Is it possible to use page parameters in Seam pageflow?

[wilczarz.wilczarz.gmail.com]

I have a page viewClient.xhtml defined in pages.xml as

<page view-id="/viewClient.xhtml" >  
    <param name="clientId" />
</page>

so clientId can be attached to a button via <f:param> and injected with @RequestParameter. I would like to enter this page after finishing pageflow, but I can't find a way to pass clientId with the final request. This is how the pageflow ends:

button
<s:button value="Finish" action="finish" /> triggers transition to final jpdl node:

<page view-id="/confirm.xhtml" name="confirm" >
    <transition name="finish" to="finishNode" />
</page>
<page view-id="/viewClient.xhtml" name="finishNode" >
    <end-conversation/>
</page>

Any help appreciated.

Just digging the topic out :) I'm sure this is a common problem for every pageflow user..
