Little more information on this. The problem occurs when the page returns
and the url is different than it was when it left. Eg: It has some params.
Note, that is still has the gwt.codesvr param.
Also, the RPC call makes it to the server, it just doesn't make it back.
It falls into the onFailure.
This means we can actually work around the problem by grabbing all the url
params we need, doing the RPC, and then adding a check in the onFailure to
the redirect to the original url without the params.
Eg:
@Override
public void onFailure(Throwable caught) {
// Only when using the GWT plugin
if (GWT.isProdMode() == false) {
Window.Location.replace("<your original url>");
}
}
GWT bug bypassed! :-)
