Hi William, As per the error [Unable to call SAVE-ROW-Changes(). Failed to create query for BEFORE-TABLE], this could happen when a Save or Submit operation fails from client (mobile and web app) when the Business Entity possess multiple tables without SUBMIT operation. As Edsel suggested we need to have readLocal and autoSave properties that need to be set at the JSDO datasource level in order to achieve Hierarchical or Nested grid functionality. - When readLocal is set to TRUE, then the data is read from the JSDO via the JSDO memory - When readLocal is set to FALSE, then the data is read from the OpenEdge backend. Note : Please note that, readLocal() and autoSaveChanges() methods available at the JSDO level and are different from the readLocal and autoSave properties available at the JSDO Datasource level. Please find attached Telerik Platform mobile app sample followed by Business Entity class file which demonstrates the usage of hierarchical Kendo UI grid with listview control. Please replace with your service information (which possess CRUD+Submit operations) in the jsdoSettings.js file located in the project under scripts directory. - This sample uses the same JSDO instance for both parent and child datasources - Possess usage of readLocal and autoSave properties at JSDO datasource - Uses PDS template which is available as part of Telerik Platform - Possess JSDO 4.2 Hope this helps. Thanks and Regards, Anil Kumar.
