Table not showing records from composition in separate tab


I have a tabsheet with 2 tabs in an edit screen. In one tab I display the main entity’s fields in a fieldgroup and in the second tab I show the related comments. The related comments are not shown but if I move the table to the first tab, it does show the related comments. The comment has a many-to-one association to the main entity and the main entity has a composition to the comments. I have a nested datasource created under the main entity’s datasource which is a collection datasource.

What am I doing wrong here?

Sorry, just ignore this. This was a height display problem and only showed the header which looked like there were no records shown.
