MAInternalEditorComponent error

[John McKeon]

Hello Dario,
You have to initialize that instance variable indirizzoMemo (otherwise there
is really nothing to edit, no?)
You can do this most easily by adding it as a default for the
MAAccountModel>>descriptionIndirizzoMemo description:

default: MAIndirizzoModel new;
