List in NestedList: Bug Sencha?

[myput]

Hey,

For several days, i search to implement a list in a nestedlist, with Json file but it doesn't work.
In fact, i have my nestedList, and when i call the "getDetailCard" function, i call a list in the panel.

When i call the list like the API Documentation, it works (with data in store). But when i call a Json file by proxy in Store; it doesn't work. there is an infinite loading panel. But i checked, the Json is in good URL ...

I don't understand i did many list by this way, and they work fine.
It can be a bug?

Hi,

Have you tried a local json file?
see also: http://en.wikipedia.org/wiki/Same_origin_policy

Best regards,

hum yes,
my file is a local file, in a data folder, and i load this one by url: 'http://localhost:8888/app/data/file.json' .. Then i don't understand.

[bassjobsen]

btw for local files you can use:

proxy: {
type : 'ajax',
url : 'data/file.json',
reader : {
type : 'json'
},

Can you give us a sample of your store code and json data?

[myput]

Yep i tried that: url : 'data/file.json' But nothing better.

This is my Code:
The Main function with the nestedList:

	getDetailCard: function(item, parent) {
			var itemData = item.attributes.record.data;
			parentData = parent.attributes.record.data;
			detailCard = new Ext.Panel ({
				items: [WPApp.views.DirectoryItemListList]
			});
			detailCard.update(itemData);
			this.backButton.setText(parentData.text);
			return detailCard;
		},

Code of list:

Ext.regModel('WPApp.models.DirectoryItemListListModel', {
    fields: ['firstName', 'lastName']
});


WPApp.stores.DirectoryItemListListStore = new Ext.data.Store({
    model  : 'WPApp.models.DirectoryItemListListModel',
	proxy: {
		type: 'ajax',
		url: 'http://localhost:8888/WPApp/data/name.json',
		reader: {
			type: 'json',
		}
	},
	autoLoad: true
});




WPApp.views.DirectoryItemListList = new Ext.List({
	fullscreen: true,
	itemTpl : '{firstName} {lastName}',
	store: WPApp.stores.DirectoryItemListListStore
});

And the Json File

[
    {firstName: 'Tommy',   lastName: 'Maintz'},
    {firstName: 'Rob',     lastName: 'Dougan'},
    {firstName: 'Ed',      lastName: 'Spencer'},
    {firstName: 'Jamie',   lastName: 'Avins'},
    {firstName: 'Aaron',   lastName: 'Conran'},
    {firstName: 'Dave',    lastName: 'Kaneda'},
    {firstName: 'Michael', lastName: 'Mullany'},
    {firstName: 'Abraham', lastName: 'Elias'},
    {firstName: 'Jay',     lastName: 'Robinson'}
]

Like the API DOC.... I don't understand

[johnseelewis]

I believe you need to place your attributes firstName and lastName in quotes: "firstName" and "lastName". BTW, at first, I didn't notice the error in your JSON, so I ran it through an online checker at http://json.parser.online.fr I always do that to be sure my JSON is formatted correctly.

[myput]

OMG, yes thanks, i add "" like that, and i can display the list one time:

[
	{"firstName": "Tommy", "lastName": "Maintz"},
	{"firstName": "Rob", "lastName": "Dougan"},
	{"firstName": "Ed", "lastName": "Spencer"},
	{"firstName": "Jamie", "lastName": "Avins"},
	{"firstName": "Aaron", "lastName": "Conran"},
	{"firstName": "Dave", "lastName": "Kaneda"},
	{"firstName": "Michael", "lastName": "Mullany"},
	{"firstName": "Abraham", "lastName": "Elias"},
	{"firstName": "Jay", "lastName": "Robinson"}
]

But i have another problem.

When i have my nestedList detailCard, i can display my liste now.
But when i come back with the button, i can't click another time on an item ...
Just work one time and after i can't access to ma list.

Have you an idea?

[johnseelewis]

Not sure. I am new to this myself. I would check out the MVC example in this tutorial: http://www.sencha.com/learn/working-with-forms/

I was able to get the actual code from GitHub and I have been using it as a starting point https://github.com/senchalearn/Forms-demo

Hope this answers your question somehow.

[myput]

hum yes i'm reading that, but i don't know if something help me.
I just have a bug with my calling view i think,
but i don't know how to answer ...

[johnseelewis]

I might post a new question for that.
