JPQL: navigation through embedded class field does not work
-----------------------------------------------------------
Key: OPENJPA-461
URL: https://issues.apache.org/jira/browse/OPENJPA-461
Project: OpenJPA
Issue Type: Bug
Components: query
Affects Versions: 0.9.7
Environment: BEA WebLogic Server 10
Reporter: Ajay Aggarwal
Hi Ajay Aggarwal,
I think your query is correct and should work. According to the Java
Persistence query language BNF the expression following the keyword SET might
be a state_field and state_field includes navigation through an
embedded:
state_field ::= {embedded_class_state_field.}*simple_state_field
I propose you file a JIRA issue.
Regards Michael
