NPE

[keeganmcbride]

This URL throws an NPE: http://wapps.islab.uom.gr:8084/JSON-QB-REST-API/table?dataset=http://id.mkm.ee/statistics/def/cube/crashes_day_time&measure%5B%5D=http://id.mkm.ee/statistics/def/measure/number_of_crashes&row%5B%5D=http://id.mkm.ee/statistics/def/dimension/day&http://id.mkm.ee/statistics/def/dimension/time=http://id.mkm.ee/statistics/concept/time/09

It seems that in the crash dataset anytime the "time" dimension is a number starting with 0 (00 through 09) an NPE is thrown (see stacktrace).
