Using the documented guidance and examples in other applications, we set up the report browser to show the specific properties we want in the data explorer column (pyReportEditorProperties). The properties are showing exactly as intended but we cannot add most column to the report. We can drag them to the report area and it show the orange vertical bar to indicate where it will be inserted but when you release the button nothing happens. This is true for all fields whether in the primary class or a page property with the exception of a couple date properties and the Pega specific props (pyID, pyStatusWork, etc) We are working in Pega 8.3 recently upgraded from 7.4.
