TreeView checkboxes; checkChildren

[Mathias]

Hey i've a Problem with KendoTreeview. I build a TreeView with a json Datasource
[
{"id":1,"text":"foo","expanded":true,"items":
[
{"id":2,"text":"foo2","expanded":false,"checked":false},
{"id":3,"text":"foo2-1","expanded":false,"items":
[
{"id":4,"text":"foo3","expanded":false,"checked":false}
]
,"checked":false}
],"checked":true
}
]
JS Code:
$(document).ready(function() {
var dataSource = new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: servlet,
datatype: "json",
contentType: "application/json"
}

},
schema: {
model: {
children: "items",
id: "id"
},
data: function(data) {
var dataArray = eval(data);
return dataArray;
}
}
});

var treeView = $("#treeView").kendoTreeView({

dataSource: dataSource,
dataTextField: "text",
checkboxes: {
checkChildren: true
}
});
It works well but if i use checkChildren: true the pre check is not working. if i use only checkboxes: true without checkchildren pre check works but not check all childs. What is wrong ?

Hello Mathias,

The nodes, serialized in such way, conflict with the checkChildren functionality -- if the root node is checked, all its child nodes need to be checked, too. You can either serialize all nodes as checked, or not serialize the checked state for the child nodes (as seen in this Dojo snippet).
