    Default Ext.data.proxy.Memory Errors

    Ext.data.proxy.Memory Errors


    I really like 2.0 so far, but I'm stuck getting a simple list to work. The following code is taken directly from the List code in the 2.0 Kitchen Sink example with a few minor tweeks to get it working independently.

    Here's the error I'm getting:

    TypeError: 'undefined' is not a valid argument for 'instanceof' (evaluating 'proxy instanceof Ext.data.proxy.Memory')

    It seems to be a problem with the static data in the store. Any help will be appreciated.

    Thanks


    Code:
    Ext.application({
        name: 'Test'
    });
    
    
    // Changed Ext.regModel to Ext.define
    Ext.define('Contact', {
        extend: 'Ext.data.Model',
        fields: ['firstName', 'lastName']
    });
    
    
    Ext.create('Ext.data.Store', {
        id: 'ListStore',
        model: 'Contact',
        sorters: 'firstName',
        getGroupString : function(record) {
            return record.get('firstName')[0];
        },
        data: [
            {firstName: 'Julio', lastName: 'Benesh'},

    Which ST file are you using from the SDK? sencha-touch.js? Try using the sencha-touch-all-debug.js file from the SDK instead.

    Default Workaround

    Workaround


    I'm using sencha-touch-debug.js, so I'll try sencha-touch-all-debug.js and see if it helps with debugging. However, this looks like a bug to me. With 1.x I didn't need to explicitly create a proxy to read inline data.

    Here's the workaround I'm using for now:

    Code:
    Ext.create('Ext.data.Store', {
        id: 'ListStore',
        model: 'Contact',
        sorters: 'firstName',
        getGroupString : function(record) {
            return record.get('firstName')[0];
        },
    
    
        data: [
            {firstName: 'Julio', lastName: 'Benesh'},
            {firstName: 'Julio', lastName: 'Minich'},
            {firstName: 'Tania', lastName: 'Ricco'},
            {firstName: 'Odessa', lastName: 'Steuck'},
            ...
        ],
    
    
        // 2.0 Workaround to load data
        proxy: {
    	    type: 'memory',
    	    reader: {
    	        type: 'json',
    	        root: this.data
    	    }
    	}
    });
