KendoUI 2012.3 1315
Using jQuery from KendoUI.

Note: I did not have this issue with previous versions of KendoUI from August/September.

I'm running into a situation where a serverPageable DataSource returns an empty result and still does infinite loops.


From the changelog:
  • Fixed: Combobox falls into infinite loop if DataSource returns an empty result

JSON Data returned by server:
{ data: [], totalCount: 0 }
DataSource definition:
myDS = new kendo.data.DataSource({
        type: "json",
        pageSize: 15,
        serverPaging: true,
        serverFiltering: true,
        transport: {
            read: {
                type: "GET",
                dataType: "json",
                data: {
                    func: "myfunc"
                },
                url: "../myrest/"
            }
        },
        schema: {
            model: {
                id: "MY_ID",
                fields: {
                    MY_ID: { type: "string" },
                    SHORT_DESCRIPTION: { type: "string" }
                }
            },
            data: function(response) {
                return response.data;
            },
            total: function(response) {
                return response.totalCount;
            }
        }
    });
The issue is fixed if I pass a blank object into the data array to get this:
{ data: [{}], totalCount: 0 }

Hello Joel,

 
I prepared a simple jsFiddle demo, but was not able to replicate the issue with the latest official release of Kendo UI. Could you please check it and let me know if I am missing something?

Hi George, thanks for preparing that! I'll have to try out jsFiddle next time before making a post like this.

When I change your jsFiddle to have dataSource.transport.read.type = "GET" the combobox now shows as infinitely rotating. When it's POST as in your example, the spinning wheel isn't there any more.

I'll try to make a jsFiddle to reproduce the issue.

Hello Joel,

 
I will suggest you bind the error event and verify whether there is any error. 

Kind regards,
