incompatibility issues and the other common Ajax pitfalls. This section
focuses on the Dojo Toolkit.
The form is submitted asynchronously using Dojo, through Shale Remoting,
and the form is consumed by the FileUploadHandler. Registering
JavaScript Events on the Components After the page is rendered and the

The updateOnServer JavaScript function, which is mapped to this event,
creates an XMLHttpRequest object and configures it with the URL to the
FacesServlet instance.
I did not include the render option because I want all components to be
