Subject RE: Callback before items are persisted
Date Fri, 06 Dec 2013 16:34:23 GMT
Hi Jim,

could you provide some same sample code?
If your entity has values set before persist is called, then I can't imagine how they would
disappear when the PrePersist callback method is invoked.
Example 3.5.3 in the JPA 2.0 spec shows that you should be able to access persistent fields/properties
of your entity in the context of a PrePersist callback.

Subject: Callback before items are persisted


I want to modify a couple of persisted columns in an entity based on
data in other columns (basically caching some stuff from related entities).
I was under the impression that a lifecycle listener on PrePersist would
make this easy - but that is called from within the call to persist,
which is before any columns in the new entity have any values at all.

There doesn't seem to be any callback that is called just before an
object is written the database, is this true?
