I understand that i can call the routine by using the form name of what is was instanciated as. Although this would seems easier in the formset to just call the routine THIS.PARENT.PARENT.ROUTINE.

Not really. A formset is a set of interrelated forms, usually sharing a data session. A form manager is an object that tracks and manages the form instances currently active at any given moment; it tracks each form, may hold certain state information about the form instance, and provides a unique object reference for the form which can be queried at any time. The form manager object deals with the form set as a whole; it provides a common point form form instantiation, and also provides an object with methofs that aplly to the collection of form instances as a whole. In many cases, it handles issue such as dispatching forms when one form is released; in my application, it's responsible for such things as enforcing single-instance forms, so that if the user tries to instance a single-instance form that is already active, the new instance is not started and the existing instance is activated. My form instance is also intimately connected to my aplication object; when the application object detects a shutdown request, it notifies the form manager object to attempt to either complete or revert any action in progress.
