just started using hibernate entity manager with spring injection on tomcat and I have some questions.
My application does some classic steps: spring creates entity manager and injects it in some another object where it can be used.
The next step is getting list of some objects representing some info in data base like this:
And after some modifications on myRecords I need to save them again.
Now it looks like myRecords list is detached. My question is: can I merge/update entire list at once or I have to iterate it and merge each list element individually.
All transactions managed by spring.
