  Hi,

  I have an (angular2) FlexGrid with a linked oData collectiojn view.

  I want to edit values in-place in the grid, but attempting to move off an edited row generates an assertion in the console:

  ====
  
  ** Assertion failed in Wijmo: write operations require keys.

  I’ve tried subscribing to rowEditEndedNg and rowEditEndingNg and setting “Cancel” t true so I can intercept the event and perform the update myself, but to no avail so far - the assertion still logs and I can’t move off the row.

  What strategy do I need to adopt to work around this? Do I need to trap on a cell-by-cell basis?

  Hi,
  
  The primary keys should be set for OData keys property to allow CRUD operations.
  
  Please refer to the documentation:
  
  http://demos.wijmo.com/5/Angular/WijmoHelp/WijmoHelp/topic/wijmo.odata.ODataCollectionView.Class.html#keys

  Also refer to the OData/src/components/customers.component.ts file at

  EDIT: Sorry I see your second link answers the “how do I intercept a callback” question - thanks again,

  Thanks Manish - I was convinced I’d added a keys array in the right place, but apparently not. I’m over the assertion error now, but I’d still like to intercept the call to update the data.

  I believe I need to specify a callback on the oData options object but i’m struggling to find examples. Is there any documentation for the options object you can point me at? I come to a dead end when I follow the links from
