- when a map report is evaluated it returns an array instead of an object
- one entry in the array contains the key and value of one data point
- the rest-api is adjusted as well
In a json object the order is not preserved. However, we still use the order of the result e.g. when the user sorts a table. This works in most cases, but there are some edge cases where this just doesn't work. For instance, grouping by an integer variable and then sorting the by key.
