Form: Paging isn't working with autocomplete field

Hi
in a multiple record, editable grid view or editable grid FORM, i have a column which is an Integer, referenced to a table. When i do this column as an Integer, then everything in the form works. When i change this column to a “autocomplete number” field with a lookup to my “Users” table, then the navigation is not working at all. My Users table has 3’500 records.

When i press the “Page 2” Link, nothing happens. Also when i press the arrow key right to move to the next page, nothing happens.

Can someone reproduce this?

Best regards
Steve
