h:outputScript with target="head" not working with Primefaces 3.5

Question

I have a JSF application with some scripts inserted using target="head" attribute, but after including Primefaces 3.5 to the classpath, these scripts stop rendering.

Here is the page code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" 
      xmlns:ui="http://java.sun.com/jsf/facelets" 
      xmlns:h="http://java.sun.com/jsf/html" 
      xmlns:f="http://java.sun.com/jsf/core">
 <h:head> 
 </h:head>
   <h:body>
       <h:outputScript  target="head">
          function a(){};
        </h:outputScript>
 </h:body>
</html>

Removing the target attribute renders the script ok, but in the body, not in the head...

Any clues? Thanks & Regards.

Note, I tried Primefaces 3.0 and newer and the problem persists, but PrimeFaces 2.2.1 works properly. — Rafael Sisto, Jul 11 '13 at 00:51

Since PrimeFaces 3.0, there is a new HeadRenderer which allows customizable resource ordering. See also this blog. This has overriden the standard JSF head renderer. This is at its own okay, but apparently it failed to properly recognize inline scripts with target of head. This is clearly a bug in PrimeFaces head renderer. Your best bet is to report this issue to PF guys.

In the meanwhile, if you aren't making use of that new PrimeFaces feature at all, then just put Mojarra's own HeadRenderer back as default head renderer by adding the following entry to faces-config.xml:

<render-kit>
    <renderer>
        <component-family>javax.faces.Output</component-family>
        <renderer-type>javax.faces.Head</renderer-type>
        <renderer-class>com.sun.faces.renderkit.html_basic.HeadRenderer</renderer-class>
    </renderer>
</render-kit>

Note: in case you're using MyFaces instead of Mojarra, obviously reference MyFaces own one instead.
