[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3562) update() should consult the dirty flag on the persistence context
update() should consult the dirty flag on the persistence context
-----------------------------------------------------------------
Key: JBSEAM-3562
URL: https://jira.jboss.org/jira/browse/JBSEAM-3562
Project: Seam
Issue Type: Feature Request
Components: Framework
Affects Versions: 2.1.0.CR1
Reporter: Dan Allen
Assignee: Dan Allen
Priority: Minor
Fix For: 2.1.0.GA
When update() is called on a Home instance, only attempt to flush, register the status
message, and raise the transaction success event if the persistence context was dirty. Of
course, this only is effective if Hibernate is the persistence provider.
@Transactional
public String update()
{
joinTransaction();
// For a non-Hibernate JPA provider, this always returns true
if (PersistenceProvider.instance().isDirty(getEntityManager()))
{
getEntityManager().flush();
updatedMessage();
raiseAfterTransactionSuccessEvent();
return "updated";
}
return "unchanged";
}
