So I have a clickable dataTable that's based on a join of two tables. There is a submit button for each row of the dataTable. I can't use the @DataModelSelection annotation (commented below) b/c the List does not consist of only one Entity class, it's based on two. How can I identify which row needs to be updated and get all the necessary data for the 2nd table to be persisted to DB? 1st table is read-only. sounds like @DataModelSelection is out of the question here (Java generics does not allow me to specify more than one type per Collection). any help much appreciated, otherwise I will resort to Seam remoting/ajax call onclick of submit button per row... code snippet from SFSB: @DataModel | private List myAuditList; | | @DataModelSelection | //private TblSecurityAuditWorking tblSecurityAuditWorking; | | @Factory("myAuditList") | public void find() | { | | log.info("in find(): user.getUserId() = " + user.getUserId()); | log.info("in find(): user.getBillingId() = " + user.getBillingId()); | | int employeeId; | | if (!networkId.equals("")) { //user entered a networkId from UI to run for another person, so get new guy's billingId | | List myList = em.createQuery("from User u where u.networkId = :networkId").setParameter("networkId", networkId).getResultList(); | User newUser = (User)myList.get(0); | | employeeId = newUser.getEmployeeId().intValue(); | | myAuditList = em.createQuery("SELECT gem, tsaw "+ | "FROM TblSecurityAuditWorking tsaw, "+ | "GlobalEmployeeMaster gem "+ | "WHERE tsaw.id.siteId = gem.id.siteId "+ | "AND tsaw.id.employeeNumber = gem.id.employeeNumber "+ | "AND tsaw.reportToId = :employeeId") | .setParameter("employeeId", employeeId) | .getResultList(); | } | } View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4099513#...
