Issue with using java inline script in OSWeb (Nov 2022)

MarkNieuwenstein

I am having issues using java inline script in experiment files that used to work fine in April 2022. This happens both on mac and on windows, in browser and local mode. I tried downloading an older version of Open Sesame, but get the same problem. It also happens with some of the very useful scripts I found here:

Counterbalancing: https://osdoc.cogsci.nl/3.3/attachments/counterbalancing-osweb-jatos.osexp

Collecting multiple keyboard responses as a single string: Filemultichar-input.osexp2.94 KB

Basically, anything including java (e.g., vars.condition = 'a') causes a problem. Any idea how I can resolve this?

Thanks in advance!

Oops, my bad: I had the script in the "run" section of the inline object instead of the prepare.

One issue remains though: The counterbalancing script, referred to above, generates an error: ArrowFunction is not supported by ECMA 5.1. This also happens when I run the experiment in a browser (google chrome on Mac OS Monterey).

I searched for this on the forum, and found this post https://forum.cogsci.nl/discussion/7182/counterbalancing-using-batch-session-data where it was said that the arrow function should work properly in a browser. However, it also does not work in a browser (I tried chrome and safari).

Hi @MarkNieuwenstein ,

Unless you are using a very old browser, the ArrowFunction should not yield a " not supported by ECMA" message. So perhaps some other part of the script is causing the error? Could you either post the exact error message or the experiment here?

Cheers,
