**URGENT** Hide/Show component on JSpliPane

Question

Hi,
I have a JFrame and a Jsplit pane on it and a toolbar.I want to make one button of the toolbar to show/hide the left-top/right-bottom component of the splitpane.I used the following code on actionedPerformed of the button. The code works but the divider is disapeared after first hide of a component.
int l_lastDividerLocation = splitpane.getDividerLocation();
int l_lastOrientation = splitpane.getOrientation();
splitpane.removeAll();
splitpane.setOrientation(l_lastOrientation);
if(m_firstComponent != null && m_firstComponent.mb_showComponent == true){
// m_firstComponent.setSize(m_firstComponentSize);
splitpane.add(m_firstComponent);
if(m_secondComponent != null && m_secondComponent.mb_showComponent == true){
// m_secondComponent.setSize(m_secondComponentSize);
splitpane.add(m_secondComponent);
splitpane.setOneTouchExpandable(true);
splitpane.setDividerLocation(l_lastDividerLocation);

You could invoke the initialization method during on load of the page fragment as follows:
Assume that you have the view SampleView.jsff:
SampleView.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">
<af:outputText value="#{pageFlowScope.InitializationText}" id="ot1"/>
</jsp:root>
SampleViewPageDef.xml:
<?xml version="1.0" encoding="UTF-8" ?>
<pageDefinition xmlns="http://xmlns.oracle.com/adfm/uimodel" version="11.1.2.60.17" id="SampleViewPageDef"
Package="com.subbanasolutions.view.pageDefs"
ControllerClass="com.subbanasolutions.view.bean.SampleViewBean">
<parameters/>
<executables>
<variableIterator id="variables"/>
</executables>
<bindings/>
</pageDefinition>
SampleViewPageBean.java:
package com.subbanasolutions.view.bean;
import oracle.adf.model.RegionBinding;
import oracle.adf.model.RegionContext;
import oracle.adf.model.RegionController;
import oracle.adf.view.rich.context.AdfFacesContext;
public class SampleViewBean implements RegionController {
public SampleViewBean() {
super();
@Override
public boolean refreshRegion(RegionContext regionContext) {
int refreshFlag = regionContext.getRefreshFlag();
if (refreshFlag == RegionBinding.PREPARE_MODEL) {
// Invoke Initialization method
System.out.println(":::: Initialization Method Invoked");
this.initializeMethod();
regionContext.getRegionBinding().refresh(refreshFlag);
return false;
@Override
public boolean validateRegion(RegionContext regionContext) {
regionContext.getRegionBinding().validate();
return false;
@Override
public boolean isRegionViewable(RegionContext regionContext) {
return false;
@Override
public String getName() {
return null;
public void initializeMethod() {
// HAVE YOUR CUSTOM LOGIC
