Hi

I'm running the GWT MVP example (http://code.google.com/p/google-web-
toolkit/downloads/detail?name=Tutorial-Contacts.zip) from the
SpringSource Tool Suite with AppEngine 1.4.0 and GWT SDK 2.1.0. When
it calls a method on com.google.gwt.user.client.History
(addValueChangeHandler or getToken in particular), I get the following
exception:

com.google.gwt.dev.shell.HostedModeException: Something other than a
boolean was returned from JSNI method
'@com.google.gwt.user.client.impl.HistoryImplTimer::init()': JS value
of type JavaScript object(6), expected boolean

Is this an error in HistoryImplTimer::init(), in the sample code or
something else?

Thank you
