File upload control

Dear List,

I have looked at the examples on the orbeon.com website to see how to do a
file upload.

The simple example:

http://www.orbeon.com/ops/xforms-sandbox/sample/upload-replace-instance

results in this content received by my (external) server:

<?xml version="1.0" encoding="UTF-8"?><file
xmlns:f="http://orbeon.org/oxf/xml/formatting"
xmlns:ev="http://www.w3.org/2001/xml-events"
xmlns:xforms="http://www.w3.org/2002/xforms"
xmlns:xhtml="http://www.w3.org/1999/xhtml"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:widget="http://orbeon.org/oxf/xml/widget"
xmlns:xxforms="http://orbeon.org/oxf/xml/xforms" filename="test1.csv"
mediatype="text/csv"
size="1062">file:/home/robin/Desktop/apache-tomcat-5.5.20/temp/xforms_upload_27124.tmp</file>

The crucial point being, I get the name of the file as from the Orbeon
cache, not  the file content.

The running code is exactly that from the Orbeon web site, except that I
changed the action attribute. The code is cut and pasted below for
convenience.

What could I be doing wrong? Anything to do with base64Binary?

The more complicated example involves xpl and processors. But I'm hoping
there is some way of uploading a file using just plain vanilla xforms
controls and constructs.

Many Thanks,

Robin

Exactly: what you have there now is the URI of a temporary file, which
I assume you can't access in your other application if it runs from
another server. So you want to tell the XForms engine to put the file
in base64 in the instance. You do this with an <xforms:bind
nodeset="points to your node" type="xs:base64Binary"/>. You can find
more about this on:
