child of 04638closedDenisChenu Development  Array Dual Scale - Dual Dropdown - id contains # 



c_schmitz (administrator)

It does not work here in dropdown or radio. It is a problem that cannot be fixed easily because of the illegal field naming for dual scale questions.


Mazi (developer)

This is a rather serious issue since it holds one of my customer off launching a large and complex survey which should start in 5-7 days, so I would be very happy about a short term fix.

Let me know if I can help with testing or if you need additional information.


DenisChenu (developer)

It's an EM issue, and like all EM issue, it's hard to debug.

A quick possible javascript workaround:
- delegate a click function to td for table.question
- in this click function :
-- check the line clicked and get the sub question
-- check the input:radio:checked index and get the head with same index (the answers)
-> Doing own replacment

This don't use the id, then think it can work.

It's not the EM way, then it's a workaround.

Reminder sent to: Mazi

I have it, but actually it break min answers and max answers.

Mazi: can you try min answer and max answer on this question type and see if it's OK or not.

If it's not OK, i pull/close this one and put a new bug for min_answers and max_answers (and surely some other attributes)


Mazi (developer)

It seems that there is another bug with min and max answers, see


DenisChenu (developer)


Then it don't work actually with min/max .

Cool, pushing it this evening and i put another bug for min/max :)


Mazi (developer)

Great, thanks a lot!


DenisChenu (developer)

Fix committed to master branch:


DenisChenu (developer)

Yeah !

I'm happy ...

EM epxression in another question
Filter array for array_dual and from array_dual
min_answers and ma_answers
{self.sq_0} ans {self.sq_SQ001}

I rework a little the HTML and move whole js in external files. Just to remove the input hidden for EM in javascript to. Think this input can be competely removed with a better ExprMgr_process_relevance_and_tailoring function.

PS: Mazi : can you do some test please ?


Mazi (developer)

Thanks for your work, Denis.

I can't test right now because my dev system is currently broken. I hope to fix this next week.

Maybe Carsten can have a short look!?


Mazi (developer)

Denis, did the placeholders for dual scale questions change?

See this test survey:

The month is replaced correctly but the year is not shown. For the month {Dual_1_0.shown} is used which works fine, for the year {Dual_1_1.shown} is used which does NOT work.

Any ideas?


DenisChenu (developer)

Can you test with an letter in the subQ.

Because EM don't make difference betwwen _1 for scale and _1 for answer.

The Dual_A1_1 can be better


Mazi (developer)

I have changed the subquestion code from 1 to sq1 but this didn't solve the problem:

I also changed the scale codes to a1,a2,a3... and b1,b2,b3...


Mazi (developer)

Weird, at this survey it seems to work fine:


DenisChenu (developer)


Can you export this one:

Mazi and Denis-

For reference, the originally attached survey works fine in the final version of 1.92. The use of '#' in name and id attributes was fine there. There must have been some changes in 2.0 that introduced incompatibility with that naming.

I recommend regression testing these changes against all of the test surveys in /demos/surveys to ensure everything still works properly. For example, numeric scale codes should work (and used to work in 1.92). If these changes require that authors change to use scale codes like a1, a2, a3, instead of 1,2,3, then this set of fixes have introduced a regression.


Mazi (developer)

Requested survey attached.
