I have some functionality in my application that I want to off load to seperate parallel tasks. The application is a client application with a single Entity Manager and most of the DevForce uses synchronous requests. The functionality I want to do in parallel tasks uses both scalar queries and property navigation of entities. I know how to convert the scalar queries but how do I handle the property navigation to avoid an exception that Entity Manager can only run on a single thread?

Hi Ron,

You'd use http://drc.ideablade.com/xwiki/bin/view/Documentation/parallel-async-coroutines - Parallel Async Coroutines in this case.

Can you provide more information on exactly what you are doing that is causing the exception stated? (please provide snippet and/or solution sample)

Regards,
   Silvio.

My post was more of a question for information than an actual issue. I did not know if I needed to avoid property navigation or make sure I use "Includes"... that kind of thing. I will alsp look at using coroutines.  Thanks...
