An update here.
I think the issue is that when a row (item is added to the collection) is added by clicking the Add New, the edit level of that object is set to 1. When we double click a cell on the row to activate the cell/row, the edit level goes up to 2. Now, when we try to cancel, the edit level of the parent collection is 1 and that of the child item is 2 and hence boom.
I have downloaded the ebook sample project tracker silverlight application.I get an Edit level mismatch exception on following the below steps
I'm having the same issue in our line of business application. I've followed some suggestions mentioned in earlier posts to set the ManageObjectLifetime to false. But, this has not helped.
Has anyone encountered this? Any help is appreciated.
