koen handekyn commented on JBSEAM-3557:
---------------------------------------
i discoverred the rationale behind this
Any <s:link> or <s:button> transparently includes the request parameter. The value of the parameter is determined by evaluating the value binding during the render phase (when the <s:link> is rendered).
HOWEVER
i would still propose a totally "stateless" s:link equivalent than, i defined one as follows using facelets ( as a temp patch)
<h:outputLink id="#{id}" value="#{facesContext.externalContext.requestContextPath}#{fn:replace(view,'xhtml','seam')}">
<h:outputText value="#{value}"/>
</h:outputLink>

> Key: JBSEAM-3557
> URL: https://jira.jboss.org/jira/browse/JBSEAM-3557
> Project: Seam
> Issue Type: Bug
> Affects Versions: 2.0.2.GA
> Environment: independent
> Reporter: koen handekyn
> Priority: Minor
>
> let's say you have a page form1.xhtml with a form1.page.xml that contains a param instruction that sets a page param on a seam object #{someseamobject.someproperty}.
> let's say you have a main page with an s:link to form1.xhtml.
> when opening the main page that does NOT have ANY reference to "someseamobejct" however, seam instantiates "someseamobject', seamingly because there is an s:link to a page that has a param instruction on "someseamobject'.
> most of the times this just wastes resources or at best instantiates components to early.
> FIX: DO NOT USE S:LINK but fall back to h:outputLink (which has other drawbacks)
