Loading a region at click on the PanelBox

Question

Hi,
I have a PanelBox in the iterator . I would be load at the click on the PanelBox, the corresponding region.
Does anyone have any idea how to do that is? My code:
<af:iterator id="myIt1"
                                     value="#{bindings.MyView1.collectionModel}"
                                     var="row"
                                     rows="#{bindings.MyView1Iterator.rangeSize}" varStatus="stat">
                <af:panelBox id="myPanelB"   text="#{row.Ref}">
                            <af:componentDragSource/>
                            <af:outputText id="text1"   value="#{row.Description}"/>
                            <af:outputText id="text2" value="#{row.Address}"/>
                  </af:panelBox>
</af:iterator>Thanks in Advance
regards

Answer 1

you can access the var variable in the iterator in the managed bean.
Below is the sample based on the Departments Table in HR Schema.
IteratorSample.JSPX:
<af:form id="f1">
<af:iterator value="#{bindings.Departments.collectionModel}" var="row"
rows="#{bindings.Departments.rangeSize}" id="t1">
<af:outputText value="#{IteratorSampleBean.departmentValue}" id="ot1"/>
<af:spacer height="5" id="s1"/>
</af:iterator>
</af:form>
IteratorSamplePageDef.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
version="11.1.1.59.23" id="IteratorSamplePageDef"
Package="view.pageDefs">
<parameters/>
<executables>
<variableIterator id="variables"/>
<iterator Binds="Departments" RangeSize="25"
DataControl="AppModuleDataControl" id="DepartmentsIterator"/>
</executables>
<bindings>
<tree IterBinding="DepartmentsIterator" id="Departments">
<nodeDefinition DefName="model.views.DepartmentsVO">
<AttrNames>
<Item Value="DepartmentName"/>
</AttrNames>
</nodeDefinition>
</tree>
</bindings>
</pageDefinition>
IteratorSampleBean.java:
import javax.el.ELContext;
import javax.el.ExpressionFactory;
import javax.el.ValueExpression;
import javax.faces.context.FacesContext;
import oracle.jbo.Row;
import oracle.jbo.uicli.binding.JUCtrlHierNodeBinding;
public class IteratorSampleBean {
public IteratorSampleBean() {
super();
private String departmentValue;
public void setDepartmentValue(String departmentValue) {
this.departmentValue = departmentValue;
public String getDepartmentValue() {
JUCtrlHierNodeBinding node =
(JUCtrlHierNodeBinding)this.evaluateEL("#{row}");
if (node != null) {
Row currentRow = node.getRow();
if (currentRow != null) {
departmentValue =
(String)currentRow.getAttribute("DepartmentName");
return departmentValue;
private Object evaluateEL(String el) {
FacesContext facesContext = FacesContext.getCurrentInstance();
ELContext elContext = facesContext.getELContext();
ExpressionFactory expressionFactory =
facesContext.getApplication().getExpressionFactory();
ValueExpression exp =
expressionFactory.createValueExpression(elContext, el,
Object.class);
return exp.getValue(elContext);
}
