Re: Server Side ColumnSorting with AsyncDataProvider

same problem here

i won't bother to create another Map object, instead, I @override the
toString() function for TextColumn class. By calling
cellTable.getColumnSortList().get(0).getColumn().toString(); and i can
get back the pre-defined string.

hope gwt group can enhance the Cell Table in the future.
