i agree, but each component sets the object individually. with a
ComponentController (name changed for marketing reasons ;-) ), the controller
is asked to update the model, it can then query m components and set n values.
also, i think of IModel as an adapter to the actual model, so it reflects the
underlying model 1:1.

you have the context already - setObject(Component context, Object o)

it will be the mediator between the components and the model (like

if the framework interacts with the manager, rather than directly
with the components, for the purpose of updating the model, then one
manager can be associated with two components. thus, when its
'updateModel()' method is called, it will interact with the two
components, query their raw value and set it in the model.
this allows an n:m relationship between components and model values.
