Passing Parameters ins JSF 2.0

Question

Hi,

till now i used in JSF 1.2 commandLinks and the setPropertyActionListener to pass for e.g. the selectedItem of a DataTable.

<h:commandLink action="#{Result.show}" value="#{foo.name}">
<f:setPropertyActionListener value="#{foo}" target="#{Result.selectedFoo}"/>
</h:commandLink>

In an example JSF 2.0 and JPA i have seen a solution, where the selected Item is passed as parameter to a function. But if i try to execute this function on a Glassfish 2.1 Server i'am getting an Exception.

<h:commandLink action="#{Result.showFoo(foo)}" value="#{foo.name}">

      </h:commandLink>

javax.faces.view.facelets.TagAttributeException: javax.el.ELException: Error Parsing: javax.servlet.ServletException:

I'm only using simple ManagedBeans, no EJB.

Thanks.

The Unified Expression Language (all that #{}/${} stuff) is maintained as part of the JSP spec. You probably need a newer version of the JSP API. I see that Glassfish v3 includes EL 2.2. I believe that spec includes the functionality you want.
