This example works fine in seam 2.0.0 GA.
Thanks in advance Kruno.

Ok, please file an issue in JIRA, and I will take a look for CR2.

Thanks!

[cpopetz]

I think this is only an issue for SMPCs that aren't named entityManager, and is due to changes for JBSEAM-1242 which replaced EntityConverterStore with EntityLoader and HibernateEntityLoader.  It used to be sufficient to put:

    <component name="org.jboss.seam.ui.EntityConverter">
        <property name="entityManager">#{yourEM}</property>
    </component>

in your components.xml to make the converter find the right EM.  Now entityManager lookup is delegated, and
EntityLoader in particular is hardcoded to always look for a component named entityManager.  I think that's probably incorrect, and so I've created JBSEAM-2863

As a workaround, if you put:

<factory name="entityManager" scope="stateless" auto-create="true" value="#{myEM}"/>

in your components.xml, it will give you the correct behavior.  Or, at least it did for me.

[kruno]

Thanks a lot workaround worked for me to.
I suppose  the problem lies in:

@Name("org.jboss.seam.ui.entityLoader")
@Install(precedence=BUILT_IN)
@Scope(STATELESS)
public class EntityLoader extends AbstractEntityLoader<EntityManager>
{
     
  ...

   @Override
   protected String getPersistenceContextName()
   {
      return "entityManager";
   }
...
