[jboss-user] [JBoss Seam] - Re: Can EntityConverter handle different EntityManagers?

[wiberto]

If I don't have a component called "entityManager" I get a n NPE:

Here's my piece of the components.xml with the real names I'm using:


  | <persistence:managed-persistence-context name="numinsEntityManager"
  |                                       auto-create="true"
  |                        persistence-unit-jndi-name="java:/numinsPersistenceUnit" />
  | 
  | <component name="org.jboss.seam.ui.entityConverter">
  |   <property name="entityManager">#{numinsEntityManager}</property>
  | </component>
