Error: $scope.treeInstance is undefined

I’m using AngularJS 1.4.2 and jQuery 2.1.4

my controller:

angular.module('app.controller', [
    'ngJsTree'
]).controller('AppController', function ($scope, $log) {
   //... 
    var selected_nodes = $scope.treeInstance.jstree(true).get_selected();
}

my template: <div js-tree="treeConfig" ng-model="treeData" tree="treeInstance">

and got: Error: $scope.treeInstance is undefined

I have the solution, the problem is to use treeInstance direct to the $scope as:

<div id="myTreeId" js-tree="treeConfig" ng-model="treeData" tree="treeInstance">

You have to initialize an object in the controller, for example:

function myCtrl(
        $scope) {
$scope.model = {};
...
}

After this, use the model in your template as: <div id="myTreeId" js-tree="treeConfig" ng-model="treeData" tree="model.treeInstance">

And in the controller: $scope.model.treeInstance, won’t be undefined.

@melino you must wait for the ready event of the jsTree before using the api instance. In the controller constructor it will not be available
