Uncaught TypeError: m[dat[i].parent.toString(...)].children.push is not a function

[Todd Mc Brearty]

im receiving this error

Uncaught TypeError: m[dat[i].parent.toString(...)].children.push is not a function

my code is this.

$("#encodable-tree").jstree({

    "core": {

      "data": [

        {

          id: "108",

          text: "108",

          parent: "#",

          children: true

        },

        {

          id: "108/include",

          text: "include",

          parent: "108",

          children: true

        }

      ]

    },

    "progressive_unload": false,

    "progressive_render": true,

    "contextmenu": {"select_node": "true"}

  });

The line of JS that is getting the error is a generated file i guess? it's blob:http://...........
the area of the error occurs in this block

// 2) populate children (foreach)

for(i = 0, j = dat.length; i < j; i++) {

m[dat[i].parent.toString()].children.push(dat[i].id.toString()); //this is the offending line

// populate parent.children_d

p.children_d.push(dat[i].id.toString());

}

if i remove the second object the 108 directory shows but when i add it in it breaks with that error. i've been staring at it for almost 2 days and im sure it's something stupid.

Thanks

Hi,

Keep in mind you are using a lot of v.1 options mixed with v.3 options. Since you are using v.3 those will have no effect.
Here is your code with those options cleaned up:
http://jsfiddle.net/DGAF4/554/

The key to get this working is the children property which you have set to true. True means that children will be loaded at a later time, but at the same time - you are passing in the children (for the 108 node).
Simply remove this property - in the flat format which you are using the children property should only be used if you want to load the children at a later time.

Best regards,
Ivan
