JsonRestStore+DataGrid: fetch data, count = rowsPerPage => rowCount = 2 * count

[Tiqu]

default (not set) DataGrid?.rowsPerPage (25)
+ dojox.data.JsonRestStore?
+ table, 25 rows

grid having 50 rows (25 empty), trying to fetch more on scroll

dojox.data.JsonRestStore?:

        _processResults: function(results, deferred){
            // index the results
            var count = results.length;
            // if we don't know the length, and it is partial result, we will guess that it is twice as big, that will work for most widgets
            return {totalCount:deferred.fullLength || (deferred.request.count == count ? (deferred.request.start || 0) + count * 2 : count), items: results};
        },

deferred.fullLength == null, ok, this is not partial request
returns {50, items}
DataGrid?.rowCount becomes 50 having 25 data rows…

Well, “deferred.request.count == count” != "partial result"
