[Trinidad] tr:fileDownloadActionListener error

[William Hoover]

Using the tr:fileDownloadActionListener inside a tr:column I get the a 
javax.servlet.ServletException: Invalid index after the download completes and 
another link is clicked on the page. Has anyone experienced this?

Page:

  <tr:commandLink text="Download file">
    <tr:sendFileActionListener
       mimeType="application/pdf" fileName="#{myBean.fileName}"
       sendFileListener="#{myBean.sendFile}"/>
  </tr:commandLink>

Bean:

        public void sendFile(FacesContext context, OutputStream out) throws 
IOException {
                OutputStreamWriter w = new OutputStreamWriter(out, "UTF-8");
                w.write("Test");
                w.flush();
        }
