I have those same 3 lines of code
source.beforeprocessing(data);
dataAdapter.loadjson(null,data.results,source);
callback({ records: dataAdapter.records, totalrecords: source.totalrecords });
Page 1 is rendered fine, any other paging comes up with the same exception as mentioned in post 1:
The only difference I can see (same as Benji6996) is that the dataAdapater.loadjson prepares the data not from index 0 when not on page 1…
I’ll try going back to a previous version and see if that fixes it…
