Leonardo Uribe commented on MYFACES-3106:
-----------------------------------------
I tried the demo and at first time I thought it was a bug. Use <ui:include
src="#{guiMB.viewID}> causes new resources to be loaded on the page. Obviously
in this case we have resources equivalent to:
<h:outputStylesheet target="head" .... >
When the action is executed, only the content is rendered. But even using the
standard f:ajax render="@all", the style links are not loaded, but the scripts
are executed. Really it is a problem in HTML and browser support itself. Once
the page is loaded, there is no way to update the <head> section using
javascript. I tried to fix this from server side, but it is useless, because
there is no way to fix the client side part.
In AjaxResponse.js you can found the following comments:
case this.P_VIEWHEAD:
//we cannot replace the head, almost no browser
allows this, some of them throw errors
//others simply ignore it or replace it and destroy
the dom that way!
/**
* replaces a current head theoretically,
* pratically only the scripts are evaled anew since nothing else
* can be changed.
*
* @param request the current request
* @param context the ajax context
* @param newData the data to be processed
*
* @return an xml representation of the page for further processing
if possible
*/
_replaceHead: function(request, context, newData) {
The only workaround in ensure all necessary css and js files are loaded on
<head> section, and again since ui:include src="#{...}" works on build view
time, the algorithm just don't know the views returned by such expression. So,
at the end the only alternative is let that to the developer. The same problem
will happen with all tags that affects dynamically the view like c:if or c:when.
Other alternatives are:
- Use a component that renders just one component from a child set like myfaces
commons mc:renderOne
- Force a GET or a full POST, instead ajax.
Since unfortunately this is a dead end, I'll close this one as invalid, because
we can't advance more at this point.

> Project: MyFaces Core
> Issue Type: Bug
> Affects Versions: 2.0.4
> Environment: Windows 7, JBoss AS 6, Richfaces 4.0.0 Final, JSF2
> Reporter: Luciano Deriu
> Attachments: Test.war

> I'm migrating my project from JSF 1.2 to JSF2 and I was using a <ui:include
> src="#{guiMB.viewID}" /> tag wrapped in a <a4j:outputPanel> tag (from
> RichFaces) and rendering the a4j:outputPanel via ajax. However in JSF2 this
> doesn't load the resources for the page i'm including.
> So anything i include dynamically like this doesn't have any of the styling
> or javascript that should be loaded with it.
> I have created a test project which demonstrates the issue so i'll attach for
> you to replicate the issue.
