Hello Stefan,

Thank you for reaching out to us, and for reporting this issue!

I was able to reproduce the error you outlined in your post and I have created a bug for the developer to address. You can follow it's progress at https://www.labkey.org/home/Developer/issues/issues-details.view?issueId=41970.

In the meantime you could try using the list webpart that the UI provides. Or if you needed to add this to a wiki you could consider using a LABKEY.QueryWebPart.

There are examples for usage in the document linked below.

Thanks,
