Issue when no Time Period
This DF with only one single-fixed dimension and without time dimension shows no data (even though there is one data point): https://de-qa.siscc.org/vis?lc=en&df[ds]=qa%3Astable&df[id]=D&df[ag]=A&df[vs]=1.0&av=true&vw=tb
This is because the json query wrongly returns 0 observations: https://nsi-qa-stable.siscc.org/rest/data/A,D,1.0/all?dimensionAtObservation=AllDimensions&format=jsondata, see: dotstatsuite-core-sdmxri-nsi-ws#314 (closed)
