Is this a bug in Dashboard Category Selector?

Question

Hello,

When using hosted feature service web map, the Dashboard Category Selector works very well. But once switch to map image service in web map, the "Show data table" button in Category Selector configuration does not work any more. Also, I can load the grouped categories, but only display "No Data" item, other checkboxes won't be displayed.

Does Dashboard Category Selector only work with hosted feature service not map image service? Or is this a bug?

Thanks

Rose

For those who may encounter the same issue, I have narrowed down the problem. The problem is with the map service using composite columns as unique indexes.

The workaround mentioned in this document works!
