I’ve noticed a behaviour in the matrix type of question that can lead to a crash at the end of the survey.
If I have many items to add to the rows of the matrix, I simply use the Rows setting in the question settings. If there is a dot in my items I paste, and this item is selected when the survey is taken then it crashes.
Now it is my understanding that these are saved as key-value pairs and that the key cannot contain dot. But the same behaviour does not happen when I use the radiogroup type of question. So I am a bit confused as to the source of this error. Perhaps someone can shed some light on this?
Then I think it is important to stress that for the setting that allows us to enter multiple options at once we must:
Either respect the convention i.e. Row 1 | your option here
or your option here sanitised | your option here
I think I will be using the latter both for columns and rows as I want my data to show the real values selected rather than having something like the below and then trying to figure out what was selected
