Hi,
i have an virtual binded xml datasource in a grid. All works fine, but when the server has no records the browser has errors in Javascript because undefined values are in XML Data.
Sample:
<count>1</count><books><book><field1>Hallo</field1></book></books> -> This works fine
But if there are no books the browser reported errors:
<count>0</count><books></books>
Browser message:Uncaught TypeError: Cannot read property 'field1' of undefined

Hi,
thank you for your fast help.
You have attached OpenSource Files. I use the commercial version. Is this the same? When not can you send me the commercial version Files.

Is there an updated version of the (code above - of xml grid example) for latest version of Kendo UI? This version doesnt work when latest kendo javascript files are embedded and newer version of jquery. I just get following error,
Object doesn't support this action
that.reader = new kendo.data.readers[options.schema.type || "json" ](options.schema);

Could you please verify that you have included the kendo.data.xml file and all of the other dependencies are included correctly.

Is this not fixed in the latest build? See http://www.kendoui.com/forums/framework/data-source/datasource-bug---if-read-fails-it-is-not-possible-to-call-read-again.aspx#2095946

I believe the error that people are still seeing, as well as me, has to do with an empty grid and the grid columns footerTemplate attribute with aggregate data functions (i.e. sum). If I remove columns from the grid that contain aggregate data in the footerTemplate, the error goes away.
Error messages I receive:
Error messages I receive:
- Uncaught TypeError: undefined has no properties
- Uncaught TypeError: Cannot read property 'sum' of undefined

I figured out a way around this error. It involves doing a fetch on the the dataSource then checking the size (length) of the view:
var ds = new kendo.data.DataSource({ ... });ds.fetch(function () { var dv = this.view(); if (dv.length > 0) { var grid = $("#grid").kendoGrid({ ... }).data("kendoGrid"); } else { alert("No records found"); }});
