Sorting bug?

Hi,

I have a relation from table A to table B on a contactID. The initial sort for the child table is on a date field and is descending. When I open the form with the child table grid it is sorted correctly. If I close the form and open it again it is now sorted in ascending order. Even after adding an explicit foundset.a_to_b.sort(‘datefield desc’) to the onShow() this still happens. How can I avoid this behaviour?
