12:59 p.m.
First let me explain what I trying to do.
I'm using Seam 1.2 with Ajax4JSF and I'm trying to change the value of a
selectOneMenu by using ajax on a selectOneRadio.
The problem is that the value sent back never changes even as the value on the page is
changed. Do you have to submit the page to get the value to change?
Here's the relevant code:
| <f:view xmlns="http://www.w3.org/1999/xhtml"
| xmlns:s="http://jboss.com/products/seam/taglib"
| xmlns:ui="http://java.sun.com/jsf/facelets"

| " select shipyard from Shipyard shipyard " +
| " where shipyard.shipyardStatus.statusId=:status")
| .setParameter("status", getStatusId()).getResultList();
|
| return shipyards;
| }
|
| }

I've tried various ways of using the @In annotation to no avail.
Any help would be appreciated.
