> 1. Create any components that is derived from MarkupContainer, for example, create Panel. 
> 2. Put some components to the Panel, for example, TextInput, Label etc.
> 3. Call panel.setEnabled(false) 
> Result: all controls on panel are still enabled.
> Notes: after some investigation I found that MarkupContainer doesn't override setEnabled and therefore it cannot enable/disable components stored in the container. 
> Workaround: manually disable all components that are displayed on the panel, for example:
> public void setEnabledForChildren(boolean enabled) {
>         setEnabledRecursive(this, enabled);
>     }
>     private void setEnabledRecursive(MarkupContainer container, boolean enabled) {
>         Iterator<? extends Component> iterator = container.iterator();
>         while (iterator.hasNext()) {
>             Component component = iterator.next();
>             component.setEnabled(enabled);
>             if (component instanceof MarkupContainer) {
>                 setEnabledRecursive((MarkupContainer) component, enabled);
>             }
>         }
>     }
> I think that MarkupContainer must be responsible for disabling/enabling child components.
