> When a request is made by from inside a a4j:include component UIInclude will set the ViewIdHolder to it self. It does this to ensure FacesContext.getCurrentInstance().getViewRoot().getViewId() returns the viewId of the a4j:include.
> Everything works fine if you only need to access the viewId when its already rendered and its posting back.
> If you, as I am, change the viewId of the UIInclude (the UIInclude is bound to a property of a managed bean), when the page is rendered back it renders the new "view" assigned to the UIInclude. When its rendered any manage-bean used from inside the a4j:include will see the viewId as the "outter view" not the view assigned to the a4j:include.
> I believe the simplest and best solution easiest solution is when rendering the children of uiinclude to:
> ---
> AjaxContext ajaxContext = AjaxContext.getCurrentInstance(context);
> ViewIdHolder viewIdHolder = ajaxContext.getViewIdHolder();   // Store reference to current
> ajaxContext.setViewIdHolder(this);  // This is UIInclude
> // render children here...
> ajaxContext.setViewIdHolder(viewIdHolder );  // Put previous back
> ---
