What is the prefered way to replace removed HeaderContributors in Wicket 1.5?
The migration guide says:
Wicket 1.4:
public class MyPage extends WebPage {
public MyPage() {
add(HeaderContributor.forCss(AbstractCalendar.class,
"assets/skins/sam/calendar.css"));
}
}
becomes in Wicket 1.5:
public class MyPage extends WebPage {
public MyPage() {
}
public void renderHead(IHeaderResponse response) {
response.renderCSSReference(new
PackageResourceReference(AbstractCalendar.class,
"assets/skins/sam/calendar.css"));
}
}
So I did in my classes.
My working class in Wicket 1.4 looks like:
public class DoctypeTestPage extends WebPage
{
public static final ResourceReference TEST_CSS = new
ResourceReference(DoctypeTestPage.class, "test.css");
public DoctypeTestPage( final PageParameters parameters )
{
super( parameters );
add(CSSPackageResource.getHeaderContribution( TEST_CSS ) );
...
}
}
The same class in Wicket 1.5 looks like:
public class DoctypeTestPage extends WebPage
{
public static final ResourceReference TEST_CSS = new
PackageResourceReference(DoctypeTestPage.class, "test.css");
public DoctypeTestPage( final PageParameters parameters )
{
super( parameters );
}
@Override
public void renderHead(final IHeaderResponse response)
{
response.renderCSSReference( TEST_CSS );
}
}
I've noticed with Tamper Data, that with Wicket 1.5 the content type of the
css-Resource is "text/html" instead of "text/css" with Wicket 1.4!!! This
causes the browser to switch into quirks mode in order to render the request
properly. The used markup header-tag is:
<html
xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";>
If I add the following Doctype declaration to the markup file, the browser
would never change into quirks mode, but also the CSS resource is not found
anymore.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
< html xmlns="http://www.w3.org/1999/xhtml";
xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd";
xml:lang="en"
lang="en">
Do I miss something? Or is this a bug with Wicket 1.5?
