Relationship Business Object Fields are shown as [object object]

Summary:

We have a BO Employee_Info

We have a Relationship BO Employee_Contact having two Fields ; Employee_Contact_Name and Employee_Contact_Date_of_Birth

Employee_Info ; Employee_No ,Employee__Name are fetched correctly

To Fetch the Employee Contact Data in a Table Column Field we have added as:

EmployeeContact.items[0].Employee_Contact_Name

EmployeeContact.items[0].Employee_Contact_Date_of_Birth

It returns the data as [object object] in the Page for the bothy EmployeeContact BO

Also for the Date of Birth the Type is shown as String in the Relationship so we need to fetch it as Date.
