I have a grid with no sortable columns and no default sorter, the method SearchGridHelper.getSortersFromJson() should return me an empty tab

[]

instead of a tab with a null value

[null]

.

Explanation (from line 1122 of SearchGridHelper) :

• firstSortable is set to null
• There is no sortable column and no default sorter.
• firstSortable is still null and defaultSorters is empty.
• A tab with firstSortable is returned (then [null]).
