How to make a page in read only

Question

Hello,
I am using 11.1.1.4, I am having a requirement to display all the components on my page read only when first time page loaded, By clicking on 'Edit' button I have to make all components in editable. I am using Transient View object to render various components on my page. I have 50 components approximately on my page. How can I make page read only with very minimal changes?
Thanks

Try something like that:
        public static void disableControls(UIComponent component, Object[] disabledParam) {
           Iterator<UIComponent> i = component.getFacetsAndChildren();
           while (i.hasNext()) {
                 UIComponent child = (UIComponent) i.next();
                 Class mc = child.getClass();
                  try {
                     Class[] cls = {boolean.class};
                     Method setDisabled = mc.getMethod("setDisabled", cls);
                     setDisabled.invoke(child, disabledParam);
                     AdfFacesContext.getCurrentInstance().addPartialTarget(child);                 
                  } catch(NoSuchMethodException ex){
                  } catch(Exception e) {
                     log.error(...);
                 disableControls(child, disabledParam);
           } // of while      
        }if you pass {Boolean.TRUE} as second param, you will disable all children of first param component.
Next, in the JSF page, yuo need something like follows:
        <af:clientListener type="load" method="onPageLoad"/>     
        <af:serverListener type="disable" method="#{myBean.handleDisable}"/>
    </af:document> The javaScript part:
function onPageLoad(event) {
  var source = event.getSource();
  AdfCustomEvent.queue(source,"disable", {}, false);
}And finally , here is handleDisable() Java method, in which you should call disableControls() utility method:
    public void handleDisable(ClientEvent event) {
        disableControls(_some_UI_comp, new Object[]{Boolean.TRUE});
    }
