session bean?

No luck, I tried it in both adfc-config.xml, and faces-config.xml. I also tried moving the call to my view, from my bounded taskflow, into the adfc-config unbounded task flow, and then I ran that instead. Still got the same error.    Here is my code from the the last round of tests with the view called in the main adfc-config.xml unbounded taskflow:

Generate PDF using Managed Bean with custom HTTP headers

Background
Generate a report in various formats (e.g., PDF, delimited, Excel, HTML, etc.) using JDeveloper 11g Release 2 (11.1.2.3.0) upon clicking an af:commandButton. See also the StackOverflow version of this question:
http://stackoverflow.com/q/13654625/59087
Problem
HTTP headers are being sent twice: once by the framework and once by a bean.
Source Code
The source code includes:
- Button Action
- Managed Bean
- Task Flow
Button Action
The button action:
<af:commandButton text="Report" id="submitReport" action="Execute" />
Managed Bean
The Managed Bean is fairly complex. The code to `responseComplete` is getting called, however it does not seem to be called sufficiently early to prevent the application framework from writing the HTTP headers.
HTTP Response Header Override
* Sets the HTTP headers required to indicate to the browser that the
* report is to be downloaded (rather than displayed in the current
* window).
protected void setDownloadHeaders() {
HttpServletResponse response = getServletResponse();
response.setHeader( "Content-Description", getContentDescription() );
response.setHeader( "Content-Disposition", "attachment, filename="
+ getFilename() );
response.setHeader( "Content-Type", getContentType() );
response.setHeader( "Content-Transfer-Encoding",
getContentTransferEncoding() );
Issue Response Complete
The bean indirectly tells the framework that the response is handled (by the bean):
getFacesContext().responseComplete();
Bean Run and Configure
public void run() {
try {
Report report = getReport();
configure(report.getParameters());
report.run();
} catch (Exception e) {
e.printStackTrace();
private void configure(Parameters p) {
p.put(ReportImpl.SYSTEM_REPORT_PROTOCOL, "http");
p.put(ReportImpl.SYSTEM_REPORT_HOST, "localhost");
p.put(ReportImpl.SYSTEM_REPORT_PORT, "7002");
p.put(ReportImpl.SYSTEM_REPORT_PATH, "/reports/rwservlet");
p.put(Parameters.PARAM_REPORT_FORMAT, "pdf");
p.put("report_cmdkey", getReportName());
p.put("report_ORACLE_1", getReportDestinationType());
p.put("report_ORACLE_2", getReportDestinationFormat());
Task Flow
The Task Flow calls Execute, which refers to the bean's `run()` method:
entry -> main -> Execute -> ReportBeanRun
Where:
<method-call id="ReportBeanRun">
<description>Executes a report</description>
<display-name>Execute Report</display-name>
<method>#{reportBean.run}</method>
<outcome>
<fixed-outcome>success</fixed-outcome>
</outcome>
</method-call>
The bean is assigned to the `request` scope, with a few managed properties:
<control-flow-rule id="__3">
<from-activity-id>main</from-activity-id>
<control-flow-case id="ExecuteReport">
<from-outcome>Execute</from-outcome>
<to-activity-id>ReportBeanRun</to-activity-id>
</control-flow-case>
</control-flow-rule>
<managed-bean id="ReportBean">
<description>Executes a report</description>
<display-name>ReportBean</display-name>
<managed-bean-scope>request</managed-bean-scope>
</managed-bean>
The `<fixed-outcome>success</fixed-outcome>` strikes me as incorrect -- I don't want the method call to return to another task.
Restrictions
The report server receives requests from the web server exclusively. The report server URL cannot be used by browsers to download directly, for security reasons.
Error Messages
The error message that is generated:
Duplicate headers received from server
Error 349 (net::ERR_RESPONSE_HEADERS_MULTIPLE_CONTENT_DISPOSITION): Multiple distinct Content-Disposition headers received. This is disallowed to protect against HTTP response splitting attacks.Nevertheless, the report is being generated. Preventing the framework from writing the HTTP headers would resolve this issue.
Question
How can you set the HTTP headers in ADF while using a Task Flow to generate a PDF by calling a managed bean?
Ideas
Some additional ideas:
- Override the Page Lifecycle Phase Listener (`ADFPhaseListener` + `PageLifecycle`)
- Develop a custom Servlet on the web server

Thank you!

The problem was that the HTTP headers were in fact being written twice:
1. The report server was returning HTTP response headers.
2. The bean was including its own HTTP response headers (as shown in the question).
3. The bean was copying the entire contents of the report server response, including the headers, into the output stream.
Firefox ignored the duplicate header errors, but Google Chrome did not.

Action / actionListener in h:commandButton with managed beans

I have a problem with a backing bean whose method is not invoked when i click it. I've seen some posts on here about this yet, I still don't understand what I am doing wrong, if anything.
Some context...I've modeled my application after 'jcatalog' from this article:
http://www.javaworld.com/javaworld/jw-07-2004/jw-0719-jsf.html . It's simpler than the article -- I'm not using Spring/Hibernate and the persistence is the file system. For each business object (Resource), there's a backing bean (ResourceBean).
In short, I can't get the backing bean to respond to the button event for 'Add' bound to addAction. This is just like the jcatalog 'createProduct' impl -- which doesn't use the (FacesEvent fe ) approach.
Anyway, I would appreciate anyone's help to get past this.

(Note, the applicationBean uses view services manager. The manager is used by the ResourceBean. (It's initialized by the h:output dummy variable reference at the top of my .jsp page)). I can see the initialization in the debug trace.

Hey, anyway, have you note your jsp reference to the backing bean begins with a lowercase letter, and your backing bean class name begins with an uppercase letter?? I think that's it... I think, cause I'm too unexperienced in JSF.... Bye!!

Managed bean returns null on SetActionListener

Hi,
I'm trying to implement a filter for my table (something similar to what's done in the "OracleAS 10g R3: Oracle ADF for Forms/4GL Developers/Volume II" student guide, practice 9-5). The idea is to have a request-scoped managed bean which holds the filter value - the value is set using a SetActionListener, and later bound to a bind variable in a view with a view criteria. I have problem re-creating this in Trinidad (JDev 11 TP3, to be exact).
I have created a request-scoped bean in adfc-config.xml (called 'ecnStatusBean'), with a managed property (named 'Status'). I am referencing it from my SetActionListener: setting #{'E'} to #{requestScope.ecnStatusBean.Status}. The reference compiles fine in the Expression Builder (it didn't before I created the managed bean), but when running and clicking the CommandLink with the SetActionListener, I get a runtime error:
oracle.security.jazn.JAZNRuntimeException: Target Unreachable, 'ecnStatusBean' returned null
     at oracle.security.jazn.oc4j.JAZNFilter.doFilter(JAZNFilter.java:480)
To make things more interesting, I tried changing the scope to session, and got a different error:
oracle.adf.controller.ControllerException: ADFC-10001: Cannot instantiate class 'pelephone.cdma_ecn.ecn_manager.model.ecnStatusMB'.
     at oracle.adfinternal.controller.util.Utils.createAndLogFacesException(Utils.java:169)
Am I doing a rookie's mistake? Is this a Trinidad issue? Something else?
Thanks in advance for any help,
Boris

Are you sure about the reference you use here: #{requestScope.ecnStatusBean.Status}.
Here is a simple sample of what works for me:
The first page has this:
      <af:form binding="#{backing_start.form1}" id="form1">
        <af:inputText label="Label 1" binding="#{backing_start.inputText1}"
                      id="inputText1"/>
        <af:commandButton text="commandButton 1"
                          binding="#{backing_start.commandButton1}"
                          id="commandButton1" action="go">
          <af:setActionListener from="#{backing_start.inputText1.value}"
                                to="#{backing_start.paramToPass}"/>
        </af:commandButton>
      </af:form>It references a bean that has this:
    private RichInputText inputText1;
    public void setInputText1(RichInputText inputText1) {
        this.inputText1 = inputText1;
    public RichInputText getInputText1() {
        return inputText1;
    public String paramToPass;
    public void setParamToPass(String paramToPass) {
        this.paramToPass = paramToPass;
    public String getParamToPass() {
        return paramToPass;
    }And then I can see it in the next page that I navigated to like this:
        <af:outputText value="the current value is #{backing_start.paramToPass}"/>In the adf-config.xml I have this:
<adfc-config xmlns="http://xmlns.oracle.com/adf/controller" version="1.2">
<view id="start">
    <page>/start.jspx</page>
</view>
<view id="end">
    <page>/end.jspx</page>
</view>
<control-flow-rule>
    <from-activity-id>start</from-activity-id>
    <control-flow-case>
      <from-outcome>go</from-outcome>
      <to-activity-id>end</to-activity-id>
    </control-flow-case>
</control-flow-rule>
<managed-bean>
    <managed-bean-name>backing_start</managed-bean-name>
    <managed-bean-class>backing.backing_start</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
</managed-bean>
</adfc-config>

Urgent - can't set managed bean value using a form, getting null

I have a form with a bean -- unbelievably, I can't get the values entered into the form by the user to get stored into the bean. Everything is null... I've looked at a zillion examples, posts and compared etc...yet still can't see what is missing.
Here's part of a trace :
[cc]Dec-31 01:25:02 ApplicationImpl - Created bean resourceBean successfully
[cc]Dec-31 01:25:02 ApplicationImpl - Storing resourceBean in scope request
[cc]Dec-31 01:25:02 VariableResolverImpl - resolveVariable: Resolved variable:id=null name=null
[cc]Dec-31 01:25:02 ValueBindingImpl - getValue Result:id=null name=null
[cc]Dec-31 01:25:02 ValueBindingImpl - -->Returning id=null name=null
If you have any ideas, please let me know--it seems just as I solve one JSF issue, I run into another on unexpectedly simple things.
Here's the ResourceBean.java, the bean-config.xml and my jsp.

I solved this.
Since I was testing the action code only, I didn't define a navigation entry corresponding to the action string returned for this button:
<h:commandButton value="Add" style="height:21px; width:51px;font-size:8pt; font-color: black;" action="#{resourceBean.addAction}">
</h:commandButton>After I added a nav definition, it worked. I don't know why at this point. I suspect a key step in the lifecycle was pre-empted...someone else can probably explain why. If I get a chance to research it after I'm done with my project, I'll update this post.
Thanks.

Get the current value of a managed bean.

Hi guys
I have a register page which takes the Login ID and the password and retype password whose values are stored in the "Managed Beans" in registerServer.java.
I have a (PwdValidator.java) Custom validator for Re-type Password which validates itself against the password.
Now my problem is from the PwdValidator.java how can I access the value of the password which is stored in the managed bean in registerServer.java.
here is a copy of my faces-config.xml
     <managed-bean>
          <managed-bean-name>registerServer</managed-bean-name>
          <managed-bean-class>com.sun.registerServer</managed-bean-class>
          <managed-bean-scope>session</managed-bean-scope>
     </managed-bean>
Help is really appreciated,
Thanks,
Chaprasi Baba

Thanks for the reply but my question is how do I get
the password value from the managed bean
FacesContext context =
FacesContext.getCurrentInstance();
Application application = context.getApplication();
CountryValueObject registerServer =
(CountryValueObject)application.getVariableResolver().r
solveVariable(context, "registerServer");
String pwd = registerServer.password // So will this
give me the current value for that session.You didn't go far enough in replacing the example code . Try this:
FacesContext context = FacesContext.getCurrentInstance();
Application application = context.getApplication();
RegisterServer registerServer = (RegisterServer)application.getVariableResolver().resolveVariable(context, "registerServer");
String pwd = registerServer.password // So will this give me the current value for that session.

Problem with Action binding for a command button in a Managed Bean

Hi
Thank you for reading my post
I am trying to use a backing bean for a button action binding.
I followed all steps as they seems to be correct. i did not made any changes directly by hand , all of changes are introduced by oracle
Jdeveloper wizards. but now i get this exception
Managed bean is defined in faces-config.xml (it shows in preview mode) , the method is there in managed bean (Jdeveloper itself create the method i just enter its name)
can you please take a look and tell me what can be wrong?
thanks
here is method and its body in managed bean
public String userAccept_action() {
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("Commit");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;
    }here is the exception that i recive

Thank you for reply , but it does not helps or maybe i did not apply it correctly
here is faces-config.xml code snippet :
<managed-bean>
    <managed-bean-name>ButtonActions</managed-bean-name>
    <managed-bean-class>webui.common.actionListener.ButtonAction</managed-bean-class>
    <managed-bean-scope>session</managed-bean-scope>
    <managed-property>
      <property-name>bindings</property-name>
      <value>#{bindings}</value>
    </managed-property>
</managed-bean>here is binding for the button in jsp file :
<af:commandButton
                                text="#{res['button.accept']}"
                                disabled="#{!bindings.Commit.enabled}"
                                action="#{ButtonActions.userAccept_action}"/>and here is some code portion of ButtonAction class
package webui.common.actionListener;
import oracle.binding.BindingContainer;
import oracle.binding.OperationBinding;
public class ButtonAction {
    private BindingContainer bindings;
    public ButtonAction() {
    public BindingContainer getBindings() {
        return this.bindings;
    public void setBindings(BindingContainer bindings) {
        this.bindings = bindings;
    public String userAccept_action() {
        BindingContainer bindings = getBindings();
        OperationBinding operationBinding =
            bindings.getOperationBinding("Commit");
        Object result = operationBinding.execute();
        if (!operationBinding.getErrors().isEmpty()) {
            return null;
        return null;
}and i still get the same error.

ADF Faces: How to get the ADF BindingContainer in a managed bean?

Hi,
I not sure how to get the BindingContainer instance from inside of a managed bean method. I have tried the following config, but it does not work in all situations.
<managed-bean>
    <managed-bean-name>backing_showBooks</managed-bean-name>
    <managed-bean-class>view.backing.ShowBooks</managed-bean-class>
    <managed-bean-scope>request</managed-bean-scope>
    <managed-property>
      <property-name>bindingContainer</property-name>
      <property-class>oracle.adf.model.binding.DCBindingContainer</property-class>
      <value>#{bindings}</value>
    </managed-property>
    
</managed-bean>When an ActionListener- method of my ShowBooks bean is called the property bindingContainer is NULL!!
Is there a save way to get the BindingContainer in my bean??
Any hints are welcome.
Thanks,
Markus

Maybe I just need another pair of eyes but when I set this up as explained and watch it in the debugger my method public void setBindingContainer(DCBindingContainer bc) gets called but bc is null. Can anyone help?
Thanks
Backing Bean-
private DCBindingContainer bindingContainer;
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
public DCBindingContainer getBindings() {
return bindingContainer;
