I have an app with Multiple Entity Managers, ie one for each repository. The main reason for this is so that the user can save/cancel save for each entity manager without affecting the others.

However, we now have the issue of duplicate entities being downloaded from the server and would like to avoid the extra round trips.

Any suggestions on this?

One option is this:

- Fetch data into EM1
- Import data from EM1 into EM2. Make changes or cancel, then either save from EM2 and merge back to EM1, or merge back to EM1 and save from there.
