[jboss-user] [JBoss Seam] - Parameter in EL in a POJO env

[esoares]

I have faced a problem when passing parameters to a method using EL in a POJO environment (non-EJB and non-hibernate). I have setup the SeamFaceletViewHandler in faces-config.xml, as well.

Here is the xhtml sample :

<h:dataTable value="#{fruitList}" var="fr">

    <h:column>
       <f:facet name="header">
         <f:verbatim>Description</f:verbatim>
       </f:facet>
		      
       (1) <s:link value="#{fr.name}" action="#{fruitBasket.select(fr.id)}"/>
       
       (2) <s:link value="#{fr.name}" action="#{fruitBasket.select(fr)}"/>
     </h:column>
</h:dataTable>

In case (1) the fr.id is not interpreted by EL and stays as "fr.is" in the rendered HTML!

In case (2) I do not receive any error, but the object Fruit related to variable fr, is not passed.

 Looking at Hibernate sample I got the alternative using @DataModelSelectionIndex, but I would like to understand why the code above does not work since this simple approach may not be suitable in complex interations when I need to pass more than the "index".

I am evaluating Seam to be used in a project.
