coldfusion 8,cfdocument, cfpdf, watermark, blank page output?

Question

I'm using cfdocument. No matter whether I use PDF or
Flashpaper as the type, if I specify the "name" attribute it
results in an outputted page that is blank. If I remove the name
attribute, it renders the pdf or flashpaper page.

Why is this happening? I want to use it to create a PDF
onscreen and then add a watermark to the just generated PDF, but
the cfpdf action="addWatermark" requires you to specify the name of
the pdf to add the watermark to. Since I cannot set the name, I
can't add the watermark.

What can I do? Thanks.

It is so by design in the cfdocument as well as in the cfpdf tag. If you specify a name attribute, Coldfusion wont display the PDF or Flashpaper output, but will hold it in memory as a variable.

To do the watermark with cfpdf action="addWatermark" you must specify the source attribute. That implies that, in the cfdocument that goes before, you should save the PDF as a file.

Here is an example. Coldfusion will create myTestDoc.pdf and store it in the current directory. For the watermark, I wish to use an image stored in the same directory. Coldfusion will then store the watermarked result as the file myWatermarkedDoc.pdf. The browser will only display the text PDF doc watermarked and saved as file.
