Hai Alex,

thanks again. This indeed seems to solve the loosing of data in the form thing. And if you say this is the way, then I'll do it this way. Thanks. Now I only have to figure out how my customers handle popup blocking..

But.... here comes the next thing to figure out:
Now I also want to add a link to mail the PDF (as an attachment). With that functionallity I want the form to stay the same, meaning on the same case of a switch for instance, and I want a message on the screen with the result of the mail process....

I can get this behaviour with:

<xforms:setvalue value = "xxforms:call-xpl('oxf:/apps/e-formulieren/forms/xpl/mail.xpl', 'data', instance('form-instance')/formcontent, 'data')" ref = "instance('result-instance')/success"/>

But, this will submit the complete node 'instance('form-instance')/formcontent' instead of only the relevant parts in this tree (specified in the bindings). In other words, I loose the orbeon submit functionallity.

So, how to solve this?
I thought of:
- 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?
- Using <xforms:submission anyway with replace="instance" and instance="result"...

I guess (hope) the latter is possible, but I get the message:
"XFormsServer  - XForms - submission - instance replacement did not take place upon successful response because no body was provided. Submission: mail-submission"

these are parts from my form:
            <xforms:instance id = "result-instance">
                <root>
                    <result/>
                    <failure/>
                    <success/>
                </root>
            </xforms:instance>
and
            <xforms:submission
                id = "mail-submission"
                ref = "instance('form-instance')/formcontent"
                xxforms:show-progress = "false"
                method = "post"
                action = "/e-formulieren/mail"
replace="instance"
instance="result-instance">
            </xforms:submission>

and in code I return a Document of form
<root>
                    <result/>
</root>

Can you help (again)?
