Hi all

Smalltalk at: #ListValuePresenter

thanks.

I can offer an educated guess.  There probably once was a class called
ListValuePresenter, and it was refactored to be
SequenceableCollectionPresenter.  To avoid breaking older code that may have
used the old name OA added a global alias to the new class via the old class
name.  Something similar happened with CompositePresenter, it now points to
Presenter .

It looks as though ListValuePresenter has been removed from the system,
and a global inserted to avoid breaking code.

Have a good one,

Bill

Your guess is correct.
