Referencing collections bound to forms or grids
The framework provides a shorthand notation for referencing IDO collections that are bound to a form or a grid. The form's primary collection is referred to as "objects". The form's first secondary collection is referred to as "objects2"; the form's second secondary collection is referred to as "objects3"; and so on.
This notation is also used to reference individual properties from these collections. A property on the primary collection is referenced as "object. property_name"; a property on the first secondary collection is referenced as "object2. property_name"; and so on.
Subcollections are referenced by a subcollection property of the parent collection. The parent collection is referenced using the notation mentioned already. For instance, a property in a subcollection of the form's primary collection would be referenced by "object.subcollection_name.property_name".
