Non-database/Non-VO based ADF table: need programmaticall access! 11g

Question

Hello there,
I have ADF table with 2 attributes coming from a managed-bean. The table lies within *.jsff page in popup panelWindow. I am able to populate the table from the managed-bean after performing some actions.
My question is:
How to  get access to the selected row of that table programmatically? Since I want to perform delete of the selected row (including the values from the managed-bean corresponding to the selected row).
One of the table attributes contains unique values, but is not set as PK. I don't know if it is necessary to set that attribute to behave as PK. If yes, how do I achieve that, since is not VO-based table ?
Thanks a lot.
Regards,
Valon

Hi,
I would like to know how to populate af:table from a managed bean:
This is what I am trying:
There is a managed bean: StudentBean.java
This is registered in adf-config.xml as ADFStudentBean and also registered in faces-config.xml as JSFStudentBean.
Now I create a jspx page and create a JSF dataTable which I bind to JSFStudentBean. This works fine.
Next I create an ADF table and try to bind it to ADFStudentBean. It does not get bound since the columns are not appearing in the binding.
So I try to bind it to JSFSudentBean. This one works. But it throws a runtime exception:
This message may be avoided by performing initADFContext before using getCurrent().
<RegistrationConfigurator><handleError> Server Exception during PPR, #1
javax.servlet.ServletException: java.lang.StackOverflowError
at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:333)
at weblogic.servlet.internal.TailFilter.doFilter(TailFilter.java:26)
The steps are as follows:
1. Create Student.java
2. Create StudentBean.java
3. Register StudentBean.java as JSFStudentBean in faces-context.xml in request scope.
4. Register StudentBean.java as ADFStudentBean in adf-config.xml in request scope.
5. Create jspx file: Use f:dataTable like:
<h:dataTable value="#{JSFStudentBean.studentData}" var="var" id="dt1">
<!--oracle-jdev-comment:Faces.RI.DT.Class.Key:oracle.apps.view.Student-->
<h:column id="c3">
<f:facet name="header">
<h:outputText value="Stud Name" id="ot3"/>
</f:facet>
<h:outputText value="#{var.studName}" id="ot4"/>
</h:column>
<h:column id="c2">
<f:facet name="header">
<h:outputText value="Stud Roll" id="ot5"/>
</f:facet>
<h:outputText value="#{var.studRoll}" id="ot1"/>
</h:column>
<h:column id="c1">
<f:facet name="header">
<h:outputText value="Stud Class" id="ot6"/>
</f:facet>
<h:outputText value="#{var.studClass}" id="ot2"/>
</h:column>
</h:dataTable>
This works well.
6. Create af:table and try to bind it to "#{ADFStudentBean.studentData}
Does not work. The columns do not come in the create table wizard.
7. Hence I create af:table and bind it to #{JSFStudentBean.studentData}"
"<af:table value="#{JSFStudentBean.studentData}" var="row"
rowBandingInterval="0" id="t1">
<af:column sortable="false" headerText="Stud Name" align="start"
id="c1">
<af:outputText value="#{row.studName}" id="ot1"/>
</af:column>
<af:column sortable="false" headerText="Stud Roll" align="start"
id="c3">
<af:outputText value="#{row.studRoll}" id="ot3"/>
</af:column>
<af:column sortable="false" headerText="Stud Class" align="start"
id="c2">
<af:outputText value="#{row.studClass}" id="ot2"/>
</af:column>
</af:table>"
Bindings work but fails with the servletException

public class StudentBean {

public StudentBean() {
studentData = new ArrayList <Student> ();
studentData.add(new Student("Rakesh", 23, "Six"));
studentData.add(new Student("Hari", 12, "Two"));
studentData.add(new Student("Rajesh", 61, "Five"));
public void setStudentData(List<Student> studentData) {
this.studentData = studentData;
public List<Student> getStudentData() {

Please tell me why am I not able to use af:table and the managed bean registered in adf-config.xml?
Thanks,
