The statistics component is not working in my XWiki 5.2 installation.
"$xwiki.statsService.getActionStatistics('view', $scope, $period, $step)"
is returning 0 values, but the stats are enable, so much so that, other stats are working.
Furthermore, all the views/edit stats graphs are not working due this problem. How the activity data is not returning data then the graphs is not showing any value.
Evidence 1 - Graph is not showing any value
Evidence 2 - getActionStatistics is not returning any value
Evidence 3- Stats are working well.
In my first installation of XWiki, when I migrated to Oracle neither the statistics of "Daily connections" or "Active users" or "Recent sessions" were working well. They were returning the error “ORA-01843: not a valid month error”.
So I changed and configured a trigger in my oracle altering my NLS_DATE_FORMAT to "YYYY-MM-DD HH24:MI:SS"' and NLS_TIMESTAMP_FORMAT to "YYYY-MM-DD HH24:MI:SS.FF"' and they started to work well, see evidence 4. I don’t know if this kind of variables are related with this issue!
