Hello,

When I try my code for a list pane as nonexclusive, I receive an error saying value NIL is not of type (mod some-number). I thought this meant that it didn't like my values and items as strings so I changed test to #'string= not #'eql. I still get this error when I click on the list to change the value.

Is this a known bug? Or am I missing something in my code?

It would be helpful if you attached the code in question.
