Description

Steps to reproduce: 1. Run the code attached below. 2. Two alerts show which means the "load" event is fired twice. Expected behavior: load should be only fired once. Note: i) if commenting out webview.setHtml("xxx") but use webview.html="xxx", the "load" event will be only fired once. ii) if running on Galaxy Nexus (4.0.4), a warning shows in the console, like {quote} W/webview ( 2264): java.lang.Throwable: Warning: A WebView method was called on thread 'KrollRuntimeThread'. All WebView methods must be called on the UI thread. Future versions of WebView may not support use on other threads. {quote}

var _window = Ti.UI.createWindow({
	backgroundColor : '#000'
})

var webview = Ti.UI.createWebView({
	top : 0,
	height : 200
});

webview.setHtml('<html><body>test</body></html>');
//webview.html = '<html><body>test</body></html>';

webview.addEventListener('load', function() {
	alert('The webview is loaded!');
});

_window.add(webview);
_window.open();
