wicket:head and ajax updates
Hi all,
I have following problem:
I have a panel with a wicket:head tag that contributes the <title> to a
page. The title is a simple Label.
Now the first time it renders without a problem.
When I navigate in my form, it sends an event that the title-label listens
to and adds itself to the target.
But in the HTML it never gets refreshed. Although I can see it in the
response with the updated value.
Also the same mechanism worked before when I had it on the page itself and
put it directly in the <head> section.
any ideas what I missed?
Kind regards,
Ravi

One difference I see in the response is that in my application the <title> is
contained in the <header-contribution> element (not working). Whereas in my
quickstart it is in the in an <component> element (working) as such:
Quickstart:
<code>
<?xml version="1.0" encoding="UTF-8"?>
<ajax-response>
<component id="browserTitlee" ></component></ajax-response>
<code>
My application:
<code>
<header-contribution></header-contribution>
</code>
any idea where I can start debugging or how to avoid this?
I also added an Ajaxlink in my application that send an event to my
Title-label and this works too!
I can not make out the where the difference lies, since the browserTitle
listens only to an event.
Any idea how to avoid this, or where I could start debugging?

Okay, my quickstart works as expected.
So the problem must be somewhere else in my code...
Thank you all for your quick response!

Hi Ravi,
a stupid question : are you sure the updated value is different from the original value ?

@Ernesto
I added the version to my post.
@Martin
It is present in the Ajax response as well as in the page markup.
The page renders correctly the first time. Only the Ajax update does not
occur in the head.
I'll try to strip it down somewhat.
Usually I don't use wicket:head. So I wasn't sure if I'm missing something.
You have a point there martin, but since this is a base component for
multiple applications, we try to keep the applications itself as lean as
possible.

Hi,
In the Ajax response there must be something like: <component
id="theTitleMarkupId"> and in your page html there must be <title
id="theTitleMarkupId".
If both of those are true then I don't see why it won't work.
But I personally won't put any components inside <wicket:head>.
What if two or more Panels contribute <title> in their <wicket:head> ?
