I have a screen Movies that has a table records that shows some info about the movies.

I have a RichWidgets\List_SortColumn in the "Title" column table header and in the "CDate" column table header of the table records to order when these table headers are clicked.

In the "Title" I have a RichWidgets\List_SortColumn with:
Source Web Block: RichWidgets\List_SortColumn
Column: "{Movies}.[Title]"
Destination: RefreshTable

In the "CDate" I have RichWidgets\List_SortColumn with:
Source Web Block: RichWidgets\List_SortColumn
Column: "{Movies}.[CDate]"
Destination: RefreshTable

In the preparation of the Movies screen there is an aggregate to get all the movies. This aggregate has the "Movies" entity as "Entities / Structures" and in order by there is:
"Movies.Title"
"Movies.CDate"

But its not working, when the table header is clicked the table records is not ordered. Do you know why?
