[jboss-user] [JBoss Seam] - Re: SelectOneMenu and OneToMany Seam 2.0 setup

You really should take a look at some of the examples and read the reference. I found it *extremely* useful to use SeamGen to start with. Gives you something that works right away.

For starters, you need something to provide a list of zipcodes. In your page you have:<s:selectItems value="#{zipCodes.resultList}" var="zip" label="#{zip.zipcodeNumber}" />

But zipCodes is an entity and has no method called getResultList() or resultList(). You have 2 easy options:

1. Add an entityQuery to your components.xml<framework:entity-query name="zipCodeList" 
  |                         ejbql="select z from ZipCodes z"/>
2. Create a Bean that builds the list:

  | @Name("zipCodeList")
  | public class ZipCodeList() {
  | @In(create=true)
  | EntityManager entityManager; //actually you need to add this to your components.xml as well!
  | 
  | public List<ZipCodes> getResultList() {
  | 	return entityManager.createQuery("select z from ZipCodes z").getResultList();
  | }
  | }
And then your page should have:
<s:selectItems value="#{zipCodeList.resultList}" var="zip" label="#{zip.zipcodeNumber}" />

Don't forget to add an entityManager to your components.xml:
<persistence:managed-persistence-context name="entityManager"
  |                                      auto-create="true"
  |                       persistence-unit-jndi-name="java:/OracleDS"/>

Have a play with that. There are a few other things you need to fix up as well but you should find them.

Cheers,

Damian.
