Using the xml of a xforms:submission as model

> Hi!
>
> I’m trying to load a page with a certain view and a parametrized xml
> document as a page data model (which may be reloaded later on).
>
> My initial and naive idea was to load the page with an (optional) parameter
> that changes the element „/ticket/parameter/foo“ of the default-submission
> ticket „ticket.xml“.
>
> The modified default submission shall be submitted (it is selected as input
> instance oft he XPL pipeline „getData.xpl“, is in feature transformed by an
> XSL and is submitted to an other service which in turn sends the proper
> response as a XML document).
>
> The returned XML document is inserted in the xforms-form-description
> „view.xsl“ as the content of an instance (by an xsl:copy-of operation).
>
> So i came up with something like that (all sources below):
>
> Called URL „http://localhost/orbeon/test09/?foo=234567“
>
>         <page path-info="/test09/" model="test09/getData.xpl"
> view="test09/view.xsl" default-submission="test09/ticket.xml">
>                 <setvalue ref="/ ticket/parameter/foo" parameter="foo"/>
>         </page>
>
> My idea of the chain is something like:
>
> URL-Request -> Orbeon-Page [
>
> extract GET-param of request -> alter „ticket.xml“ data by GET-param -> send
> altered XML instance „input“ by „getData.xpl“ [
>
> send XML instance „input“ by xforms:submission via post to
> „http://xmlservice.loc/backend/process-ticket/“ in the XPL pipeline
> „getData.xpl“ -> retrieve XML as „data“ instance
>
> ]
>
>                 -> build XForms form page [
>
>                         execute XSL page view [
>
> insert „data“ instance as copy
>
> ]
>
>                         ]
>
>                 ]
>
> This does not return the XForms form (but an empty page) and on the log I
> can see that there is most probably the XPL is processed as input for the
> submission or the submission return is overwritten by the form source code.
>
> How can I code what I want to do properly?
>
> If you can tell me an other option I’m happy as well. I might send the
> request as an auto submit after page load. I thaught abaout that (actually
> it’s the way we did it before) but I was not shure if this ist hat clever
> especially because the send XML data is very big (but of course it is not
> transfered to the client actually).
