[Ext 5.0.1] TreeStore need help

Hi everybody,

I'am trying to use extjs 5 instead of extjs 4.2 for my new project.

I already built a treepanel with extjs 4.2 in this project and now i don't understand how it works in extjs 5 or what i did wrong in extjs 4. I tried to find something to help me since one week but i failed.

My problem is i can't populate my treepanel with my treestore by a json request.

The request is loaded but i think the data doesn't go in the store (storeTree.getCount() return 0).

I replace the root by a rootProperty but i think it's not enough.

I show you the code:

Code:

 var storeTree = Ext.create('Ext.data.TreeStore', {
        model: 'ArboModel',
        root: {
            id: 1
        },
        defaultRootId: '',
        proxy: {
            type: 'ajax',
            reader: {
                type: 'json',
                rootProperty: 'root'
            },
            url: url
        },
        lazyFill: true
    });


    storeTree.load({
        params: {
            node: 'root'
        }
    });
    storeTree.on('load', function () {
      //  console.log(storeTree);
alert(storeTree.getCount());
    });

The request returns me this JSON:

Code:

{"root":[{"children":[{"class":"models.Folder","entityId":2,"id":2,"idDoc":null,"leaf":false,"persistent":true,"text":"DRH"}],"class":"models.Folder","entityId":1,"id":1,"idDoc":null,"leaf":false,"persistent":true,"text":"UNILEVER"}]}

My tree panel :

Code:

var treeArboEnterpriseTree = Ext.create('Ext.tree.Panel', {
        title: 'Arborescence',
        width: 300,
        flex: 1,
        height: 250,
        xtype: 'treegrid',
        store: storeTree,
        rootVisible: false,
        collapsible: true
});

And my model :

Code:

Ext.define('ArboModel', {    extend: 'Ext.data.TreeModel',
    idProperty :'id',
    fields: [
        {
            name: 'id',
            type : 'int'
        },{
            name: 'leaf',
            type : 'boolean'
        }, {
            name : 'libelle',
            type : 'string'
        },{
            name : 'text',
            type : 'string'
        },{
            name : 'children'
        },{
            name : 'idDoc',
            type : 'int'
        }
    ]
});

I don't know how to use 'idProperty' in the model, how to config my treepanel, and how to config the treestore.

Thank you for helping !

Pierre
