The suggestion provided by Timo Should work.
Here, is an sample based on Employees Table based on HR Schema.
Ensure that the selection listener for the table is selected as single.
JSPX Page:
<af:form id="f1">
<af:table value="#{bindings.Employees.collectionModel}" var="row"
rows="#{bindings.Employees.rangeSize}"
emptyText="#{bindings.Employees.viewable ? 'No data to display.' : 'Access Denied.'}"
fetchSize="#{bindings.Employees.rangeSize}"
rowBandingInterval="0"
*selectedRowKeys="#{bindings.Employees.collectionModel.selectedRow}"*
*selectionListener="#{bindings.Employees.collectionModel.makeCurrent}"*
*rowSelection="single"*
id="t1">
<af:column sortProperty="EmployeeId" sortable="true"
headerText="#{bindings.Employees.hints.EmployeeId.label}"
id="c4">
<af:outputText value="#{row.EmployeeId}" id="ot2">
<af:convertNumber groupingUsed="false"
pattern="#{bindings.Employees.hints.EmployeeId.format}"/>
</af:outputText>
</af:column>
<af:column sortProperty="FirstName" sortable="true"
headerText="#{bindings.Employees.hints.FirstName.label}"
id="c1">
<af:outputText value="#{row.FirstName}" id="ot3"/>
</af:column>
<af:column sortProperty="LastName" sortable="true"
headerText="#{bindings.Employees.hints.LastName.label}"
id="c3">
<af:outputText value="#{row.LastName}" id="ot4"/>
</af:column>
*<af:column headerText="#{'View Details'}" id="c2">*
*<af:commandButton text="View Details" id="cb1"*
*actionListener="#{SamplePageBean.onClick}"/>*
*</af:column>*
</af:table>
</af:form>
*Bean Code:*
import javax.faces.event.ActionEvent;
import oracle.adf.model.BindingContext;
import oracle.adf.model.binding.DCBindingContainer;
import oracle.adf.model.binding.DCIteratorBinding;
public class SamplePageBean {
public SamplePageBean() {
public void onClick(ActionEvent actionEvent) {
DCBindingContainer dcBindings =
(DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
// Get a attribute value of the current row of iterator
DCIteratorBinding iterBind =
(DCIteratorBinding)dcBindings.get("EmployeesIterator");
String firstName =
(String)iterBind.getCurrentRow().getAttribute("FirstName");
String lastName =
(String)iterBind.getCurrentRow().getAttribute("LastName");
System.out.println(firstName + " " + lastName);
