SeamExtendedManagedPersistence: when does a commit occur?
Hello,
i do need to understand SeamExtendedManagedPersistence a little better. hope you can help me.
The stacktrace below is correct, when the commit of the transaction is correct. But why does the commit occur?
Here a plot of my situation:
A new object should be assembled in a long running conversation.
- start conversation
. assign objects from database
- edit further properties
- save object and end conversation.
The stacktrace occurs when i execute this code (setting a bidirectional association):
getProtocol().addMarker(primer); primer.setProtocol(getProtocol());
where protocol is the Object to create (not persistent) and primer is a persistent object fetched from database in the current long running conversation.
It is true, that protocol.name is not set since this and other properties will be filled in by the user.
My question: I like to understand why the commit occurs.
IMHO, a commit should only occur when my conversation ends.
Is there something that i can do to prevent the commit?
I am running hibernate in the jboss microcontainer on tomcat.
Ciao,
Carsten Hoehne
