Im trying to have my extension retrieve all marks selected in a table when clicking on one overarching dimension using getSelectedMarksAsync(). E.g. for a table containing a table with category "office products", select all rows for subcategory "pens". I can retrieve all marks selected when clicking on the mark directly or selecting multiple marks using Ctrl. However, when I try to do the aforementioned the Array returned by the function getSelectedMarksAsync() contains no data. Is this not possible or am I approaching it the wrong way?
