Sencha Touch 2.1 marks Ajax JSON response as failed if server returns empty array

[NineBerry]

We hit upon the same problem. Should be fixed in an upcoming version of Sencha Touch

I haven't updated my app yet, but looking at the source code it looks like this issue hasn't been fixed in 2.2.0.

It's closed, so unless somebody reopens it again it will never get fixed.

This bug also affects stores using memory proxies. Then you can just do:

store.setData([]);

and immediately see it ignored, and the previous value retained. I'm still seeing this in sencha 2.2.1. I fixed it with an override of Ext.data.reader.Reader, but that's a pain to maintain.

It's obvious that no data is a valid, non-error condition, and shouldn't be treated as an error.

I'd like to second this bug. It's not just with Ajax proxies; it affects all proxies. Here's an example:

Ext.define('User', {
    extend: 'Ext.data.Model',
    config: {
        fields: [
            {name: 'id',    type: 'int'},
            {name: 'name',  type: 'string'},
            {name: 'phone', type: 'string', mapping: 'phoneNumber'}
        ]
    }
});

var store = Ext.create('Ext.data.Store', {
    model: 'User',
    data : [],
    proxy: {
        type: 'memory',
        reader: {
            type: 'json'
        }
    }
});

store.load({
	callback: function(records, operation, success) {
		console.log(success); // logs "false"
	}
});
