When working with existing project in Eclipse, starting roo-shell, causes all changes in database to be reflected in aj and web files.
Instead, there should be a settable option to inhibit this behavior. When adding new tables, relations, user does not want to re-gen code
for existing views, controllers and models. User wants to add just new entities, controllers, and views.
As it works now, user is forced to remove number of files and re-fetch them from his source control (restore to previous source version).
