OAF: Create Switcher Bean in a table dynamically/programmatically

In some cases we need to create a Switcher Bean in existing OAF Pages. We can add this switcher bean programmatically using an extended controller. Sample code is given below:

 private void addDeleteSwitcher(OATableBean tableBean, OAPageContext pageContext)  
  {  
   OASwitcherBean deleteSwitcher = (OASwitcherBean)tableBean.findChildRecursive("DELETE_SWITCHER");  
   if (deleteSwitcher == null)  
   {  
    /*  
     * Create Delete Bean Enabled  
     */  
    OAImageBean deleteBean = (OAImageBean)createWebBean(pageContext, OAWebBeanConstants.IMAGE_BEAN, null,"DELETEROW");  
    Hashtable paramsWithBinds = new Hashtable(1);  
    paramsWithBinds.put("xxPlanIdParam", new OADataBoundValueFireActionURL(deleteBean, "{$PLAN_ID}"));  
    deleteBean.setFireActionForSubmit("DeleteRow",null,paramsWithBinds,true,true);  
    deleteBean.setSource(OAWebBeanConstants.APPS_MEDIA_DIRECTORY + "deleteicon_enabled.gif");  
    deleteBean.setShortDesc("Delete this row from the Quality Plan Results");  
    deleteBean.setLabel("Delete");  
    deleteBean.setHAlign(OAWebBeanConstants.H_ALIGN_CENTER);  
    /*  
     * Create Delete Bean Disabled  
     */  
    OAImageBean deleteBeanDisabled = (OAImageBean)createWebBean(pageContext, OAWebBeanConstants.IMAGE_BEAN, null,"DELETEROWDISABLED");  
    deleteBeanDisabled.setSource(OAWebBeanConstants.APPS_MEDIA_DIRECTORY + "deleteicon_disabled.gif");  
    deleteBeanDisabled.setShortDesc("Plan Result has been transferred to EAM and cannot be deleted");  
    deleteBeanDisabled.setLabel("Delete");  
    deleteBeanDisabled.setHAlign(OAWebBeanConstants.H_ALIGN_CENTER);  
    /*  
     * Create Switch Bean  
     */  
    deleteSwitcher = (OASwitcherBean)createWebBean(pageContext, OAWebBeanConstants.SWITCHER_BEAN,null,"DELETE_SWITCHER");  
    deleteSwitcher.setNamedChild("N",deleteBean);  
    deleteSwitcher.setLabel("Delete");  
    deleteSwitcher.setNamedChild("Y",deleteBeanDisabled);  
    deleteSwitcher.setViewUsageName("ViewResultsVO");  
    deleteSwitcher.setViewAttributeName("DeleteSwitcherAttribute");   
    deleteSwitcher.setRendered(true);  
    tableBean.addIndexedChild(deleteSwitcher);  
   }  
  }
