Displaying nested infotable on row selection

Hi,

I have a datashape that contains infotables, and some of these infotables also contain infotables. My goal is to display the "root" infotable in one grid, and the nested infotable in another grid when the selected row changes in the root grid.

The images below display my current configuration that is not working:

I've read about similar situations but have not been able to solve it. According to https://community.ptc.com/t5/ThingWorx-Developers/Selected-row-s-problem-with-infotable-in-infotable/m-p/550168#M28657 this was solved in TWX 8.3.0 but I am on 8.3.2 and there is nothing showing the nested grid when selecting a row.

I am using advanced grid version 4.0.1, but have also tried advanced grid 4.2.0 and neither work.
