REST-store performs un-wanted POST's on init.

I'm having issues with a REST store.

It's configured with autoSync: true and performs unexpected and unwanted POST and PUT-operations.

When my application loads, the store loads and begins with firing a POST with empty data after that it loads the backend data.

With autoSync: false in starts up like expected, ie no POST-operation.

Why does this happen?

The store is empty and the record it's trying to sync back doesn't even exists!

MODEL

Code:

Ext.define('Archive.model.Directory', {
    extend: 'Ext.data.Model',


    requires: [
        'Ext.data.field.Integer',
        'Ext.data.field.String',
        'Ext.data.field.Boolean',
        'Ext.data.proxy.Rest',
        'Ext.data.reader.Json',
        'Ext.data.writer.Json'
    ],


    fields: [
        {
            type: 'int',
            name: 'id'
        },
        {
            type: 'string',
            name: 'name'
        },
        {
            type: 'int',
            name: 'games'
        },
        {
            type: 'boolean',
            name: 'leaf'
        }
    ],


    hasMany: {
        model: 'Archive.model.Directory',
        name: 'children'
    },


    proxy: {
        type: 'rest',
        extraParams: {
            otype: 'user',
            oid: 1
        },
        url: '/api/v1/archive/directory.php',
        appendId: false,
        reader: {
            type: 'json',
            rootProperty: 'data'
        },
        writer: {
            type: 'json'
        }
    }
});

STORE

Code:

Ext.define('Archive.store.Directory', {
    extend: 'Ext.data.TreeStore',


    requires: [
        'Archive.model.Directory'
    ],


    constructor: function(cfg) {
        var me = this;
        cfg = cfg || {};
        me.callParent([Ext.apply({
            storeId: 'Directory',
            autoLoad: true,
            autoSync: true,
            model: 'Archive.model.Directory'
        }, cfg)]);
    }
});
