                                  • Hi,
                                    In the project there is a building like Master, MasterDetail and MasterDetail-Child. 
                                    I open Master View with preview mode. I open the masterdetail view in the master file with the preview mode as well. But I get the following error when I open MasterDetailChild view with Preview from MasterDetail. This error occurs when we add the aggregated property to the collections
                                    (My Project Version :

                                    To run the sample Project follow the following steps;

                                    1-Click EmloyeeM (with preview mode not edit mode)
                                    2-Click Any EmployeeD From EployeeM Detailview (not edit mode)
                                    3-Click Any EmployeDChild From EmployeeD DetailView (not edit mode)

                                    The error occurred:

                                    Type:       Exception

                                    I have attached a sample Project which you can see the behaviour i have tried to explain above.
                                    Do you have any idea what could be causing this problem?
