Re: [eclipselink-users] EclipseLinkM6 doesn't properly detect added/changed details
|
Thanks for your assistance. Below I'll give you an idea of the queries executed.
Immediately after the import has been completed, and without Tomcat6 restart, I see the following query:
[EPS Finer]: 2008.05.07 14:48:33.001--ServerSession(1170294209)--Thread(Thread[http-8080-1,5,main])--client acquired
[EPS Finest]: 2008.05.07 14:48:33.003--UnitOfWork(1138967523)--Thread(Thread[http-8080-1,5,main])--Execute query ReadAllQuery(com.acme.lighting.guidecontrol.model.IndustrialFamily)
[EPS Finest]: 2008.05.07 14:48:33.003--ServerSession(1170294209)--Thread(Thread[http-8080-1,5,main])--reconnecting to external connection pool

AND (t0.family_id = t1.ID))
bind => [21811]
[EPS Finest]: 2008.05.07 14:48:33.009--UnitOfWork(1138967523)--Thread(Thread[http-8080-1,5,main])--Register the existing object com.acme.lighting.guidecontrol.model.IndustrialFamily@22702270
No detail records are queried/displayed.
But now when I restart tomcat6 I see:

Obviously there is some difference, although I cannot explain it - because I see the exact same query being fired.
Any idea?
