Neat dms connections reverse 006

Validates that the container property used in reverse connection is the direct relations.

What it does

Checks that the container property (mapped from view's direct connection property) has type DirectNodeRelation.

Why is this bad?

Container properties backing connection view properties must be DirectNodeRelation type. Other types cannot represent connections in the underlying storage.

Example

If WindTurbine.windFarm maps to container property with type Text instead of DirectNodeRelation, the connection cannot be stored correctly.
