Hello,
I have a table in my database which stores our user data. The first field is
the username which is primary key. I can change the username in the database
without any problem. The primary key is never referenced as foreign key of
an other table. But when I change the username of a persisted object (user)
in my application and merge the new user with his new username, I get this
message:
javax.servlet.ServletException: javax.el.ELException:
<openjpa-2.2.0-r422266:1244990 nonfatal user error>
org.apache.openjpa.persistence.InvalidStateException: Attempt to change a
primary key field of an instance that already has a final object id. Only
new, unflushed instances whose id you have not retrieved can have their
primary keys changed.
FailedObject: jpa.RolloutUser-TEST
javax.faces.webapp.FacesServlet.service(FacesServlet.java:229)
org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:357)
I don't understand what this means. Does it mean, that it isn't even
possible changing the value of an primary key field with openJPA? Something
like a security feature?
The only thing I could do imho is deleting the user and create a new one
with the new username. But this is not very smart.
Do you have any suggestion?
Thanks in advance?
