Results of the editing in EditorWidget are not saved. After adding new element  I click OK. Fiddler does not show errors. But in table in geodatabase the result does not appear. And on the last attachment - what fiddler show after edit feature in arcgis.com - all edits save normally.
What next step I can do?
