Updated : usage of .question seems the issue

I am sorry but can you please explain what the error is?

See the screenshot :
count(self.NAOK) == 2
count(self.question) == 2
BUT
if(count(self.NAOK) == count(self.NAOK), 'OK','KO') == 'KO

I doubt that count(code.question) is a valid expression - and unless the question text is completely empty it should always return 1.

Anyway in the case of that.Q00.question I would expect it to return the question text of the main question.

But in this case it returns the question text of the last subquestion.

No, because i use self : see https://manual.limesurvey.org/Expression_Manager#The_reserved_.27this.27.2C_.27self.27.2C_and_.27that.27_variables
It's a totally valid expression.

It work without issue when use it in PHP, but not comparing, where seems to use JS.

In fact : the issue is really this : count(self.question) is OK via static variable, but not via dynamic variables.

I have the same issue for https://github.com/LimeSurvey/LimeSurvey/pull/1256 and QCODE.help (or idea of function without JS equivalent : getStatOfQuestion ).

In your example file (v2) you were not using self. You were using that.Q00.question

Maybe you should start over with a more simple example file.

code. question always gives back the question text.
I am still not sure what you want to count here.

self and that.Q00 is same inside Q00 question

See lss : OK in next page, broken in same page.

Fixed lss : have error before, but same issue

I am still not sure what you want to count here.

Number of question … there are difference in PHP and in JS : then there are issue …

If the value of count(code.question) is undetermined because the expression is invalid in itself then it may well be different in JS and PHP.
I can't find anywhere in the documentation that count(code.question) should work or is valid.

No need documentation : (if Question code are valid)
count(QCODE.question) == count("my question") == 1
count(QCODE_SQ01.question,QCODE_SQ02.question) == count("Sub question 1","Sub question 2") == 2
count(that.QCODE.question) == count(QCODE_SQ01.question,QCODE_SQ02.question) == 2

The issue is 483539X527X7030SQ01.question is NOT set in ExpressionManager javascript var …

Maybe EM need a «this is a fixed var, don't take it from javascript»

Okay, I can agree on that one. So please close this one and reopen a new issue with

"'qcode.question' and subqestioncode.question text not valid / set wrong on in-page EM expressions"

Thank you!

The strange issue is : count(QCODE.question) is OK but not when comparing or make evaluation with value in page.

count(that.QCODE.question) == count(QCODE_SQ01.question,QCODE_SQ02.question) == count('Sub question 1','Sub question 2') == 2
is OK.
Not (count(that.QCODE.question) - count(that.QCODE.NAOK))

It's the reason of the exact title …

If you look at the content of qcode.question then you will see that it is not okay.

Looking at HTML : LEManyNA('483539X527X7030SQ01.question', '483539X527X7030SQ02.question')

It's a minor issue, but still an issue :). And this make big change on EM javascript (allow to have «fixed var», not updated by JS).

If you look at the content of qcode.question then you will see that it is not okay.

I don't understand ?
{list(that.Q00.question)} seems OK.

Why would you do count() on QCODE.question? It's a text field, no? Not an array.

See https://bugs.limesurvey.org/view.php?id=14817#c51773

count(QCODE.question) must return 1, always.

See https://bugs.limesurvey.org/view.php?id=14817#c51782 too
{list(that.QCODE.question)} == {list(QCODE_SQ01.question, QCODE_SQ02.question)} = Text of subquetsion 1,Text of subquestion 2

count(QCODE.question) must return 1, always.

Or invalidate the expression: "count() requires an array, found string"

With {if(count(self.NAOK) == count(self.question) ,"OK","")} : the attended behaviour are if all answer are filled : get OK, else get "".

But that's the same as count(self.NAOK) == 1?

Or invalidate the expression: "count() requires an array, found string"

Not the case today, and clearly : User wait 1 … Like {count(QCODE.NAOK)} return 0 o 1.

Manual :

count the number of answered (non-blank) questions in the list

But that's the same as count(self.NAOK) == 1?

No : count(self.NAOK) return 0 if answer is empty …

It' in the lss and in the screenshot … https://bugs.limesurvey.org/file_download.php?file_id=11562&type=bug

But that's the same as count(self.NAOK) == 1?

Yes, BUT ; with count(self.NAOK) == count(self.question) : you can use it in all quetsoion. Just copy/paster don't care of number of answers.

So QCODE.question is an array IF there are subquestions??

No : that.QCODE.question

QCODE.question didn't exist if it's an array (except with the plugin).
