CF8 - Ajax Form Post and Document Type

Question

I'm having a problem trying to figure out how to get a form
post to return a PDF document using CF8. I can't seem to get
CFDOCUMENT to deliver a PDF through the form.
I have a form inside a CFDIV...
<cfdiv id="mydiv">
<cfform action="myscript.cfm" method="post">
a bunch of input fields, then...
<input type="submit" value="Generate PDF" />
</cfform>
</cfdiv>
On submit, the form makes an Ajax call sending the data to a
script that generates a PDF using CFDOCUMENT and delivers it
through the browser.
However, it is not delivering the PDF. Instead, it is
delivering the CODE for the PDF into the CFDIV and trying to
display the code. I tried the same form delivering an Excel file
with cfcontent and cfheader. It delivers the code instead of the
actual document.
If I take this form out of the CFDIV, everything works great.
Why can't the Ajax call made by the CFDIV functionality
deliver a PDF or other file?

Answer 1

I'm having the same problems over two years later. CFCONTENT
doesn't work as documented when you call it from within an AJAX
app. My workarounds that call the code from another directory are
way too kludgey for the client, but proved my standard code works
outside of AJAX layout areas. I'm specifically trying to do what
tSpark also mentioned, that is generate an Excel spreadsheet from
query results displayed in an HTML table.
Has anyone solved this problem?
