I'm using self-servicing:

I've got two entities Employee and Photo There is a one-to-many relationship so one employee can have many photo's.

Let's say I have this:

Dim x As Integer = frmSelectedEmployee.SelectedValue
Dim emp As EmployeeEntity(X)
Dim photos As PhotoCollection = emp.Photo

The telephone entity has a field named PhotoType which I want to filter on so that the photo collection will contain only those photo entities whose PhotoType = 3, how can I do that?

If I use photos.GetMulti(expression) at this point will that return a new collection or "trim" the collection I currently have instantiated?

That's added in v2 using filtering on entitycollections, using entityviews. If you want to use it in v1.0, you've to manually traverse the collection and copy over the entities to a different collection.

Thank you. BTW v2 looks awesome, i'm testing it out now.
