    Default Problem with DirectStore

    Hello.
    I am trying to use Direct b DirectStore in my application, but I have some problems with them.

    I write in MVC style and add in my app.js file this:
    Code:
                    Ext.direct.Manager.addProvider({
                        'type': 'remoting',
                        'url': '/places/remoting/router/',
                        'namespace': 'Recruitant.places',
    
    
                        'actions': {
                            'city': [
                                {
                                    'formHandler': false,
                                    'name': 'load_cities',
                                    'len': 1
                                }
                            ]
                        }
                    });
                    Recruitant.places.city.load_cities();
    This code work fine, but I try to define Model like this:
    Code:
    Ext.define('Recruitant.model.City', {
        extend: 'Ext.data.Model',
    
    
        proxy: {
            type: 'direct',
            url: '/places/remoting/router/',
            directFn: 'Recruitant.places.city.load_cities'
        },
    
    
        fields: [
            {name: 'id', type: 'int'},
            {name: 'name', type: 'string'}
        ]
    });
    and DirectStore like this:
    Code:
    Ext.define('Recruitant.store.Cities', {
        extend: 'Ext.data.DirectStore',
        model: 'Recruitant.model.City'
    
    
    });
    and in my firebug have error "fn is undefined".

    Help me to solve this problem, please.

    Default

    My code works if I create grid, store and other objects in app.js, but it is not work if I write Store, Model and other stuff with Ext.define.

    On the client side, remove the quotes around the directFn specification: it needs to be a function, not a strong.


    You have:
    directFn: 'Recruitant.places.city.load_cities'

    You should have:
    directFn: Recruitant.places.city.load_cities

    @oniseijin - not true, docs say: "The directFn may also be a string reference to the fully qualified name of the function, for example: 'MyApp.company.GetProfile'. This can be useful when using dynamic loading. The string will be looked up when the proxy is created."

    I am using it as a string in my application now and it is necessary in case the JS gets loaded out of order, although I have gotten intermittent errors about the directFn is null whether I use the string or function symbol format
