Xie Min,
This is a great find, very close to what I'm talking about. However,
in the following line:
<to-view-id>/view.jsp?objectId=#{view.objectId}</to-view-id>
what object does 'view' in the EL expression reference? Is this an
implicit object, or one defined in a configuration somewhere? If it is
implicit, how do I set it's properties from a backing bean?
Thanks a lot,
benjamin

threr are some suggestion on url parameters passing:
Dynamic Url parameters passing: This allows passing parameters between pages
even when using redirection method. For exmaple, in order to navigate from a
pages name: view.jsp to a page named: edit.jsp, with the parameter:
objectId, the following thing can be done in navigation rule code:
<navigation-rule>
<from-view-id>/view.jsp</from-view-id>
<navigation-case>
<from-outcome>edit</from-outcome>
<to-view-id>/view.jsp?objectId=#{view.objectId}</to-view-id>
<redirect />
</navigation-case>
</navigation-rule>
