Hi Pariya,
An archetype may introduce a constraint so that during the recording of
data, you may use a quantity and one of the allowed units.
Just think about the difference between Fahrenheit and Celsius degrees
(Thomas Beale's example).
Wrappers do have access to ADL, but in these kind of situations, ADL
provides more than one option, so the wrapper can't know which unit it is
going to use. If there is only one option, the wrapper should automatically
use that. I don't think I've added that convenience, so that is probably
what got you confused.
Kind regards

Hello,
As far as I understand, in opereffa, *unit* of an item is not retreived
from the ADL file and should be set manually like :
pArchetypeWrapper.getElementAtNode(path).setUnitOfQuantity();
Am I missing something here, or is it the way it works?
I think since the unit and type of each item is already stored in the ADL
file, while parsing the ADL file to the ArchetypeWrapper, these types of
information should be set automatically in ElementWrappers in
that ArchetypeWrapper.
