JavaScriptException when upgrading SmartGWT

Hey Isomorphic,

I'm in the process of attempting to upgrade from SmartGWT 3.1 to SmartGWT 4.0 and receive the following Error (characterized by the following stack trace) below:

ERROR: Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (TypeError) @com.google.gwt.core.client.impl.Impl::apply(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)([JavaScript object(1305), JavaScript object(1303), JavaScript object(1313)]): isc.isA.SGWTFactoryObject is not a function

This occurs in the LGPL edition of SmartGWT 4.0, built on December 17, 2013. All browsers are affected, as this is a problem that is thrown on startup of the application and causes the load to fail completely.

The company I work for uses SmartGWT for a number of applications and a number of others work fine with the new (4.0) files, but this one obviously does not. Please tell me if you would like any sample code posted, as I am unsure what code you might need to aid me in debugging this issue, seeing as the stack trace is a bit unhelpful.

Thank you!
