Hi Edvin,
The <body> tag from your subpage is discarded. The <body> tag that is
rendered comes from some parent page. One way to do this would be to
attach a WebMarkupContainer to the <body> tag in the parent page and
expose it via a getter:
public class ParentPage extends WebPage {
private WebMarkupContainer body;
public ParentPage() {
body = new WebMarkupContainer("body");
// need to add all children to the body tag
// instead of the page
}
protected WebMarkupContainter getBody() {
return body;
}
}
public class ChildPage extends ParentPage {
public ChildPage() {
getBody().add(new SimpleAttributeModifier("class", "foo"));
}
}
