I'm upgrading from Kendo 2015 Q1 SP1 (2015.1.408) where my grid with AutoComplete editor works fine, but when upgrading to any of the later versions (ex:Q2 SP1) breaks the editor, throwing "Uncaught TypeError: e._preselect is not a function" when clicking on a grid cell with the custom editor.
http://dojo.telerik.com/epowu shows the broken version (click on a "States" cell to see the exception and the placeholder text and not the correct value).
http://dojo.telerik.com/oHIse works fine using an older version.
Did I miss some breaking change?
Thanks
