Hi, I'm not sure where to post for incubator -- it doesn't have its
own mailing list.
I'm trying to use the PagingScrollTable widget from incubator. It
seems to work just great except I cannot get the columns to sort.
>From my understanding, there is a built-in quicksort implementation
that you can override if you wish. QS should work fine for me. I
have a simple table model here with two columns (firstName, lastName)
and the datatype is a string.
A sample onModuleLoad app using the PagingScrollTable is pasted below
that sets up some mock data. I may just be using the API incorrectly,
but I can't see it. Documentation is sparse.
Anyone have any insight on this??
Thanks in advance,
Davis
