Betlista commented on WICKET-4535:
----------------------------------
I'll have to check your patches precisely. Your usage seems valid to me. I got
here, because I reported WICKET-5348 where IColumn changed from IColumn<T> to
IColumn<T, S> and it seems to me (according to your description), that T = S.
It seems to me, that while I want DataTable<ROW> - getColumns() returns list of
IColumn<ROW, COLUMN> while it should be IColumn<COLUMN> principially.
Now, when I checked sources I found I got confused with parameter misuse in
IColumn (PropertyColumn) and PropertyModel - in IColumn<T> (old version) T is
type of row, while in PropertyModel<T> T is type of "column".

> The Sort APIs use very generics inconsistently. Classes like
> SortableDataProvider, ISortState, SortParam etc do not all uniformly cater
> for sort properties other than string. There is a lot of unchecked casting,
> which is not really required, if generics were used across the board.
> Fixing this will probably cause API changes for 6.
