- Start move of statistics from being collected in form-fields to collecting these in the workflow objects. The original code was developed with less randomization (e.g. no x out of y alternatives) which requires that the formfields have to be reset multiple times (e.g. for multiple students in the exam protocol). The exam-protocol handler cleans regularly the form-fields, which caused also the deletion of statistics. Collecting these in the (exam) workflow is safe. - Collect correct and incorrect statistics per alternative. Since different students might see different alternatives calculating the successrate can only be performed by the students having seens this alternative.
