Lothar,
good point but i think that's the beauty of GWT code,
they already have one parameter(timeoutMillis) in following call( i
have not tested it, if it works or not but i guess it will work.)
Request request = new Request(xmlHttpRequest, timeoutMillis,
callback);
So if call doesnt get finish in that time it will timeout and your UI
will be working fine.
I am copy pasting the full function here
private Request doSend(String requestData, RequestCallback callback)
throws RequestException {
JavaScriptObject xmlHttpRequest = httpRequest.createXmlHTTPRequest
();
String openError;
if (user != null && password != null) {
openError = XMLHTTPRequest.open(xmlHttpRequest, httpMethod, url,
true,
user, password);
} else if (user != null) {
openError = XMLHTTPRequest.open(xmlHttpRequest, httpMethod, url,
true,
user);
} else {
openError = XMLHTTPRequest.open(xmlHttpRequest, httpMethod, url,
true);
}
if (openError != null) {
RequestPermissionException requestPermissionException = new
RequestPermissionException(
url);
requestPermissionException.initCause(new RequestException
(openError));
throw requestPermissionException;
}
setHeaders(xmlHttpRequest);
Request request = new Request(xmlHttpRequest, timeoutMillis,
callback);
String sendError = XMLHTTPRequest.send(xmlHttpRequest, request,
requestData, callback);
if (sendError != null) {
throw new RequestException(sendError);
}
return request;
}
