All Implemented Interfaces:

IMarkupFilter

public class OpenCloseTagExpander
extends AbstractMarkupFilter

MarkupFilter that expands certain open-close tag as separate open and close tags. Firefox, unless it gets text/xml mime type, treats these open-close tags as open tags which results in corrupted DOM. This happens even with xhtml doctype. In addition, some tags are required open-body-close for Wicket to work properly.
