Summary16203: Multiple choice questions with "other" optionactivated: Setting an answer as "exclusive" and selecting it gives an error message
DescriptionIf in a multiple choice question with a few answer options one option is set as "exclusive" AND the option "other" is activated, it is impossible to select that exclusive option and to continue with the survey. This scenario return an error message an request to fill in the input next to the "other" option. As this answer option is greyed out, it is impossible to fill something in. And furthermore, no input makes sense - because another option is supposed to be exclusive. I can reproduce this error with two different Limesurvey versions 4.x, whereas the exact same survey (I exported and imported it) in Limesurvey 3.x runs flawlessly. So this bug has something to do with the changes to version 4 I assume.
Steps To ReproduceSet up a multiple choice question with 4 answer options and activate "other" additionally. Set e. g. option 3 as "exclusive". Run the survey, select option 3 (exclusive, so only 3 is possible then) and try to continue. Limesurvey will return an error message, asking you to fill in the input next to "other" (which is impossible if 3 is selected).

An example: If you have the following answer options and set C as exclusive, it should deactivated and grey out all remaining option:
Other: [input ____________]

It works and if C is activated, all other options are greyed out. But proceeding to the next page is prevented as the input next to "other" is requested to be filled in with something. Which makes no sense and is not possible even if you try it.
Additional InformationThis is my first bug report. Please bear with me if something is not up to your expectations.

Dear Sir/Madam,

I have the same problem in LimeSurvey Version 4.1.18+200416.
When I implement the option "other" in a multiple choice question (type M), then the exclusive option (for option "I don't know") doesn't work and I can't proceed to the next page.
However, when I do not implement the option "other", then the exclusive option works perfect.
So, the problem lies with the option "other".

Do you have an idea how long it will take to fix this bug?

Thanks in advance for your efforts!

Kind regards,
