I'm using Mojarra 2.1 and RichFaces.
I have the following action method:
public String doSave() {
    //do some
    return "someView";
}
invoked by cliccking the
<a4j:commandButton action="#{theBean.doSave}" />
and the view-file someView.jspx. But after the action method has invoked I'm redirected to the appropriate view, but lose all css-styles in that view. Actually, the head tag of the page is empty:
<head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
</head>
The someView page bounded to a session-scoped bean.
I have really no idea about what it can be tied with? Need some advice.
BTW, it works perfectly fine with h:commandButton. Is it a richFaces bug?
