I read the section on Fields on Related Fields: http://www.llblgen.com/documentation/3.1/Designer/Functionality%20Reference/EntityEditor_FieldsTab.htm

However, I'm not completely certain on how to use them. I'd assume that these fields just get populated when you do a fetch entity, these fields automatically are fetched from the related entity.

I added some fields, but they aren't getting filled.

How do I do that? Am I missing something, or am I misunderstanding the usage of this feature?

Fields on related fields, don't get populated when fetching the main entity. They will be populated when the related entity get fetched.

What they are used for? This gives you the ability to create a property on an entity, that get's it value from another property/field on a related entity, might be useful when databinding, if you don't want to access related entities at databinding.

So don't use them unless there is a need for them.

Ah! I think I get it. So you still have to do the prefetch... and the field is just a property that accesses the field in the child entity?

If so, that makes sense and yes, it would work well in my case of data binding for display purposes.

Thanks.

Exactly. You need to populate the related entity with a prefetchPath when you fetch the main entity.
