​I've been trying to create a checkbox tree in my settings for a widget.

The checkbox tree docs are here: http://thejekels.com/dojo/cbtree_AMD.html

To get the data into the tree I'm using the code below. The data array is not what I'll be using in the end product. The problem I'm having is that the data property of the store is always null. The _jsonData property of the store object has the array in it though. Can anyone see what I'm doing wrong?

var data = [{ id: "earth", name: "The earth", type: "planet", population: "7 billion" }];

               //var data = result;

               var store = new ItemFileWriteStore({ data: data });

               var model = new ForestStoreModel({

                   store: store,

                   query: { id: "earth" },

                   rootLabel: "Layers",

                   checkedRoot: true

               });

               var tree = new Tree({

                   model: model,

                   id: "MenuTree",

                   branchIcons: true,

                   branchReadOnly: false,

                   checkBoxes: true,

                   nodeIcons: true

               });

I think I need to call fetch() on the store before using it in the model.

I've made some progress. The following code will display a rudimentary tree, as shown. The checkboxes don't show for some reason and I can't get the parent-child hierarchy to display.      

               var layers = {};

               layers.label = 'name';

               layers.identifier = 'name';

               layers.items = [

                 { name: "Family", type: "root" },

                 { name: "Abe", type: "parent", parent: ["root"], hair: "Brown" },

                 { name: "Jacqueline", type: "parent", parent: ["root"], hair: "Brown" },

                 { name: "Homer", type: "parent", parent: ["Abe"], hair: "none" },

                 { name: "Marge", type: "parent", parent: ["Jacqueline"], hair: "blue" },

                 { name: "Bart", type: "child", parent: ["Homer", "Marge"], hair: "blond" },

                 { name: "Lisa", type: "child", parent: ["Homer", "Marge"], hair: "blond" },

                 { name: "Maggie", type: "child", parent: ["Homer", "Marge"], hair: "blond" }

               ];

               var store = new ItemFileWriteStore({ data: layers });

               var model = new ForestStoreModel({

                   store: store

               });

               var tree = new Tree({

                   model: model,

                   id: "MenuTree"

               });

               connect.connect(tree, "onCheckBoxClick", model, that._checkBoxClicked);

               tree.placeAt(that.checkboxTreeDiv);

Hi Robert,

I've tried some of the demos here: cbtree/demos/store at master · pjekel/cbtree · GitHub

Couldn't get them to work though. Searching Stackoverflow and Geonet for discussions about the cbtree is a joyless experience. I think maybe one question was posted on Stackoverflow. I'm coming to the conclusion that this is not a well used and tested object.

Andrew,

    The sample I provided above is based on the cbtree samples but I have tested it and made sure that it works with the JS APIs dojo and does not require dojo to be installed on your local machine.

Hi Robert,

Thanks for you help. The problem I have with the sample is that I'm getting

these errors:

- GET http://localhost:62919/setting/cbtree/Tree 404 (Not Found)

- Uncaught Error: xhrFailed

I believe the path to cbtree/Tree is correct, so I can't see why I get that

error.

Andrew,

   So do you have the whole cbtree library in your widget setting folder?

Thanks, Robert. I ended up altering the init.js file like so:

dojoConfig = {

      parseOnLoad: false,

      async: true,

      tlmSiblingOfDojo: false,

      has: {

        'extend-esri': 1

      },

    packages : [{ // this is the package I added

        name : "cbtree",

        location : window.path + "libs/cbtree"

    }]

};
