Why am I getting the 'invalid slice method' error?

[Al]

I'm pulling my hair out with the the 'slice' error on something that looks so simple, using the code below

var dataSource = new kendo.data.DataSource({
    transport: {
        read: {
            url: "helper.php?action=data",
            dataType: "json"
        }
    },
    schema: {
        data: "zzz"
    }
});

dataSource.bind("error", function(e) {
    alert('error');
});

dataSource.fetch(function() {
    alert('fetch complete');
});

and my helper returns this json:

{"zzz":{"items":[{"type":"button","text":"Test"}]}}

 

I have tried with and without the schema set - please help?

Hi Al,

You can find my answer in the other thread: https://www.telerik.com/forums/'invalid-slice-method'-error-in-kendo-all-js#UkOibYXBRUGSOXJAwwPuNA.

On a side note, you can always add a post with the new information to the old thread, it's not necessary to open a new one.
