Titanium Appcelerator - HTTPClient - onload - custom exception - exception

Question

I am using Titanium Studio (build: 3.4.0.201409261227) and I am trying to catch an exception within the "onload" callback of Ti.Network.HTTPClient.
But that's not possible, I am getting the "Red Screen" with "Application Error" and I am not able to catch the exception.
Anyone an idea?
try {
var tiHTTPClient = Ti.Network.createHTTPClient({
onload : function(e) {
throw 'EXCEPTION';
}
});
tiHTTPClient.open( 'GET', 'http://www.google.com' );
tiHTTPClient.send();
}
catch( e ) {
alert( 'E: ' + e.message );
}
Outside the "onload" function, it's easily possible via:
try {
throw 'EXCEPTION';
}
catch( e ) {
alert( 'E: ' + e.message );
}

Answer 1

This might be the correct answer or at least the explanation :
BTW, the reason your try...catch blog makes no difference is that "invoke" succeeds -- it's an asynchronous call so it just returns control immediately, and you therefore pass right through the try block without any problems.

And one solution could be:
var exceptionHandling = function( msg ) {
alert( 'E: ' + msg );
};
var tiHTTPClient = Ti.Network.createHTTPClient({
onload : function(e) {
exceptionHandling('EXCEPTION');
}
});
tiHTTPClient.open( 'GET', 'http://www.google.com' );
tiHTTPClient.send();
