    Outjected variable as parameter for enhanced EL

      Hi,

      how can I get an outjected object as a call parameter for an action method in a Facelets XHTML page?

      In DataTable its easy by using

       <h:dataTable id="customerlist"
 value="#{customerList}"
 var="customer">
 ...
 <h:commandLink value="#{customer.name}"
 action="#{ChooseCustomer.showDetails(customer)}"/>
...


      But if I haven't got a data table, i've no idea how to do that with enhanced EL. Nested EL expressions obviously doesn't work (choosenCustomer is outjected here by @Out and present if I check it with #{choosenCustomer.name}): 

      <h:commandLink id="back-customerdetails"
 value="Back to details"
 action="#{ChooseCustomer.showDetails(#{choosenCustomer})}"/>


      And that one doesn't work, too - as expected: 

      <h:commandLink id="back-customerdetails"
 value="Back to details"
 action="#{ChooseCustomer.showDetails(choosenCustomer)}"/>


      Is there any solution with enhanced EL or am I doomed to use page parameters?

          This is the one that should work. What scope do you outject the chosenCustomer to?

            By now, I solved the problem with page id.

            What scope do you outject the chosenCustomer to?


            I did outject it at standard scope (only with @Out). The page with the commandLink is generated from an @End annotated action method. Oddly enough 

             <s:link id="back-customerdetails"
 value="Back to details"
 action="#{ChooseCustomer.showDetails(null)}">
 <f:param name="custno" value="#{choosenCustomer.customerNo}"/>
 </s:link>


            does work now, but 

            <h:commandLink id="back-customerdetails"
 value="Back to details"
 action="#{ChooseCustomer.showDetails(choosenCustomer)}"/>

            did not.

            And don't nail me down to it, but I'm quite sure that I used commandLink inside form tags.
