Package org.apache.wicket.markup.renderStrategy

Class ParentFirstHeaderRenderStrategy

java.lang.Object

org.apache.wicket.markup.renderStrategy.AbstractHeaderRenderStrategy

org.apache.wicket.markup.renderStrategy.ParentFirstHeaderRenderStrategy

All Implemented Interfaces:

IHeaderRenderStrategy

public class ParentFirstHeaderRenderStrategy
extends AbstractHeaderRenderStrategy

This has been Wicket's default header render strategy before WICKET 1.5 which uses MarkupContainer.visitChildren(org.apache.wicket.util.visit.IVisitor) to traverse the hierarchy to render the children headers. Since child contributions are added to the markup after the parent contributions, children may replace / modify existing settings. Which is not good. Instead the parent (container) should be in control (see WICKET-2693).
