Package org.apache.wicket.markup.renderStrategy

Class ChildFirstHeaderRenderStrategy

java.lang.Object

org.apache.wicket.markup.renderStrategy.AbstractHeaderRenderStrategy

org.apache.wicket.markup.renderStrategy.ChildFirstHeaderRenderStrategy

All Implemented Interfaces:

IHeaderRenderStrategy

public class ChildFirstHeaderRenderStrategy
extends AbstractHeaderRenderStrategy

This a header render strategy implements a child->parent->root sequence, which is inverse to how it was until Wicket 1.5. It now allows parent containers to replace child contributions, since their contribution is added to the markup after the child ones (see WICKET-2693). Please note that irrespective of the render strategy, if the same header content (e.g. CSS file) gets added twice to the header, only the first will be rendered and the 2nd will be skipped.
