Master-Details example

Hi,

I've a view where there is a form (category entity) and a list with inline edition (service entity). In my model, I define that Category has a collection of Service and also Service has a navigation property to Category. What I'm trying is to add the new category with its collection of service. The odata config is set with enableDeepSave = false and withReferenceMethods = true.

If I create a new category with one service, the batch request looks like this:

POST http://localhost:20300/odata/ProductServiceTypes HTTP/1.1
Content-ID: 1
Accept: application/json;q=0.9, /;q=0.1
OData-Version: 4.0
Content-Type: application/json
OData-MaxVersion: 4.0

{"id":0,"createdById":0,"modifiedById":0,"dynamicProperties":{"displayName":{"en":"T"}}}
--changeset_b91b-bbbe-e01c
Content-Type: application/http
Content-Transfer-Encoding: binary

POST http://localhost:20300/odata/ProductCategories HTTP/1.1
Content-ID: 2
Accept: application/json;q=0.9, /;q=0.1
OData-Version: 4.0
Content-Type: application/json
OData-MaxVersion: 4.0

{"id":0,"productType":"General","canHaveSupplementsOrDiscounts":true,"canHaveContracts":true,"createdById":0,"modifiedById":0,"dynamicProperties":{"displayName":{"en":"T"}}}
--changeset_b91b-bbbe-e01c
Content-Type: application/http
Content-Transfer-Encoding: binary

POST $2/services/$ref HTTP/1.1
If-Match: *
Content-ID: 3
Accept: application/json;q=0.9, /;q=0.1
OData-Version: 4.0
Content-Type: application/json
OData-MaxVersion: 4.0

{}

You can see one post for each entity and the last one would be the association between the two entities, but its body is empty. Debugging the oDataProvider.js, it seems that with a collection it cannot set the @odata.id property. Is there a way to solve this?

I think the fix is quite simple: in oDataProvider.js, line 742, value is an array, inside are the items with __convertedRefence, adding something like and a little refactoring would do the trick:

if(Array.isArray(value)){ for(var i = 0; i < value.length; i++){ // same process as line 746 } }
