> If multiple sort constraints are passed to CollectionGridDataSource#prepare, a Comparator is created for every constraint and they are applied one after another. That leads to only the last comparator affecting the resulting order which is at least confusing.
> The Comparators should be combined into a chain, each element returning either its own result if it is different from 0 or the next element's result. See also http://stackoverflow.com/questions/1421322/how-do-i-sort-a-list-with-multiple-sort-parameters
