Hi,
My requirement is i want to render a message, as a popup or something, as soon as page is rendered.
The thing is I dont have any events for this.

If SampleView1 is a pageFragment with in a Taskflow, the following sample how you could show the initilization message.
SampleView1.jsff:
<?xml version='1.0' encoding='UTF-8'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.1"
xmlns:af="http://xmlns.oracle.com/adf/faces/rich"
xmlns:f="http://java.sun.com/jsf/core">
<af:panelFormLayout id="pfl1">
<f:facet name="footer"/>
</af:panelFormLayout>
</jsp:root>
SampleView1PageDef.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel"
version="11.1.1.59.23" id="SampleView1PageDef"
Package="view.pageDefs"
ControllerClass="view.bean.FragmentLifeCycleListener">
<parameters/>
<executables>
<variableIterator id="variables"/>
</executables>
<bindings/>
</pageDefinition>
FragmentLifeCycleListener.java:
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import oracle.adf.model.RegionBinding;
import oracle.adf.model.RegionContext;
*public class FragmentLifeCycleListener implements oracle.adf.model.RegionController {*
public FragmentLifeCycleListener() {
super();
*public boolean refreshRegion(RegionContext regionContext) {*
int refreshFlag = regionContext.getRefreshFlag();
*if (refreshFlag == RegionBinding.PREPARE_MODEL) {*
FacesContext fctx = FacesContext.getCurrentInstance();
FacesMessage message =
new FacesMessage("Welcome to exciting world of ADF");
fctx.addMessage(null, message);
*// Propagate the refresh to the inner binding container*
regionContext.getRegionBinding().refresh(refreshFlag);
return false;
public boolean validateRegion(RegionContext regionContext) {
// Propagate the validate to the inner binding container
regionContext.getRegionBinding().validate();
return false;
public boolean isRegionViewable(RegionContext regionContext) {
return false;
public String getName() {
return null;
