The week before the exit of 3.1 final, I moved a customer from 2.2.6 to 3.0.2.
I installed version 3 on his linux box, upgraded to 3.0.2, moved his db’s, imported the solutions in repository.
Now, after the customer noticed some strange behaviour, I see that all dataproviders setting (lookup values, custom values) has been wiped away.
I tried to re-import the solution, but I get a “xyz field property has not been changed” message.
What did it happen?
