i try to add a new row in my grid, but it raises an error. In my datasource i work with $expand and have something like this:
Firstname, Lastname, AttributeID, Attribute (Name,Description, Value)
In my grid the columns show Firstname, Lastname, Attribute.Name, Attribute.Description, Attribute.Value
If i try to add a new row, the error is "can't read property 'Name' of null" and that is because of the expanding items.
Do you have an example how to work with adding new rows with expanding items? Or what am I doing wrong?
Thanks and regards,
