Hi,

I've read the doc and still can't get this Seam feature to work. Essentially I have something simple but I keep getting this:

My components.xml is like this

<core:init debug="true" jndi-pattern="mytime/#{ejbName}/local" />
<persistence:managed-persistence-context name="entityManager" auto-create="true"
 persistence-unit-jndi-name="java:/mytimeEntityManagerFactory" />

My Page is like this:

<h:selectOneMenu value="#{tag.group}">
 <s:selectItems value="#{items.groups}" var="item" label="#{item.name}" />
 <s:convertEntity />
</h:selectOneMenu>

where tag is an entity and item.groups is a list of name value pairs

Any help is appreciated

Thanks

Troy

Can we see the session bean that #{items} refer to?

Here it is :)

@Name("items")
@Scope(ScopeType.CONVERSATION)
public class Items {

 @Logger Log log;
 @In EntityManager entityManager;

 private List<Group> groups;

 @Create
 public void init() {
 log.info("init()");
 groups = entityManager.createQuery("select g from Group g").getResultList();
 }

 public List<Group> getGroups() {
 return groups;
 }

 public void setGroups(List<Group> groups) {
 this.groups = groups;
 }
}

What results will you get when you put a @Stateful on that bean. If that didn't work, I am wondering if there is something wrong in your components.xml and the @In EntityManager is not getting set right.

Lets us know,
