Re: Conditionally include header item when page contains ajax components
If I'm not mistaken this will cause JQuery to be included whenever my js reference is included. Effectively this will cause non-ajax pages to load javascript which applies only to ajax requests.

Re: Conditionally include header item when page contains ajax components
The javascript will only be included if your Ajax enabled component is included that in turn references the JS ResourceReference, otherwise it wont be.

Re: Conditionally include header item when page contains ajax components
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.
