Description

When the evalJS method of a WebView is called, the app will crash. Log attached. Steps to Reproduce: 1. Run code on 2.3.3 Emulator (WebViewTest project attached). Note: This is a minimal fail case. TIMOB-4885 provides a similar example.

var win = Ti.UI.createWindow();
var webView = Ti.UI.createWebView({ url:'test.html' });

win.add(webView);
win.open();

webView.addEventListener('load', function() {
	webView.evalJS("run()");
});

<!doctype html>
<html>
	<head>
		<title>WebView Test Page</title>
</head>
	<body><h1>WebView Test Page</h1>
	<script type="text/javascript">
			function run() { alert('WebView JS Eval'); };
		</script>
	</body>
</html>

Expected Result: An alert should appear indicating evalJS was successful. Actual Result: Crash.

This behavior is not limited to the evalJS method. Many Titanium API calls from the HTML cause the same crash, such as:

   <!doctype html>
   <html>
   	<head>
   		<title>WebView Test Page</title>
   	</head>
   	<body><h1>WebView Test Page</h1>
   		<script type="text/javascript">
   			Ti.API.info('WebView JS Log Info');
   		</script>
   	</body>
   </html>

   <!doctype html>
   <html>
   	<head>
   		<title>WebView Test Page</title>
   	</head>
   	<body><h1>WebView Test Page</h1>
   		<script type="text/javascript">
   			Ti.App.addEventListener('pause', function() {
   			
   			});
   		</script>
   	</body>
   </html>

However, some API calls do not crash the app, such as:

   <!doctype html>
   <html>
   	<head>
   		<title>WebView Test Page</title>
   	</head>
   	<body><h1>WebView Test Page</h1>
   		<script type="text/javascript">
   			Ti.Platform.getOsname();
   			Ti.App.getVersion();
   		</script>
   	</body>
   </html>
