Yes, you can do it if you write a jBPM Converter that knows how to persist the objects primary key to the jBPM database.
BTW, you don't need @Intercept(InterceptionType.NEVER) on an entity bean.
Other than writing a converter, is there any other way, or better approach than that? Or the converter is the way to go?
You can just keep the id of the object in the business process context.
Is there an example on this? In the documentation or among seam examples?
I´ve checked the dvd store example, that seems to be the closest to what I want, but it didn´t help much on this issue.
