A "Multiple short text" question is used as an array filter via default answers filled via Expression Manager from previous answers. When the "Multiple short text" question is hidden via the option, the filter function is not working. My last impression was that "Hidden = Not answered" is not longer the default behaviour?

If you switch back and the change theses answers then default answers won't change.
I think this behaviour is intended, since once the question is shown and the prefilled answers are confirmed the default answers are no longer needed.

It would be interesting if questions could be made unanswered when skipping back and fourth through the survey. Any hint where to look?

You may be able to reset the answers with the EM Assignment Operator in an equation question. The equation question should be fired every time its page is visited.

Mhm. Looks interesting.
But how should that work? Something like QCODE=NULL? Or how is a reset of a question assigned via EM?

Would be a great way to allow users to skip back and forth without preventing the workarounds.
I found mostly warnings in the manual about the assignment operator

Thanks for the hint. I will do a bit of trial and error.

I'm not sure whether you can or need to set it to NULL. I was suggesting resetting it to your default answer.

Mhm. Monday seems to be a bad day to learn something new. You're right. NULL cannot be the correct way to reset the question to the default values. But what is the correct constant name to assign the default values again (like the question wasn't answered before)? Still haven't found a clue what to assign?

Another try to get the clue.

1. Question
Arrayquestion aq01

2.) Question
Multiple short text question "aq02"
The predefault answers are set with {if (aq01_1.NAOK >= "4" "Over4","")}

3.) Question
Arrayquestion aq03
Array filter: aq02

This is working fine as long as you don't skip back and fourth.
An answer once set to "Over" never changes back to unanswered. Even if the answer in aq01 is under 4.

I wonder how I could reset aq02 when someone is back on aq01.

Any idea how to use EM, Assignment Operator

to reset answer in question aq02?

To sum it up: How to clear and reassign default answers to a question, where default answers are based on answers of a question before.

BTW: What is the situation with the <= < > = with the default answer field?
www.limesurvey.org/manual/Expression_Manager#HTML_editor_issue

When using >= in the default answer field, you sometimes cannot get the default answer fields anymore.
The QA is showing errors "& gt ; = & quot ; 4 & quot ; & quot ; Over4 & quot ; , & quot ; & quot ; " .
But you won't see the fields to correct the errors anymore. Build Version 2.05+ Build 141003

Try using "gt" and "lt".

This was fixed for other parts so please test if you can still reproduce this at the demo.
If so .-> bug report.

Strange behavior. Today I was able to get into the default answers again.
"This issue is fixed after 2.06 build 140803" is displayed at that HTML_editor_issue.
What version is the demo? Was the fix back-ported to 2.05+? I am getting offtopic.

The demo runs the latest stable (=2.05) version.

Thanks, I will test and submit a bugreport if I can reproduce the problems.

Since the whole filtering is not working when hiding the question, it seems to be time for a break.

Is there a developer note or a thread where the default behavior of LS in terms of hidden questions is documented?

I don't think so, but there are several forum threads dealing with this.
