how to set userdata with JSON string

I encounter some problems with loadJSONObject() method in how to construct the JSON string to include user data. As I know, the user data is perfectly supported by loadXML() via a xml tag, '<userdata>', but I don't know how to do that with loadJSONObject() and JSON string. Can someone help me out? Thank you.

JSON reflect structure of XML object, so it will be

{id:0,item:[
   {id:1,text:"1111", userdata: [{ name:"some_name", content:"some_value"}] }
]}

Hi,

I'm having problems with getuserdata + json. I've send next json:

{"item":
   [
     {"text":"text1",
      "item":[{
               "text":"text1_1"
               "item":[],
               "id":"4",
               "userdata":[{"tel":"ddd"}]
             }],
      "id":"2",
      "userdata":[{"tel":"ddd"}]},
     }],
"id":"0"}

That prints perfectly, but when I raise 
Object_Organigrama_tree.getUserData(id,"tel") it returns "undefined". 
Is there any bug like in this post? http://www.dhtmlx.com/docs/products/kb/index.shtml?cat=search&page=1&q=4237&ssr=yes&s=json%20userdata
(Is the same as I'm aiming but for dhtmlxgrid)

Thanks

Change userdata syntax to the 
          "userdata":[{"name":"tel","content":"ddd"}]
with such way of data declaration it will work correctly.
