Did you have a look at what I mailed you what's in my java code, page-flow
and .xpl? You might see a thing missing or something done wrong...
This is what is returned to the client from the java code I mailed you:

<?xml version="1.0" encoding="utf-8"?><xxf:event-response
xmlns:xxf="http://orbeon.org/oxf/xml/xforms"
><xxf:dynamic-state>pers:784A27F5-359A-CFA7-F395-2C0DFFDB57FB</xxf:dynamic-state><xxf:action><xxf:control-values
/></xxf:action></xxf:event-response>

so this indeed seems empy and I guess the logging of XFormsServer is
therefore correct:

WARN  XFormsServer  - XForms - submission - instance replacement did not
take place upon successful response because no body was provided.
Submission: mail-submission

Not quite. There are 2 distinct requests:

* The Ajax request made from the browser to the server and its response. This is what you see in Firebug, and is "internal" to Orbeon Forms.
* The submission done from the server to your service. That is the submission that contains the data you are interested it. If you get a nightly build and set the XFormsModelSubmission to log at the debug level (see: http://wiki.orbeon.com/forms/doc/developer-guide/xforms-logging), you can see what is sent to your service, and what comes back. This is what we are interested in.

So in addition to testing this with nightly build, I recommend you add XFormsModelSubmission in debug mode to you log4j.xml and see what is sent and received by the service. Also add a debug on the output of the pipeline to see what is returned by the pipeline.

Can you maybe point me to an example of what I want; a submit that 'goes' to
java and returns the result? Like 'success' or 'failure'... There should be
one or two I think...?

Using the Java processor there is generic-init-database.xpl in the examples, but it doesn't return any data.

I also asked you this question:
- trying to call some orbeon functionallity in my own java code to turn the
complete node into a stripped one that only has the relevant nodes.. You do
this somewhere in orbeon code, don't you? Can I call this code? Since I have
the context available?
Do you know an answer to this one?

What do you mean by stripped node? I assume you have a DOM in Java, from which you want to remove node; which one?

Back to my problem with popup blocking:
I' m always working with FF3 and IE8 and everything works fine there, but if
I use IE6 en IE7, popup blocking is in the way and if I then choose to allow
popups, the pdf is NOT downloaded AND the form is refreshed and all data id
gone...
My quess my first question is; doesn't ring this a bell somewhere with you?
Am I the only one with this problem as you know?

You're not. And the only reliable way I know to do this, at the HTML level, is to have in the page a simple link Download PDF. If you have the file you want to serve in a node (base64 or URI to temporary file), you can use an <xforms:output ref="file1" appearance="xxforms:download">. You'll find an example of this in output-download.xhtml, and more documentation on:
