When writing the following...

Dim customers As New Dal.CollectionClasses.CustomerCollection
customers .GetMulti(Nothing)
Dim id As System.Guid = customers(x).ObjectID

Why is the id, for every valid unsigned integer x, always an empty Guid? Am I missing something here?

Information: Selfservicing General 2005

Note: I've checked that the customers are indeed filled and that customers(x) gives valid entity objects

Do you have a field ObjectID which is a GUID? (and you got somewarnings during compilation?)

I haven't got any warning during compilation. I didn't explicitly define a field named ObjectID, as I assumed this is defined within every entity (by the EntityBase class). Or is ObjectID something you must maintain yourself?

Could you please give us the information requested in the guidelines? We can't help you further without this information: http://www.llblgen.com/tinyforum/Messages.aspx?ThreadID=7722

The ObjectID is created when the entity is instantiated. Please be sure to use the latest vb.net templates for v2.0 if you're using v2.0. A bug was found when initializing entities in a particular case, I'm not sure if you run into this, but it could be.
