Unfortunately, the stack trace is not helpful without the exception's "cause". Could you add a GWT.UncaughtExceptionHandler that shows the getCause() ?
Anyway, it's something to do with a PlaceChangeHandler throwing an exception (that one being in the getCause() or the UmbrellaException; there might be several such exceptions though, that's what UmbrellaExceptions has a getCauses(), but you could nuke them one at a time). One line that might help: at Unknown.de_systemagmbh_dfs_client_factory_AbstractClientFactory $1_fireEvent__Lcom_google_gwt_event_shared_GwtEvent_2V(Unknown Source) An inner class in your AbstractClientFactory has a fireEvent, that might be the source of the error. Maybe you could share some light as to why you have a custom PlaceController, PlaceHistoryHandler and Historian? (and is that inner class a custom EventBus?) -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
