I don't see anything obviously wrong with your code, but here is a
snippet of my code which does the same thing and works fine.
Note I use RequestBuilder.GET and have a couple of extra error checks
- might help point to a problem.
==============
url = URL.encode(url);
RequestBuilder builder = new RequestBuilder(RequestBuilder.GET, url);
try {
@SuppressWarnings("unused")
Request request = builder.sendRequest("", new RequestCallback()
{
public void onError(Request request, Throwable exception) {
fireErrorEvent("Couldn't retrieve info");
}
public void onResponseReceived(Request request, Response
response) {
if (200 == response.getStatusCode()) {
//200 means all ok, so do something with
response.getText()
}
else if (0 == response.getStatusCode()){
fireErrorEvent(response.getText());
}
else
{
fireErrorEvent("Couldn't retrieve data (" +
response.getStatusText() + response.getStatusCode() + ")");
}
}
});
}
catch (RequestException e) {
fireErrorEvent("Couldn't retrieve info");
}
==============
