Updates to entities via Lifecycle callback methods
---------------------------------------------------
Key: OPENJPA-732
URL: https://issues.apache.org/jira/browse/OPENJPA-732
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 1.2.1, 1.3.0
Reporter: Kevin Sutter
http://n2.nabble.com/Updates-to-entities-via-Lifecycle-callback-methods-td1110631.html
In a nutshell, if we are to allow the updating of the entities passed into the
Lifecycle callback methods, then we have a couple of problems (given the
scenario of updating the entity passed into the @PreUpdate method):
o The designated @Version field is getting updated more often than desired
causing the transaction to rollback.
o The @PostUpdate method is getting invoked more than once.
I will post a testcase shortly. If and when we decide to fix this, this simple
testcase will need to be expanded to include the updating of entities in other
scenarios as well.
I am also getting verification from the JPA Expert Group as to whether these
entities are supposed to be updatable or not. As one of the dev postings
indicated, our OpenJPA documentation indicates that they are updatable. But,
the JPA spec itself is not clear on this capability. Other vendors, such as
Hibernate, allow for this.
