TypeError: c[parseInt(...)] is undefined @ infragistics.ui.tree.js:29

I get this when I click on a node via

nodeClick: function(evt, ui)
                 {
                     alert( ui.node);
                 }

this is my tree

 var data = { "Text": "dataX", "Value": "dataX", "dataread": inData }

        //init code.
         $.ig.loader( function ()
         {
             inIUDiv.igTree( {
                 checkboxMode: "triState",//biState
                 singleBranchExpand: false,
                 dataSourceType: 'json',
                 dataSource: data,
                 bindings: {
                     textKey: 'Text',
                     valueKey: 'Value',
                     childDataProperty: 'dataread',
                     bindings: {
                         textKey: 'Category',
                         valueKey: 'AdvantageName'
                     }
                 },
                 nodeClick: function(evt, ui)
                 {
                     alert( ui.node);
                 }
             } );
         } );

also I can not check boxes under the root and if I check the root box I can not unchecked it or any items that were checked from it?
