I have uploaded to ArcGIS Online an Excel spreadsheet with a couple of hundred rows, which is then published as a hosted table. There are two sheets in the original xls, but I select one of them when uploading.
I can successfully use the hosted table as a data source for ArcGIS Dashboards. However, in ArcGIS Dashboards Beta, when I select the hosted table as a data source, it asks me to select a sub-layer, but the sub-layer droplist is empty.
