I am bulding an editor (class extends EditorPart) which has an associated
IEditorInput that provides model data (a domain object) to my editor. this
model data is shown as the text values within my editor Text objects. When
my editor becomes dirty and the doSave() method is called I want to save
my newly modified model/domain object but there is no clear way to tie the
text values of the Text objects to the domain object through the
IEditorInput object. What is the best way to get text data(value) from a
Text widget and set it that data into a domain object before saving? I
would hope I don't have to write a mapping of the Text inputs (widgets) to
my domain object.
Thoughts?

In my case the IEditorInput holds a weakReference to my model. Its true
that the architecture will hold on to the IEditorInputs. I think the
recently opened file list is one place.
