Trying to migrate from jBoss4.0.5.GA+Seam1.2.1.GA to jBoss4.2.1.GA+Seam2.0.0.B1, after updating lots of code, app deploys properly, but when I try to acces initial page, an EntityHome complains and sends me to error page: In attribute requires non-null value: complexHome.entityManager at this arbitrary piece of code: @Name("complexHome") | public class ComplexHome extends GenericEntityHome<Complex> { | | @In EntityManager entityManager ; | | ... | I believe it fails here due to life cycle but has nothing to do with this (works nice and smooth with old jBoss + old seam). App has deployed properly, logs do not report any errors, components.xml looks like this (fragment): Components.xml (fragment) | | <core:managed-persistence-context name="entityManager" | auto-create="true" persistence-unit-jndi-name="java:/EntityManagerFactories/LaboraemPersistenceFactory" /> ... and EJTool's "JNDI Browser" (http://www.ejtools.org/) reports: java:/ | ConnectionFactory (org.jboss.mq.SpyConnectionFactory) | DefaultDS | DefaultJMSProvider (org.jboss.jms.jndi.JNDIProviderAdapter) | EntityManagerFactories | LaboraemPersistenceFactory (org.jboss.ejb3.entity.InjectedEntityManagerFactory) | EntityManagers | LaboraemPersistence (org.jboss.ejb3.entity.TransactionScopedEntityManager) | JmsXA (org.jboss.resource.adapter.jms.JmsConnectionFactoryImpl) | ... (more) ... ... so, the persistence unit has been deployed, I'm using the same injection I used for old seam, as seen in examples (even seam2 examples), so I believe things should work, yet, they don't :( Am I missing something ? Anybody ? Here's a bit of the stacktrace: org.jboss.seam.RequiredException: In attribute requires non-null value: complexHome.entityManager | at org.jboss.seam.Component.getValueToInject(Component.java:2042) | at org.jboss.seam.Component.injectAttributes(Component.java:1481) | at org.jboss.seam.Component.inject(Component.java:1302) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4071808#...
