Description

When an invalid url is loaded from a webview, no error event is generated. An error event is generated in iOS. Steps to Reproduce: 1. Run code, click 'Open Invalid URL'.

var win = Ti.UI.createWindow({
	backgroundColor:'blue'
});

var buttonGoogle = Ti.UI.createButton({
	title:'Open Google',
	top:'20%',
	height:'30%',
	left:'10%',
	right:'10%'
});

buttonGoogle.addEventListener('click', function(){
	var webView = Ti.UI.createWebView({
			url:'http://www.google.com'
		});
	
	webView.addEventListener('load', function(){
		alert('load: ' + webView.url);
		});
	
	webView.addEventListener('beforeload', function(){
		alert('beforeload: ' + webView.url);
		});
		
	webView.addEventListener('error', function(){
		alert('error: ' + webView.url);
		});
		
	win.add(webView);
	
	var button = Ti.UI.createButton({
		title:'Close',
		right:0,
		bottom:0,
		height:'10%',
		width:'20%'
	});
	
	button.addEventListener('click', function(){
		win.remove(webView);
	});
	
	webView.add(button);
});

win.add(buttonGoogle);

var buttonInvalid = Ti.UI.createButton({
	title:'Open Invalid URL',
	bottom:'20%',
	height:'30%',
	left:'10%',
	right:'10%'
});

buttonInvalid.addEventListener('click', function(){
	var webView = Ti.UI.createWebView({
			url:'http://xxx'
		});
	
	webView.addEventListener('load', function(){
		alert('load: ' + webView.url);
		});
	
	webView.addEventListener('beforeload', function(){
		alert('beforeload: ' + webView.url);
		});
		
	webView.addEventListener('error', function(){
		alert('error: ' + webView.url);
		});
		
	win.add(webView);
	
	var button = Ti.UI.createButton({
		title:'Close',
		right:0,
		bottom:0,
		height:'10%',
		width:'20%'
	});
	
	button.addEventListener('click', function(){
		win.remove(webView);
	});
	
	webView.add(button);
});

win.add(buttonInvalid);

win.open();

Expected Result: One error event should fire. Actual Result: No error events fire.

'Error' alert fired only once but 'beforeload' alert fired 2 or 3 times inconsistently. When click on 'inavalid URL', observed steps 1.load alert fired 2.load alert fired again 3. beforeload alert 4.error alert 5. beforeload alert beforeload alert repeatedly fired instead of once. The problem reproduce with release 3.0.2 and master release 3.1.0 tested on Titanium Studio, build: 3.0.1.201212181159 Titanium SDK version: 3.1.0 Titanium SDK version: 3.0.2 Device: Samsung galaxy s duos Android version: 4.0.4 Android Emulator: Android SDK version: 2.2
