Keeping sort info when doing remote paging

[eranlo]

I'm trying to do remote sorting and paging on the server.

I may be missing something here, but when I use the pagingSource in the PAGER plugin, it seems like the function I pass is being called with the paging data, but without the sorting info. So, for example, if I sort my data by name alphabetically, the server gives me the first 20 results sorted by name. If I try to go to the next page, my function gets called with pageIndex of 1, but I have no context of what the last sorting info has been (sortParams is empty) so I can't pass it on to the server.

If, on the other hand, I click on the column header, the sortingSource function gets called with the sortParams, but it also has the latest paging info.

I tried to use a custom pager but couldn't figure out how to get access to the sort info. It looks like Column, which calls doSort has the pager state, but the page toolbar Button, that calls setPageIndexAsync does not have the sorting data.

Is there an example for passing the sort state to the paging call? It seems to me that this should be a pretty common use case.
