HI,

this might be caused by ResourceAggregator - it marks items as being rendered, instead of render tokens.

I'll check tomorrow.

I have a situation like this:

public void renderHead(IHeaderResponse response) {
     …
     response.render(JavaScriptHeaderItem.forReference(resRef,
pageParameters1, “id1”));
     response.render(JavaScriptHeaderItem.forReference(resRef,
pageParameters2, “id2”));
}

where same ResourceReference is used for both resources – the different
page parameters point it to different actual Resources.

However, the check for uniqueness of header items seems to consider them
equal, despite the different PageParameters and different IDs, and only one
of them actually gets rendered in the page head.

Which check exactly do you refer ?

org.apache.wicket.markup.head.internal.HeaderResponse#markItemRendered()
does such check by calling org.apache.wicket.markup.head.HeaderItem#
getRenderTokens().
org.apache.wicket.markup.head.JavaScriptReferenceHeaderItem#getRenderTokens()
uses the url and the id. The url contains the parameters.
All looks good to me!

The other check is at jQuery.Head.containsElement() (wicket-ajax-jquery.js)
and it uses the value "src", i.e. it should not match because of the
different parameters.


Is this a bug, or is there a way to force the two items to both be
included?

I’m using Wicket 7.5.0.
