Summary	20421: Question attributes should be sanitized when you change the question type ...
Description	When you change the type of an existing question (by selecting a new question family), the attributes that has been initialy chosen (for the first question type) can override the attributes chosen for the new question type. See example below …
Steps To Reproduce	1 - Create a new question with a 'table' type (type F) 2 - Add 3 subquestions like this : A, B and C 3 - Add 3 answer options like this : 1, 2 and 3 3 - Select random order in the display settings of the question 4 - Save the question Content in the lime_question_attributes table at this moment : qaid \| qid \| attribute \| value \| language ---------+--------+----------------------+-------+---------- 1682391 \| 639573 \| min_answers \| \| 1682392 \| 639573 \| max_answers \| \| 1682393 \| 639573 \| array_filter \| \| 1682394 \| 639573 \| array_filter_style \| 0 \| 1682395 \| 639573 \| array_filter_exclude \| \| 1682396 \| 639573 \| exclude_all_others \| \| 1682397 \| 639573 \| random_group \| \| 1682398 \| 639573 \| em_validation_q \| \| 1682399 \| 639573 \| em_validation_q_tip \| \| fr 1682400 \| 639573 \| repeat_headings \| \| 1682401 \| 639573 \| answer_width \| \| 1682402 \| 639573 \| random_order \| 1 \| 1682403 \| 639573 \| hide_tip \| 0 \| 1682404 \| 639573 \| hidden \| 0 \| 1682405 \| 639573 \| cssclass \| \| 1682406 \| 639573 \| use_dropdown \| 0 \| 1682407 \| 639573 \| printable_help \| \| fr 1682408 \| 639573 \| page_break \| 0 \| 1682409 \| 639573 \| scale_export \| 0 \| 1682410 \| 639573 \| public_statistics \| 0 \| 1682411 \| 639573 \| statistics_showgraph \| 1 \| 1682412 \| 639573 \| statistics_graphtype \| 0 \| 1682413 \| 639573 \| image \| \| 1682414 \| 639573 \| save_as_default \| N \| 5 - Edit the question and change its type like this : multiple choice bootstrap button (type M) 6 - The 3 subquestions are still here 7 - Be sure that the normal order is selected in the display settings of the question 8 - Save the question 9 - Preview the question ...

So, when you change the type of a question, it would be nice to keep the attributes related to the new question type and to delete in the database (table 'lime_question_attributes') the attributes only related to the old question type

DenisChenu 2026-02-10 10:21 developer ~84200	My opinion 5 - Edit the question and change its type like this : multiple choice bootstrap button (type M) 6 - The 3 subquestions are still here 7 - Be sure that the normal order is selected in the display settings of the question The point 7 must be "Be sure that the random order is set" : If question types have the same attribute, they must be the same as the previous question. It was the behavior in 3.X
