Combobox infinite looping in 2012.3 1315

[Joel]

Chrome 24.0.1312.57m
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,
