is it then seen in the browser??
We should first test that.

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. The _javascript_ used to add stylesheet and _javascript_ to html head
does not seem difficult either.
Now the problem seems to be deciding, whether to apply the contribution,
or whether it has already been applied. We don't want to run the same
_javascript_ twice, etc.
How should this be solved? Any ideas?
