How to use idSrc in many-to-many relationship where the intermediate table has double keys:
You have a "tblEngineer" table
tblEngineer
----------------
(PK) EngineerId
EngineerName
And a "tblTicket" table...
tblTicket
----------------
(PK) TicketId
TicketDetails
You now add a link table called "tblEngineerTickets" (or similar) which references the Ids of both the Engineer and their tickets...
tblEngineerTickets
------------------
(PK) EngineerId
(PK) TicketId
OtherValue
RESULT:
EngineerId | TicketId | OtherValue
------------+----------+---------
1 | 1 | 10
1 | 2 | 10
1 | 3 | 20
2 | 1 | 55
2 | 2 | 52
2 | 3 | 50

Hi,
The client-side code requires that the id source be just a single property in the data object. If you have a look at this example you will see the server returns the id to use for the row as a combined value (using a short hash).
Are you using any of the server-side libraries we provide, or something else?
