Sharing an Entity Between JSP's

[johnurban]

I have a jsf page that renders a table of data(DataModel). I can select a record by clicking on an edit link and do something logical inside a supporting SFSB, to that record.

Now I want to click on that record an show a new JSF with detailed data from that record. Is the trick that I need to use:

@Out in the supporting SFSB of the selectedObject, such that when the new JSF get rendered, the <h:outputText value="#{selectedObject.name}"/> is populated on the screen?

I should have posted the code:

JSF with the call that needs to get me to the other screen:

 <h:column>
 <f:facet name="header">
 <h:outputText value="Print"/>
 </f:facet>
 <h:commandLink value="print" action="#{personFinder.print}">
 <f:param name="id" value="#{id}"/>
 </h:commandLink>
 </h:column>

When I click on Print, I can see that I get the System.out in the server.log file:

00:12:42,820 INFO [STDOUT] inside print..:531

Here is the code for personFinder.print:

...
 @DataModelSelection
 @Out(required=false)
 private Person selectedPerson;
...
 @LoggedIn
 public String print() {
 System.out.println("inside print..:"+selectedPerson.getId());
 return "/uPrintLabel.jsp";
 }

It does indeed get to my uPrintLabel.jsp. But my firstName and lastName don't have anything in them:

<h:form>

 <table>
 <tr>
 <td><h:outputText value="#{selectedPerson.firstName}"/></td>
 </tr>
 <tr>
 <td><h:outputText value="#{selectedPerson.lastName}"/></td>
 </tr>
 </table>

</h:form>

This page contains nothing, even though selectedPerson has valid data inside of it. I need to display in this screen information about the selectedPerson.

In my app I've a similar use-case. I think I had the same problem, too. My solution was to integrate the "detailed code" like your getFirstName() method in the component which manages the list and the selected item.

I would prefer separated components, but I didn't find out how.

Are seperated components possible with seam? Old school way is the save the person object to the session or store it in a SFSB, then using the JSP's usebean, retrieve the data for display. How do you do this in Seam?
