docs: Used to close the current JSP dialog.<p>
  
  This method overwrites the close dialog method in the super class,
  because in case a new folder is created, after this dialog a new xml page might be created.<p>
  
  It tries to include the URI stored in the workplace settings.
  This URI is determined by the frame name, which has to be set
  in the framename parameter.<p>
  
  @throws JspException if including an element fails
