    Default Unanswered: List in NestedList: Bug Sencha?

    Unanswered: List in NestedList: Bug Sencha?


    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

    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?

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

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

    Default Error in JSON

    Error in JSON


    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.

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

    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

    H
    ope this answers your question somehow.
