Summary09369: Mandatory type N fields are validated upon first display
DescriptionMondatory fields of type N (numeric) are prematurely validated upon their first display - no 'previous' or 'next' form submit - resulting in an error message stating the field should only contain numbers. Browsing a grouped survey has the same result. See attached test survey.
Steps To ReproduceAdd a type N field to any survey and make it mandatory. No default value or any other special settings.
TagsNo tags attached.

No input-error added in question class.
Validated only in JS, like when you set Minimum value to 1 for example.

The error is not "mandatory numeric question is validated', the error is 'mandatory text question is not validated'.

I think it's a no fix needed.

Hi Denis,

Thanks for your reply. If you run the test survey don't you think it's strange that the numeric fields generate an error message and the text fields do not? Both are empty upon first display, both are mandatory and yet only the numeric fields complain about being empty.

IMHO someone taking a survey should at least have one chance to fill any field before validation messages should appear ...

There are some template issue here.

With citronade, and set hide tip to no : you don't see the error before click next.

And if you set the second question : not mandatory and minimum value to 2 : you see the same behaviour than mandatory :).

You have the near same behaviour with:
- Date question type
- Minimum answers for multi text and multi numeric
- etc ....

I can fix it easily, but not sure we want to fix it. I think i move mandatory to EM for 2.06, maybe ....

PS: you "don't" see the error at the first group.

Okay, thanks for your time Denis. I think I dig into the template (a custom variant of 'default') code and styles to see if I can find a workaround.

For the template you have:
.hide-tip : did hide tip is active or not
.good : it's OK
.error : it's an error.

.em_other_comment_mandatory : comment other mandatory
.em_regex_validation : regexp validation
.em_regex_validation.error : regexp validation with error
.em_default : it's your class to hide or show the tip.

But still, not sure what to do. Maybe : all tip accept empty + em_mandatory tip more for all :).

Then i think we can validate the page before accept submit.

Hi Denis,

Thanks again for your effort! With some searching in and tweaking of the styles I succeeded in achieving my goal: no more messages or red input backgrounds when a page with mandatory fields is shown for the first time.

I think it would be a great idea to put all validation logic in one place as it's quite complex and diverted now. As far as I've seen LS is not using AJAX-calls at the moment, IMHO this is a neat way to accomplish validation before submitting a form.

Although stricktly spoken the problem is not solved with my workaround, I will make a modest donation to the project, because I value LS and I think open source software in general should be supported ;-)

@McRoa : actually a lot of validation except mandatory is done in javascript. No need ajax.
You can validate a survey before allow click with js. Maybe some specific issue, but surely can be done.
