Use Entity Manager action generates field for EntityManagerFactory
and generates a sample method showing how to use the factory. It doesn't
generate a new field if the class already contains a field for
EntityManagerFactory - that's good, but it generates a field for a factory
even if the class already contains a field for the EntityManager itself
(which is common in J2SE application). Please, don't generate a field
for a factory in that case and make sure that the generated sample method
uses the existing entity manager.
I've update the action in the merged_model branch to use an existing
EntityManager if there is one. I'll leave this issue open till the
branch has been merged to trunk.
Closing as the branch has been merged to trunk now.
