Is it possible to compose an MAReport to use fields
from different objects?
Yes. You can add columns manually using #addColumnDescription:. Just
make sure that you change the accessor object, so that it reaches the
other object. For example:
aReport addColumnDescription: (MAAddressModel descriptionStreet
accessor: #(address street); " calls #address on the
receiver, and on the result #street "
yourself)
You can also directly add such a description to the PersonModel if you
need it everywhere.
