JSF 2.0 and dojo create NO_MODIFICATION_ALLOWED_ERR: DOM Exception 7 on Safari

When testing our dojo facelets examples in Safari I realized that they don't work with Mojarra 2.0. After some investigation it turned out that Mojarra 2.0 sends a reponse-header Content-Type: application/xhtml+xml thus triggering a bug in Safari.With JSF 1.2 (also with Facelets) it was always Content-Type: text/html. The result is that Safari throws NO_MODIFICATION_ALLOWED_ERR on some DOM operations that are needed from the dojo side.

I added a Listener to set the Content-Type to text/html and - helas! - it works just fine.

public void beforePhase(PhaseEvent event) {
   FacesContext context = FacesContext.getCurrentInstance();
   ExternalContext extContext = context.getExternalContext();
   Object response = extContext.getResponse();
   if (event.getPhaseId() == PhaseId.RENDER_RESPONSE) {
        String contentType = "text/html; charset=UTF-8";
      if (response instanceof ServletResponse) {
         ((ServletResponse) response).setContentType(contentType);
      } else if (response instanceof RenderResponse) {
         ((RenderResponse) response).setContentType(contentType);
      }
   }
}
