If there are Accepted Answers, those will be shown by default. You can switch to 'All Replies' by selecting the tab below.
If you're sure the query returns only one value (or you just one the first one) just click over [ALL] and another element will be added to the list called "Object[0]" that can be mapped to a single-valued attribute/variable.
Since the DQL query is not guaranteed to return only one row, it is not allowing to map the output to a single-valued attribute.
So, try using a function other than COPY for mapping.

Yes I solved the problem by adding a first element on the collection like Alvaro said .
Thank you both for your replies.
