Same problem with the CRUD Customer Application if built on scratch fro the Netbeans Tutorial.
It seems impossible to view the persistence.xml.
The problem has born in the moment I did Clean and Build over the Netbeans Platform Application.
Before I was making changes on single modules and the Persistence Library did not any problem.
Everything seemed to function very well until tah moment of Clean and Build over the Netbeans Platform Application.
This was the reason I tried to built from the tutorial but after buiding the viewer component I got the same problem.
Thanks.

Also changed the database driver PostgreSQL with the version useful in the Services tab to make the connection.
but with no result. The topcomponent can't be instantiated because the EntityManager do not find
the persistence library unit, it seems. I repeated the tutorial http://platform.netbeans.org/tutorials/nbm-crud.html#creating-entity

Comment 4 Sergey Petrov 2014-07-14 14:17:22 UTC

when I should try to clean/build to reproduce the issue?

This old bug may not be relevant anymore. If you can still reproduce it in 8.2 development builds please reopen this issue.

Thanks for your cooperation,
