Too Much Recursion

[John Stephens]

When I bind to a remote data source that returns this data:

[{"Id":1,"Name":"N0014E0","Devices":null},{"Id":2,"Name":"N0014E1","Devices":null}]

I receive a Too Much Recursion Error.

Modified code from the demo:

var serviceRoot = "http://localhost:8211";

 

homogeneous = new kendo.data.DataSource({

  transport: {

    read: {

      url: serviceRoot + "/reporting/JsonControllers",

      dataType: "jsonp"

      }

    },

    schema: {

      model: {

        id: "Id",

        name: "Name",

      }

    }

});

 

$("#treeview").kendoTreeView({

    dataSource: homogeneous,

    dataTextField: "Name"

});

Hello John,

In order to bind the treeview properly, you need to use a HierarchicalDataSource. Here is a jsbin sample that mocks the data and binds the treeview. I could not reproduce the "too much recursion" error, but it is something that we have encountered before and fixed it in the latest internal builds -- you can use them to address the issue.

All the best,

I am trying to load data to a treeview but I get "too much recursion...f(this._isServerGrouped()){var i,o=t.toJSON();return e.length&&(i=e[e.length-1])..."
The treeview is inside a bootstrap container, and browser is firefox.

html
    <div class="container">
        <div class="row top-buffer">
            <div class="col-md-4 ">
                <div class="treeview-back">
                    <div id="treeview111" style = "height:200px;" class="demo-section"></div>


Javascript is:
<script>
        var serviceRoot = "http://localhost:37790/Home";
        var homogeneous = new kendo.data.HierarchicalDataSource({
            transport: {
                read: {
                    url: serviceRoot + "/GetIndicatorsGroups",
                    dataType: "jsonp"
                }
            },
            schema: {
                model: {
                    id: "GroupId",
                    hasChildren: "HasIndicators"
                }
            }
        });

        $("#treeview111").kendoTreeView({
            dataSource: homogeneous,
            dataTextField: "FullName"
        });
</script>

Controller is:

        public JsonResult GetIndicatorsGroups()
        {
            var context = new DashboardEntities();
            context.Configuration.ProxyCreationEnabled = false;

            var query = context.DashIndicatorGroups.Include(i => i.DashIndicators)
                .Select(group => new
                {
                    GroupId = group.IndicatorGroupId,
                    FullName = group.Name,
                    HasIndicators = (group.DashIndicators.Count > 0)
                });

            return Json(query, JsonRequestBehavior.AllowGet);
        }

I hope somebody could help me with this issue.

Please provide a sample that shows the issue. Here is one to get you started.

Alex, 

I think i have a conflict between kendo.web.min.js and kendo.dataviz.min.js.
Could you try in your sample adding following line, below  kendo.web.min.js, declaration 
    <script src="http://cdn.kendostatic.com/2013.3.1119/js/kendo.dataviz.min.js"></script>

In my case it show "loading ... " when

In my application ocurrs something like when I have 
    <script src="@Url.Content("~/Scripts/kendo/kendo.web.min.js")"></script>
    <script src="@Url.Content("~/Scripts/kendo/kendo.dataviz.min.js")"></script>
and in addition show the error: 
TypeError: s is undefined...tor(e);return function(e,n){var i=t(e),a=t(n);return i&&i.getTime&&a&&a.getTime&... in kendo.web.min.js

http://jsbin.com/IlAtOLU/1/

But when I delete the kendo.datavis.min.js  declaration it works !

Thanks
William Castro.

Hello WIlliam,

Yes, kendo.web.js and kendo.dataviz.js both include the core framework. If you want to use both of them on the same page, either use kendo.all or build a custom distribution through the custom download builder. See the javascript dependencies help topic about more information.
