Batch editing should use multipart mime message

[Remco]

Hello,

I use kendo-ui datasource and grid with the SharePoint 2010 list odata service. I need to enable batch editing. As mentioned in this article:

http://msdn.microsoft.com/en-us/library/ff798339

the SharePoint 2010 list odata service supports batching though multipart mime messages. It appears kendo ui does batching by sending accross a request per operation type update/destroy/create (in what order?), where each request contains a collection of the objects involved, which requires a parameterMap as follows:

                parameterMap: function (options, operation) {
                    if (operation !== "read" && options.models) {
                        return { models: kendo.stringify(options.models) };
                    }
                }

Does kendo ui support the multipart mime message way of doing batching?

cheers

this is especially import as the SharePoint 2010 list odata service implements concurrency by round-tripping a concurrency token in http headers (an ETAG http header in a response and an If-Match http header in a request). Only by doing batching using a multipart mime message can you send the corresponding concurrency token for each operation in the batch, right?

I managed to get batch editing working for the SharePoint 2010 list odata/rest service with the kendo ui datasource using the Microsoft datajs library (http://datajs.codeplex.com/). It would be good though if I could combine the create, update and destroy operations in the same batch as well. It would be even better if I could combine the create, update and destroy operations of multiple datasources in the same batch. That would allow me to insert a new Order and its Order_Details in a single batch / unit of work / transaction.
