Sorting of table view - normal vs solutionmodel

[pilgrim]

Normally when you sort a table view
ascending = a, b, c, d, empty, empty, etc.
descending = empty, empty, d, c, b, a

A table view I created with solution model sorts differently:
ascending = empty, empty, a, b, c, d
descending = empty, empty, d, c, b, a
(empty fields always on top).

that i would find very weird, there is no difference between a solution model created form or a design time created form
And there is no relation to the sort at all, because the sort is done by sql. What is the sql that is send by those 2 commands? Are you building those 2 forms on the exact same table/data?
