That's really strange code. I would do something like this:

answerPdf
    self requestContext respond: [ :response |
        response
            contentType:'application/pdf'
            attachmentWithFileName:'usecase.pdf';
            binary;
            nextPutAll: thePdf ]


renderContentOn: html
    html anchor
        callback: [ self answerPdf ]
        with: 'donload PDF'

However that doesn't cover how the PDF is actually created. I have no
idea how PDFReactor works, does it render the current or an other page
as HTML send it to a server and get it back as PDF?
