In updating an object, while in a transaction (I am using it with
spring.net and using spring's declarative transaction management), I
need to retrieve the persistent copy of the object from the database
and then compare it with the object that is passed in to my method.
After performing my check, I try to update the original object that
was passed in and get the error that another object is already
associated with this id in cache.
UpdateMyObject(object o1)
{
1. retrieve o2.
2. compare o2 with o1.
3. try to save o1.
}
I assume what is happening is that when o2 is retrieved, it gets in
the session cache. So when I try to update o1 in step 3, I get this
error.
I tried to evict o2 after step 2 by calling Evict on the current
session, but that did not make any difference. Can anyone please
help.
Thanks in advance.
