Be careful when copying the Find and Exist methods to other tables as a template. As they are static, the methods can technically be on any class or table - that is, check the return type. This can cause some confusion when they behave strangely. As EDTs can be used interchangeably, we won't get a type error unless the base type of the EDT is different. This means that you could pass a variable of type ConWHSVehicleGroupId to InventItemGroup::Find(), and it would simply return a record (or empty buffer) of type InventItemGroup. So, if we copied the Find method from InventItemGroup, to our table the following scenarios are possible:

ConWHSVehicleGroup   group;   
group =   ConWHSVehicleGroup::Find(<val>);   

ConWHSVehicleGroup::Find(<val>).Description;
