title: jsTree - Setting href attributes in Json data
body: <p>Im trying to create a 'jsTree' treeview that gets it's data from a .Net webservice.
  Everything is working, except for the a-node's href attribute. Whatever I try, it always renders as '#'.
  As I understand from the documentation, all attributes in any data object get copied to the  a-node.</p>
  
  <p>Below is an example of my current json object. Can anyway figure out why the href attribute isn't copied to the nodes?</p>
  
  <pre><code>    [ { "attributes" : { "id" : "rootnode_2",
          "rel" : "root2"
        },
      "children" : [ { "attributes" : { "id" : "childnode_9",
                "rel" : "folder"
              },
            "children" : [ { "attributes" : { "id" : "childnode_23",
                      "rel" : "folder"
                    },
                  "children" : null,
                  "data" : { "href" : "http://www.google.com",
                      "title" : "Test_Below_1"
                    },
                  "state" : null
                } ],
            "data" : { "href" : "http://www.google.com",
                "title" : "Test_1"
              },
            "state" : null
          },
          { "attributes" : { "id" : "childnode_10",
                "rel" : "folder"
              },
            "children" : [ { "attributes" : { "id" : "childnode_24",
                      "rel" : "folder"
                    },
                  "children" : null,
                  "data" : { "href" : "http://www.google.com",
                      "title" : "Test_Below_2"
                    },
                  "state" : null
                } ],
            "data" : { "href" : "http://www.google.com",
                "title" : "Test_2"
              },
            "state" : null
          }
        ],
      "data" : { "href" : "http://www.google.com",
          "title" : "Glatt"
        },
      "state" : "closed"
    } ]

  <p>This is how I initialize the tree;</p>
  
  <pre><code>$("#jstreejson").jstree({
          json_data : {
              "data": treeObject
          },
          themes: {
              "theme": "apple",
              "dots": true,
              "icons": true,
              "url": "/Scripts/themes/apple/style.css"
          },
          plugins: ['core', 'themes', 'json', "json_data"]
      });
  </code></pre>
