I have sorted my datastore by mysql like: ORDER BY aaa, bbb, ccc

In the view I have a table with "Row Group" like:

Table::create(array(

...
"grouping"=>array(aaa),
),

))

that destroys the sorting of "bbb" and "ccc". I also tried sorting with -> pipe (Sort ()), which did not help

What am I doing wrong?

Thanks Stefan

Thank You!
