Re: The GWT application hangs on the loading screen
Hi Jeff, all,
your advice was very helpful to me, thanks a lot.
I put an alert message at the first line of your onModuleLoad method.
I put 3 more alert message in the entrypoint classes defined within the 3
gwt.xml files. I did this work first locally, where the project goes up
without problems and then I deployed the war on the cloud.
Locally the 3 warning messages inform me that the 3 entrypoint classes are
called. But this does not happen in the distributed application. Only the
MyWorkspace class containing the onModuleLoad() method is called and then
it enters a sort of loop, always loading the same class and never the 3
entrypoint classes.
Please, do you know why this happens?
This is all happening following an upgrade from GWT 1.5 to GWT 2.7.0, with
jdk 1.8.
Thanks in advance,
Antonio

Hello everyone and thanks for the advice you are giving me.
The nocache.js file is regularly generated and loaded. I don't think I
have a problem with the URI because I can also see the home page grid but
nothing more. No errors appear in the developer tool. Note that I upgraded
from GWT 2.1 to GWT 2.7 and before that I had no problems.
Can you give me some other suggestions?
Thanks again.

Hi all. I deployed an app using GWT on Cloud. It's deployed and
working, but when you log in, the browser window just says "Loading"
and
seems to hang indefinitely. Works fine locally in Eclipse.
Has this ever happened to you? Is there anyone who can help me
understand why this happens?
Many thanks

Re: The GWT application hangs on the loading screen
There might be an error in the actual code of the app (exception or other).
I suggest you try some primitive debugging with a Window.alert message as
the first line of your onModuleLoad method.
ie...
@Override
public void onModuleLoad() {
Window.alert("App is starting");

Hi Frank, thanks for the support.
No errors appear in the application logs of the application nor in the
Develop Tool. The nocache.js file is successfully loaded. What else could
it be?

Anyway, I always check in Developer Tools in Chrome to make sure there
