Then you're doing something odd :-) If you have dependencies like this:
CustomComponent --> Custom JS Reference (and this is added in the public void renderHead( Component component, IHeaderResponse response ) method) --> Wicket's JQuery JS Reference Page A (no Ajax components or components depending on Wicket's jquery ref) Page B --> CustomComponent (Page B being a copy of Page with a single instance of your CustomComponent) When you load Page A, the JS will not be loaded. When you load Page B, both the Wicket JS and the custom JS will be added to the page. If you are seeing Jquery being loaded in Page A then some component on that page requires the Wicket JS libraries and is causing it to be added.
