I tested all this in FF, IE, Opera. Not the question remains, how to ensure that on the same page the contribution will be only once. I suggest handling this on server side. Say you have component on a page (not visible). You render page (without the component). Then you render the component (using ajax). The header contribution will be rendered. After that on every subsequent ajax component render, the header contribution will not be rendered, until the whole page is refreshed (re-rendered). -Matej > > -Matej > > Johan Compagner wrote: >> if you add css or javascript to the head of the page at runtime in a >> dynamic way >> is it then seen in the browser?? >> We should first test that. >> >> johan >> >> >> On 7/5/06, * Matej Knopp* <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>> >> wrote: >> >> Hi >> >> There's a known problem with head contribution of components, that are >> not rendered when the whole page is (are hidden or not even part of >> hierarchy), but are additionally rendered using an AJAX call. >> >> The problem is, that while the body of the component is placed in the >> page, the head contribution is ignored. >> >> Any ideas on how should we address this issue? >> >> First I though that catching css links and javascript references from >> renderHead would be enough. >> >> But each component with associated markup can have it's own >> <wicket:head>, and this is something we also have take into account. >> >> So what I'm thinking of now is to let component render it's head to a >> buffer - it will probably be a xml snippet with structure like: >> >> <link rel="stylesheet" href="..."/> >> <style type="text/css"> >> ... >> </style> >> <script type="text/javascript" src="..."> >> <script type="text/javascript"> >> ... >> </script> >> >> If this snippet is well formed, I think we can send it as a part of our >> ajax response. >> e.g. >> >> <?xml version=" 1.0" encoding="UTF-8"?> >> <ajax-response> >> <component id="c1" > >> <![CDATA[<span id="c1">3</span>]]> >> </component> >> <head> >> <link rel="stylesheet" href="..."/> >> <style type="text/css"> >> ... >> </style> >> <script type="text/javascript" src="..."> >> <script type="text/javascript"> >> ... >> </script> >> </head> >> </ajax-response> >> >> >> The DOM structure of the head part should be quite straightforward to >> parse.
