okay so the mail-list won't let me send the test case as an attachment so
here are the files individually :
-------------
Attached is a simple test that shows both @PreUpdate and @PostUpdate are
called even when nothing is done at all.
- It requires maven2.
- I used jdk1.6 (but not required, modify the pom.xml for 1.5)
- I used 1.10-SNAPSHOT of the OpenJPA
- I used Mysql (not required but you will need to modify create tables.sql
and persistence.xml)
To run it do the following:
- run the create_tables.sql file
- configure the persistence.xml to your system
- run do an mvn test or run the junit test in eclipse
what I get is the following :
@PrePersist
@PreUpdate
@PostUpdate
@PreUpdate
@PostUpdate
@PreUpdate
@PostUpdate
@PreUpdate
@PostUpdate
Note that it did a Pre/Post update for every entityManager.find() I did
even though I didn't modify anything.

create_tables.sql

}
public void setId(int id)
{
this.id = id;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
@PrePersist
public void prePersist()
{
System.err.println("@PrePersist");
}
@PreUpdate
public void preUpdate()
{
System.err.println("@PreUpdate");
}
@PostUpdate
public void postUpdate()
{
System.err.println("@PostUpdate");
