nativeeditor status

When i insert a new row in my grid and click save, the nativeeditor status is empty instead of insert. What can be the possible reasons?

Quite strange situation. DataProcessor handles onRowAdded event , so if row was added by public API ( addRow command ) and dataprocessor was already attached to grid - status must be set correctly.
Are you executing some other operation against row, before sending data to server ( in theory changing row ID before sending it to server may cause similar problem) ?
Which ID you are using for new row? it must not be [ null | 0 | undefined ] value
