PrimeFacesScriptProcessor: Uncaught Synatx Error, Primefaces.settings rendered in SPAN

See original GitHub issue

When using the PrimeFacesScriptProcessor according to the Showcase you can see in the WebDev-Console “Uncaught SyntaxError: Unexpected token ‘<’” and when inspecting the webpage you see that the “Primefaces.settings”-Part is inside of a SPAN-tag, which seems to be the cause of the error. In the Showcase itself it is not visible, but there can also not see any Primefaces.settings in the head.

When using BalusC approach, the tag gets rendered as expected but after a click or ajax request, Mojarra throws excpetion caused by duplicated id in component.

Primefaces Extension Code

private void addJS(FacesContext context, String script) { String id = UUID.randomUUID().toString(); final UIOutput js = new UIOutput(); js.setId(“js-” + id + “1”); js.setRendererType(“javax.faces.resource.Script”); final UIOutput content = new UIOutput(); content.setId(“js-” + id + “2”); content.setValue(script); js.getChildren().add(content); context.getViewRoot().addComponentResource(context, js); }

Rendered HTML: <script type="text/javascript"><span id="js-a07c21e3-04b7-4063-b3eb-b570c6b974ee2">if(window.PrimeFaces)...</span></script>
