Question

I have a template where i need to set a ui:param:

<ui:param name="pageCononical" value="#{somevalue}"/>

The value=”#{somevalue} needs to be this s:link:

<s:link id="canonical" view="/rewriteSearchLink/resultsPage.xhtml" propagation="none">
   <f:param name="searchString" value="#{currentSearch.searchString}"/>
   <f:param name="placeString" value="#{currentSearch.placeString}"/>
   <f:param name="currentPage" value="#{currentSearch.currentPage}"/>
</s:link>

How do I do it?

Answer 1

<ui:param/> is intended for passing strings and similarly simple values. The functionality you’re after is provided by <ui:insert/> and <ui:define/>.

In your template you need to indicate an insertion point via <ui:insert/>:

<ui:insert name="pagecanonical" />

In your page, include the template via <ui:decorate/> and redefine the pagecanonical placeholder with your link:

<ui:decorate template="mytemplate.xhtml">
  <ui:define name="pagecanonical">
    <s:link id="canonical" view="/rewriteSearchLink/resultsPage.xhtml" propagation="none">
      <f:param name="searchString" value="#{currentSearch.searchString}"/>
      <f:param name="placeString" value="#{currentSearch.placeString}"/>
      <f:param name="currentPage" value="#{currentSearch.currentPage}"/>
    </s:link>
  </ui:define>
</ui:decorate>
