I was working at Domain Model of my project and I tried to erase the MySQL database and create a new one, operation that I've already done lots of times. Suddendly I had an advertise of error of Webratio and in the Domain Model appeared an error for every entities and relationship, for example "The mapping database of the entity 'Argomento' is unspecified". The error remains when I try to create again the DB, when I create a new project, and also when I reinstall webratio. Anyone can help me?
Thank you everybody.
