Major Description
In Wicket 1.4.1, 1.4.2 there is an inconsistency in rendering resource path (eg. for css) when we are using <wicket:link> tag in HTML and HeaderContributor in Java code.
When we enter a page with a linked resource (using: <wicket:link>):
...
<head>
<title>Wicket Quickstart Archetype Homepage</title>
<wicket:link>
<link href="main.css" rel="stylesheet" type="text/css" media="screen, projection"/>
</wicket:link>
</head>
...
for the very first time (after starting application), a link for main.css is rendered as:
<link href="resources/com.mycompany.HomePage/main.css" rel="stylesheet" type="text/css" media="screen, projection"/>
But after the second request this link is always rendered as:
<link href="resources/com.mycompany.HomePage/main_locale.css" rel="stylesheet" type="text/css" media="screen, projection"/>
where "_locale" is your current locale string (eg. "_pl", "_de", ...)
So the locale string is appended to the resource path. In Wicket 1.3.6 the path is always without locale.
You can try attached quickstart-app to see the difference.
When we replace <wicket:link> in html, with CSSPackageResource.getHeaderContribution in code:
add(CSSPackageResource.getHeaderContribution(HomePage.class, "main.css"));
this link is always rendered as:
<link rel="stylesheet" type="text/css" href="resources/com.mycompany.HomePage/main.css" />
Well I think both ways: using <wicket:link> or header contribution in code, should produce always the same url path for resource and it should not contain "_locale" suffix (as in Wicket 1.3.6).
