> Given code like the following, where same ResourceReference is used for both
> resources but they have different PageParameters and different IDs, only one
> of them actually gets rendered in the page head:
> {code}
> public void renderHead(IHeaderResponse response) {
> …
> response.render(JavaScriptHeaderItem.forReference(resRef,
> pageParameters1, “id1”));
> response.render(JavaScriptHeaderItem.forReference(resRef,
> pageParameters2, “id2”));
> }
> {code}
