With a dashboard containing a set of maven2 jobs the test trend chart portlet constantly displays an empty chart - with axes and descriptions but no actual data. A test statistics chart on the same dashboard displays correctly.
From a quick look at the sources it seems that maven2 job runs do not have TestResultActions but SurefireAggregatedReports instead.
