recline js recordCount doesn't update

Question

Start with this:

var arr = [{a : 1}, {b : 2}, {b : 2}, {b : 2}]

var dataset = new recline.Model.Dataset({
                  records: arr
                  });

dataset.recordCount // returns 4

dataset.records.reset() //all records are gone

but dataset.recordCount is still 4

Answer 1

Remember that the records attribute on a Dataset just represents a partial "window" of records from the full set of records stored in the associated backend.

Changing records will have no affect on the backend unless you save and requery.

Remember: recordCount is total number of records in the backend not the total in the .records list.
