code: public void documentComponentClosed(DocumentComponentEvent event) {
  		if(logger.isDebugEnabled()){
  			logger.debug("Page component "+pageComponent.getId()+" closed");

docs: Default closed implementation removes the given page component from the
  workspace view, and so the document from the document pane.
