NPE with component's entity-query

[trouby]

Hey,

With Seam ver 1.2 I used <framework:entity-query> a lot and it worked perfectly,


After migrating to Seam v2, I get a NPE exception,

I have a persistence managed context declared in components.xml as:

<core:managed-persistence-context name="entityManager" auto-create="true" persistence-unit-jndi-name="java:comp/env/edm_acc_em"/>

where in web.xml I have a 'persistence-unit-ref' reference,



Please note that I am using Glassfish V2 as an Appserver.


Following is a part of the NPE stuck trace:

Caused by: java.lang.NullPointerException

Thanks,

Try

<persistence:managed-persistence-context name="entityManager" auto-create="true" persistence-unit-jndi-name="java:comp/env/edm_acc_em"/>

(read the migration guide)

ye,

I just figured that out before few minutes,

core:managed-persistence-context doesn't through any exceptions, so it wasn't so obvious,


thanks.
