[open] opensesesame 27.2 error

WouterW

Hey all,

I programmed an elaborate program in opensesame 27.1, containing several multiple choice question forms.
This morning I wanted to run my study in the lab, in which they recently installed 27.2.

However, when I ran my program, I discovered that it had deleted everything in the multiple choice forms: they were completely blank. Moreover, when I tried to add stuff to the form and subsequently saved the program and closed opensesame, I got a 'cannot be written' error, so that when I reopened the file, the changes I made were gone, and the form was blank again.

Do you have any idea what happened? is it due to the version change?

Hi Wouter,

Would it be possible to paste the OpenSesame script that you try to use in you form item here?

Best,

Lotje

This is the script within one of the items.

set allow_multiple "no"
set description "A simple multiple choice item"
__question__
Neem je het aanbod van W. van den Berg aan? 
Als je dit niet doet krijgen jullie beiden aan het eind van het experiment geen geld voor deze ronde.
__end__
set button_text "Ok"
set advance_immediately "yes"
set form_title "Aanbod W. van den Berg"
set form_var "DomUltAanbod"
__options__
Ja, ik neem het aanbod aan.
Nee, ik neem het aanbod niet aan.
__end__

However, when I ran my program, I discovered that it had deleted everything in the multiple choice forms: they were completely blank.

In what sense are they blank? Is the script gone when you open the experiment in OpenSesame? Or does the experiment look fine in GUI but the forms don't appear when you actually try to run the experiment?

Moreover, when I tried to add stuff to the form and subsequently saved the program and closed opensesame, I got a 'cannot be written' error, so that when I reopened the file, the changes I made were gone, and the form was blank again.

Do you get this error immediately when you try to save the file? Or does saving appear to work fine, but you get this error when you close the program?

Do you have any idea what happened? is it due to the version change

It's difficult to say with certainty, but there are not many differences between 0.27.1 and 0.27.2. So my first guess is that the problem lies elsewhere. I'm not sure where though, but we'll figure it out.

Cheers,

"In what sense are they blank? Is the script gone when you open the experiment in OpenSesame? Or does the experiment look fine in GUI but the forms don't appear when you actually try to run the experiment?"

They are completely blank in the flowline already. Both the script and the 'form screen' (so the screen in which you can for example tick the clickthrough-options on and off).

"Do you get this error immediately when you try to save the file? Or does saving appear to work fine, but you get this error when you close the program?"

I get the error when I close the program. So, if I save the program after making alterations to the forms, it doesnt give an error. However, if I want to close the program after saving it, it asks me to save it again, and if I do, it crashes. When I restart again, all the changes to the multiple choice forms (including those I saved without closing it) are gone.

Hmm, I'm afraid it's still not clear what goes wrong. If the problem still occurs, could you please provide all details that could possibly be relevant and upload the experiment somewhere?

For example:

• What operating system are you using?
• Which package of OpenSesame do you use, or are you running from source?
• Does this happen with all experiments, or only this one?
• Are there error messages in opensesame.exe.log (in the OpenSesame folder)? And if so, what are they?
• Anything else ...
