Chris Rudd commented on JBSEAM-1942:

It would be nice if output had the ability to set into a VB instead of just a context variable name

 <output var="#{Editor.id}" value="#{Picker.id}"/>

>             Project: JBoss Seam
>          Issue Type: Feature Request
>          Components: Core
>    Affects Versions: 2.0.0.CR1
>            Reporter: Chris Rudd
>            Priority: Minor
> It would be nice if you could specify that a page parameter was not to be included in generated url.
> There are circumstances where I only want the "inbound" functionaliry (setting a request param into a VB) and not the "outbound" functionality (automatically appending the parameter to an generated urls for the view).
> The <in> functionality may be a better candadite, as its controlling inbound parameters, but currently it cannot be used to store a parameter value into a VB ( you can only put a  component retrieved from the sepcified context into a VB).
> Ie.
> If there is an id parameter specified on the url I want to place it into #{Editor.id}. However I do not want an id parameter automatically added for all links to the view.
> Currently I "workarond" this by adding
> <action execute="#{Editor.setId( param.id )}" if=#{param.id!=null}"/>
> But it seems like thats abusing the action node
