PropVal has a 1-M association with PropValHistory; PropVal has an IList<PropValHistory> History property. PropValHistory collection is specified as lazy fetch in the class mapping for PropVal. What should I see in the debugger when I do a get-by-id for PropVal? I currently see the nHib wrapper collection object filled with PropValHistory objects; does the debugger's access of the History collection result in the wrapper collection object being accessed and the select being run?

Thx,
Bill

Yes, examining proxies in the debugger will cause them to be initialized. If it makes a difference to what you are debugging, don't have the Locals or Autos windows visible, and be careful about what objects you examine.

In the Immediate window or the Watch window, you can do

first if you're not sure whether the entity/collection is initialized or not, and wait until it is initialized before examining it any further if that matters to what you're trying to debug.
