        response.render(OnDomReadyHeaderItem.forScript(buildRequireJsConfig(requireJsLibraries)));

Wicket contributes just one occurrence of some JS code. See https://github.com/apache/wicket/blob/0c4b88e16a3ec7478fbc8f86991c6b07805ed821/wicket-core/src/main/java/org/apache/wicket/markup/head/OnDomReadyHeaderItem.java#L101

To overcome it you can do either:

1. Add something unique to your JS code for each contribution. E.g. pass an unused function parameter with a unique name.

2. Override #getRenderTokens() for each header item:

   OnDomReadyHeaderItem item = new OnDomReadyHeaderItem(js) {

    @Override
    public Iterable<?> getRenderTokens()
    {
       return Collections.singletonList("javascript-domready-" + somethingUnique);
    }
   

somethingUnique could be anything that is unique, e.g. a timestamp or UUID
