Extjs TreeStore data being ignored - extjs

Question

I think I have everything correct here :
A simple model :
Ext.define('js.model.MyModel', {
extend: 'Ext.data.Model',
fields: [
{
name: "name",
type: "string"
},
{
name: "type",
type: "string"
}
]
});
A tree panel with tree store :
Ext.define('js.packageDialog.ReleaseTreeView.PackageTree', {
extend: 'Ext.tree.Panel',
rootVisible: true,
singleExpand: false,
initComponent: function () {
//Ext.create('js.model.MyModel');
Ext.apply(this, {
store: new Ext.data.TreeStore({
model: 'js.model.MyModel',
"root": {
"expanded": true,
"name": "",
"type": ""
},
proxy: {
type: 'memory'
//data: data
}
}),
columns: [
{
xtype: 'treecolumn',
text: 'Name',
dataIndex: 'name'
},
{
text: 'Parents',
dataIndex: 'parents'
}
]
});
this.callParent();
},
loadData : function() {
this.store.setRootNode(data);
}
});
Some data :
var data = Ext.JSON.encode({
"children": [{
"type": "folder",
"name": "Photos",
"children": [{
"type": "JPEG",
"name": "wedding picture"
}, {
"type": "JPEG",
"name": "holiday picture"
}
]
}]
});
I put all this together. See the fiddle :

And nothing is shown in the tree panel. The columns are correct, however my loadData() method does not work.

I have got it to work like so:
var data = {
children: [{
text: "Photos",
leaf:false,
children: [{
"type": "JPEG",
text: "wedding picture",
leaf:true
}, {
text: "holiday picture",
leaf:true
}]
}]
};
Ext.define('js.model.MyModel', {
extend: 'Ext.data.Model',
fields: [
{
name: "text",
type: "string"
},
{
name: "type",
type: "string"
},
{
name:"leaf"
}
]
});
Ext.define('js.packageDialog.ReleaseTreeView.PackageTree', {
extend: 'Ext.tree.Panel',
rootVisible: true,
singleExpand: false,
initComponent: function () {
Ext.apply(this, {
store: new Ext.data.TreeStore({
model: 'js.model.MyModel',
root: {
expanded: true
//type: ""
},
proxy: {
type: 'memory'
//data: data
}
})
});
this.callParent();
},
loadData : function() {
this.store.setRootNode(data);
}
});
So specifying which are leaf nodes in the data, also properties like the root of your TreeStore was wrapped in quotes, so I just amended. The data is now displaying. This may not be the 'correct' answer but one I can offer so far for you. Hope it helps.
