Synchronous Ajax Call

[mitchellsimoens]

Just a note for the Ext JS 4.x users... Ext.Ajax.request support synchronous calls natively:

Ext.Ajax.request({
    url      : 'something.php',
    async    : false,
    callback : function(opts, success, response) {...}
});

hi, I want to create a synchronous ajax call by Ext.data.AjaxProxy in sencha touch 2.
but in sencha-touch-all-debug.js,the implementation of Ext.data.AjaxProxy didn't set an async parameter.

request.setConfig({
	headers        : this.getHeaders(),
	timeout        : this.getTimeout(),
	method         : this.getMethod(request),
	callback       : this.createRequestCallback(request, operation, callback, scope),
	scope          : this		
});

so I create a new define Ext.data.AjaxProxySync, and I add a config parameter,and set this parameter as false.

Ext.define('Ext.data.proxy.AjaxSync', {
    extend: 'Ext.data.proxy.Server',

    requires: ['Ext.util.MixedCollection', 'Ext.Ajax'],
    alias: 'proxy.ajaxsync',
    alternateClassName: ['Ext.data.HttpProxy', 'Ext.data.AjaxProxySync'],

    config: {
        actionMethods: {
            create : 'POST',
            read   : 'GET',
            update : 'POST',
            destroy: 'POST'
        },
        headers: {},
        withCredentials: false,
        async          : false
    },
	
    doRequest: function(operation, callback, scope) {
        var writer  = this.getWriter(),
            request = this.buildRequest(operation);

        request.setConfig({
            headers        : this.getHeaders(),
            timeout        : this.getTimeout(),
            method         : this.getMethod(request),
            callback       : this.createRequestCallback(request, operation, callback, scope),
            scope          : this,
			async          : this.getAsync()		
        });

        if (operation.getWithCredentials() || this.getWithCredentials()) {
            request.setWithCredentials(true);
        }

        // We now always have the writer prepare the request
        request = writer.write(request);
		console.log('request.getCurrentConfig\n');
		console.log(request.getCurrentConfig());
        Ext.Ajax.request(request.getCurrentConfig());

        return request;
    },

    //...,the same as Ext.data.proxy.Ajax
});

but in the implement of request.setConfig(),async parameter will be push out.

if (name in defaultConfig) {
	configList.push(name);
	nameMap = configNameCache[name];
	this[nameMap.get] = this[nameMap.initGet];
}

in this section, async parameter is not in defaultConfig,so I fail.
can you tell me how to config the defaultConfig value or other solution?thank you very much!
