I used this method:

The results are in the list (have tested in debug), but not showing in the browser. Got an error in the chrome console.

I can see in the page source the results too.

In the past I tried with an aggregate but no luck either.



no options given, and an error 

also in the source code I got results:

Hello Michael,

  • Please find attached the demo OML for your case. Kindly review the screen and preparation to get the data on the list  with multiple selection enabled. Also, it does not matter whether you are fetching the data from entity using aggregate or advanced SQL.

Thanks & Kind Regards,
