3 years ago Yes, I apologize but I made previous changes just a little bit before lunch in a hurry ;) I am fixing it right now. I still get a list from the query: this allow me to perform a particular check: in such a way I can control one more time that I don't get more than one result (in this case, there would be some problems in the insertion part). Then, if:
- I get more than one result: I throw an exception (an already managed one, the QueryException);
- I get only one result or zero: I return either a null object or the first element of the list
@alessandriniluca In getAllQuestionnaireAnsweredBySpecificUserAndProduct the questionnaire returned should be one,not a list, because one user should answer only one questionnaire
