[jboss-user] [JBoss Seam] - how to use DataModelSelectionIndex correctly ?(newbie questi

Hi, Trying to use the DataModelSelectionIndex to pick up particular row of data and use it to do another query from other Action.java. I am not sure if I have done it right or not. I just can't get the data from the database. this is what I have done. Have been stuck on it for a while. Appreciate any help. | @DataModel | private List<Customer > customers; | @DataModelSelectionIndex | private int customerIndex; | | @Out(required=false) | private Customer customer; | | @Factory("customers") | public void findCustomers() | { | customers = em.createQuery("select c from customer c").getResultList(); | } | | public String selectcustomer() | { | setcustomer(); | return("selected"); | } | | public void setcustomer() | { | customer= customers.get(customerIndex); | } | And I inject customer on the other Action.java and use it to query for related data. but it doesn't work. Am I doing it wrong? Here's the code for second Action.java | @In | private Customer customer; | | @DataModel | private List<Result> results; | | public void getResult() | { | | results = em.createQuery("select r from Result r where r.subscription_id = :SID") | .setParameter("SID", patient.getId()) | .getResultList(); | | } | build and deploy successfully but just not returning anything from getResult, a blank page. I have no idea why. Regards, Andy View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4078333#...
