Class ExtendedOpenCloseTagExpander

  extended by org.apache.wicket.markup.parser.AbstractMarkupFilter
      extended by org.apache.wicket.markup.parser.filter.OpenCloseTagExpander
          extended by org.apache.wicket.markup.parser.filter.ExtendedOpenCloseTagExpander
All Implemented Interfaces:

public class ExtendedOpenCloseTagExpander
extends OpenCloseTagExpander

MarkupFilter that expands all xhtml tag which are open-close in the markup but where the standard requires it to have a body. See WICKET-2650 for another use case where you want to avoid situations where your java code wants to render a body text, but because of the open-close tag Wicket's render engine will not call onComponentTagBody(). And you'll not get a warning or exception. This filter is not added by default. You may add it like:

 Application#init() {
   getMarkupSettings().setMarkupParserFactory() {
      new MarkupParserFactory() {
        MarkupParser newMarkupParser(final MarkupResourceStream resource) {
                  MarkupParser parser=super.newMarkupParser(resource);
            parser.appendMarkupFilter(new ExtendedOpenCloseTagExpander());
            return parser;
You may subclass ExtendedOpenCloseTagExpander and implement your own contains(String) to throw an exception or log a warning instead of changing open-close to open-body-close.
