Arrays interferes with viewing attributes for item
I have a data-set for which one of the participants has an array value in one of the columns, when I try to view that participants it claims that there are no attributes:
but when I click on a different participant (one with no array value defined) I can see the attribute.
I think that this was already a bug in the past (perhaps not for the participant data-type) and was fixed.
