submission with replace not working

Two model instances:

<f:instance id="accesscontrol-instance">
   <paswoord/>
</f:instance>

<f:instance id="message-instance">
   <message/>
</f:instance>

One submission of one instance ('accesscontrol-instance') to replace the other one (message-instance).

<f:submission id="accesscontrol-submission"   ref="instance('accesscontrol-instance')"
action="/spil-edit/access-control"
method="post"
replace="instance"
instance="message-instance">

The action is mapped to access-control.xpl
<page path-info="/spil-edit/access-control">
   <action action="services/access-control.xpl"/>
</page>

which does nothing more than:

 <p:param name="instance" type="output"/>

 <p:processor name="oxf:identity">
     <p:input name="data">
         <message>true</message>  
     </p:input>
     <p:output name="data" ref="instance"/>
 </p:processor>


But message-instance doesn't seem to get updated.

What am I missing?

Paul,
        The action output isn't copied into the data reply to the page. You
should be using

<page path-info="/blah" model="path/to.xpl"/>

The missing piece was adding
 <p:processor name="oxf:xml-serializer">
        <p:input name="data" href="#message"/>
        <p:input name="config">
            <config>
                <content-type>text/xml</content-type>
            </config>
        </p:input>
    </p:processor>
in the XPL file.

However still have following questions and issues:
a) I'm not really understanding when this xml-serialising processor is needed.

b) I can access now

<f:instance id="message-instance">
<message>true</message> <-- generated by xpl
</f:instance>


with

<f:group ref="instance('message-instance')">
    <h:p>Message <f:output ref="/message"/>
    </h:p>
</f:group>

However if I want to do something analogue in following context

<f:action ev:event="xforms-submit-done">                  
  <f:action if="instance('message-instance')/message = 'true'">
      <f:toggle case="case1"/>
  </f:action>

I do not seem to get access to the instance.

Still confused.

The page model does not automatically take care of serialization. If
you want to send a result to the client directly from a page model,
then you need to use a serializer as you have done above.

A page view on the other hand (hence the name "view") will
automatically serialize data produced on its "data" output through the
epilogue pipeline.

(Note that strictly speaking, oxf:xml-serializer is deprecated and you
are meant to use instead oxf:xml-converter + oxf:http-serializer.)

See Alex's recent blog post:

 
http://www.orbeon.com/blog/2006/11/05/xpath-hack-tip-trick-doc-document-node/

instance('message-instance') returns a document element, not a
document node. So just write:

   if="instance('message-instance') = 'true'"
