Filtering with the Column Heading Menu

Question

I have a master-detail IG and I want to filter with the column header menu (when I click on the column header). At the master table it works perfectly on every column (e.g. as you can see), but at the detail table when I click on the header, the column values are not loaded, just "...". (as you can see too)

What could be the problem? Is this a bug maybe?

Answer 1

I think it's a bug in the 5.1 version. I upgraded to 20.1 and everything works fine.
