Getting com.google.gwt.user.client.rpc.StatusCodeException: 0 in GWT

Question

I sometimes/often get this Exception in GWT but don\'t know why:

SEVERE: com.google.gwt.user.client.rpc.StatusCodeException: 0 
java.lang.RuntimeException: com.g         


        

Answer 1

I have found that if you hang an rpc call on the server (Thread.wait()) and the browser is refreshed then on the client side just before it loads the page again it will call the onFailure method of the waiting callback with the above mentioned status code which suggests it orginates in the client or that it is a generic error code for non-specific caught exceptions.
