Adding a JSF 2 compound component at run time from a backup bean

Question

Edited Question ...

Hello,

I would like to download the .xhtml file of my composite component from a bean backup and add it to the page dynamically. The name of the .xhtml file is in the form of a variable.

Example:.

public MyBean (){

    String componentFile = "myCompositeComponent.xhtml"

    public String addComponentToPage(){

          //how do that?...

          return null;
    }

} 

Thank!
