     * that we can instantiate an ExternalToolHandler) so we retrieve
     * externalTool from a transient variable in guestbookResponse if
     * externalTool is null. The current observation is that externalTool
     * is null from the dataset page and non-null from the file page. See
     * file-download-button-fragment.xhtml where the popup is launched (as
     * needed) and file-download-popup-fragment.xhtml for the popup itself.
     *
     * TODO: If we could figure out a way for externalTool to always be
     * non-null, we could remove this if statement and the transient
     * "externalTool" variable on guestbookResponse.
